Replacement of the membrane of the water unit of the gas column Neva 4510, Neva 4511, Neva 4513, Neva 4011

AND So! Let's start with the simplest. (The topic is relevant for all gas water heaters).

The weakest point in any gas column is the membrane. Why? Because in 99% of cases the following happens.

You turned on the tap, but the column does not start. The first and most likely reason is that the membrane has burst.
You turned on the tap, and the column does not give the flame at full power. The flame is "small" and the water heats up poorly. This is because insufficient gas is being supplied to the burner. The diaphragm does not push the stem with the force required to open it completely. The first and most likely reason is t thickness in membrane .
You turned on the tap, and the column is unstable. It often turns off or only turns on from the third or fifth time. The first and most likely reason is Rmembrane stretched from time to time .

Therefore, before raising a panic, you should always start by replacing the membrane. In general, we recommend simply changing the membrane every two years, without waiting for the above troubles. What's the matter?

The membrane is the most basic element during normal column start-up. Why? When the tap is opened, the water flow creates a vacuum behind the membrane, the membrane bends. That, in turn, shifts the stem, which opens the gas supply to the burner, and all this works purely mechanically, which means it is subject to wear.

The price of the issue. The cost of a membrane for any gas water heater is from 200 rubles. up to RUB 500 We buy a membrane. When we have a brand new membrane in our hands, to replace it we need: a pair of screwdrivers, 8 mm and 24 mm open-end adjustable wrenches, a glass (only for professional plumbers) and 30 minutes of time.

In order for your eyes not to run, first look directly at the photo of the NEVA 4511 column with a water-gas unit installed inside. Screws and nuts are marked with red dots, which must be unscrewed to separate the water part and then work with it. When the eyes are more or less accustomed, we move on to the first point.

1. Before us is a water-gas unit used in gas water heaters NEVA 4510, NEVA 4511, NEVA 4513. Between themselves, these units have a tiny difference, but this will not interfere with the matter. First, a couple of points to understand what it is. It consists of two halves: a gas unit (this part is gray) and a water unit (this part is yellow). We take a “plus” (Phillips) screwdriver and separate the gray part from the yellow one.

2. The third photo shows how they are fastened together: with the help of two screws, simply squeezing from the ends this “grease cylinder” of the water unit. Let's consider the water part. Photo 4. Here, where the grease is, do you see a hole on the end of the cylinder? It is from this hole that the stem comes out, which opens up gas access to the column. It is it (the stem) that our membrane pushes when opening the tap.

3. To get to the membrane, carefully unscrew all six screws and the water assembly will open in half, like an oyster.

4. If you carefully examine both the resulting halves, it is easy to guess that the membrane is this black elastic band lying in the right half. The membrane, as you can see, has an eyelet that fixes its position. Carefully remove the membrane from its containing halves.

5. And what are these parts inside? One of them is a plate with a stem, the second is a spring. Our membrane presses on this plate with the stem. The spring, on the other hand, returns the stem to its previous position when the valve is closed, gas access is stopped and the column is turned off. If everything inside our oyster is dirty, take out the plate, take out the spring.

6. Everything inside this yellow saucer is thoroughly cleaned and washed. We replace the membrane with a new one.Do not forget about the membrane eyelet, which fixes the position correctly. Don't forget about the sides of the membrane. She should, as it were, hug the plate with the stock with her recess. Then everything will work correctly.

Now we scroll everything in the opposite direction (both pictures and screws). We open the tap. And finally, we wash. Section Membranes.

Warning. This section is intended for specialists who have the appropriate permission to repair gas equipment! If you repair yourself during the warranty period, the warranty is void!

This article will focus on malfunctions of Neva speakers (models 4510, 4511, 4513, 4510M, 4513M, 4610, 5611). Many Chinese speakers, such as Vecktor or Oasis, and not only Chinese ones, work on the same principle as the Neva, so the remedies below apply to them as well. But, please be more careful, the photographs in the article show details for the Neva columns.

No spark when hot water is opened.

When the hot water tap is opened, there is a spark discharge, but the column does not ignite.

  1. Check if the hot water tap in front of the column is open.
  2. There is no gas in the main gas pipeline. You need to call the service to fix the problem.
  3. Check the serviceability of the EMC. Image - DIY repair of a geyser neva deluxe 4513Connection contacts may be broken.
  4. Correct the spark plug, it is possible that the discharge does not reach the flow of the gas-air mixture (about 5 mm from the end of the plug to the burner).Image - DIY repair of a geyser neva deluxe 4513
  5. When using a column from liquefied gas, it is necessary to check the gas supply in the container (cylinder).
  6. Weak spark from spark plug electrode. It is required to clean the contacts of the battery compartment or to completely replace the ignition elements (batteries).

The column will run for a while and turn off.

  1. Poor cravings. Thrust sensor triggering. Image - DIY repair of a geyser neva deluxe 4513It is necessary to clean the chimney or check the tightness of the exhaust pipe connection on the column pipe.
  2. Overheating of water (outlet water temperature is more than 90C, triggering of the limit temperature sensor). It is necessary to use the column control knobs to reduce the gas consumption and increase the water pressure.
  3. Replace the membrane of the water unit.Image - DIY repair of a geyser neva deluxe 4513
  4. There is no signal from the ionization sensor (flame sensor). Image - DIY repair of a geyser neva deluxe 4513In this case, the burner works for no more than 7 seconds, and spark discharges from the spark plug do not stop. It is necessary to restore contact with the sensor, correct its position (if it touches other elements of the burner) or replace it.

The water temperature reading is not shown on the column display.

  1. Defective water temperature sensor. It needs to be replaced.Image - DIY repair of a geyser neva deluxe 4513
  2. Check the connection contacts of the display itself to the ignition unit. If there is no result, replace the display.

The water does not heat up well.

  1. Reduce water pressure.
  2. It is required to check the heat exchanger for the presence of scale on its walls. If necessary, remove it, rinse with Solita.

  3. Insufficient gas pressure in the line - call the service to eliminate the causes.
  4. Repair or replacement of the water unit is required. Image - DIY repair of a geyser neva deluxe 4513

The flame of the burner of the column is yellow and weak, with smoky tongues.
