How to Troubleshoot & Replace Samsung AP4579881 / DD32-00005A Dishwasher Thermistor

The model number on the dishwasher did not have a -0000 or -0001 on the end of the model number so I bought the part for both models. I assume if yours doesn't have it, then it is the -0000 model like mine, which of course means the more expensive part. You can always buy both and return the one you don't need. Replacing the temperature sensor was fairly simple - disconnect power and water, pull the right-side panel off, move the noise filter out of the way, turn the sensor a quarter turn counter-clockwise and pull it out, then swap the o-ring to the new sensor, and then reverse the steps. Before pulling out the old sensor, have some rags or paper towels on hand to absorb the water that will leak from the housing when there is no sensor to stop it. Dishwasher now runs full cycles without issue.

I researched the part that I needed. I found it on AppliancePartsPros and had it shipped. Shipping was amazingly fast, customer service was very helpful. I was able to put the dishwasher and its back, access the bottom panel and easily take out the old one and replace it with the new one in about 15mins. It works like a charm.
