Frigidaire Dishwasher Displays HO

My Frigidaire dishwasher (Model GSB5755DS) is taking forever to finish on the light cycle. When I start the display reads 89 (this is for 89 minutes) then it jumps down to 54 (54 minutes) a short time after that the display will read HO. The cycle then may take up to 3 hours to complete. My hot water is very hot so I’m wondering if it is the hot water sensor. Has anyone run into this before?

Did you ever get a fix for this? My DW does the same thing. We just started running it at night since it takes SO LONG. i just accepted it as a fluke, but I would really like to fix it. I even turned my water heater up. No difference.

Anyone,

bump. Anyone?

Anyone?
It’s been a while, but I thought I would ask again.

Here are your parts

Here is the tech sheet

And here is the closest thing I could find in a manual

If they use the same thermistor which is likely, it should be 10,000 ohms at 77 degrees F.

I would also check the heating element and the hi-limit thermostat.

Thank you so much. I will see what I can do from there.

Thanks again.
