If the leak is intermittent the fault may be as easy as a big pan or another object pushing into the door thus preventing it from sealing fully.

On the other hand the door seal could have come loose or been cracked.

Leaking Hoses

Your dishwasher uses hoses to fill, drain and recirculate water within the program.

Two issues might arise where hoses are involved.

  2. The alternative issue than can easily develop over time is that hoses can become damaged or cracked.

Luckily broken hoses are relatively easy to procure and replace.

Pumps and Seals

You can visually check the rubber gaskets around the pumps or motor to ascertain if there is a leakage and also replace them if that’s the case.

The Float Switch

The float itself or the float switch could be damaged causing the dishwasher to overfill.

A working float will lift up with the water level until the desired or maximum water level is reached. The tail of the float will then turn on the switch. If something is blocking this or the float is broken this could be your issues.
