Overfill Control Switch

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.

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.

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.

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!

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!

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.
