What you are actually seeing
- A smell that is worse after the machine has stood unused
- A musty smell from the drum when the door is opened
- Black residue in the door seal folds
- Sludge in the dispenser drawer
- Not this fault: A smell with water left in the drum
Ranked causes on a Conservator washer
- Drain hose or standpipe as the source — Ranked here because: these machines are commonly installed by the owner or the delivering dealer, and levelling and venting errors are the most frequent finding
- Biofilm in the door seal folds — Ranked here because: the gasket is the cheapest thing on the machine to get wrong and the easiest to confirm
- Door and drawer kept closed between washes — Ranked here because: a simple machine gives the owner more ways to load and dose it wrong, and those show up as faults
- Pump filter holding debris and standing water — Ranked here because: the pump is the only powered part in the drain path and it takes everything the machine washes off
What to check, and in what order
- Leave the door and the dispenser drawer ajar between washes
- Pull the door seal folds right back and clean them with hot water and a cloth
- Remove the dispenser drawer, wash it and clean the housing above it
- Run the hottest programme on an empty machine with a washing machine cleaner
Steps you can safely do yourself
- Remove the dispenser drawer, wash it and clean the housing above it — Tools: brush, hot water — Estimated time: about twenty minutes
- Run the hottest programme on an empty machine with a washing machine cleaner — Tools: machine cleaner — Estimated time: one full cycle
- Open the drain pump filter, clear it and wipe the housing — Tools: shallow tray, cloth — Estimated time: about half an hour
- Halve the detergent dose and stop using fabric softener for a few weeks — Tools: none — Estimated time: a few cycles
- Leave the door and the dispenser drawer ajar between washes — Tools: none — Estimated time: no extra time — a habit rather than a task

When to call a technician
the smell persists after the seal, the drawer, the filter and a hot maintenance wash the machine is not draining fully, since stale standing water will always come back the smell is a drain smell, which means the waste connection needs correcting
