The short answer
A Ellipse dishwasher that smells is holding food residue somewhere that stays wet — the filter and sump first, then the door seal and the drain hose. It is a maintenance fault rather than a component failure, and it is made much worse by short cool cycles and by a door that is always closed on a damp tub.
What you are actually seeing
- A stale or sour smell when the door is opened — What it means: residue in the filter and sump, the usual case
- A drain smell that is worse after the machine has stood idle — What it means: the waste connection or a missing high loop, not the machine's interior
- Black or grey film along the door seal — What it means: established growth on the gasket, which transfers odour to every load
- Standing dirty water in the base — What it means: a drain fault, and it must be fixed before any cleaning will hold
Causes, ranked for an Ellipse dishwasher
- Loaded filter and sump — Trapped food sits in the wet sump between cycles and is the single largest source of odour in a dishwasher. — Why this rank: Top of the list because it is where the smell physically is, and the filter is designed to be removed by the owner.
- Short, cool cycles only — Eco and quick programmes never reach a temperature that clears grease from the tub, the arms and the hose. — Why this rank: Second because it is the habit that keeps regrowing whatever you clean out, and correcting it is free.
- Residue on the door seal and edges — Why this rank: Ranked here because these surfaces are outside the wash pattern entirely, so they only ever get clean by hand.
- Drain hose without a high loop — Why this rank: Ranked here because it produces a distinctly drain-like smell that identifies itself.
- Ranking basis: Ranked for this machine because the mechanical parts of this appliance class are near-universal, so they can be diagnosed and sourced without knowing whose platform this is.
What to check, and in what order
- Smell the open tub, then the filter, then the door seal — Step: First — Why here: the strongest source tells you which of three different jobs to do
- Note whether the smell is stale food or drain gas — Step: Second — Why here: stale food is the filter and the seal; drain gas is the hose route and the waste connection
- Check for standing water in the base — Step: Third — Why here: a drain fault must be corrected first, or any cleaning is undone within a day
Checks an owner can safely make
- Note the model and serial from the rating plate, and search by symptom and appliance type rather than by brand name. — Tools: phone camera — Time: ten minutes
- Switch off at the breaker, remove the lower rack and take out the filter assembly. — Tools: gloves — Time: five minutes
- Wash the filter under a hot tap with a brush and detergent until the mesh runs clear, then clear the sump by hand.
- Wipe the door gasket, the lower door edge and the tub lip — the spray never reaches these.
Before you touch anything
Safety
Cleaning is owner work, but the sump hides glass and the products matter. Isolate first, wear gloves, and never combine cleaners. Unplug the appliance or switch off its breaker before removing any panel. A capacitor can hold a charge after the power is off. Never mix a chlorine product with a citric or acid descaler.
Where an owner fix ends and a service call begins
The smell returns within days of a full clean and a hot empty cycle There is standing dirty water in the base, which is a drain fault to fix first The smell is drain gas rather than stale food, which usually means the hose routing or the waste connection
