water fill overflows at times
thought it could be due to the overfill control switch,so ordered one and replaced one in the washer. However, it did not solve the problem. Having a repair company coming to look at the dishwasher. Tipped the washer on its back and switch was readily accessable. Only had to open plastic covering over the switch, disconnect the wires and install new switch and reconnect the wires.

During normal cycle a lot of water is coming out the bottom of the door. This doesn't seem to happen on 1 hour cycle. Would this be a problem with the overflow control switch or another part? Thanks!
For model number WDF760SADM0
Hello Jennifer, thank you for your question. Yes, the float switch (also known as the overfill control switch) helps control the water level. If it goes bad, it is possible that the dishwasher may flood or leak. You may want to test it with a multi-meter to see if it has continuity and replace it if it does not show continuity. I hope this helps!

What does the overfill controll switch do
For model number KUDE48FXSS5
Hi Andrew,
Thank you for your question. The overfill switch, or float switch as it is sometimes called, makes sure that your appliance does not over fill with water. It also helps the drain pump know when the water has been all drained out of the machine. I hope that helps. Good luck with your repair.

My Whirlpool gold series dishwasher keeps on filling and draining it will not go to wash cycle. What do you think the problem is?
Hello Mario,
Thanks for your question. This will vary from model to model for the exact parts, but you will want to check the water inlet valve with a multi-meter for continuity, replacing it if it shows no continuity. Check the wash arm impeller inside the pump and motor, as well as considering the idea that the pump may be bad. Examine the spray arms to see if any of them are clogged and clean them if needed. Test the float switch as well with a multi-meter for continuity and replace it if it does not show continuity.
I hope this helps.

The dishwasher will not fill. Can you help?
For model number WDT720PADM
Hello Nicole,
Thanks for your question. Your water inlet valve may be clogged or defective. It could be worth considering replacing it. Your problem may also be the float switch, so replace that if the inlet valve is fine.
I hope this helps.
Machine overfills and leaks at front of door. Float switch tests good. Fill valve tested good but replaced because of some rust stains on screen. Float moves freely. Water drains normally when cancelled. What could be the solution to this problem?
For model number Mdb4709pab3

DISHWASHER - MAYTAG MODEL MDBH979SAM0
Type 577-1
Hi - we had water leaking, and at first it seemed to be the water inlet valve, and we replaced that. New part seems good, no more leaks detected there. Then I noticed a drip from the water inlet hose, and replaced that. No more leaks there. However, water was still (or now) pouring through the bottom of the front door (machine was out from its usual place under cabinet, on tile floor), and at that point I suspected the door gasket, and replaced that. However, issue was not fixed, so we then replaced the front door lower seal as the old one had some hard water build up I couldn't remove (PS11755651), and we also took out the lower (and upper) wash arm parts, cleaned those, and cleaned the upper portion of the sump pump (accumulator and filter, and top of sump pump) of gudge. And, then did our best to LEVEL the machine, which stopped the gush of water, but there is still water filling up in and then draining out of the metal tray at the bottom of the door, (above the white padded material) and coming past the door's lower seal.
For model number MDBH979SAM0
Hello Heather, thank you for the question. Since you have replaced and cleaned the most common parts that can cause leaking, we would recommend checking the float switch, part number PS11750031. It shuts the water fill valve off if the water level gets too high before the timed fill cycle ends. We hope this helps!

You suggested that I replace the overfill switch. I stated in my previous question that the float/overfill switch tested good. I checked it with a continuity tester and also operated it manually in the machine. What else in the system will cause this problem? Thank you for any suggestions you may have.
For model number Mdb4709pab3
Hello Wayne,
Thanks for your question. You may wish to check the circulation pump and motor. It is rare for this part to be causing such leaking, but you have found that most of the other parts test well, so it may be worth examining the pump and motor as well.
I hope this helps.
If the overfill control switch is bad, will it cause the washer to overfill at times, and cause water to gush out the bottom of the door?

Unit does not wash at all. I start it, let it run for 10 minutes, open it, and all the dishes are still dry. I hear a humming sound lasting about 30 seconds, it stops for a few seconds and resumes, repeating, but apparently no water goes through. I let it run a complete washing cycle, and after it is finished, soap had been dropped intact over the dishes, but was intact, not even wet, reusable.
possible causes? Thank you in advance for your help.
For model number KUDS30SXSS4
Hi Gustavo,
Thank you for your question. If the dishes are not getting cleaned because there is no water entering the dishwasher and you are hearing a humming sound, it sounds like the issue is with the water inlet valve. A component in the water inlet valve may have failed and it will need to be replaced. The water inlet valve is usually located behind the lower access panel. Remove the lower access panel in order to locate the inlet valve. Once you have located it, visually inspect the water inlet valve for any signs of cracking, wear, or other damage. If any issues are found during your inspection, you will need a replacement water inlet valve. I hope this helps. Thank you and have a great day!

My dishwasher is leaking during wash cycle, and the water is leaking out at the overfill control switch. I was going to replace the switch, but is this a different problem with a seal/gasket inside instead? Thanks for your time!
For model number IUD8555DX0
Hi Sean, both the switch and gasket could the problem, I would inspect the seal for damage and go from there. Thank you for your question and good luck with your repair!
