LG Front-Load TROMM Washer (WM2077CW) DE/PF Error
I started getting DE (Door Error) and then PF (Power failure) errors on this relatively new washer. The errors seem to come up together. Sometimes a DE, followed by a PF, or maybe a repetitive PF. I checked all connections and wiring harnesses for loose or chaffing connections. Nothing. Finally took a chance and replaced the door lock sensor/mechanism, but to no avail.
Is the control board the next likely suspect and/or the powerline noise filter? Should I try and replace the filter first (cheaper) or the controller or should I do both? Any other troubleshooting ideas?
