Munn P for Model Number Bosch SHU5313UC/U12 The dishwasher is not draining at anytime during the cycle. The drain line and internal air gap are clear and as far as I can tell the line from the bottom of the tub/pump impeller are clear as well. I removed the filter screens and drain pump impeller cover, also clear. The impeller turns with the sort of stepped resistance you would expect from a direct drive electric motor. The dishwasher will run through a regular cycle or a wash and hold cycle. Other cycles are not selectable nor is cancel and drain. Could these all be symptoms of a failing control board? Are there other components that could fail and prevent it from draining? Could it still be the drain pump? Thanks, Munn
Answer Munn, The first thing to check would be to make sure that the dishwasher controller is sending power to the drain pump when it calls for draining. If it is not then the issue would be the control module. If it does then the drain motor would most likely issue. Read More... Answered by AppliancePartsPros.com | Friday, April 18, 2014
