Hotpoint HIO 3C23 WF error 15 ⇐ Hotpoint-Ariston

[Newbie]

Hello!
Dishwasher Hotpoint HIO 3C23 WF. Error 15. The error does not appear immediately. The machine starts the cycle, draws water, starts washing dishes, but stops with error 15. The heating element is working (checked for breaks and leaks). The wires to the heating element were also checked. On the board "brains" no no visible damage, swollen capacitors, traces of water, signs of oxidation or corrosion. I haven’t been able to find a service manual for this machine yet.
Sometimes it doesn’t fill up with water at all, but an error occurs even those times when it does fill up.

Newbie, how did you decide? The same situation.

The problem is solved by replacing the graphite bushings on the circulation pump. The pump itself is expensive and the craftsmen charge a lot for this work. Although everything changes there simply. Find craftsmen on Avito who print bushings and impellers on 3D printers. Contact them and send me the markings of your pump. It is best to order it together with the impeller, as it is faster to break it and replace it with a new one.
