Hello,

This dishwasher leaks down the standpipe during the wash cycle. I cleaned the dishwasher by hand and ran wash cycles with draino, CLR, and Lemi Shine separately. I checked the float switch and it ohms at 23 in one direction and infinity in the other. Also, when I lift up on the float stem to trip the float switch the water flow stops immediately. The water level in the dishwasher when full is just below the heater element. I checked the vent at the sink and it appears okay. The dishwasher drains completely.

I thought that maybe a gasket or o-ring was missing from the float stem where it goes into the standpipe but when I order the replacement float from AppliancePartsPros there is nothing on the float stem.

I would greatly appreciate any help at this point as I am stumped. Please note that the water is not leaking from the door gasket and the water is not sudsy. It just leaks a lot of water down the standpipe hole where the float stem stick down to the float switch and this takes place during the wash cycle.

Thanks so much!

Hello Gene,

Thank you for your response. I have not seen any problems from running draino down the drain of the dishwasher. However, I did read on another post that had a similar problem and they were directed to remove or tie down the lower spray arm. I tried that and it still leaked quite a bit down the standpipe. Do you think I can make my own gasket or even try silicone calc if the float stem still slides freely?

Hello Gene,

I tried your suggestion of removing the flat washer located underneath the bottom spinner and to my surprise it did reduce the amount of leaking. It is still leaking a lot down the standpipe but not as much. Do you have any other suggestions that I might try? This dish washer is level.
