Wade for Model Number DU920PWKQ0

I've had issues with a lot of leaking that I can't seem to fix. So far, I've replaced the rubber gasket, the float and the float switch but the dishwasher is still overfilling and causing it to leak under the door where there is the air gap. I am not sure that I installed the float and float switch properly. Is the little nut supposed to be touching the metal actuator or does that matter? And the rubber washer, it invariably ends up in inside the top of the float. Is that where it should be? Or does it belong somewhere closer to the bottom? I am at a loss at what to try next; I am about $50 dollars into trying to fix my dishwasher; I am about ready to junk it and buy a new one if I can't solve this problem.

Wade, The washer should be pushed up to the bottom of the float before the float is pushed into the tub.

Irene, To access the float switch you will remove the lower kickplate. Once the kickplate is removed you will see on the right side there will be a white casing that has a cover on it that you would open. Once open the lid switch would be under the cover.

Suresh, For this issue the most likely cause will be a faulty drain pump if there are no clogs and the water is not draining.

David, You will want to check the fill valve for 120 vac getting to it when it is calling for water to be put in the unit. If there is 120 vac then the valve is faulty and would need replaced. If there is no power then check the float switch for being good and if good then would be a control board issue.

Harold, If the unit is overfilling with water and leaking then the float switch could be the issue otherwise would most likely be the water valve that is not closing completely causing the leaking issue.

Richard, The float switch will be on the right side of the tub. If you look inside the tub on the right side you will see the float and it will be located just under where that is on the underside of the tub.

R Smith for Model Number Whirlpool DU850DWGQ1

Hi there. I need some help, please. My dishwasher started leaking periodically in the last couple weeks, becoming more frequent in the last few days. Water drips off the lower left corner of the front panel, at approximately a 2/3 cup through the normal cycle. I also have water stream down the left side from the door vents, if I open it prior to the dry cycle (this started prior to the other leak). The machine is about 11 years old, and I use Finish detergent tablets, with occasional Lemi Shine to combat deposits. Additionally, I did use Affresh a couple of times in the last month. I have not torn apart the dishwasher yet, so any direction to guide my work would be most appreciated. Thanks!

R. Smith, This issue based on the information sounds like the leak is coming from the vent. If you take the inner door panel off, inspect the vent and check to see if you see water lines on the inside of the door that would be coming from the vent area. Also check your spray arms to ensure that there are not any cracks or clogging of the ports in them or around the edges. This would cause the water flow to go in a different direction and cause a leaking issue.
