i have changed pumps and control panel over the years with no problem. this time my control panel was displaying broken numbering and i was still able to use except i had to unplug after use i operated many times . then today i plugged it in and no power at all. i had an extra control panel replaced old one with new and still no power .what do you think is the solution? it is an lg tromm washer dryer combo.model wm3677hw
