I have a Maytag DWU dishwasher (don't have the model # with me) which has developed a leak in the door. Not substantial, but maybe a half cup of water will drip onto the top of the access panel during the wash cycle.
I opened the plastic panel covering the inside of the door and noticed that there was a sticky detergent-like residue that appeared to be leaking down the inside of the door from the rinse aid dispenser. I never use the rinse aid dispenser, have never even opened it until now, although previous owners of the house or our visitors may have dumped detergent in there.
I don't see any obvious way that detergent could be getting in there, however -- the rinse aid dispenser is not below the detergent dispenser, and of course whatever is put in the rinse aid dispenser isn't supposed to go inside the door.
Still, this leads me to think there is some kind of leak through the rinse aid dispenser during the wash cycle. Seals look OK, the tub isn't filling too much, the dishwasher is level, there don't appear to be any breaks in the spray arms.
I can't see any signs of a gasket or seal being missing -- is there supposed to be one?
Since I never use rinse aid, is there a way I can block up the dispenser for good?
