Mike G for Model Number Bosch WFMC3301UC/09 - Pump 00436440 - Code E04 We have opened the cover to the drain pump many times and there has been no debris. On rare occasions there might be a tiny bit of lint about the size of an ant. I have also disconnected all the drain lines and made sure there was no debris or blockage by blowing in them. We still keep getting the E04 code and no draining about every 15-20 loads. I was looking at the drain pump impeller. Is there supposed to be any side play/movement? Mine seems loose. I am ordering a new drain pump, but was wondering if I am missing anything or am I correct in replacing the pump? Thank you!
Answer Hello Mike. It sounds like the pump may be failing and need to be replaced on the unit. It sounds like your on the right track. Read More... Answered by AppliancePartsPros.com | Thursday, July 23, 2015
