Run a maintenance wash
Soiled filter
Use rinse program with higher temperature

Step 1: Run a maintenance wash.

We recommend that you carry out a maintenance wash every 4-6 months depending on how often you use your appliance. A maintenance wash will help your appliance function effectively and odour-free. If not properly maintained, odours can build up in your appliance, especially around the areas which are made of plastic.

Step 1

Unload your dishwasher. We recommend cleaning your appliance right after you have ran a cycle since this means you will have clean crockery and cutlery ready to use.

Step 2

Check that the filter is not blocked with food remnants or other objects. Be sure to use protective gloves in case you find any sharp objects, such as glass fragments.

Step 4

Pause the cycle after 30 Minutes and add the Dishwasher Maintenance Cleaning Powder contents by carefully opening the dishwasher door and emptying the contents inside until the box is empty.

Step 5

Restart the programme and let it run until completion.

Step 2: Soiled filter.

Be sure to check that your dishwasher filter isn’t blocked . This can often be the reason why the appliance starts to develop unpleasant odours, as food may be stuck inside the appliance and waste water will not be pumped out effectively. This will lead to ineffective wash cycles and an unpleasant smell inside the machine.
