How to Clean Your Diswasher’s Interior

Use a dishwasher cleaner to remove limescale and grease build-up. Doing so will help maintain your dishwasher’s performance. We recommend using Finish® dishwasher cleaners which can be purchased at your local supermarket.

Finish® Liquid Dishwasher Cleaner - Use this to clean the interior including parts that are hard to reach. Simply follow the instructions on the bottle to clean your dishwasher.

Finish® In-Wash Dishwasher Cleaner Tabs - Use these tabs when you need a more convenient dishwasher cleaner. With these tabs, you won't have to run an empty wash cycle. Simply follow the instructions on the packaging to clean your dishwasher.

How to Clean the Filter

Clean the filter every one to four months depending on usage and after washing loads with large amounts of food soils and starch. This will help your dishwasher maintain optimal performance. The filter is located on the bottom of the dishwasher. Follow the steps below to clean it:

1. Unscrew the filter.
2. Disassemble the filter and rinse it under running water. Use a soft brush to help remove the debris.
3. Reassemble the filter and place it back on the bottom of the dishwasher. Make sure to lock it in place.

For a guided tutorial on cleaning the filter, simply watch the video on the left.

How to Clean the Spray Arms

Limescale can block the nozzles on the spray arms and prevent your dishwasher from cleaning well. If you notice the nozzles are blocked, follow these cleaning instructions:

1. Remove the spray arms. The bottom spray arm is located on the bottom of the dishwasher. The upper spray arm is located beneath the upper rack.
2. Wash the arms under running water. Use a toothpick to poke through the nozzles to remove any trapped debris.
3. Reinstall the spray arms.

For a guided tutorial on cleaning the spray arms, simply watch the video on the right.
