4.5 years old (12/2013) Top loader HE.
No lights, nothing. Just hear relay click on/off once when plugged in or start button pressed. LED on main board is NOT lit. There's a resistor (elevated off board) that gets hot and smokes a bit like a soldering iron. So there's power getting to the main board, I also verified power in an out the filter. There's power on either side of the tubular fuse mounted on the main board.
History of problem.
Washer was filling for a load, while I was in the laundry room. Phone rang, so I paused machine so as to hear better. Got involved with call. Machine started to empty water on it's own (default action I have read). Just then house power went off. Came back on few moments later (brownout, not a power surge) no other electronics in house affected. Washer cycle was manually restarted, was filling but water also flowing out discharge hose but not being pumped. Like water was siphoning slowly. Turned OFF washer. Water still siphoning out. So I changed to SPIN ONLY, figuring to reset the problem. That worked fine, started a new wash cycle with EXTRA RINSE. Water filled fine, was not siphoning out. Seemed fine, washed clothes, rinsed first cycle. Was on the last RINSE cycle with 15 minutes left. Machine froze with display panel lit, showing rinse cycle and 15 minutes left. No buttons worked, tried the PLAY/PAUSE and the ON/OFF. Nothing. Water was NOT coming out the discharge hose. I unplugged machine, waited a bit and plugged back in. Just heard click-click. No lights, nothing.
Opened up machine to see main board. LED not lit. Checked the filter voltage in & out. Noted voltage on both sides off aforementioned fuse on main board. Discovered very hot fuse, which gives off wisps of smoke.
Manually scooped out water but there's still some in there. Drum spins freely.
Do whats next? Arrow shows resistor that gets VERY hot.
Anyone have diagnostics manual or link to same?
