GE GDF510PSD0SS Not Drying/Dishes Not Clean

[Kagoo912]

Hi Everyone, new to the Board but have browsed before.

 

I have a GDF510PSD0SS that's about 5 years old.  We started noticing the dishes were wet after heated dry and they weren't very clean.  It appeared to me that the heater element may be the culprit so I removed it and checked resistance, got a reading of about 16 ohms.

Assuming any continuity was a good thing so I checked some forums and found a few threads indicating that the Flood Sensor has a thermistor inside and other people had good results when changing it. I ordered and installed the new Flood Sensor but the problem continues.

Next step was to try the Diagnostic Error Code Mode (should have done this first but only learned of it on the forums) but I do not have the Service Manual for this exact washer so I can't correctly interpret the results.  I found a Service Manual for a similar model but the results are confusing.  When in Diagnostic Error Code Mode the Heated Dry and Clean LED's are illuminated, the similar model Service Manual shows the Heated Dry LED indicates 3 of last 5 washes did not reach 120 degree wash temperature, this makes perfect sense.  The problem is the Clean LED indicates a failed Turbidity Sensor but my model doesn't have one of these!  I did a visual check (couldn't find it) and looked at all the available parts there isn't one listed.

So I need some help with the following:

1. I'd appreciate the Service Manual for my exact dishwasher GDF510PSD0SS
2. I'd appreciate any help interpreting the LED's in Diagnostic Error Code Mode
3. Any help with next step or potential fix.

Thank you in advance!

No big deal, models without a turbidity sensor will give you that error; just ignore it. 

Use that same diagnostic guide to manually operate the heater and try to determine if the heater actually heats when you energize it that way.

Change the water level float switch. The thermister for temp is built into it.

Flood sensor and float switch....what’s the difference and if there is a difference where is the flood sensor typically located
