There is a bad smell coming from the dishwasher
To see what each step looks like, just click each step and check out the picture. You can also use the arrow keys on your keyboard.
This can be caused by using the dishwasher at a low wash temperature for a prolonged period of time. Try using a high temperature wash programme at least once a month (e.g. Intensive Wash — P4).For more information see the Dishwasher programmes topic.
Check the dishwasher door seals for old food residue.
