Bosch Dishwasher SHE44C02UC /22 won't drain during wash cycles

4 posts in this topic

Good morning all. This problem first surfaced in October of last year. I wasn't able to solve it then and the dishwasher sat. Now, with the new year and an inability to replace this appliance I am once again trying to diagnose, then fix this dishwasher.

I checked out the controle module for a burned solder trace for the water heater and the board is clean, so I put it back. Oh, yes. Before checking the controle module I ran the self diagnostic.

The washer does the initial drain and indeed when the test was finished all but the last few ounces of water were gone from the sump.

BUT, this dishwasher will not complete a real life wash cycle.

The self test finished with an "E 1" which my researches on the web indicated (I think) that there was a heater problem. I haven't checked the resistance of the heater unit yet. I guess that is next.

What advice can anyone give me on this? If nothing else, I may just up and replace the heater unit and keep my fingers crossed.

Regards

Confused ??? in the title you say won't pump, but then say it will pump - what are the symptoms of the machine ?

You can't just measure that heater for resistance, the machine has to be full/running before circuit is made - can be done live (carefully) - failed controller does not ALWAYS show burnt relay connections.

Confused, no I don't think so. By the initial drain I meant when you first start up the dishwasher cycle it drains if there is any water and then fills appropriately for the first wash cycle.

However, is it possible for the heater relay to stick from time to time but not always?

Is there a way to check to see if the controller is not working or is in a failed state? When I entered the diagnostic program it seemed to work through the various program stages.

Can a controller fail partially? I am willing to try and check this out if there is a way.

Thank you for your reply and help.
