Why Is My Dishwasher Not Cleaning Properly?

There are several reasons why your dishwasher may not be cleaning your dishes properly. It is important to rectify this common issue on your appliance promptly to make sure your crockery is cleaned correctly, ensuring excellent hygiene results. If your dishwasher isn’t cleaning properly and you’re noticing unpleasant smells, see our dishwasher odour help page.

Common reasons why your dishwasher is not cleaning well & solutions

1. Blocked Filter. To ensure your dishwasher is performing at maximum efficiency, it is important to regularly clean your appliance’s filter. In doing so, you can ensure your appliance delivers excellent cleaning results. For easy-to follow instructions and videos that explain how to clean your appliance’s filter, please read our dedicated guide on how to clean a dishwasher.
2. Blocked Spray Arm. If you find that your dishwasher is not rinsing your dishes, it may be that the appliance’s spray arm is blocked. To rectify this, remove the spray arm and rinse under a tap to clear any blocked nozzles. The above guide on cleaning your dishwasher offers more advice on carrying out this work.
3. Low water temperature. To remove germs from household items, water needs to reach a temperature above 65°C.[1] A high temperature is also needed to dissolve excess food and remove tough stains. To ensure excellent dishwashing results, it is important to select a wash cycle with a suitable temperature for your dishes.
4. Selecting the correct wash cycle or overloading. Make sure you are using a suitable washing programme for the level of soiling on your dishes, the quantity of dishes you are washing and ensure you aren't overloading your dishwasher. Incorrect stacking can also cause poor washing results. For more information on how to load your dishwasher correctly, please click here.
5. Water hardness. If you are using the dishwasher for the first time, you will need to add 1 litre of water to the dishwasher's salt reservoir and then stir with a spoon. Have you also set the water hardness level for your dishwasher? Take a look at the instruction manual for your machine for more details on how to do this. Can't find it? Don't worry, you can download your manual here.
