[CENTER][FONT=Comic Sans MS][SIZE=3]I started the dishwasher one evening last week, only to find it still in the rinse cycle the next morning. I was able to manually turn the dial and it did drain and shut off normally. I ran it the next day and the water did heat, but it still got stuck in the rinse cycle. Another forum indicated it is probably the timer, but since it is about $100 for the part, I want to know what I can check first to be as certain as possible that a new timer will correct the problem. I have never had to to any repairs to a dishwasher, so I’m starting from scratch. Any suggestions?

The first thing I would check for continuity is the heating element (#13 on the tub break down diagram) and the hi limit thermostat (# 18 on the tub break down diagram).
If there is nothing wrong - replace the timer.

Thank you.. I’ll be off to the home store tomorrow morning to buy my ohmmeter and start my testing. Thanks for the detailed advice! Anjanette
Hi Anjanette,
Keep me updated, please.
Gene.
Okay, how do I know how to take the continuity readings and what readings I should be getting??
Just click on the “continuity”.

Hey Gene,
I’m having this problem too. It’s stuck on rinse and I manually turn it to dry and it dries. I don’t know if this has anything to do with it, but at the same time thisstarted happening, my sink faucet started spraying at the base when turned on. No idea what’s happening?!?!?

Jess,
