hi trying to find help with a lg washer model wm2277hw it will not drain gives oe code checked all drains and both pumps all are good even removed the pumps cleaned and tested them on the bench both run great. re-installed ran through 1 cycle ok then again with the oe code. called repair guy he came out same thing with one exception when he tested the leads to the drain pump they are only register at 94-97volts so i checked the outlet it is fine 120v. so my question is do i replace the mother board? is it possibly sending a wrong signal to the drain pump? or would i go with replacing the the drain pump even though it ran great independently?

I have same issue, how did you fix it?
