Indesit washing machine - Error H20

Error H20 in the washing machine Indesit usually makes itself felt at the moment when the program is just starting to draw water into the tank. Water murmurs for a long time, and the drum spins up for about 5-7 minutes, then the washing machine hangs tightly, and the code H20 is displayed. Our task is to decipher this error, determine the causes of its occurrence and indicate the most acceptable ways to eliminate these causes.

What could have happened?

In 90% of cases, the reasons why the H20 error occurred are more than commonplace and are not at all associated with any malfunction. Even if we discard completely clinical cases when a user calls a service center complaining of a H20 error, and he himself does not even guess to check if there is water in the water supply, the reasons are quite ordinary.

By the way! According to statistics provided by leading service centers, every 9 customers calling for problems with the H20 error did not check if there is water in the water supply.

Before we get down to discussing them, let's decode the error code H20. The transcript looks something like this: "the washing machine cannot get water for a certain time." Why are there problems with water intake?

1. Forgot to open the tap located at the junction of the inlet hose and the water pipe.
2. The strainer filter in front of the valve of the Indesit washing machine is clogged.
3. The mechanical part of the filling valve of the washing machine is damaged or clogged.
4. The electrical part of the filling valve burned out.
5. The wires supplying the filling valve are burnt, oxidized or broken.
6. Communication between the control module and the filling valve is broken due to problems with the electronic control board.

Water Ingestion Issues

Error H20 completely paralyzes your Indesit washing machine, preventing it from washing, rinsing and wringing things. All this can happen due to problems with the flow of water from the water supply. Imagine that the taps are all open, there is water in the water supply, but for some reason it does not get into the washing machine. Before thinking about the malfunctions of certain components of the washer, we will see if there is a blockage on the way from the water supply to the machine’s tank. We do the following:

• close the water;
• unscrew the water inlet hose into the washing machine;
• clean and wash it properly;
• at the base of the machine, in the place where the inlet hose is screwed, there is a wire mesh, it must be removed and washed.

If the problem persists afterwards, the inside of the filling valve must also be cleaned. To do this, first disconnect the washer from the mains, then remove the top cover of our machine. After this, we unscrew the filling valve, pull out all the pipes that fit it and remove it to the side. Next, we disassemble the valve body and rinse it thoroughly.

Damage to the filling valve

If you disassemble the filling valve, you see that the problem is not at all a blockage, but the opening and closing mechanism, and it does not work well. So you need to find out the reason why this happens. Inspect and feel carefully the mechanism of the filling valve and try to understand why it does not work. Take a multimeter and measure the resistance of the contacts.

The resistance of the working inlet valve is about 3 kΩ.

The filling valves of Indesit washing machines do not break very often. The main reason the valve burns is because of voltage drops. That is why our masters strongly recommend connecting the washer through a voltage regulator, especially in cases where the power supply is unstable.

Blubber control module

Error H20 may appear due to the control module, but to make sure of this, you will first have to exclude all of the above reasons and only then you can most likely blame the electronic "brain" of the washing machine. Checking and repairing an electronic module is not a simple matter, even for those who have experience working with various kinds of microcircuits.

After removing the electronic module, carefully inspect the control board, some breakdowns can be identified visually. Burnt paths, triacs, thyristors and other elements can be noticeable if the module has undergone a voltage drop. In all other cases, the defect can only be determined in the process of scrupulous ringing of the circuit.

We are not opposed to the independent repair of the washing machine, however, we are of the opinion that not all malfunctions can be fixed at home with your own hands. Sometimes you need to trust a professional. Damage to the control module is just such a case.

To summarize, we note that faced with the H20 error on the Indesit washing machine, do not rush to panic, most likely you will be able to eliminate the cause in a short time. True, it happens that this error pops up due to a breakdown of the control module, but such cases are rare, you can not be especially afraid. Good luck
