Cliff for Model Number Bosch SHE44C05UC/40 Two weeks ago, the dishwasher started taking a really long time to complete a cycle. Then last weekend, it stopped draining at all. Based on user forums and the fact that the drain pump had been quite noisy for some time, I assumed (often a mistake) that it was the pump. So I ordered and replaced the pump. Here's where it gets tricky. Upon starting the dishwasher after pump replacement, I heard an audible pop near the control board. The dishwasher then preceded to run through a short rinse/hold cycle, but again failed to drain. I have tested continuity of the drain pump and the lines to the pump - both tested positively for continuity. I have also tried resetting and running diagnostics, after which a I received a C1/PO error code followed by an E1 code. I have read several forums that state the E1 code indicates a problem with the heating stage (which would lead to prolonged wash times) and that the issue is likely an overloaded 10A relay switch on the board. That may be the case, but what do you make of the failure to drain and the pop I heard? I have no problem with replacing the control panel, other than the fact that Bosch apparently installed relay switches that are way too close to max load. However, I don't want to spend another $130 + if that's not the issue. Thanks in advance for your input.
Answer Hello Cliff. Test for power to the pump. If it is not there, you will need to replace the control board. You can test this with a multi-meter TJMA-DMT3. Here is a link on how to use a multi-meter. http://forum.appliancepartspros.com/oven-repair-including-ranges-cooktops/4810-how-check-continuity-ohmmeter.html Read More...
