Dishwasher was not heating up when running and the heated dry was not working either
The dishwasher was not heating anymore. I suspected it was the float/flood switch, so I got that ordered. I went ahead and ordered the element also and I'm glad I did! Even though the element was good, when I tested it I loosened the nut holding the element in. When I retightened it there was NO WAY for me to get it watertight again and it kept dripping out the bottom. Mine was made in 2019, and the gaskets on the element that came with it were a terrible design - the metal flange on the element was about as big as the hole in the middle of the gasket so water just leaked between the gasket "donut" hole and the element with no way to seal. The element I bought for this repair just in case had a totally redesigned gasket that sealed right up and didn't have the same design issue. So beware, if you are fiddling with the element in your process, be sure the gasket will reseal - or just have an extra new element in case it is the old (bad) design.

The flood switch was easy to find (with dishwasher on its back) in a white housing under the black circular sump.

Getting the actual switch out of that housing took some doing. I ended up using 4 small kebab sticks - toothpicks might work better- all 4 tabs have to be pulled out at the same time.

So I ended up changing out both the element (which was good but started leaking) and the float switch.

IMPORTANT!!! Before you put the dishwasher back in, you probably need to reset the thermal cutoff (TCO) on the back of the dishwasher. Follow the wire up from the element and it is the first thing it goes to. There should be a small (3mm) black button that has popped out. Press that back in. With your repair (float switch or element) it should start heating again - at least mine did.

I'm experiencing no power at the top control panel, dishwasher detergent residue in the leak pan and i wanted to know if this part is necessary to replace along with the diverter valve. If so, what does it do? Does have something to do with the leak detection capability of the dishwasher?
For model number GDT695SSJ2SS
PartSelect logo
Hello Karlan, thank you for inquiring. This Flood Switch for your model dishwasher controls the amount of hot and cold water filling the dishwasher. If your dishwasher is overfilling or underfilling, this part may need to be replaced. The symptom you are describing of no power is more likely to be due to a faulty Door Latch, part number PS6447681 for your model dishwasher. I hope this helps and good luck with your repair!

My DW has no symptoms other then the dishes are very wet at the end of the cycle, even with heated dry or high temp wash. I checked the heater element, and I got just under 15 ohms, so I believe that's fine. I don't know if it could be the flood switch or the thermostat. I appreciate any advise you can give me.
For model number GDF530PSM0SS

Hello Carl, thank you for contacting us. The most probable cause of the issue is a faulty thermal cut-off thermostat (fuse) which is a part of the wire harness assembly, part number PS12716569. When faulty, it can affect the heat production of the dishwasher which can result in wet dishes at the end of the cycle. If this is not the case then the flood switch, part number PS12068856, is the likely culprit. We would also recommend cleaning the filter and drain hose to ensure the dishwasher is draining properly. Customer service is available 7 days a week if you require assistance placing an order. Thanks again for reaching out!

Dishwasher water does not get hot. The technician said the heating element was good but a temperature thermistor was bad. He said it was located inside the float switch. Does this make sense? If so, what part should I be looking at?
For model number GDT655SSJ0SS
PartSelect logo
Hi Stephen, Thank you for your question. The part he was likely referring to is the high limit thermostat. It is connected to a wire harness. The part number listed under your model number for the high limit thermostat is PS12577531. If you would like to place an order for it, you may order it either online or by calling our customer service line and anyone will be happy to assist you. We hope this helps!
