I just replaced the latch on the washing machine. It worked fine for the first wash, then it started showing code f21 and now f28 and the door won't open.
ANSWER Hello Eglien,
Error f-21 means not enough water entering tub within the first 10 seconds of the fill cycle. Check you water faucets to insure they are turned all of the way on. If they are, the water inlet valve 8540751 is in need of replacement. The F-28 fault code is a communication error between the motor controller W10163007 and machine controller W10525356. Check all of you connections one at a time by unplugging them and reconnecting them. If this produces no results, One of the two controllers have failed. The most likely is the machine controller W10525356. This is indicated by the fact that the door is locked as the motor controller doesn't have anything to do with this action.
