Lsi 48 a ariston DIY repair

it was written on it stood right next to this resistor. Still, I don’t understand V001 a bun with 2 legs (K275 on it) was pressed against the resistor and also burned out. I do not know what else to write, if someone shares the circuit (at least its high-voltage part) I will be very grateful, if no one else has it, I will continue to write what goes where.
Thanks in advance.
P.S. I did not go deep because if there is a circuit, I think that's enough.

Bun, this is a 275 volt varistor.

Thanks, figured it out. The phase enters this board through that 100 ohm resistor, and after it there is a burned-out condender to zero. I think everything is simple, the knder struck and the phase after 100 ohms closed to zero. I'll check and write, maybe someone will come in handy.

Sorry, I had to leave unexpectedly. The situation is this: I changed everything, I turn on it drains the water, pours it in, starts washing, washes the mines. 15 then stops, from above the indicator jumps to the last right icon and flashes evenly (fig. Red fork, knife, plates, avto). Further nothing happens. If you turn it off, then when you turn it on, the indication of the previous not completed program lights up (it does not flash). I tried to run different programs, it ends in the same way, as described above. What do you advise ?

Maximum filling time exceeded, 6 min.

With all due respect, this is not the case. I checked it 2 more times, the water supply ends in less than a minute. The first time the car worked for about an hour and got up, the second about 45 minutes, drained the water and got up. Both times, as before, the indicator jumps to the last right icon and blinks evenly. I checked the "glass" on the program. I really hope for your advice.
Best regards, Maxim.

I forgot completely, I took it off again yesterday, the same capacitor was leaning against the resistor and again slightly scorched, does the resistor overheat the capacitor for the first time?
Here are the data from the side LI 48 A 37272460000 S / N 205294001, TYPE NUMBER LD 08-BIT100.
I would be very grateful for help at a distance.

islavskoe46, you were told everything by the error code, check and treat.

In the title of the topic it is supposed to write a malfunction, but I could not find another definition - the machine is "buggy", more precisely, the programmer does not always work.

The power button works, you start switching programs, the indicators (such as programs and turn-on delays) may go out, after 5-10 seconds and a few clicks on the “P” button, the indicator lights up again.
If you can start the machine, the program can run without crashing, but it can stop (the program type indicator goes out), or it can throw an error - most often 3 or 1.
The machine does not leak (there are no signs of leakage in the pallet); NTC has a resistance of 47kΩ at room temperature.

Tell me where to look for the malfunction - in the programmer or in the block with buttons

Where is the Zener diode located?

When inspecting the programmer board, a non-contact of the input resistor (47kΩ) was found on the “Polisher led switch” sensor ... - the sensor worked, but the defect remained.
Can anyone point out the ratings of the input circuits on a 6-foot connector (3-probe connector - NTC, salt, “Polisher led switch”)?

I recently made such a dishwasher. Most likely the case is in the low-voltage power supply. As far as I remember, there it is implemented on a transistor soldered to the board, and the soldering point acts as a heat sink and everything on my board was in rainbow colors from overheating. It is necessary to check with an oscilloscope what is happening there on the power supply of the processor.

Gone are the days when dishwashers were rare.
Accordingly, repair services are also gaining momentum.

We think it will be interesting for you how to save on breakdowns and not call the master.
How to repair the Ariston dishwasher with your own hands will be discussed in our article.

Execution options can be on BIT100 and DIWA boards.

Moreover, it can be dishwashers Ariston and Indesit.

Consider dishwashers assembled on an EVO3 electronic board.
For example, these are ARISTON models LV 46 A, LV 62, LV 620, LV 67 DUO, LV 670, L 63, L 65

These machines are provided with software protection and indication in case of malfunctions.

Signaling "Water tap closed" (short beeps sound and the second and third indicators on the right are blinking).
Filter clogging alarm (the second and fourth from the right indicators are blinking).
Signaling of a malfunction of the water supply solenoid valve (the third panel from the right flashes).

Versions with a programmer, with an LED display, with a liquid crystal screen.

Depending on the Ariston model (see figures), in case of a malfunction, an error code is displayed, an alarm sounds.

To check the devices, you can start the service mode.

1.Turn off the machine and wait 30 seconds (reset) - the door is closed.

2. Switch on and set program 1 (where the programmer set position 1), switch off and wait 30 seconds.

3. Switch on and set program 2, switch off and wait again for 30 seconds.

4.Turn on, indicators 3 and 6 will light up for LED models, 1 and 4 - with a selector.

5.Choosing a testing or autotesting program:

- turn the selector one position, press the P button once (20 minutes)
- turn the selector two positions, press the P button twice (4 minutes)

Error codes for dishwashers with BIT 100 module (malfunctions):

Dishwasher breakage causes a flurry of emotions, but do not rush to despair. Our publication will help you troubleshoot Ariston dishwashers with your own hands. An error code on the display can point to them, and each problem has its own “symptoms”.

We will teach you how to distinguish and eliminate breakdowns of the Hotpoint-Ariston dishwasher.

Ariston PMM error codes are collected and described in detail in a separate article.

There may be several reasons why the dishwasher does not work. As mentioned above, you need to pay attention to the "symptoms" of breakage. Let's take a closer look:

• PMM Ariston does not heat water. The reason may be a broken heating element. It is necessary to check the wiring leading to the heating element, the heater itself and the thermostat. The latter helps to measure the temperature of the water, so in the event of a breakdown, it needs a replacement.

• When the machine does not draw water, you need to check the presence of water in the water supply. Sometimes the reason is a blockage in the inlet hose or filter mesh. Notice that the dishwasher is bad for your dishes? Check the nozzles on the spray arm for clogging.
• Water is constantly poured and drained into the dishwasher. Such a malfunction indicates problems with the filler valve. Its membrane does not close, so water constantly flows, while the indicator flashes, notifying of a breakdown. The reason may be in the level sensor, which is responsible for monitoring the water in the tank.

• The machine makes noise during operation, the water does not drain. The rocker arms could be clogged, or the pump broke.
• The drain and inlet hose could be the cause of the machine leaking. Depressurization of the case or door, could also serve as a water leak. Need a thorough inspection and replacement of parts.

• Your Ariston dishwasher won't start or turn on? Plug another device into its outlet. If it does not work, then there is a breakdown in the outlet. Next, check the on-board switch. Ring the contacts of the switch, in case of malfunction, replace it.

If your car is still under warranty, then it's not worth solving problems yourself. Better to contact the service center.

In some cases, you can fix the breakdown yourself. Before starting work, disconnect the Ariston machine from the network and communications. Prepare the necessary tools.

Heating elements often suffer from scale when using hard water. If you hear an unpleasant burning smell, you need to check the heating element wiring, which could burn out.Are you sure the Hotpoint-Ariston heater is defective? Then proceed with the replacement:

1. Open the door of the hatch where the dishes are loaded.
2. Remove all trays and shelves.
3. Remove the water spray by pulling it up. It is located at the bottom of the car.
4. Below is a filter that protects the pump from dirt. Unscrew the part and remove the mesh from the bottom.
5. Remove the bolts that secure the pipe and heater.
6. Place the dishwasher on its side with access to the bottom.
7. If the machine is freestanding, remove the rear panel by unscrewing the mounting bolts. If the device is built-in, remove the bottom.
8. A pump is attached to the side of the heating element. You need to unscrew it clockwise. Disconnect the pump wiring and pull it out of the housing.
9. Disconnect the rubber fasteners of the heater and remove the heating element.

Tip: To make the correct wiring, take a photo of the connectors before removing the item from the slot.

Run the clipper after the repair to test the new element.

When water does not enter the Ariston dishwasher, or, conversely, is constantly being poured, check the intake valve. The part cannot be repaired, so you will need to disassemble the PMM:

• Remove the side or back panel (depending on the model) of the dishwasher.
• The valve is located just behind the inlet hose.
• Unscrew the valve fasteners, disconnect the wiring.

• For replacement, a part is selected for a specific model of a dishwasher.

The pressure switch could also break. The reasons for its breakdown are natural wear and tear, burning of contacts, blockage in the pressure tube.

How to disassemble the car and get to the sensor:

1. Access the bottom of the dishwasher.
2. Find the level sensor. It looks like a box of pipes.
3. Remove the two mounting bolts.
4. Remove the tube from the box using pliers.
5. Examine the reservoir (box) for pressure.
6. Check the electrical part of the pressure switch by measuring the resistance at the contacts.
7. If broken, install the new part in reverse order.

It is not difficult to make a replacement with your own hands. Be careful, follow the recommendations.

Below are instructions for replacing the drain pump (pump) of the dishwasher. In this repair, the main thing is to properly disassemble the dishwasher.

• Open the hopper door of the machine.
• Empty shelves and baskets out of the bin.
• Pull out the bottom filter as well as the metal mesh.
• Unscrew the inlet hose.
• Putting the machine on its "back", remove the bottom cover. To do this, unscrew the screws around the perimeter.

• Disconnect the wiring connectors from the pump.
• Use pliers to open the drain hose clamp. Disconnect it from the pump.
• Unscrew the fastening screw, remove the pump assembly.
• Reinstall a new pump with a rubber seal. Connect the wiring.

Note that there is a circulation pump (motor) next to the drain pump. If the pump only drains water, then the pump drives it through the car, delivering it to the sprinklers.

If PMM "Ariston" does not wash the dishes, the reason may be in the wash pump. We have described how to get to the drain pump above. Then do this:

• Remove the drain pump first.

• Disconnect the pump motor wiring.
• Release the motor mount.
• Release the metal hose clamps that attach to the circulation pump (three hoses in total).

• After pulling it out of the body, you need to remove the spring at the bottom and rearrange it to a new part.
• Turn the spring clockwise and remove.
• To install a new engine (wash pump), you need to remove the old hose clamps and install new ones.
• Fix the device in the reverse order.

So you can independently cope with the repair of the Ariston brand dishwasher. Pay attention to the operation of your equipment, if you notice deviations - conduct an inspection.

Good day!
The situation is as follows. We have a dishwasher Ariston Lsi 48 A. The machine is working (fills, drains, heats up the water) it works, it works, then once - and the light blinks (program failure). We assume that instead of turning on the drying, it has some kind of glitch and it just drives the water. The master was summoned.He said that it was necessary to change the electronic board - the point is in it. Found for 3100. Changed. Problem still exists. Another was summoned. He said that this is some kind of loop to this board and that the price of the issue needs to be changed - 2000 part + 790 work). The husband dismantled this thing in the evening, rubbed it there, it seemed to start working normally again. Yesterday I launched it for the first time - a glitch. After five minutes, I started it again - the program was completed to the end. Today is the same again. Can someone tell me what could be the matter? Tired of throwing money on the craftsmen who really can't determine the reason. Thanks in advance for your feedback! (Maybe she wrote messy, sorry).

really no one can help ((((((((((((

Dampness on the contacts (loop, board) probably.
In Chip-Dip (such a store) there are sprays to protect against moisture.
But these are only assumptions.

I have LSI68. A similar misfortune happened when the water supply to the upper rocker leaked out and water got into the lower pan. Thus, the leakage protection was triggered.
And don't, ZER, drive the Ariston. If it hadn't been for that, I would have flooded the neighbors. Determined the leakage by visual inspection of the rear end during the operation of the machine.

A dishwasher breakdown causes a storm of unpleasant emotions, forcing the owners to wash the dishes by hand, albeit temporarily. The first decision that comes to mind is to call your friends. There is a possibility that they faced such a problem. Alternatively, you can start looking for a solution to the problem on the Internet. That is why we decided to write an article on how to repair Ariston dishwashers. Let's figure out what most often fails, how to fix the malfunction, in which cases it is easier to contact the master.

Ariston dishwashers are similar in design and repair features to such Bosch and Electrolux dishwashers. However, not always the breakdowns that happen to the "Bosch" can happen to the "Aristons". Of course, as in other equipment, dishwasher parts are subject to wear and tear, but still the following malfunctions occur most often in Hotpoint Ariston dishwashers:

• failure of the heating element, which can lead to poor-quality dishwashing, as well as knocking out plugs of the electrical network;
• water intake into the machine is very slow or absent, the reason for this is a blockage or breakdown of the filler valve;
• drainage of water with a non-stop set, this malfunction is also a consequence of a breakdown of the filling valve or water level sensor;
• the dishwasher makes unusual noise and sounds, this indicates either a blockage of the rocker arms inside the tank of the machine, or a malfunction of the circulation pump;
• a water leak in the machine informs about a breakdown of the drain pump, a leak in the hose or a loosely closed door;
• the lack of drainage also indicates a breakdown of the drain pump and clogged filters.

Important! If you try to solve any problem with the dishwasher that is under warranty, you will void the warranty service.

A malfunction of the heating element in Ariston dishwashers is most often manifested by the appearance of an unpleasant odor. In this case, there may be no error on the display of the machine, the water heats up to the desired temperature, the machine works normally, the dishes are well washed. In fact, the appearance of the smell alone should be a warning to you of danger. After all, this is the smell of burnt wires, further melting of the insulation can lead to a short circuit and a fire.

What is to be done in this case? Let's describe all the steps in sequence:

1. First, the dishwasher must be disconnected from the electrical network, water, sewer and pulled out for ease of operation.
2. Next, disassemble the walls, if any, if necessary, marking with a marker where the screws should be, this will help not to get confused during assembly.
3. Under the soundproofing material of the right wall of the Ariston dishwasher there are wires going to the flow-through heating element, they need to be inspected for burnout.
4. The heating element itself is located on the side of the bottom and looks something like in the photo, usually the terminals of the heating element burn out, circled in a red circle. You cannot replace them separately, so you will have to completely change the entire ten.
   
5. Having released the clamps, you need to remove the heating element and connect a new one in its place, this should not cause any difficulties.

Important! To secure the new heating element, four new clamps are required, since the old ones cannot be reused. Self-replacement of this unit will cost you about 3000-4000 rubles.

After installing the heating element, it is necessary to run the shortest sink. To check the tightness of the connections and how the machine works.

If everything is in order, then assemble the dishwasher and put it back.

In the event of a malfunction of the filling valve, water is constantly drawn into the machine and immediately drained, or water does not enter the dishwasher at all. The contacts in the valve can burn out, the performance of which is checked with a multimeter, or the shutter can jam in the "open" or "closed" position. In both cases, the valve will have to be replaced. This is not difficult to do.

The water inlet valve is located inside the dishwasher just behind the inlet hose connection. Depending on the model of Hotpoint Ariston dishwasher, you will have to remove the side panels of the machine and the back wall.

For your information! When typing and constantly draining water, an error F5 appears on the display of Hotpoint Ariston dishwashers.

Constant water intake and drainage can also be caused by a faulty water level sensor. The pressure switch either itself fails as a result of prolonged operation, or the sensor contacts are oxidized. In case of oxidation, you can strip and update the wires with terminals. If the sensor itself breaks down, the pressure switch must be replaced. How difficult it is to do this, judge for yourself by studying the article, Replacing the water level sensor in the dishwasher.

Before deciding to replace the circulation pump and pump, you need to check them and make sure that these elements are faulty. It may turn out that one of these units is working, and we are already tuned in to expensive and dreary repairs. How to check for a malfunction of the circulation pump and the pump in the Hotpoint Ariston dishwasher?

• Disconnect the dishwasher from the mains and disconnect the inlet and outlet hoses.
• We put the rags somewhere in the free space in front of the dishwasher, and then slide the machine onto the rags so that you can put it on the back wall.
• Unscrew the rear bottom panel of the Hotpoint Ariston machine, and then place it on the back wall and unscrew the bottom.

Attention! When removing the bottom of the dishwasher, be careful with the anti-leakage sensor, do not pull off its wire.

• Now we have access to the required units.We take an ohmmeter, set the minimum value, and then put the probes on the contacts of the pump, and then the circulation pump.
• If the value on the ohmmeter display is about 1500, you can leave neither the pump nor the pump, most likely, the problem is not with them, but if the value is much lower, you may have to think about replacing these elements on the Hotpoint Ariston dishwasher.

We made sure that the pump does not work, we will change it. First you need to disconnect all wires and connectors from the pump and unscrew the drain hose. We unscrew one screw that holds the pump to the pallet. We take a new similar drain pump, install a new rubber O-ring and put a new pump in place of the old one. We fasten the drain hose, install the connectors and wires.

If there is a need to change the circulation pump, refer to the detailed instructions set out in the article How to replace a pump in a dishwasher?

Summing up, we note that it is quite possible to fix the Ariston dishwasher with your own hands, especially in cases when you have to deal with typical malfunctions that were discussed in this article. Happy renovation!

Washing machine Hotpoint Ariston of the Italian manufacturer is reliable and of high quality. But some parts of the washing machine sometimes become unusable.

You can, of course, send it to a service center for repair, but in order to save money and with skillful hands and a smart head, you can independently repair an electromechanical household appliance.

Do-it-yourself repair of the Ariston washing machine is easy to do. Follow our instructions for restoring the washing machine, and your assistant will serve you for many years.

• In the Ariston electromechanical device, the main reason for the incorrect operation of the machine is blockages.
• In addition, the heating element becomes unusable due to the appearance of limescale on the heating element due to hard water.
• The pump can also be faulty due to its long operation.
• Sometimes the filler valve fails due to damage to the rubber gasket.
• In rare cases, bearings and seals have to be changed.
• Electronics almost never breaks down, but we will still touch on the issue of replacing the control unit a little.

It is easy to remove the blockage with your own hands. You need to check the drain filter, which is located on the lower right under the panel.

After cleaning the filter, you will eliminate the cause of the malfunction of the washing machine. Less commonly, the drain pipe is clogged because it is thick.

There may be a blockage in the pump, but rarely, because there is an additional filter in front of it.

The drain hose will only become clogged if you have not installed it correctly.

Check the drain, there may be a blockage in it too. Disassemble the unit, pull out the branch pipe by loosening the clamps, flush it. Pull out the pump by unscrewing the fasteners and disconnecting the sensors.

Signs of a pump breakdown:

1. The drain pump hums, but the water does not drain.
2. The machine may stop when the system is running.
3. Water flows out slowly.

Repair of the pump of the Ariston washing machine must be done as follows:

If the filler valve is broken in Ariston, then water constantly flows into the washer, even when it is not working, it is disconnected from the network.

To check the filler valve, you need to unscrew the fasteners and remove the top cover. The valve is located where the drain hose connects to the body of the electromechanical unit.

Check the gaskets first. If they have not lost their performance, measure the resistance of the valve. Put the probes on the contacts of the filler valve and check the resistance, whether it is optimal (from 30 to 50 ohms).

If it is less or more than the set value, it means that the water intake valve is not working. To replace it, you need to unscrew the old valve from the body and screw in a new one. Be sure to connect the sensors.

If the heating element is faulty, then it is imperative to replace it. Its breakdown is indicated by the fact that the water does not heat up or washing in all programs takes place in cold water. Sometimes the machine gives an error and stops.

To replace the heating element, the rear wall must be removed. There are two contacts under the tank with a fastener in the middle. This is ten. Measure the resistance of the heating element with a multimeter.

If the resistance is within the normal range, then there is no need to change the heating element - it is serviceable. To remove the heating element, you need to unscrew the screw in the middle and pull it towards you with swinging movements.

The water may not heat up also due to the fragile connection of the wires to the heating element, which arises from the strong vibration of the washing machine. Water heating may also be absent if the temperature sensor is faulty.

Take a tester or multimeter and check the resistance of the sensor when cold and hot. If the resistance is the same, then it is broken, requires replacement. The resistance should be different.

The high-quality and durable material from which the drum of household appliances is made also becomes unusable, because solid foreign objects get into it, which can damage the unit, forming cracks on it.

The plastic rib inside the drum can deform. Remove the drum to replace it.

To remove the drum yourself, you need the following set of tools:

1. a set of screwdrivers, especially a Phillips screwdriver and a slotted nozzle are needed;
2. screwdriver;
3. pliers;
4. hammer;
5. hexagons of different sizes.

Use a Phillips screwdriver to remove the bolts from the back, front, and top walls, and then remove the panels themselves.

Dismantle the powder container. Use a slotted screwdriver to remove the module. It is not necessary to unscrew the control unit to the end, the main thing is that it does not interfere with the removal of the drum.

Remove the hatch cuff, pull out the lower bar by unscrewing the screws. It is necessary to dismantle electronics, shock absorbers and other parts from the loading tank.

Remove the drum from the device and disassemble it. Remove the screws holding the two sides of the drum. Pry the oil seals with a screwdriver and remove them.

The bearing in the drum can break and wear. It needs to be replaced. You only need to buy a bearing of the corresponding brand in a specialized store or order it on the official website of the Ariston washing machine, possibly purchase it in an equipment repair workshop.

Use a metal rod and a hammer to knock out the bearings. If they are defective, replace them. If the drum is deformed, replace it with a new one.

Reassemble. If the malfunction is in the plastic rib, then you do not need to disassemble the tank. The washer door is removed. A metal rod is taken, the diameter of which is smaller than the holes in the plastic rib of the drum.

The rod is inserted into one of the holes on the rib, the latch is opened with it, the plastic part is removed. A new plastic rib is put in its place. Slide along the groove with the plastic rib until the latch enters the hole and closes.
