Whirlpool LSQ8543JQ1, washer stopped full of water, will not start back up, seems like no power to it, check fuse box and everything else that is running of same.

Pretty much exactly what guest above me said. I have a lsq8543jq1 also, was stopping after agitation.

At first thought it was something more serious, since the dial seemed to make a humming/grinding/buzzing noise when it was switching to agitation cycle, but that seems to just be a timer before the drain/spin cycle kicks in.

I had a washer full of water, so rather than wait till I could get a part (or hand drain -what a pain), I just grabbed a paper clip and rigged the switch so it thinks the door is shut and voila, drains and finishing cycle as I type.

The switch is a safety device to prevent accidents; bad injuries could result if the door is opened while the washer is in spin cycle. I don't recommend this as a long term solution - especially if you have kids. I have 2 and will be ordering the new part asap.

Replace the lid switch. This is a top-loader, correct?? If it filled with water, went through agitation, then just stopped before pump-out, the lid switch is bad. Lift the lid. You will see a small rectangular shaped hole on the right side. The lid switch actuator is there. When you close the washer lid, you should hear a click just before the lid fully closes. If not, your lid switch is broken and not actuating. Good Luck ! ! !
