Why Does My Electrolux Washing Machine Smell Bad?
Run an empty hot wash (60°C or higher) with a washing machine cleaner tablet or 250ml of white vinegar placed directly in the drum — this kills odour-causing bacteria and mould in most cases (takes about 15 minutes of hands-on time, plus the wash cycle).
Fault description
A bad smell coming from your Electrolux washing machine is one of the most common complaints homeowners report, and the good news is that it is almost always caused by something you can fix yourself without any tools. The odour is typically described as musty, damp, or mildew-like, and it often becomes noticeable when you open the door, during a wash cycle, or on clothes straight out of the machine.
The smell originates from bacteria, mould, and soap residue that build up in warm, damp areas of the machine — most often the door seal, the detergent drawer, and the drum itself. Front-loading machines are particularly prone to this because the door seal creates a tight, moisture-trapping environment. If left untreated, the problem tends to get worse over time and the odour can become embedded in laundry.
This guide walks you through the most likely causes and the practical steps to eliminate the smell and stop it coming back.
Causes
- Mould and mildew on the door seal — The rubber gasket around the door of a front-loader traps water, lint, and detergent residue after every wash. This warm, damp environment is ideal for mould and mildew to grow, and it is the single most common source of bad smells in Electrolux washing machines.
- Detergent and fabric softener build-up — Using too much detergent, or using non-HE (high-efficiency) detergent in a modern low-water machine, leaves a sticky residue inside the drum and pipes. This residue feeds bacteria and produces a sour or rancid smell over time.
- Blocked or dirty drain pump filter — The drain pump filter catches lint, coins, and debris before they reach the pump. If it is not cleaned regularly, trapped organic matter decomposes and creates a foul, drains-like odour that can fill the drum.
- Dirty or blocked detergent drawer — Fabric softener in particular tends to congeal in the detergent drawer compartment, creating a thick, smelly residue. Mould can grow here quickly if the drawer is never removed and cleaned.
- Low-temperature washing habits — Washing everything at 30°C or 40°C is energy-efficient, but it does not get hot enough to kill bacteria inside the machine. Over time, bacterial colonies build up in the drum and hoses, producing persistent odours.
- Machine left closed between washes — Keeping the door and detergent drawer shut after a wash traps residual moisture inside, accelerating mould growth. Even a well-maintained machine will develop a smell if it is never allowed to dry out between uses.
Step-by-Step Fix
- 1
Clean the door seal thoroughly
Pull back the rubber door gasket and inspect the fold all the way around. Use a damp cloth soaked in a solution of equal parts white vinegar and warm water to wipe away any visible mould, grime, or residue. For stubborn black mould spots, apply a small amount of bicarbonate of soda paste, leave for 10 minutes, then scrub gently with an old toothbrush and rinse clean.
- 2
Remove and clean the detergent drawer
Most Electrolux detergent drawers release by pressing a small tab or lever inside the drawer — check your model's manual if it does not pull straight out. Soak the drawer in warm soapy water for 15 minutes, then scrub all compartments with a brush to remove congealed softener and mould. Also clean inside the drawer housing in the machine using a damp cloth.
- 3
Clean the drain pump filter
The filter is usually located behind a small panel at the bottom front of the machine. Place a shallow tray and some towels underneath before opening it, as water will spill out. Unscrew the filter cap slowly, let the water drain, then remove the filter and rinse it under a tap, removing all lint and debris. Refit it firmly to avoid leaks.
- 4
Run a hot maintenance wash
With the drum empty, run a full cycle at 60°C or 90°C using either a proprietary washing machine cleaner (follow the packet instructions) or 250ml of white vinegar poured directly into the drum. This kills bacteria and dissolves residue in the drum, hoses, and internal components that you cannot reach by hand.
- 5
Wipe down the drum interior
After the hot wash cycle finishes, wipe the inside of the drum with a dry microfibre cloth to remove any loosened residue. Pay attention to the holes in the drum wall, as residue can collect around their edges. Leave the door open for at least an hour to allow the drum to dry completely.
- 6
Check the standpipe and drain hose
If the smell has a sewage-like quality rather than a mouldy one, the source may be outside the machine. Check that the drain hose is not pushed too far into the standpipe — it should sit no more than 15cm inside and should not be sealed airtight, as this can allow sewer gases to be siphoned back into the machine.
- 7
Adjust your detergent usage and wash habits going forward
Switch to a high-efficiency (HE) detergent if you are not already using one, and use the amount recommended on the packaging — more detergent does not mean cleaner clothes. Run a 60°C wash at least once a month and leave the door and detergent drawer slightly open after every wash to allow moisture to escape.
When to call a service technician
If you have completed all the steps above and the smell persists, there may be a blockage deeper in the drain hose or pump housing that you cannot access without dismantling the machine. A persistent sewage smell that does not improve after checking the standpipe connection can also indicate a fault with the pressure chamber or internal hoses.
You should also contact a service technician if you notice standing water that is not draining, if the machine produces a burning smell (which is a separate and more urgent fault), or if mould has penetrated the drum bearings area and is beyond surface cleaning. A technician can also descale internal components and inspect the heating element, which can harbour bacteria if it is coated in limescale.
Prevention
The parts most commonly replaced in connection with persistent bad smells on Electrolux washing machines are the door seal (gasket), which can harbour mould so deeply it cannot be cleaned, the detergent drawer assembly, and the drain pump filter housing if it has cracked or become impossible to clean properly. Replacing the door seal is a straightforward job that many homeowners tackle themselves with basic tools.

Frequently Asked Questions
How often should I clean my Electrolux washing machine to prevent smells?
A monthly maintenance hot wash at 60°C or above is enough for most households. If you do a lot of low-temperature washing or wash sports kit and heavily soiled items regularly, consider running a cleaning cycle every two to three weeks. Wiping the door seal and leaving the door ajar after every wash makes a significant difference between monthly cleans.
Can I use bleach to clean the inside of my washing machine?
A diluted bleach solution (one part bleach to ten parts water) can be effective at killing mould on the door seal, but use it sparingly and rinse thoroughly afterwards. Do not pour neat bleach into the drum or detergent drawer, as it can damage rubber components over time. White vinegar and proprietary washing machine cleaners are gentler and work well for routine maintenance.
Why do my clothes still smell after washing even though the machine seems clean?
If clothes come out smelling musty, the most likely cause is that laundry is being left in the drum too long after the cycle ends — bacteria multiply quickly in damp fabric. Try to transfer laundry to the dryer or washing line within 30 minutes of the cycle finishing. Also check that you are not overloading the machine, as clothes in an overfull drum do not rinse properly.
Is the bad smell harmful to my family or clothes?
The mould and bacteria responsible for washing machine odours are generally not dangerous to healthy adults, but they can aggravate allergies or asthma in sensitive individuals. The smell itself can transfer to laundry and is unpleasant, but it is not a sign of a safety hazard. Addressing it promptly prevents it from becoming more deeply embedded in the machine.
Why does my front-loader smell worse than a top-loader would?
Front-loading machines use much less water than top-loaders, which means detergent residue is less thoroughly rinsed away. The horizontal door seal also creates a deep fold that traps water and debris after every cycle. These design features make front-loaders more efficient but also more prone to odour build-up, which is why regular cleaning and leaving the door open are especially important for this machine type.
