Modern washing machines not only make life easier for the owner, they themselves identify possible malfunctions and give advice on how to eliminate them. This is done by the self-testing system; the results of its operation are displayed on the screen in the form of error codes. Among the most common malfunctions, error H20 on the Indesit washing machine stands out. Its code is consonant with the formula of water known from school, which is not surprising. Error H20 just signals that the Indesit machine does not take in water.
Error H20, what does it mean?
Before starting repairs yourself or asking a workshop for help, it’s worth finding out what error H20 means. In a general sense, this message indicates that there are problems with the flow of water into the drum. Essentially, H20 means that during the time allotted by the program, the device did not have time to collect the required amount of water. There are several reasons for this phenomenon.
- The tap that controls the water supply to the Indesit washing machine is closed, or there is simply no water in the water supply.
- The inlet filter, the mesh located in front of the machine valve, is clogged.
- Problems with the mechanical part of the valve.
- The intake valve solenoid coil is burnt out.
- The wiring is damaged, the integrity of the conductors going from the control module to the valve is compromised.
- Incorrect operation of the control module caused by damage to the electronic components of the circuit.
Sometimes error H20 appears not alone, but “in company” with other errors, most often these are: F08 or F01. In this situation, H20 is not a malfunction, but only its consequence. To correct the situation, it is necessary to eliminate the causes of other errors in the Indesit washing machine; most likely it will go away along with them.
Having figured out what the H20 error code means, you can move on to correcting the situation. There seem to be two options for solving the issue: you can call a technician, or you can try to repair the Indesit washing equipment yourself. Whatever path you choose, before taking decisive measures to eliminate the H20 error, it is worth performing a few basic operations, namely, checking whether the water is suitable for the device.
What if everything is simple?
According to statistics, in the vast majority of cases, error H20 on the display of an Indesit washing machine has nothing to do with the failure of components or assemblies. The main reason for its appearance is the banal lack of water in the water supply.
That’s right, before calling a technician or disassembling the Indesit machine in search of a broken part that caused the H20 error, you should make sure there is water in the system and its pressure is sufficient. If there is no water at all or the pressure is too weak, simply postpone the wash until the water supply parameters normalize.
The same effect is achieved by a faucet that is closed due to forgetfulness or is broken, cutting off the water supply to the device. Everything is also simple here, to eliminate error H20 you just need to provide a water supply and restart the washing program. Most likely, the H20 error will disappear.
DIY washing mashine repair
The Indesit automatic washing machine is a complex device; its repair will require special skills and abilities. This is true, but if you have the proper knowledge and experience, you can try to eliminate the cause of the H20 error yourself. This will allow you to save a lot, the main thing is to soberly assess your strengths. You need to know how to disassemble an Indesit machine, how to assemble it, how to fix a damaged unit.
Water supply system is clogged
If there is water in the system, the pressure is sufficient, the tap is open, but error H20 does not disappear and water does not flow into the tank of the Indesit washing equipment, it is worth checking the inlet hose and the inlet filter mesh. To do this you need to do the following:
- turn off the Indesit machine, turn off the water supply;
- unscrew the hose and rinse it thoroughly;
- remove and wash the filter mesh.
In addition, you should inspect the hose for kinks; it often happens that, trying to rationally use the modest space of the bathroom, the Indesit machine is pressed against the wall. This may be the cause of error H20, because the hose is bent, thereby creating an obstacle to the free flow of water. If there is a kink, the hose will most likely need to be replaced.
Problems with the filling valve
After the hose and mesh of the Indesit equipment have been washed, it makes sense to repeat the washing program. If water still does not flow, the culprit for the H20 error may be the valve that regulates the water supply to the device. Structurally, it consists of two parts: mechanical (solenoid) and electrical. To resolve error H20, you need to check each of them.
- Checking the filling valve involves partial disassembly of the Indesit machine, therefore it must be de-energized before starting work. The water is also turned off.For ease of work, it is advisable to move the Indesit machine to the middle of the room, providing yourself with space and lighting.
- To access the valve, simply remove the top cover of the Indesit machine. Next, the valve is unscrewed and all fittings suitable for it are removed.
- The valve of the Indesit washing equipment is thoroughly washed. In case of constant use of low-quality water, salts may be deposited on the walls, interfering with the normal operation of the device. It is worth carefully inspecting the mechanism and cleaning it if necessary.
- The electrical component of the valve is checked - the solenoid. The device for checking it is a multimeter. Using a switch, it is switched to resistance measurement mode. The resistance of the working coil should be approximately 3 kOhm. If the device shows a break, the valve will have to be changed to eliminate error H20.
The Indesit filling valve is highly reliable and designed for long-term operation, however, it can fail and lead to error H20. The main reason for this is voltage fluctuations. To avoid such malfunctions and ensure a longer service life of the Indesit washing machine, it is recommended to connect the device through a voltage stabilizer.
Replacing a failed valve will not cause any difficulties; you just need to buy a device of the same model and install it in place of the burnt one. It is important to choose a good seller; you should only buy an original valve, this will guarantee no problems in the future.
Control module malfunction
The source of the H20 error can also be the Indesit machine control board. Its diagnosis and repair are difficult, so before removing the board you should make sure that other faults are excluded.
Before disassembling the Indesit washing machine module, it is worth ringing the conductors going from the board to the filling valve. Make sure there is no oxide on the contact pads, at the junction of the conductors. If necessary, the conductors are changed and the contacts are cleaned.
After removing the Indesit unit module, you should carefully inspect the electronic components of the circuit. Often the fault can be determined by eye. These are blackened or physically destroyed resistors, swollen capacitors, and oxide deposits on the board. If all the parts of the Indesit machine look like new, no external damage is visible, then to find the cause of the H20 error, you need to look for the device diagram and scrupulously call each element and the connecting tracks between them.
Call the master
Repairing an Indesit machine yourself requires knowledge and skills, and also time. Those who do not have experience working with components of electrical circuits and do not want to understand the structure of the machine can be advised to call a specialist at home or take the washing mashine to a workshop. Specialists will quickly detect the malfunction, decide what to do and carry out all the necessary work.
The same advice can be given to owners of an Indesit machine whose warranty period has not yet expired. Do not try to disassemble the warranty device. A washing mashine with signs of disassembly can only be repaired at your own expense.
Error H20 on the Indesit washing machine indicator is not a signal of a critical breakdown; you can find its cause and fix it yourself; you just need desire, experience and perseverance. But as a result, you will be able to save not only money, but also time, because the washing mashine will be ready in a couple of hours.
