Water Leak at vent area in door...

Water is leaking at seal area of vent between door liner and galvanized inner panel. After dishwasher starts wash cycle water comes out through bottom of door and onto floor. No water is coming out through vent to outside of door. No water is leaking around soap dispenser. Any help would be appreciated.

    Thanks, catriver, I replaced the wax motor, it appeared to work OK, but apparently did not close the vent door fully. This corrected the water leaking down from the vent, however we still had a leak coming from the bottom of the door, found that the lower spray arm was beginning to split, causing water being forced under the inner door panel and leaking at bottom of door. Thanks again for your help.

    I closed the vent area off, but water still leaks out of the bottom of the door. This under counter Model #DWU9200ABX, we think its over 20 plus years,

    water leaking down the dishwasher air vent

  • Anonymous Mar 28, 2014

    I have a Kenmore Model #665.13193K902 that is getting the insulation wet on the left side which is also leaving a water stain on the outside wall of the cabnet next to it. There is a hose loop located in that area but it is not leaking. This model has a vent on the top of the door on the left side. No water on the floor just wet insulation. Is this a vent problem? Should I not use the heated dry feature?

On this model the vent is open and shut by a wax motor. The vent should be closed tight during the entire wash cycle and the first 6 minutes of the drying cycle. Check the operation, make sure there is not a bunch of gunk restricting it. If you are handy with a meter check the resistance of the motor. It should read approx. 2100ohms. Another reason for leaking at the base is oversudzing. Also check the upper spray arm for cracks or splits shooting water into the vent area. Catriver...post back.

Hello, Thank You for using FixYa. I will be helping you today.I would start by removing the outer door panel remove the screws around the inner door to do this.Then close the door and start a cycle. Sometimes you can see obvious signs of leaks just by removing the panel too. But if not let it run and see if you see water leaking anywhere. You will see water in the bottom corners its normal. If water is splashing over those corners the check the lower spray arm gor damage or cracks it can cause this problem also make sure the screws under the spray arm are tight. also check the upper arm.
Thank You and please rate my answer if it was helpful..

KitchenAide Dishwasher KUDS01FL leaks water

i have had mine leak (usually out of the left side) I can see it coming off the black rubber seal that ends about 2/3 of the way down the side. ( I have also replaced the inner seal around the tub- that helped as the bottom of the seal would stick to the door when closed and make a gap for water to come out) I also notice that water and moisture comes out at the top of the dishwasher (then it leaks down the side and front) I have heard of many problems with the latch...and I can push mine closed tighter but it doesnt close completely with just the latch, but enough for the wash cycle to work. also just make sure there are no crumbs or something stuck around the liner. good luck mine has been a lemon and i cant wait to get a different brand.

SPRAY ARM ASSEMBLEY NOT TURNING ON MY BOSCH DISHWASHER, ALSO WATER JUST DRIPPING THROUGH SPRAY ARM

If your dishwasher leaks, check these:

Main tub seal
Door gasket or seal
Water-inlet valve
Hoses
Main tub seal Note… If the main motor of your dishwasher is mounted vertically, beneath the center bottom of the dishwasher, the following instructions probably apply to you. But if your motor is mounted horizontally, the pump isn't serviceable--you need to replace the entire pump and motor assembly.

The main tub seal is beneath the drain impeller. It prevents the water in the dishwasher from leaking out near the shaft of the motor. To get to the seal, which is inside the dishwasher, remove the:

  • Lower rack


  • Spray arm


  • Spray arm support


  • Wash/drain impellers


Then pry the seal out of its housing and replace it.

Door gasket or seal Over time, door gaskets and seals harden and lose their ability to seal properly. You can't repair the seals. You need to replace them if they've begun to leak. 

Water-inlet valve The water-inlet valve, itself, seldom leaks. But, the water-supply line from the house and the rubber tube leading from the valve to the inside of the dishwasher may leak. Tighten or repair/replace these as necessary.

The water-inlet valve could mechanically stick open. When that happens, the water continues to flow into the dishwasher, which then floods your kitchen. Turn off the water supply to the dishwasher, and replace the valve.

Hoses Behind the lower access panel on your dishwasher are several rubber or plastic hoses. If the leak appears at a connection, try a new clamp. If that doesn't work, replace the hose.

Door leak

Br, couple of things you can look for here. Check the vent, you can just pop this out. Sometimes there is a buildup of gunk which will hold water during wash and leak down between the door. There is a seal there, part number 974782. Another thing is to check the upper spray arm for cracks or splitting. This can send a direct flow of water into the vent. There is also a seal at the bottom of the upper spray arm, part number 3376846. I was fooled by a leak like this once, it turned out to be a clogged vent...Catriver..post back.
