If your dishwasher has developed a bad smell, don’t worry. This is a common problem that can be resolved with simple measures. The list below details the most common causes of the issue and advice on how to act.
Dishwasher smells bad

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 odor-free. If not properly maintained, odours can build up in your appliance, especially around the areas which are made of plastic. To find out more on how to clean your dishwasher effectively, click here.

Blocked 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. For a step by step guide on how to unblock your dishwasher filter, click here.
Kinked or damaged connection
If the dishwasher hose is kinked or bent, the waste water will not be pumped away and will flow back into the dishwasher. Inspect the hose carefully and be sure to straighten out any visible kinks. You can purchase a replacement hose using our spare parts search and entering the appliance information to get the bill of materials or by calling customer service on +356 2546 4543, where a member of our customer service team will assist your further with your query.
