HI. this is a inlet assembly issue. The water inlet valve can be identified by the water hoses connected to it. One hose will lead from the valve to the pump/motor assembly in the center of the dishwasher. Check that the hoses are securely connected to the valve and that there are no kinks in the hoses which could restrict water flow. There are two wires (four, if it has two solenoids) connected to the water inlet valve. Label the wires and connections so that you can properly reconnect them later. The wires are connected with slip on connectors. Firmly pull the connectors off of the terminals (do not pull on the wire itself). You may need to use a pair of needle-nose pliers to remove the connectors. Inspect the connectors and the terminals for corrosion. If either is corroded they should be cleaned or replaced.

Use a continuity tester or multimeter to test for continuity. Set the multimeter to the ohms setting X1. Touch one probe to each terminal. A reading of infinity indicates a bad solenoid that must be replaced. Different brands and models will have various measurements, but the valve should show some resistance if it is functioning properly. If your valve has two solenoids, test the second one in the same way as the first.

If the solenoid is working properly, but water leaks through the valve even when the dishwasher is off, then the valve itself is the problem. Debris may be preventing the valve from closing. If the valve cannot be cleaned, it will have to be replaced. The valve can also fail mechanically. So even if it passes the electrical test, it may still require replacement. If you have ruled out all other possibilities, go ahead and replace the valve.

***(((NOTE-- It i possible that the valve housing has cracked as well. make sure that the hoses are connected properly during your testing. If there are no hose issues, this will be a defective valve assembly)))

Hi, I have a Maytag Mdb8959sas dishwasher that was leaking during a normal wash cycle. I pulled the dishwasher out from under the counter and saw that it appears to be leaking directly below the point...


I will assume that you have cleaned gasket around door and at washer. Quite often a build up of scale at lower gasket surfaces is all that is causing leak.

Water leaking out of bottom of maytag dishwasher


Maybe it is leaking from the water valve that is just ouside of your dishwasher, There is a flexible line attached to the water valve that goes into the dishwasher where it is also attached. Get a flashlight and look around, if you see the valve see if the connection is leaking. If it is, see if you can tighten it. You can also shut the water to the dishwasher off here. Don't forget to turn it back on after repairs.

Dishwasher Not Leveled

This is a very common reason for a leaking dishwasher especially if this was a new installation. The framing in a dishwasher is made up of mostly thin sheet metal, so if it is not sitting flat and level things can get distorted very easily.f3a0b0dc-c8b0-4678-bccb-f94392039827.gif

Door Seal

This is not very common in most dishwashers. To check this look for rips and distortion of the seal. If it is ripped or distorted you will need to replace.

Dispenser Seal

This is a more common place for a leak to develop. This is easy to check, remove the front panel and carefully inspect around the seal for water dripping or stainage. If any is found replace the dispenser gasket.

Water Inlet Valve

Usually it is the connection to the water inlet valve that ends up leaking. Check this connection ( there is usually some sort of adaptor between the valve and supply hose) for leaks. Check the connection on the back of the water inlet valve also. Ocassionaly a water inlet valve will leak around the solenoid in this case replace the water inlet valve.

Drain / Circulating Pump

Some dishwashers have separate drain and circulating pumps Some use one pump to serve both purposes. In either case you will need to check the housings for leaks along with all the connections. Some dishwashers have a seal that leaks down into the pump . This is easy and inexpensive to replace. Follow the tutorial on replacing the pump.

Door Latch

The door latch can become loose or misalinged. Check both the striker and the latch. To adjust the latch you will need to remove the front panel and adjust switch until properly aligned.

Door Hinges

They can cause problems, but this usually only happens from opening a heavy load of dishes on the door. Occassionaly a broken spring or cable occurs. You will need to remove the tow kick and maybe the front panel to inspect.

Dishwasher leaking from underneath


Possible that the drain hose is leaking , the drain valve /pump is leaking or the the inlet hose is leaking. You need to observe with a good light under to see the point of leak and infer.
maybe a hose clip is bad and will need to be tightened or the valve needs to be removed , cleaned and reset.

My dishlex dishwasher overflows


The only part that physically allows water to enter a dishwasher (upon receiving power from the control) is the inlet water-valve. I would test the inlet water-valve located directly where you in-coming water line is connected to.

Shut-off power to the dishwasher and remove the 2 prong connection to the water-valve solenoid (small, black, batter size). Test the solenoid for continuity; if bad, replace the entire inlet water-valve (cost about $20)
