 Hansa ZWM 627 IH stops washing and switches to different modes

Post by mahanka »

Good afternoon!
Dishwasher: Hansa ZWM 627 IH
I encountered the following problem: the machine washed soap on a 2-hour cycle. After about 15 minutes it beeped and stopped washing. And after a while I started going through modes (it looked like these were test modes), at the end of which there was an F1 error. The machine does not respond to any buttons.
After turning it off and on - the same picture. I recorded a video of what it looks like after switching off:


Called the master. He came, tried different modes (it took about 2 hours), but the problem did not recur. Those. There were no problems at all: the machine takes in water, heats it and drains it.
The next day I installed the machine. It worked for about 15 minutes, beeped, after some time reset the selected mode to the initial position (as if I had just selected this mode), and started washing. About 5 minutes later - the same thing: it beeped, reset the mode to the initial position and started erasing.

Has anyone encountered similar behavior? Or can you tell me where to look?
Thank you!

Exactly, it was a matter of oxidation on the buttons. Where there are contacts, everything is fine. And from the side of the buttons themselves, it turned sour. The technician replaced all 4 buttons. They served for 6 years, I hope the new ones will last at least as long :)
