My drain pump keep running when I start the dishwasher and even when I open the door. No runner come in. I cleaned out the drain and clean the pump wheel. Still the same. I did the test Bosch told me to do and what come up is PO and C1. Is this telling me the pump is bad or what do you think?. Bosch don't tell me anywhere what these mean.
ANSWER Hello Wally. Look for a leak in the base of the dishwasher and repair the leak. It causes the pump to come on to prevent flooding.
