Burned wires in a Whirlpool dishwasher

4 posts in this topic

Hi,

 

I recently acquired a free Whirlpool GU1200 dishwasher, which the prior owners said worked, but wasn't cleaning well any longer. I'd like to get this DW running again. Upon closer inspection, I saw that the heater element had burned out at the spade of the element and terminal of the supply wire, as evidenced by the burned wire and nut. I have purchased a new heater element and nut and am ready to try to repair this puppy. However, I'm unsure of two things:

 

1. The insulation around the wire is burned. I plan to clip off the terminal and about an inch of the burned wire (clip off all the burned stuff, in other words), and attach a new terminal (and some add'l wire if needed). Given that the insulation around the wire has been burned, has this compromised the integrity of the *entire* wire? Is it ok just to clip off the affected section of the burned wire? Or do I need to replace more (or all) of the wire?

 

2. I'm assuming that the heater element just died and caused the short which burned the nut and wire, as seen in the attached photo. Is that a reasonable assumption, or is there some other culprit that I should investigate? I'd hate to put the new heater element in only to have it burn out immediately due to some other un-diagnosed issue.

 

Thanks for any thoughts!

The poor cleaning complaint may be totally related to the defective heater.

Clipping the bad wire back to good wire should be fine.

The burned terminal could have been due to a loose terminal connection.

The hi-limit thermostat should also be checked for correct function.

the new Heater won't burn out right away, unless it physically shorts

You should use hi-temperature Connectors

Thanks for the advice! A few follow-ups:

 

1. For the high limit thermostat, do I just want to check for continuity? And if so, do I need to do something to the thermostat to activate the circuit (e.g. put a hairdryer to it)?

2. For the high temp connectors, can I get those at an auto-parts store?
