Anthony C for Model Number wfcm6400uc I have a Bosch washer Nexxt WFCM6400UC. I have just received and installed the replacement drain pump that was provided by your company. it was a bit different than the original, a bit lighter and it contained a manual drain. it was installed from the rear. Although a bit difficult it was easier than taking apart the front cover. Once all the work was complete the water was tuned on and the machine was plugged in. The water fill was filling the machine and the drain was activating at the same time. The machine would start to aggregate at a slow speed.the water would pulse and fill intermittently and when ever the machine took water the pump would drain it out. After about 8 minutes a error code would appear " water tap closed". the tap was open and clear, the filterers were clear, Why would the machine fill and drain simultaneously. Please help it doesn't seem as if it is a siphon problem as indicated on some blog sites.
Answer Hello Anthony. You either have a siphoning issue, or the board is powering the pump when it is not suppose to and you will need to replace the board on the unit. Read More... Answered by AppliancePartsPros.com | Monday, March 10, 2014
