My brand new 17-yr old Superba
We built our house in late 2000. We installed a Whirlpool Superba Dishwasher which has always run flawlessly. Recently, the soap dispenser door began to fail to lock shut and the top rack wasn't drying very well. After going online and locating the parts, I called PartSelect to confirm that the legacy repair parts would be compatible with my older, NLA dishwasher. The phone support/sales agent was fantastic and recommended the appropriate parts. I ordered on the call and got my parts 2 days later. In the email confirming that the parts had shipped were links to videos showing the installation procedures. I followed both instructions and completed both repairs in about an hour, including cleaning up 17 years worth of goop behind and around both pieces. I know have sparkling, dry dishes when I open the dishwasher. it's like a new machine, for about 15% of the cost of buying one. I couldn't be happier.

The light on the option panel "Hi-Temp Scour" is on.
I spent $290 in parts (4 in total). I replaced all of them. I resetted clicking 1,2,3 and 1,2,3 and 1,2 3 and then click the button normal. But The diswasher is still not working. The "hi-temp Scour" is still on. I would like to ask to the dishwasher technitian, why the diswasher is not working even I replaced the 4 parts related to the temperature? I followed all videos to replace the 4 parts and resett the dishwasher, but the dishwasher is not working. Thanks.
My dishwasher's heated dry cycle wasn't heating up
After pulling the dishwasher out from under the cabinet, I found it underneath near the back right side. I disconnected the old thermostat, unscrewed the clamp holding it into place, put the new thermostat in, screwed it back in and replaced the two plugs. Then I pushed the dishwasher back into place, and it initially didn't work until I found an online forum that was able to identify the reset command for my dishwasher (for the WDT710PAYM4, press any three buttons in a sequence of 1 2 3 1 2 3 1 2 3. After completing that all the lights lit up, and I shut the door leaving it for half an hour) Once the reset finished, the heated dry worked like it was suppose to.

No heat. Replaced thermostat
Was able to replace and repair without taking the dishwasher out. Thermostat is behind and to the left of the power junction box. Has 2 wires going to it. It is up against the bottom of tub. I used an angled mirror to see what I was doing. 1 small screw to detach and pull down thermostat. Be sure power is off before you start. Also reprogrammed defaults. Hit any button 1-2-3, 1-2-3, 1-2-3, fast and close door. Let it sit 15 min to run and re-set defaults. Now I have heat and dry dishes.
Easily replaced motor and pump per video. Located high limit thermostat looking up from bottom and held on with two screw bracket. Reset code: push "Hi temp scour" then push "Air dry" then repeat push of "Hi temp scour" / "Air dry". Works like new - thanks.
My dishwasher quietpartner ii was not cleaning my dishes. It seemed it was not heating correctly that the Hi temp wash or the heated dry.
I loooked up the main problems associated with that model which is provided on the website and ended up ordering a heating element and a thermostat. I replaced both parts it took me about 30 minutes. The dishwasher is working again and my wife is very happy. Thanks guys!!!

dishwasher did not completed the drying cicle. heated dry button blinking
I just changed all parts that could make any effect in temperature control. even the thermal fuse. this was easy,looking in details all the drawings you have in your page. so I pulled out the dishwasher changed the parts and ready!! it work great now . thanks for your guide and help.
I shut off the power to the dishwasher, then I removed the front panel under the door. On the right side just behind the electrical box there are two wires going up to the hi-limit thermostat, (you may need a small mirror to see it), remove one screw that is holding the thermostat bracket, unplug the wires from the old thermostat and install new one. Screw bracket and thermostat back to the underside of the dishwasher, reinstall the front panel, turn on the power, done.

Unit Wouldn't Work. "Clean" Light Blinking
The unit had power, but the controls would not work. The "clean" light was blinking. I first replaced the control unit, no help. I then used the "just ask" and was told the problem was the heating element and/or the hi-temp thermostat. I replaced both those and used the re-set code pushing the "hi-temp/air dry, hi-temp/air dry" buttons. That did it. Easy parts to locate and replace. It took longer pulling the unit out and putting it back than it did to replace the parts.

My dishwasher is not getting hot. The water going in is hot but it doesn't seem to be hot inside during the running cycle. I put it on high temp and heat dry to no avail. Heating element? Also, the little red button on the back of hose that connects to the faucet, when i draw water from it while dishwasher is running, it isn't hot water either.Thank you!
For model number WDP350PAAW1
Hello Ashley, thank you for contacting us. It could be the high limit thermostat, it could also be the heating element. You can test these with a multi meter. Good luck with the repair!
How can you tell if the high limit thermostat is not working and how can you check it to see if it is bad thanks
For model number Adb1100aww5
Hello Frank, Thank you for the question. The thermostat should read closed at room temp. You can test this with a multi-meter. Hope this helps!

I have water to the machine and it starts and seems to run ok but is not cleaning well. I do not seem to have good cleaning pressure. I have cleaned all the filters and spray arms and changed the water inlet valve.
For model number WDF540PADT1
Hi Brad, Thank you for the question. The drain hose may not have a loop in it. The fill water may be draining out of the dishwasher by going straight out the drain hose. Be sure that your drain hose is not simply laying straight. It must have a loop in it or be off the ground so the water is not gravity fed out via the drain hose. You can also try to empty the dishwasher, set it to run a wash cycle. Let it fill with water as normal. When the dishwasher begins the cycle, open the door and see if the water level is just under the heating elements.If there is not enough water there may be a clog in your water fill line. Remove the fill hose where it attaches to the fill valve. Check to be sure there is nothing clogging the screen on the inlet fill valve. Also check the water fill line for blockage. You can also check the Overfill Control Switch if it is not filling with water at the correct level. If it is defective it can shut the water flow off too soon. Hope this helps!

My dishwasher water does not get hot. We have tested the heating element and the high limit thermostat with a multimeter and they are both functional. What else could it be?
For model number Kenmore 665.13123k703
Hello Drew, Thank you for your inquiry. I would also check the bi-metal fuse/thermal fuse, door switch-and wires going from it to the control board, and the control board itself. Hope this helps!

Sanitize light blinking at end of wash cycle. Heating element bad? Thermostat? Water entering machine is above 120f prior to start.
For model number WDF530PAY0
Hi Josey,
Thank you for the question, the flashing sanitize light indicates it did reach the sanitize temperature of 140-155 degrees in the final rinse. You can try running the hot water in the adjoining sink to get the hot water up to max temperature before starting the dishwasher. If this does not help try opening the door a bit during the wash cycle to see if there is steam indicating the water is hot. If the water is not getting hot then you may need to replace the heating element.
Hope this helps!

Thank you for the respond, are you referring to thermal fuse part #: W10344801? Isn't this part to shut the dishwasher off if the dishwasher shorts out or overheats? Regards
Hi Bahman, Thank you for the question. This part is used as a safety device to protect the dishwasher circuit from overload. If the temperature gets to high it will shut off the electrical current to the heating unit in the appliance. Hope this helps!

I've replace the high limit theromastad and the door lock control. It wants to start you can hear water going into machine but then nothing happens. Any ideas of the possible problem.
For model number wdt720padm2
Hello Richard, thank you for your question. If there is water getting into the unit but the appliance will not start the cycle you will want to test the motor to see if it has failed. If the motor is fine, the issue would be with the electronic board which would have to be replaced. I hope this helps!

My dishwasher won't run and i think the switches are both fine. If the high limit thermostat is bad will it prevent the machine from running at all or just affect the operation or heating?Thanks.
For model number DU912PFGQ2
Hi John,
That is a good question. It may cause the situation you are describing. Another part that may fix the issue could be the door switch kit as well. You may need to contact Whirlpool for more information. Their telephone number is 1-866-698-2538. I hope this helps. Thanks and have a great day!

My jenn air dishwasher does not heat the water during the wash cycle. I test the heating element by running a function called plate warmer and it works fine , the element gets very hot. I pulled out the high limit thermostat and attach the digital volt meter and it shows continuity (normal closed). Can i test to see if i apply heat to it opens up and digital meter read open? What is causing the water not heat during the cycle?
For model number JDB3600AWP5
Hi Bahman,
Thank you for your question. Well, if both your heating element and your thermostat are testing that they are working, then the only other parts to check would be your bi metal fuse, and your electronic control board. I hope that helps. Good luck with your repair.

My heating element snapped in half so i replaced it, but the element never seemed to kick on. The dishes are soaking wet and there are suds in the bottom of the dishwasher, which has never happened before. I am assuming that whatever is wrong must have snapped the element in half. Could the high limit thermostat cause the heating element to never come on?
For model number WDF530PLYB2
Hello Chris, Thank you for your inquiry. Since the high limit thermostat will shut down the heating element once it reaches a certain temperature, it could be causing the issue. You can test it with a multimeter to see if it has continuity. I would also double check the wiring going to the heating element for any visible damage. Hope this helps!
