David for Model Number WFW9500TW01 Whirlpool Duet Washer, model no. WFW9500TW01. Water is flowing into tub but receive F-20 code approximately two minutes into cycle. Suspect flow meter. Pressure switch was replaced less than a year ago and pressure hose, drain lines, etc. are clear. No siphoning problem. Screens at inlet valve are clean. Could inlet valve still be the culprit if water is flowing and there are no leaks?
Answer Hello David. It does not sound like the valve. It sounds like the flow meter WPW10110225 or the pressure switch WPW10415587. Read More... Answered by AppliancePartsPros.com | Tuesday, October 7, 2014
