If the element is ok, the power to it good, it's just a software problem (bad board) while this usually does the opposite (longer cycle) the software is what controls the run time so that's all it can be. If the heater is bad it causes longer cycles ALL the time.
Sorry ignore that
Told you wrong, didn't look up your model until I went to lookup the board for you
Yours is an old timer model
correct - no board, just the mechanical timer
00032371 this is the thermostat that tells the timer to advance when the heater is hot. IF the heater is good this is shorted closed and causing it to skip heating all together. It's mounted on the bottom of the tub
you can order it from 1-888-464-2853 or if you have a local place you normally get your parts that's fine to.
so the timer is supposed to wait till the water is heated? It does seem like the dishwasher is no longer 'waiting' at certain times like it used to. I'll give it a try. Thanks
That's really all that can speed up a timer. The timer motor can go bad and slow way down but there are certain stops where it waits for the water to be heated. If it's showing hot all the time (hot like 160 not hot like 120) it will advance faster without ever pausing
I've been checking the temp during the cycle and it doesn't get over 105 or so. So it makes sense that the thermostat thinks it's already hot and tells the timer to keep on going. If one of the wires is broken would it cause the same effect? We've just had so many wire problems with this machine... that's always my first suspicion...
well not really unless the 2 going to it are shorted. This thermostat is a close when hot thermostat. So the wires would have to be melted together. I guess it's worth a check, but if wires are melting together you should be blowing breakers not running a fast cycyle
This thing is old, well past it's life expectancy. I wouldn't do any big parts on it. Timer motor etc
But for a thermostat everytime
It's only 15 bucks or so
If the thermostat is 'close then hot', that's easy for me to check.
Kill the power first these old ones use a 120v circuit to that
Yes it is old. I'm sort of hoping it will finally die... I'll be safe with the power! I'll check it the thermostat later. For now I gotta go... Thanks!
no problem. Remember to leave feedback it's how we are judged. Thanks! and lemme know how it turns out
Took out the thermostat. It was open like it should be. Was able to get it to pop closed with a hairdryer, so it seems to be working. Ran the dishwasher without the thermostat while I kept an eye on it. Went through the whole cycle - again it completed quickly - 40 min. The heating element never came on (I checked it throughout, water never got over 105). Could it be one of the high limit thermostats? (there seem to be two). If all three are wired in parallel and one of them is stuck closed it would produce the same symptom. Thanks
I was wondering whether the thermostat might be closing at a lower temp. That's why I ran it without the thermostat in place. Same result... Checked the high limit units - one of them appears to be bad. The high limit units seem to be two- position switches and are also connected to the timer advance gizmo. I think that they are normally closed (timer advance open), but when tripped, they open and the timer advance closes. I disconnected the suspect one and the machine ran normally. I'm about to order the new one. I'll keep you posted. Thanks!
Thanks for the info. I'll order the thermostat as well!
New thermostat and high limit are in. Ran it this morning and all is well.
Thanks for the help!
