There are some components that could have moisture around them which is one of the reasons why the error code was displayed on your dishwasher. 

Below are some components that might be leaking or damaged.

  • Spray arm – If the spray arm is either clogged or damaged, it can result in inappropriate spraying of water to unusual areas which can eventually cause the water to seep and leak out of the dishwasher. 
  • Water inlet valve – This component mainly controls the flow of water into the appliance. It can cause overfilling and leaks if it gets clogged or faulty. 
  • Door seal and gasket – If the door seal is worn out or has lost its elasticity, it won’t be able to stay tight anymore which can cause gaps and lead to water leaks.
  • Drain, water supply hose & pump – A leak might have occured in any of these drainage system. Most times it can be leaks from a damaged water supply hose or clogged drain hose.


Initially, you need to ensure that there are no dirt or food particles accumulated on the seal.

Excessive moisture buildup can have an adverse effects on the unit, which is why it’s important to replace a damaged water inlet valve if you discover signs of failure.

You should use detergents that are meant for dishwashing only, so that you won’t have to experience what happened to my personal dishwasher when I accidentally used it.

First, proceed to unplug the dishwasher from it’s power source or flip the circuit breaker. Then give the appliance some time to dry.

The time it takes to dry ranges from 30 minutes to 1 hour.

What you have to do is to ensure that the cap or knock-out plug is removed. Once it is, reset your dishwasher and check if the error code has disappeared.
