Odour guide
Dishwasher Odour
Dishwasher smells commonly come from food debris, filters, standing water, drain routing or infrequent cleaning.
Safe starting points
- Clean the user-removable filter/sump area as the manual allows.
- Check spray arms and visible food debris.
- Run the manufacturer-recommended cleaning programme/product.
- Confirm the drain hose/high loop/air-gap arrangement follows local installation instructions.
What to do next
A sewage odour can originate in plumbing rather than the dishwasher itself. Persistent standing water or backflow deserves investigation.
