LG Dishwasher Heater Element Burn Out

12 posts in this topic

My LG dishwasher (LGF7932ST) quit, flashing me a sigh of HE, HE, HE. I watched the video on installation. Removed the HE, tested it, and no continuity--dead, it was. Bought another through RepairClinic--good service, received the part in three days--and installed it. Cranked up the machine on Quick Wash, and toward the end of the wash, the machine began flashing HE, HE, HE (laughing at me I suppose). Anyway, no doubt that this HE is toast as well. For what its worth, the water in the bottom of the machine was almost warm.

 

What's happening?

Thanks for your time

Jim

Sorry, just getting the hang of this replying.

Yes, the serial number is 701KW...910KW.

 

I do not have any service bulletin.

My guess is that the resistance value for checking the heater.

 

By heater do you meat the Heating Element...yeah, I know it's a kind of simple minded question but I want to be sure we are on the same page. And, while I'm in the land of simple questions, PCB means....printed circuit board?

 

Thanks for you reply.

Jim


TPoindexter:

 

Holy Cow.  The fourth sentence should be: My guess is that the resistance value for checking the heater is in the service bulletin.

Thanks for hanging in there.

Any resistance is good, no resistance means your element is bad.

 

You can use the New PCB (EBR38144404 ) in any case

Don’t use the old PCB (EBR38144402 ) in any case

Caused by a software glitch in the Main Board (All LG LDF7932 model dishwashers)

 

If the Water Temperature is below 50F or exceeds 158F---an "HE" error will be displayed.

 

No actual defect has occurred in most cases---the Heating Elements used in LG dishwashers are generally very robust and rarely fail.

 

The revised Main Board software DOES NOT recognize an overshoot of the Target Temperature (by a few degrees) as a "fault"---and no error will be displayed.

TPoindexter, and john63:

Ordered the PCB as advised, and another HE. The RepairClinic's delivery is amazingly fast.  Busy with other things for a few days. Installed the parts yesterday and ran two successive loads of dishes. It is working like new. Thank you very much for your time and expertise.
