There is a large list of error codes, standing for different small and big issues, for washers of various manufacturers, including Bosch, some are rare and serious, others are more widespread and easily fixed, just like the water supply failure, which is usually reflected by the E29 code on the device’s screen. This code shows you that not everything is ok with the water detector or intake system of your appliance.
What can provoke the E29 error?
Generally, this code demonstrates that the sensor doesn’t detect the water fill of the unit, or does it too slow. So, first of all, it is necessary to inspect the parts, the supply of the water to your appliance depends on. Commence with the hosepipe. It may be plugged or simply whirled, which blocks the water from reaching the tank. Another significant thing about the hose — it has to be not lower than 50cm above the ground, as this is where the tank is located.
Besides the hose, the filter, located between it and the valve, which can also be clogged with dust and dirt. The impurities simply do not let the water in.
Another aspect you can easily scan is the water pressure — divide the hose and put it into a sink to see how water goes out of it. If you notice that flow is weak and slow, turn the inlet valve.
The issues with the water sensor can be the reason for the E29 error too. Though it is a really rare thing, you’d better examine it as well.
One more unusual probability is the breakage in the AquaStop system of your High-Efficiency washer, which is not usually indicated by E29 code, but still can happen.
How to resolve the E29 error?
After you checked the water supply elements of the washer and the water-pressure in it, you can examine the filter. You only need to remove the hose and take the mesh out. Rinse it thoroughly and install it back. If the error is still on the display, let’s have a look at the pressure switch.
To check the sensor, you have to pull off the upper board, and under it, you will see a rounded mechanism, connected to other parts with the wires, there is also a thin pipe, which you have to detach and to shift again, slightly tapping on it. After everything is back in its places, close the panel and restart the washing process.
If none of the above methods worked and the E29 error code is still indicated on the control panel of your appliance, there might probably be a more serious issue. For instance, with the inlet valve. In this case, you’d better contact the specialist.
