Question about Maytag 24 in. DWU7402 Built-in Dishwasher
dishwasher leaking might be due to either of these causes, check these:
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,
* Lower rack
* Spray arm support
* Wash/drain impellers
Then try 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.
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.
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.
