If your dishwasher leaks, check these:Main tub sealDoor gasket or sealWater-inlet valveHoses
Main tub seal
Note…If the main motor of your dishwasher is mounted vertically, beneath thecenter bottom of the dishwasher, the following instructions probablyapply to you. But if your motor is mounted horizontally, the pump isn'tserviceable--you need to replace the entire pump and motor assembly.
Themain tub seal is beneath the drain impeller. It prevents the water inthe dishwasher from leaking out near the shaft of the motor. To get tothe 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
Overtime, door gaskets and seals harden and lose their ability to sealproperly. You can't repair the seals. You need to replace them ifthey've begun to leak.
Thewater-inlet valve, itself, seldom leaks. But, the water-supply linefrom the house and the rubber tube leading from the valve to the insideof the dishwasher may leak. Tighten or repair/replace these asnecessary.
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 thedishwasher, and replace the valve.
Behindthe lower access panel on your dishwasher are several rubber or plastichoses. If the leak appears at a connection, try a new clamp. If thatdoesn't work, replace the hose.
