Thanks to previous posts I was able to replace triple water valve on this machine. Symptom was displayed E10 code and failure of dryer to work due to open circuit solenoid on one part of water valve that allows water to flow to condensor. Got slightly stuck trying to remove small piece fitted between water valve and rear of cabinet. I was sure this piece should unscrew from the water valve but couldn't understand how it could having a thin square shoulder that would appear to interfere with square end near the end of the valve. It was tight but the thin shoulder was simply soft enough to move aside to allow the piece to unscrew using brute force and ignorance. The posts also were detailed enough to allow me to split the machine to gain access to and remove some fluff from the condensor. Thanks everyone.
