wfw8500sr0 Whirlpool error code f-28

The new MCU did the trick. The washer is working! My thanks to Repair-man and JWWebster for their help.

Here are some pics of the old MCU showing some electrical damage. From now on all my expensive electrical components will be used with decent quality surge suppression, etc. I mean, these things are as expensive as a HDTV, might as well give them appropriate protection.
