Dont have a garbage disposal? Check your sinks air gap, which prevents drain water from the sink from backing up into the dishwasher. The air gap is a small, slotted cylinder that typically juts up near the faucet, though some may be below the sink near the dishwasher outlet hose. Take the following steps:

  • Clean out any debris with a stiff brush.
  • Replace the cleaned-out sink gap and try running the dishwasher again.

Remove Any Standing Water In The Dishwasher

Jake Romano, plumbing expert and manager of John The Plumber , explains that the first thing you need to do is ‘confirm that the drain the dishwasher connects to is working. The dishwasher will likely connect to the drain under the kitchen sink, so you can test the drain by pouring water into the kitchen sink.’ If your kitchen drain is blocked, you are in luck in the sense that you probably don’t need to do anything to the dishwasher itself, just clear the drain.

The Filters Are Dirty

If your dishwasher wont drain, the first thing you should do is check your filter. Filters are an integral part of a dishwasher and need to be maintained to keep the machine running efficiently. Filters trap soggy food particles and prevent excess food and grease from being redeposited within the dishwasher.

However, filters can easily become blocked if they are not regularly cleaned. We recommend cleaning your dishwasher filters at least once a fortnight to avoid dirty plates and ensure your appliances longevity. Luckily, cleaning your filters is a simple enough task.

Firstly, youll need to locate and remove your filters. These are found at the bottom of the dishwasher, below the lower spray arm. Begin by twisting the cylindrical filter to release the filter from the dishwasher.

Once the cylindrical filter has been removed, it is then possible to lift the metal mesh filter plate. Have a quick look in the sump, the lower pit located underneath both filters, to check that no large food deposits have fallen into the sump area and are causing a blockage.

To clean the filters, youll need to run them under the tap to wash away any food deposits or built-up grease. For extra tough grime, you may want to use hot soapy water with a sponge or even an old toothbrush. Simply replace the filters within the dishwasher once they are clean and grime-free.

Clean Out the Filter
