The Weissgauff PM does not take in water after heating. ⇐ Other manufacturers

[Nikolay90]

Direct your thoughts, if possible, in which direction to look for the breakdown?

Dishwasher Weissgauff DW 4012 starts to work properly, but after about an hour of operation, in a heated state, it suddenly shows a squeaking error - icon "rinse" (according to the instructions - this icon also means an error code: lack of pressure in the water supply system or a faulty filling valve). But the pressure in the system is fine.

After draining the water manually, and after turning it off and on, the machine still shows this error. But having cooled down a little, it allows you to start a new cycle, the water is poured into it perfectly.

The error appeared at first after 2-3 washes, now it’s constant.

It develops the impression is that the filling valve or electronics are failing due to heat or steam. Does this happen, or is it something more complicated?

Regards.

The problem may be a faulty fill valve or drain pump. A malfunction of the pressure sensor in the water supply system may also be the cause. It is necessary to check these elements and, if necessary, replace them. It is also worth checking the condition of the dishwasher’s control electronics.
