How To Repair A Dishwasher Leaking Water






If suddenly your dishwasher is leaking water, we have a checklist of what to check to fix it yourself. There can only be a number of things that can make your dishwasher leak. The leak may be coming from either the front of the dishwasher or from a component or part from the bottom. You will have to find the leak and repair either a seal, a hose, pump, or other misc part. See below to fix your dishwasher that is leaking water.

DOOR SEALS LEAKING?

If water is showing up on the kitchen floor in front of the dishwasher then it may be a leaking door seal that is causing your leak. To find out, open the dishwasher door and check to be sure that the seal around the front door is not ripped or worn. If you identify an area of the door seal that is damaged, you should remove and replace it as this is the cause of your leak.



If water is coming from the bottom of your dishwasher, it is something leaking under the tub. The most common components to leak is the water pump seal and or the water inlet valve. SEE BELOW.

WRONG DETERGENT?

Before taking your dishwasher apart, be sure you are using the correct detergent. The wrong detergent can cause excessive suds. When the suds overflow they can show up as a drip. So be sure you are using the correct detergent.

WATER VALVE LEAKING?

To check to see if a water inlet valve is leaking remove the bottom plate on the front of your dishwasher and check the water valve. A bad water inlet valve will usually be a slow drip coming from the top of the valve. Look for a hard water material or corrosion on the valve itself. If you find a bad water valve (solenoid valve), shut off the water supply and replace the valve as soon as possible.

PUMP SEALS LEAKING?

There is a water pump in your dishwasher. The seals on the pump wear out. These seals are made from rubber and over time will leak. A pump seal leak can be identified as water dripping from the motor or the pump housing. If your pump leaks around the seals, remove it and replace the seals to prevent any further leakage.

HOSES LEAKING?

The leak may be coming from a recirculation hose or drain hose. These hoses are made from rubber or plastic and crack open to cause your leak. To fix this problem simply replace the faulty hose or hoses.

BAD OR STUCK FLOAT SWITCH?

Check the float switch in the bottom of your dishwasher. Make sure it is not stuck on something and be sure the switch is working properly. Test the float switch for continuity if you have a suspicion it is not working properly. Replace the float switch if it is bad.

OTHER LEAKING COMPONENT?

If none of the above parts or areas were leaking, remove the dishwasher and troubleshoot:

  1. Unplug your dishwasher.
  2. Turn off the water to your dishwasher (under sink).
  3. Remove screws holding dishwasher to counter (open door and look under counter).
  4. Roll dishwasher out from under counter.
  5. Visually inspect and look for obvious signs of water leaks.
  6. Remove and replace leaking or faulty parts and test the dishwasher for drips.
