So, obviously from the title, my whirlpool washer is throwing the above error codes. This one has me a bit stumped on what to do next. From my research, I know these codes are most likely a comm problem between the MCU and the CCU. I've pulled the MCU and visually inspected it. It looks fine. No burned traces or such. The plastic cover is slightly discolored above the biggest chip on the board, apparently from heat, but the board looks fine. I pulled and reseated all the connectors between the MCU and CCU. They all seem tight.
My biggest problem is this particular washer doesn't seem to match anything I can find online for it. It seems slightly different from all the videos and such that are supposed to match it. For instance, everything shows a lower front access panel. This unit has an all one piece front panel that can't be removed without taking the boot seal loose, etc. I got into it from the back panel. None of the connectors to the MCU match descriptions or videos either. I realize that there are many models very similar with slight differences, but it makes the troubleshooting tough. I did check the reading with my meter across the pins going to the motor from the MCU and I get 9 ohms, which doesn't match anything I've found online, but I have no idea if it's indicating a problem with the motor.
I suspecting the next step is to replace the MCU, but given the price of these parts, I wondering if there is additional troubleshooting I can do that would help pinpoint where the problem is?
We did take a fairly close lightning strike a few days ago and everything in the house flickered. We then discovered our microwave has died also. I'm guessing that that is likely the cause of the washer problems too, but not sure what to check or replace next.
Any pointers greatly appreciated! Thanks.
