What To Know

  • If the filter is clogged, it can restrict the flow of water and cause the dishwasher to clog.
  • If the drain hose is kinked or blocked, water will not be able to drain from the dishwasher.

A clogged dishwasher can be a frustrating and inconvenient problem. If your dishwasher is not draining properly, it can leave your dishes dirty and your kitchen a mess. But don’t worry, unclogging a dishwasher is a relatively simple task that you can do yourself.

In this guide, we will walk you through the steps on how to clean a clogged dishwasher. We will cover everything from identifying the clog to removing it and preventing future clogs.

Identifying the Clog

The first step to unclogging your dishwasher is to identify the clog. There are a few common places where clogs can occur:

  • The drain hose: The drain hose carries water from the dishwasher to the sink drain. If the drain hose is clogged, water will not be able to drain from the dishwasher.
  • The drain pump: The drain pump is responsible for pumping water out of the dishwasher. If the drain pump is clogged, water will not be able to drain from the dishwasher.
  • The filter: The filter traps food particles and other debris from entering the dishwasher’s drain. If the filter is clogged, it can restrict the flow of water and cause the dishwasher to clog.

Removing the Clog

Once you have identified the clog, you can begin to remove it. Here are the steps on how to remove a clog from a dishwasher:

1. Disconnect the dishwasher from the power source.
2. Turn off the water supply to the dishwasher.
