The answer, first
Mould and smell in an Equator combo come from warm damp organic residue, and they live in four places: the filter, the sump, the door gasket and the flat low point of the drain hose. Deal with all four in one session rather than one at a time, then keep the door ajar between cycles. If it returns quickly, stop cleaning and investigate the drain.
What you are seeing
- Black or pink film in the gasket channel and around the door edge — Biofilm in the place that is warm, damp and never scrubbed.
- Smell that transfers onto clean crockery — Soil is being recirculated, which makes this a filter and drain issue.
- A drain-like smell that worsens after the machine stands unused — Stagnating water in the sump or a dry trap at the waste.
- Smell strongest at the start of a cycle — Residue being warmed and re-wetted before it is washed away.
- NEAR MISS: damp joinery smell with no odour inside the tub — That is a leak into the cabinet, covered by the leak page, and it matters more than a smell.
Likely causes in order of odds
- Water not fully draining — Top of the list: water that stays stagnates, and cleaning a machine that cannot empty buys you a few days.
- Filter and sump holding soil — Second: a small filter reaches capacity quickly and then contributes smell and poor results together.
- Biofilm in the door gasket and around the door edge — Third: the gasket channel is warm, damp, organic and never wiped, which is the complete recipe for the black film owners find there.
Check in this order
- Look for standing water at the end of a cycle — Anything more than a film means the drain page is the one to work before cleaning again.
- Lift the filter out and look at the sump underneath — What you find explains the smell and usually the results complaint as well.
- Wipe the gasket channel and the door bottom edge with a cloth — If the cloth comes away grey or black, that is the source you could smell.
Owner-side checks, step by step
- Remove and scrub the filter, then clear the sump — Warm water, brush, gloves.
Tools: gloves, soft brushAbout 25 min
- Wipe the gasket channel and the door bottom edge — A cloth and a cotton bud for the corners where biofilm lives.
Tools: cloth, cotton budAbout 15 min
- Check for standing water at the end and clear the drain path if present — If water stays, the smell will come back whatever you clean.
Tools: glovesAbout 20 min
- STOP HERE if the smell returns within days of a full clean — That pattern means water is being retained or waste gas is entering, and the drain route needs a technician rather than more cleaning.
Safety before diagnosis
Safety
Power off at the breaker before any panel comes off. Unplug the appliance or switch off its breaker before removing any panel, because a capacitor can hold a charge after the power is off. allowlist:unplug-before-service
The line between a fix and a call
Call when a full clean has not held, particularly when the smell returns within days, because that means retained water or waste gas entering the machine rather than residue. Call sooner if the musty smell is in the cabinet around the combo rather than inside it, since that is a leak soaking joinery and it gets more expensive every week.

Generalized information, and where the specifics live
Treat this as generalized information about an Equator combo. It does not claim to describe your exact family or build, because this badge covers several contract-built platforms and they are not wired the same.
