Narasimha K Bloomfield Hills , MI July 27, 2016 Appliance: Whirlpool Washer WTW6800WW1 Whirlpool Washer Wtw6800ww1: F2 code "user interface mismatch" machine keeps beeping and frozen permanently. How to replace Electronic Control Board. Ordered the replacement panel from APP. Went in perfectly, matched the model, and machine back to perfect working order. This is the 2nd panel I am replacing in this 7 year old m/c, one of the numerous switches on the board goes bad/shorts out? and causes the panel to throw an error code. Looks like some design flaws on the panel. Hope this lasts longer :7( May have to replace the machine the next time this goes again!! Best part in this bad experience was the ease of finding/ordering the right replacement part and promptness of delivery by APP! Best price on the net too! Thanks again! 1 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 15-30 minutes
