Our washing machine inlet valve leaked, allowing water to pool below a circuit mother board. This caused something to happen which produced black soot to cover the board.
A $300.00 part. I understand I might have a chance cleaning it up. I need to anyway to possibly find the incapacitated resistor / diode / whatever.

Thanks. I already have a brand new bottle of 91% Isopropyl Alcohol. Also a can of Electra Clean ( CRC brand, for electric motors and equipment ). I wanted to pre-wash it.

Yup. Use HOT water (so it evaporates quickly) and a gentle tooth-brush. Forget the soap, it will leave a residue that can short the board. Shake it well and let it air-dry for a couple of days before using it.
It was a pretty standard way to save the control boards in slush and popcorn machines when they get too gummed up from syrup and oil, and at $600+ a pop it was wprth a try to save them. Worked sometimes, sometimes didnt (they had already shorted from the crap)
I still use the method to wash out my keyboards and mice every so often.

Check for a recall - ours leaked and caused a TON of damage. Kitchen floor and basement ceiling. messy and expensive situation... *casually pukes in a bucket*
BUT... There was an issue with the material used to construct the valves in a buttload of washing machines (I think its Nylon?) it erodes over time and the diameter changes and causes a leak, even if you replace the hoses every few years... so we got back a little $. Emphasis on "a little"
But yeah, you can, I recall folks used to clean their boards in a washing machine back in the day. But that's back when capacitors were as big as a hot dog, donchaknow...

Yes you can, once 
You want to be carful about the soap you use, some soap can damage the board.
I would suggest removing the board, making sure everything has been discharged and then rinsing as much as you can with distilled water.
Then a good cleaning with the alcohol and CRC cleaner.

Wow ! They sure have a lot of recalls. Thanks. Most are for front loaders but I see others.
I see that they had a ten year warranty, listed as five for labor.
The wife unit says we are buying Speed Queen, new.

New is junk, go find a repair place and buy a refurbished used one.

Cliff- If you use alcohol make sure you allow the circuit board to completely dry BEFORE you hook it back up to power.....(Alcohol and sparks don't mix!)
I'll shut up now........

What Jake said. New Speed Queen is no better than anything else today. [This message has been edited by Lambo nut (edited 05-18-2021).]
