LG/Kenmore washer dead, wiggled wires, then alive - am I done?
« on: January 11, 2015, 11:40:23 AM »

Hi - This Kenmore (by LG) washer worked great and is well maintained.  Today it ran a load and then when we tried to run a second load and it was completely dead.A/C power was fine.  Based on what I read online I opened it, disconnected the output of the line filter (first place A/C power goes inside) and tested the output of the line filter with a Multitester.  It looked good.  So I re-connected the connector, and even though it was unplugged, the water pump ran briefly, so I plugged it back into A/C and it came back to life.

Am I done?  Should I replace the line filter?  Any/all thoughts welcome - thanks!

Probably the main.  When it fails,  see if you have power out of filter.

As I noted, the A/C power to the washer was fine, as was the power out of the line filter.

My theory is that the electronics needed to be power-cycled, but the line-filter was maintaining a low-voltage, so disconnecting the line filter output from the washer reset the electronics.

 thoughts?  thanks!

Thanks Domain.  but are you saying the power-cycle fixed it - or I have to order a new board?

I would run it. If the problem returns, replace the main pcb.
