Our Whirlpool Ultimate Care II stopped working in the middle of the wash cycle tonight. No noise, just stopped. Restarted it and it did it again, and again, and again. Any ideas on what might be going on? We would like to figure it out ourselves if possible. Thanks in advance!
"Middle of the wash cycle". Literally in the middle of agitating? Or is it actually at what should be the start of spin/drain?
If it is at start of spin/drain then the problem is very likely the lid switch. This is the switch that stops the spin cycle immediately if you lift the lid. The switches wear out - I replace mine every few years. Actually, I have a Kenmore, but the Kenmore top-loaders and Whirlpool have been one-and-the-same for many years. You should look up (Google is your friend) the lid switch part number based on your exact washer model number, but they are all pretty similar. Plenty of YouTube videos on how to replace the switch.
It is possible to bypass the lid switch, and I have seen that done (I have only done that myself for testing purposes) but I do NOT recommend doing that because if you ever have a situation where a full load starts draining and your house main drain is backing up you want to be able to stop the washer IMMEDIATELY by just lifting the lid.
Take a look at this YouTube video on your problem / issue.
I believe the answer could indeed be the lid switch.
