If you’re having problems with your Maytag Dishwasher leaking while it’s running, then you’ve come to the right place to troubleshoot your issue. This guide will help you get to the bottom of the problem of your dishwasher repair and help you solve the problem as quickly as possible. 

If you have one of either of the following models, this is the right guide for you: 


The most common problem associated with both MDB6769PAB0 and MDB6769PAB1 models of the Maytag dishwasher is that is leaks while it is running. If this is occurring for you, it may be for one of the following reasons: 

  • The door gasket is worn and needs to be replaced
  • The water inlet valve needs to be repaired or replaced
  • The drain hose needs replacement
  • The hose clamp or fill hose is leaking or installed incorrectly
  • Excessive suds are being created

Fixing a leaking MDB6769PAB0 or MDB6769PAB1 is usually fairly straight-forward, and should take you less than thirty minutes on average.

Door gasket replacement

Over years of usage, door gaskets can become compressed or torn. 

To replace the door gasket in your Maytag, you won’t need any tools other than your hands, and the gasket which is part number W10542312. From there, open the dishwasher door completely.  Reaching into one corner, you’ll start manually pulling the old gasket out. It should come out easily in one or two pieces. Clean where the gasket was with an old rag, just make sure there is no debris or build-up that will prevent the gasket from being installed correctly. 

To install the new gasket, ensure that you are placing the ridged side down into the frame. Press the gasket into one of the lower corners; getting it started will be the most finicky part. From there, press the gasket into place, making sure not to stretch it as you press into the corners.  Double-check that the gasket is pressed in securely. If the door closes, your repair is finished. 

Water inlet valve

The inlet valve controls the level of water flows into your Maytag dishwasher. To replace the water inlet valve on either your MDB6769PAB0 or MDB6769PAB1 dishwasher,  you’ll need to first purchase the part W10648041. For tools, you’ll need both a Phillips and a flathead screwdriver, a 5/16 and a  ¼ inch nut driver, a ⅝ open-ended wrench, and finally, a pair of pliers. 

Begin by unplugging your dishwasher from electricity, and by shutting off the water to your dishwasher. You don’t want to be electrocuted, or accidentally have a big water mess on your hands. 

Remove the two screws that mount the dishwasher to the counter. The water line connected to the valve should be easily removed with the open-ended wrench.  From there, loosen the hose clamp using the 5/16th nut driver, which is connected to the air gap. 

Pull out the dishwasher, and remove the access panel which looks like the small kickplate at the bottom of the dishwasher. With the dishwasher lying on it’s back, you’ll be able to easily spot the water inlet hose, which you’ll want to detach with the wrench. Unscrew the 90-degree elbow either by hand or the pliers. Slide the entire remaining valve off of the dishwasher, and slide down the hose clamp. Work the hose off of the valve either by hand or with the flat-headed screwdriver. Push down the locking tab, and you’ll have the old water inlet valve disconnected.

To connect the new one, take the same steps in the reverse order, first by plugging in the power, then connecting the inlet hose. The bracket tabs should be easily slid back into place.  Once in place, connect the new 90-degree elbow without overtightening, connect the water inlet line, replace the kickplate, and slide the dishwasher back into place. Remember to attach the hoses you’d previously removed, and attach the dishwasher with the previously removed screws. Once you plug your dishwasher in and turn on your water, you should be back in business. 

Fill Hose

If your hose clamp is installed incorrectly or your fill hose happens to be broken, make sure you have the correct fill hose part: W10878507. 

The fill hose connects the water inlet valve to the dishwasher. Begin by unplugging the dishwasher from the electricity, then opening the dishwasher door and removing the lower dishrack. 

On the left side of the dishwasher, you’ll see a large nut that keeps the inlet in place, so go ahead and remove this with a large set of pliers. Remove the Philips screws that connect the dishwasher to the counter, and remove the access panel along the bottom as well. Pull out the dishwasher until you have enough room to access the left side of the dishwasher. It will be covered by thin insulation that you’ll need to carefully detach so you can reuse after the repair. 

Using the pliers, loosen the hose clamp from the inlet, and pull the hose off from the inlet. 

Follow the hose up to where it connects at the top, and repeat by loosening the hose clamp and pulling the fill hose off the top valve. Pull the old hose clamps from the old hose to use on the new one; with pliers, slide on the hose clamps to the new hose. Now, it’s time to attach the new hose by attaching it to the two valves in the same manner that you removed the old one. 

Make sure to reinstall each piece in the same fashion you removed it, and don’t forget to plug in the electricity when you’re finished. 

Excessive Suds

This is the most straightforward repair if your Maytag dishwasher is leaking. If your suds are overflowing, make sure you are measuring the appropriate amount of detergent, as well as using dishwasher-safe detergent. Detergent that is intended for handwashing dishes will create too many suds and is not intended for dishwashers. 

If you have soft water, you can use less detergent than if you have hard water. If sudsing continues, you may want to try a different detergent brand entirely.
