  2. Check you are using the right detergent. You could have seen this with your washer. An excess of detergent or the incorrect type could lead to too many suds, the soap suds spill over resulting in a spill.
  3. Investigate your dishwasher door closes correctly. If it does not there may be a blockage, or you may have to replace the hinge or the locking mechanism.

Before you do anything else make sure you disconnect the appliance.

Door Seal

The most usual place for a dishwasher to leak is on the door, luckily it is likewise one of the easiest problems to solve.

If the leakage is occasional the problem might be as simple as a large plate or another object putting pressure into the door and preventing it from closing properly.

On the other hand the door seal may have come out of place or been split.

Examine the door gasket and also check for any brittleness, mineral deposits or other gunk, or any areas in which the seal has separated from the door.

Extracting the gasket and allowing it a good clean might improve the situation in some cases or you might be required to buy a new gasket and replace it.

Water Inlet Valve (Solenoid Fill Valve)

The inlet valve can be a further everyday issue. The inlet is usually found on the underbelly of the machine which means you will most likely need to take off the toe board and might have to unscrew the door cover.

The inlet valve opens and closes to allow water into the dishwasher at different times during the cycle. The fill valve might be damaged, shown by a slow drip, or it could be damaged thus not functioning fully while the dishwasher is running.

When the inlet valve fails to shut fully this can lead to the dishwasher leaking.

In General water inlet valve cannot be refurbished unless it is just the rubber gasket that is faulty, thus the entire valve would have to be changed.

Leaking Hoses

Your dishwasher uses hoses to fill, drain and redistribute water during the cycle.

Two issues can arise with hoses.

  1. The gaskets might get damaged or the contact points might come loose thus it’s worth having a look at all the connections first.
  2. The other fault than could often happen as you use the machine is that hoses could be broken or cracked.

If you can identify that the leakage is a result of a faulty hose this should be simple to change and spare hoses are readily available.

Pumps and Seals

You can visually investigate the rubber gaskets surrounding the water pumps or motor to determine if there is a leak and replace them if there is.

The Float Switch

The float itself or the float switch might be broken causing the dishwasher to overfill.

When working as it should the float will lift up as the water rises until it reaches the highest fill level. The tag of the float will then operate the switch. A blockage or breakage could be your issues.

Checking the switch will require electrical equipment although it may be noticeably broken in which case getting a new one should stop the leak.

Alternative Components that May Lead to Leakage

A damaged wash arm or support might force water under the door resulting in leakage. This will also often affect how well your dishes are being cleaned.
