Do-it-yourself Panasonic bread maker bucket repair

In detail: DIY repair of a bucket of a Panasonic bread machine from a real master for the site my.housecope.com.

In the life of many bread makers, there comes a moment when the bucket starts to leak. You can, of course, ignore the problem for a while, but over time it only gets worse. The shaft wobbles more and more, the blade scratches the bottom of the bucket, and then the shaft just falls out. This is the lot of most budget bread makers. Panasonic do not suffer from such things, but their one bucket is more expensive than an ordinary bread maker.

What are the options for a way out of this situation?

1. Throw this bread maker and go buy a new one.

Probably, this is the reaction of users that manufacturers are counting on. The resource of work is laid such that it will last for a little more than the warranty period.

Advantages: the easiest way.

Disadvantages: expensive and new flour of model selection.

Advantages: more budgetary than the previous one.

Disadvantages: sometimes even the same model of bread maker is equipped with different buckets. the mount may not fit, the size of the seat. The easiest way is to contact a service center, but it will cost more than buying it yourself.

3. Repair the bucket yourself.

Pluses: The most budgetary solution. After repair, the bucket becomes "eternal": you can maintain its performance as long as you like. Until you get bored.

Disadvantages: Requires the presence of more or less straight arms or the owner of those among friends. You also need some tool and basic skills to work with it.

I want to tell you about this third option in more detail.

The first step is to separate the bucket from the base with the shaft. Perhaps the most difficult operation in this matter, as it takes some care not to damage the bucket. But in any case, it will be possible to return to option number two.

Video (click to play).

I almost forgot, you need to put the risk on the base and the bucket, so that later you can put everything together correctly.

Somehow the rivets need to be removed. If you have a drill or screwdriver, you can drill them out.

You can grind off the protruding parts of the rivets with a file (file, grinder, sharpener), and knock them out.

After that, the lower part is easily detached.

We take out the worn out oil seal and measure it to order a new one. You can measure not the oil seal itself, but the shaft diameter (usually 8 mm) and its seat (18-20 mm).

The second difficult operation is the replacement of the metal-graphite sleeve. At the factory, it is inserted "hot", so it is impossible to knock it out without damaging the silumin base. I made cuts in the bushing with a jigsaw and it can be easily removed. This can be done with a file (long) or with a narrow hacksaw blade.

We measure the diameter and height of the sleeve.

And neatly, with light taps, we hammer in a new sleeve. It should protrude 1 mm from both sides.

If the “butterfly” is not riveted at the bottom of the shaft, then it is worth replacing it too. Then we get the "new bucket" state. You can also rip off a riveted butterfly, but this requires a slightly higher level of skill.

If the shaft falls out, then you need to buy an 8 mm retaining ring.

And here are the 10 mm M5 bolts. With washers, grovers or self-locking nuts.

One of the most common breakdowns in a bread machine is failure of the oil seal or bucket bearing.With such a malfunction, the oil seal may leak slightly, and the bearing may cause seizure or wedging of the shaft. Buying a new bucket of bread maker is not always the best idea, as it is not always the best idea. it costs quite a lot of money. Today we will clearly show how you can repair a bread maker with your own hands, namely, repair a bucket.

For clarity, we took one of the most popular bread makers. LG HB-155CJ... We begin to repair the bread machine by taking out the bucket and removing the retaining ring holding the metal washer with plastic paws on the shaft. The circlip, which secures the bearing, does not need to be removed at this stage.

The next step is to remove the bearing from the seat. You have to be very careful here - impacts can easily damage the bucketsince his material very fragile... To remove the bearing, it is rational to use a press or a small two-legged puller.

The stripper stops perfectly fit into the grooves of the body of such a bucket, in this position the stripper is fixed.

Putting a small plate 1-2mm thick under the bearing shaft and screwing in the puller axis, the bearing together with the oil seal push them out from the inside of the bucket.

As you can see, the oil seal and the bearing are in a very poor condition.

Then we remove the bearing retainers.

By the way, this is what is inside the bearing - not a trace of grease remained during operation.

Remove the bearing from the shaft and clean the shaft from contamination. It is best to use alcohol to flush and clean the shaft. petrol or thinner is not allowed here.

Next, we need spare parts: a new oil seal for the bread machine and bearing 608 (Dimensions: inner diameter - 8mm; outer - 22mm; height - 7mm). The oil seal is special, they are white, and it is better to take a purebred bearing (in our case, the manufacturer is FLT).

Further procedures are in reverse order. We install the bearing on the shaft and fix it.

We press the bearing into the seat. Impacts are not allowed, we use a press, we cool a bearing or heat a bucket, whatever you like, but just do not hit.

After installing the shaft with the bearing, we fix the washer with feet on the shaft.

The last step is to install a new oil seal.

At this stage, the do-it-yourself repair of the bread machine is completed, the oil seal and bearing have been replaced, it remains to clean the bucket.

It is not difficult to repair a bread maker, the main thing is to correctly approach this process. A home bread maker is a complicated device, but some breakdowns can be easily fixed on your own without taking it to a service center. The most common malfunctions of simple parts. If used correctly, a home bread maker will last for a long time. It is a very reliable household appliance. But, over time, repairs are still needed. This is due to wear of the device parts, or there is a malfunction in the electronics (software).

Some breakdowns can be repaired by hand. This applies to mechanical parts. The control circuit, sensors, all these problems are best left to the master to solve if any part is broken.

Most often, the following malfunctions occur:

  • Failure of the heating element;
  • Damage to the thermal sensor;
  • Engine breakdown;
  • Failure in the control program;
  • Cover problems;
  • Breakage of the bowl.

The bread maker should be repaired due to a broken bowl, a malfunction in the control program, and in some other cases.

If the heating element breaks down, the bread stops baking altogether. This can be checked by disassembling the device and checking the heater with a tester. If the breakdown is confirmed, the heating element must be replaced. The temperature sensor regulates the temperature during baking. Its malfunction leads to the fact that the bread either burns or is not baked. Replacing the thermal sensor is not difficult.

If the motor of the bread maker breaks down, the agitator remains stationary, and when turned on, its operation is not heard. In this case, it is better to consult a specialist.

Failure in the control program can be determined by the strange behavior of the device. The signal about the end of work turns on at the beginning of baking, some buttons on the control panel stop working, all this is the cause of the breakdown of the program module. Failures of the cover of the device often occur. It is not tight, or vice versa, it closes very tightly. In this case, you need to make sure that nothing interferes with the closure of the lid. If so, then the entire cover needs to be replaced. A common cause of bowl breakage is oil seal or bearing wear. If the gland is damaged, the bucket of the bread machine leaks, and if the shaft is jammed, the point is in the bearing.

To understand the cause of the malfunction of the device, it must be disassembled. Having decided to disassemble the bread maker, it is very important to carefully study the instructions and the diagram of the household appliance. Bread makers do not fundamentally differ from each other in their structure. The design of the Redmond, Saturn, Liberton or Moulinex device practically does not differ from Kenwood or Combustion.

The bread maker consists of:

In order to properly disassemble the bread maker, you must read the instructions

An electric motor is installed in the baking chamber, which rotates the shaft in the baking bowl, heating elements (heating elements) and a coupling. A non-stick baking dish is located in the baking chamber. There is a kneading spatula at the bottom of the bowl. It connects to the shaft. From the outside, the shaft is attached by means of a coupling with a motor.

With the help of a temperature sensor, the desired temperature is maintained during the baking process.

The choice of parameters, switching on and off the device is carried out using the control panel. The display is used to display information. Dismantling the bread maker begins with removing the cover of the device. Then you need to detach the panel. It is secured with bolts and plugs. Carefully unfasten the ribbon cable from the board, and then you can remove the bottom cover. Then we take out the heating element. Thus, the bread maker is divided into a body and a casing.

Some models, for example, Orion, are problematic to disassemble. The motor and belt in them are at the bottom, and in order to get to them, you have to disassemble the entire bread maker. After repairing and replacing the necessary parts, the bread maker must be reassembled in the reverse order. In order to assemble everything correctly, and not to get confused in the bolts and screws, they immediately need to be laid out in different boxes, and remember the order in which the device was disassembled.

During the operation of the bread makers, high temperatures act on the gland, it gets wet when washing the bucket, and dries up in a calm state. This leads to a loss of elasticity and elasticity of the rubber, and the oil seal breaks, the bucket of the bread machine begins to leak. Moisture gets on the bearing and starts to rust. Do not delay the repair of the bread maker. This can lead to more serious problems. Replacing the bucket with a new one will not be cheap, and you can change the bucket oil seal yourself.

Before you start replacing the oil seal, you should prepare the necessary tools and materials for work

For repair you will need:

  • New oil seal;
  • Retaining ring (must match the shaft diameter);
  • Graphite grease;
  • Tools to disassemble a bucket of bread maker.

We unscrew the fasteners of the base of the bowl. The shaft is attached to the bottom in the bread maker's bucket with retaining rings. Remove the shaft retaining ring. Carefully knock out the shaft with the bearing and the oil seal through a wooden support. Remove the bearing from the shaft.

We remove dirt and rust from the shaft. It is better to use alcohol for this.

Lubricate the shaft with graphite grease. Next, we put the bearing back on the shaft. Then we install it on the bottom of the bucket, and fix it with a retaining ring. We install a new oil seal from the inside of the bowl into the groove around the shaft. We turn the bucket over, and fix the clutch with a lock washer. That's it, now you can check the work of the bucket.

Problems with touch controls are very common.The control buttons on the panel stop working and an error is displayed on the screen. These unpleasant effects are due to moisture getting under the film. You can deal with such a problem yourself.

In order to properly repair a baking machine, experts recommend performing all actions step by step
  1. Place the bread maker on a flat surface.
  2. We clean it from fat, and peel off the panel. This should be done very carefully so as not to spoil the appearance of the device.
  3. Pry the sticker with a knife and carefully pull it up.
  4. Do not forget about the loop, on the LG bread makers it is on the right.
  5. Then carefully wipe the contacts with a soft cloth. They are located on the body of the bread maker and on the back of the control panel.

We use alcohol for cleaning. Wipe gently and thoroughly to get rid of dirt and grease that has got on the contacts. In order to prevent dirt from clogging up under the control panel during further operation, you can stick double-sided tape on the body along the perimeter of the panel-body connection.

After cleaning the contacts, close the touch panel. Checking the operation of the control panel. Typically, such repairs bring the panel of the bread maker back to life, and the buttons begin to respond to pressing.

For many, bread makers have long become indispensable helpers. Modern household bread makers are compact and fit easily in a small kitchen. A wide range of these household appliances allows you to purchase a model that is optimal in terms of price and performance. But, despite the variety of brands and models, bread makers have a similar principle of operation, and are assembled from the same parts.

The procedure for disassembly and repair is the same for almost all household bread makers. And many malfunctions can be dealt with on their own at home. Very often, the cause of a device malfunction is the breakdown of simple parts. It is quite possible to repair or replace them with your own hands and without contacting a service center. This will save money and time, because it is very difficult to do without the usual fresh bread baked according to your own recipe.

The device of a home bread maker will remind the masters of a multicooker, there are few fundamental differences. An asynchronous (or synchronous) capacitor motor that runs for a long time while the batch is in progress. It was not possible to make small sizes, in the technical compartment of a home bread machine, the motor takes up the lion's share of the space. The rest is eaten up by electronics. A relay circuit for generating the voltage of a heating element for a home bread machine, working according to the laid down program, guided by the readings of the temperature sensor, and a timer. Electronic models are more common. Mechanical temperature switches are as rare as ticking timers. It is clear - the program is contained in the memory of an electronic circuit, less often it is entered by an advanced user. Do-it-yourself bread maker repair concerns the mechanical part, sensors, control panel. By splitting microcircuits, the master will break his leg, although it is necessary to inspect the capacitors, tracks, resistors.

It's time to discuss the structure of the bread maker. Deprived of the simplest information, the master must avoid proactive actions!

Inside the homemade bread maker is a parallelepiped bowl that prepares the bread. At the bottom there is a kneading paddle. Novice bakers are interested in the location of the blade when a homemade bread maker presents the table with a fresh roll. The paddle folds up. The implementation methods are different, sometimes the motor performs a short reverse. Most washing machines contain collector motors, the speed is transmitted by a gearbox. The paddle of a homemade bread machine is driven by a belt that wraps around a pulley. The collector motor performs reverse by changing the sequence of switching on the windings. The poles begin to attract rather than repel. Switching is carried out by relays. An induction motor changes the direction of rotation of the field inside the stator.This is achieved by correct switching of the windings.

For both types of engines, sudden changes in motion are harmful. The electronic board of the home bread machine that implements the program will suppress speed fluctuations. The temperature is monitored by a sensor. There is a thermistor (thermocouple), the slope of the characteristic is stored in memory. The time intervals of the homemade bread maker are measured by a quartz oscillator, allowing the appliance to know the sequence of actions every second.

The design uses a loop heating element that covers the bowl with a perimeter. The bottom of the working compartment does not touch. Thermal insulation measures will allow you to create an oven environment inside. A homemade bread maker is not a quick fixture. The heating element slowly heats the air inside the compartment, the steel (aluminum) bowl. The non-stick coating prevents the loaf from burning, observing the window of the lid, the chef monitors the phase of the process. The cover keeps heat tightly, thanks to the rubber gasket - even heating of the compartment. The bread is baked, not fried.

A homemade bread maker gives you the ability to adjust the crust color. We believe that the effect is achieved by maintaining the desired baking temperature. The bread will come, the hot oven gives the crust a dark shade. The coating of the bowl is non-stick. Teflon, ceramics, marble - a marketing gimmick, synonymous words. The content of natural material reaches 5-10%. Only a real ceramic bowl will provide a family with safe products (they sell for a multicooker). Teflon, after a couple of years is erased, cannot be restored.

The lid of the advanced models contains a dispenser. A kind of device that allows you to programmatically (according to a timer) fill the dough with nuts, raisins, and other ingredients. The dispenser is operating, controlled by the commands of the microcircuit. The master will check the slamming device if he knows the supplied voltage.

From time to time the paddle starts to swing, gnash, and stops. Homemade bread makers contain a graphite liner. Carbon grease successfully resists heat, is harmless, and is used appropriately. Poses few health risks. A sharp blow the liner is capable of splitting, crumbling, long-term operation wears out the material. Take the time to check the oar regularly. Problems noticed - order a new part. If the bottom of the working compartment is wet with water, the bowl bearings are worn out. Ceramics have a limited life, too thick dough makes the material unusable.

The repair of the bread maker's bucket is limited to the elimination of leaks in the movable joint area. Removing the oar axle, the master unscrews the bottom cover. The screws are scattered randomly, there is a possibility of being inside the working compartment. The pulley is fastened with a nut, there are non-separable joints. The main types of malfunctions are typical:

  • Bread does not bake well:
  1. The heating element has broken. The dough will not rise. Will lie in a lump, the temperature accelerates yeast fermentation, sugar processing. The dough is raw.
  2. Temperature sensor defective. Thermocouple, thermistor. The algorithm of the repairman's actions involves the study of technical documentation. Lack of information forces you to grab a multimeter. The thermocouple gives an EMF (tens of millivolts), the thermistor changes the resistance.
  3. Defective programmer, electronic board. Rarely are mechanical timers-relays (typically microwave oven); servo drive (washing machine). The home bread maker is controlled by electronics - a programmer-executing mechanism in one person. The repair follows a general scheme. The condition of the hinged elements, the tracks of the printed circuit board is assessed.
  • The loaf bears the imprint of an oar, forgot to fold. Reverse relay defective. Broken motor of a homemade bread maker, will not knead the dough. Rarely does the oar mechanism stick.
  • Paddle locked:
  1. The engine is out of order, diagnosed by deathly silence.
  2. The pulley belt came off. The paddle rotates by hand with unusual ease.
  • The oar has to be helped by the hand, starting the rotation.Failure of the home bread machine engine begins. The reason is explained by ill-conceived mechanics. Lack of lubrication, belt problems. Home Bread Maker Warranty - Challenge Customer Service. Until the bakery broke down completely. The problem affects the bowl, the gearbox, a tightly tensioned belt does not do good in any case.

Lack of power is a typical breakdown. You should start with the cord, move up, assessing the performance of the circuit. Electronic stuffing requires a switching power supply. The stabilizer is supplied with a fuse, you should ring the element for integrity. If you find a malfunction, hesitate to install a new one. The fuse alone does not blow. Try switching on a 100W incandescent light bulb instead. If it lights up after turning on the power, quickly unplug the plug from the outlet, look for the malfunction further. An unfavorable mode can ruin the PCB. It is necessary to find the cause of the short circuit of the home bread maker, and then put on the fuse.

In a working power supply unit, the light should not burn at all, it will blink and go out. Continue DIY repair of the bread maker until this condition is met. The simplest power supply includes a capacitor and a rectifier, and this is where the breakdown often lies.

The leading role is assigned to the control panel. The sensor consists of a film on which electrodes are applied. The second half of the PCB assembly on the case. Everyone who looked into the remote control of a TV or other household appliances saw meanders made of copper. If moisture gets inside, unpleasant effects will also occur, however, fatal damage does not occur. The installation needs to be cleaned. The control film is relatively easy to peel off. In this case, it is important not to tear so that the product does not lose its presentation. When cleaning, try not to use an abrasive; it would be ideal to do with acetic acid, alcohol and other reagents to remove oxide film and other dirt.
