WFW9150WW00 DUET All steps for F8E1 error code completed, as per manual. At NORMAL startup, water enters fabric softener side. Not soap side. After cold water stops, how water valve continues open with a trickle and washer drum begins cycle. Valve turns off after 2 -3 minutes as washer continues. Washer stops with F8E1 code. When on RINSE mode, cold water runs through soap dish side, and overfills drum. I'm thinking the CCU is wonky, but I've read that the MCU may cause anomalies and I really need to isolate the issue. Regards and thanks.

The water level pressure sensor is bad and needs to be replaced the sensor you need for the model you listed in linked below.
