Whirlpool Gold Dishwasher won't drain

[flyineagle]

I have a Whirlpool Gold d/w that will not drain. I have taken everything apart and could not find a blockages in the drain nor in the impeller or anywhere inside the dishwasher. I removed the drain (white plastic tube) coming out of the bottom and did not find anything there. I did not take this piece apart as I didn't really see anything but also, I'm afraid of breaking it while trying to take it apart. The drain line is clear, as is the plastic piece that sticks out of the top of the sink (again, I didn't take it apart as I was afraid of breaking it).  I have reassembled everything and pressed "pots/pans". Some water went in but that was it.  I then hit "cancel/drain" and a click is heard and it sounds like it wants to run, but then it clicks again and nothing. I'm not handy enough to check voltage or anything like that. Am I to the point of needing a repairman? Or is the puppy sunk? Not sure if I read the model number correctly as it is smudged/worn off. The serial number (I think) is FJ4733072. Don't know if that helps or not.  Any suggestions would be great!  Many thanks to you and your service.

Model GU940SCGB

Hello,

If you look under the dishwasher at the motor and around the motor shaft does it look like it's been leaking water? Maybe not leaking enough to get the floor wet, but just the motor?

Sounds like your motor is stuck if it's clicking out on the over load after it tries to start running.

Yes, the bottom has a build up on it. We have hard, limestone water here & it looks like  something that has been wet or exposed to moisture for awhile, with no water on the floor.  Also, I failed to mention this eariler - when the cancel/drain button is pushed and I hear a click, I then hear what sounds like an "electrical" sound like something sizzling. I have not been able to see where it is coming from, nor is there any smoke or a smell.

Many thanks!  What do I do now?

Is there a build up around the motor or motor shaft under the dishwasher?
The motor should be clean looking, if not the seal is leaking and if the seal leaks the motor will get wet. This will damaged the motor.

If the motor is clean looking and you can't find anything stuck in the pump that would keep the motor from turning I would then check the voltage to the motor. If you have 120 volts to the motor and it still does not run you would need to replace the motor.

Good evening!
I've had this thing taken apart in the inside. Should I try running something through to the drain out the bottom? The outside of the motor is covered with a buildup that looks like it has been exposed to a lot of moisture.  Haven't noticed any water on the floor - could it be such a slow leak that it would only cause the build up?

I'll take it all apart again and see if I can find anything down through the drain.

Thanks again for your help & ideas.

Updated info to Whirlpoop tech:

The correct model # is GU940SCGB, serial # is FJ4733072.

Sorry for the wrong info...the # is smudged on the machine and it took some doing to figure out the correct number.

Again, thanks for your help!

I updated the topic to include the correct model number information, thanks.

Did you get the dishwasher repaired?

[flyineagle]

Morning, AJ - finally got the cash to order a motor which came VERY fast - that was cool. Got everything taken apart and found the reason for the "sizzling" sound mentioned earlier. The plug is burnt and black - both the plug and where it goes into the motor. So, this morning I ordered the wiring harness and am looking forward to getting it just as quickly.  Any remarks or further suggestions you may have will be greatly appreciated!!

[flyineagle]

Hello again, AJ & all...replaced the motor and the wiring harness and was very careful to pull an old plug and immediately replace it with the corresponding new plug on the new harness. Dishwasher started and ran for about 10 minutes when I heard what sounded like a circuit breaker kicking off, but there are no circuit breakers in the kitchen. The dishwasher shut off immediately and now has no power whatsoever.  Nothing works and I'm left again w/ a dishwasher w/ water standing in it.  Please - any ideas?!!?!?!

There is a thermal fuse in the control console that probably blew. When you open the control panel it will be on the right hand side.

Jumpy what would cause his high limit to kick out?

I think this is what jumptrout51 is talking about.

Thermo Fuse

JW, this is a common problem I see with these.
If you click the link above you will see the new thermo fuse comes with two new leads.
This is because the old leads come loose and create a bad connection that creates heat.
The heat from the bad connection blows the thermo fuse.

This is why you need to use the new wire connections that come with the new thermo fuse.

[jumptrout51]

Yes. That is the one.
I learned the hard way to switch the wires.

I hate to say it, but me too.
