Product review (5 stars): Repairs Sud/F35 Error on Whirlpool Duet Washer
We have a Whirlpool duet washer model no. WFW9500TW01 and kept getting the Sud error, followed by the F35 error.  I watched the youtube video, ran the diagnostic (which failed) so I ordered this part.  Following the youtube instructions, I replaced this analog pressure sensor in about 5 minutes.  It takes longer to unscrew the top panel of the washer than it does to make the repair, which requires swapping out the connection hose and wiring harness plug from the old APS to the new one.  This was a super easy repair.  I will also follow the youtube instructions and use only 2 tablespoons of detergent from now on.  Whirlpool says to follow the detergent manufacturer's instructions, but clearly that is not correct.
