Dishwasher hums no action

Hi There
My faithful old Maytag dishwasher WU202 refuses to work today. It fills with water, but then just hums. I’ve tried moving the dial to different positions to no avail.

Any help will be appreciated. I hope it is something we can fix ourselves. I have found the parts drawings on your site, so I’m ready to try.

Best regards
Sue

Hi
I replaced the drive belt and everything seems to be woking OK now. The belt with lubricant and instructions on how to install was about $40 CAN. I would have ordered it from ApplianceParts Pros, but there doesn’t seem to be a Canadian section on the online form.
