To get the washing machine to wash I most often have to slam the lid closed several times.

You need to replace the lid switch as it sounds faulty. This is a safety device so that you can't just lift the lid up during spin cycle. Easy to replace.

Thanks. Is there a website that shows how to replace it?

None that I know of except this site will show you where it's located.

Appliance Parts Pros.com Discount Appliance Parts ? Appliance Repair Parts (http://www.appliancepartspros.com/)

Put your model number in the search engine on the site and it will show you a schematic drawing of your machine.

I use this site all the time for appliance parts.

During a wash cycle, lift the lid and see if there is a small slot 1/4 X 1/4 or so under the lid on the top of the washer. The washer should have stopped. Push a small blade screwdriver into the slot. If start up is erratic or you need to push far down, the switch is bad. The washer top, on most models, can be popped up and the switch is under the slot. Not a hard fix.

Thanks. You have been super helpful.
