Problem with Hjälpsam dishwasher

I also have a problem with the Hjälpsam dishwasher. One day it also stopped with the well-known "three beeps" and only pumped out water, although it hadn't produced any foam, etc.

After reading the posts here (thanks ), I emptied the sump and ran two dishwasher cleaners through it. That worked fine for two wash cycles, and then the sump was full again... Usually when the machine had been "resting" for a while. You can't say at what point in the program, sometimes after 10 minutes, sometimes after 50 minutes, it varies a lot.

The water then runs through the two thin black hoses into the sump, but I simply can't determine where the hoses come from, at least not without pulling out the machine completely and removing the side panels.

Since the machine is still under warranty, I'd rather not remove any covers except for the sump plate.

Where could the problem be coming from?

If there is still a warranty on it: hands off and call customer service.

And then post the answer here for those who no longer have a warranty.

So the Electrolux service was just here. The following kit was installed: "GLOBAL HYDRAULICS: PRESSURE SENSOR MODIFICATION" with the item no. 405 534 606/0 Only the air trap "a" and the gasket "c1" (two out of five parts) were installed. But I was allowed to keep the rest. I'm curious if it helps, I still have 3 1/2 years warranty. The error is apparently known.

Thank you for the feedback.

And, did it actually help? I have the same problem as you back then! Can you tell me if both parts were only installed from the outside or did the dishwasher have to be removed????
