Washing Machine Smells Bad How to Clean It in Ashton-under-Lyne

Published October 2026 | Washing machine smells bad how to clean it

If your washing machine smells of burning, hot plastic, or scorched rubber, switch it off at the wall socket immediately and do not use it again until a qualified engineer has inspected it - this is a potential electrical fault and a fire risk.

Immediate Actions - Do These NOW

The right first move depends entirely on what your washing machine actually smells like. Different smells point to very different problems, and treating a drainage issue the same way you'd treat an electrical fault is a mistake. Here's how to read the smell and act straight away.

If it smells of burning, hot plastic, or scorched rubber: Switch the machine off at the plug socket - not just the power button on the front panel. Unplug it from the wall if you can do so safely. Don't run another cycle to "see if it happens again." A burning smell almost always means a motor, drive belt, or wiring issue that could become a fire hazard if ignored. Get an engineer out before the machine is used again.

If it smells like rotten eggs or an outside drain: This is typically a drainage problem rather than a fault with the machine's mechanics. Sewage-type odours can travel back through drain connections where the hose isn't properly sealed into the standpipe. Severn Trent Water's guidance on sewage odours notes that household drain cleaning products can help where the smell originates in the drainage connection itself - but if the smell persists after that, you need an engineer to check the machine's drain hose and pump filter properly.

If it smells musty, damp, or like mildew: This is by far the most common scenario we see in Ashton-under-Lyne, and while it's not a fire-risk emergency, you should act today before the smell works its way into your laundry permanently. Do the following in order:

  1. Pull back the rubber door seal and inspect inside the folds carefully. Wipe it down with a cloth dampened in a 50/50 solution of white vinegar and warm water. On most Bosch, Hotpoint, and Beko machines, you'll find black mould concentrated in the bottom fold of the seal.
  2. Remove the detergent drawer completely - it slides out on most machines. Wash it under a hot tap and scrub any black or slimy residue from the drawer housing itself using an old toothbrush. The housing cavity is a classic mould trap.
  3. Locate and clean the pump filter. On most front-loaders - including Samsung, LG, and Beko models - it's behind a small access panel at the bottom front of the machine. Lay a towel down first, open the filter cap very slowly to let trapped water drain, then remove and rinse the filter under the tap. The debris you find in there is usually part of what's causing the smell.
  4. Run a hot maintenance wash with the drum completely empty. Use the 90-degree cycle if your machine has one, or the highest temperature available. Pour 500ml of white vinegar directly into the drum - no detergent. This kills the bacteria causing the mildew smell and rinses away detergent residue at the same time.

Many homeowners in Ashton-under-Lyne find these four steps are enough to clear a musty smell entirely, especially if it's caught early. If the smell is still there after two cleaning cycles, there's likely a partial blockage deeper in the system that needs professional attention.

What NOT to Do (Common Dangerous Mistakes)

There are a handful of things people commonly try when a washing machine smells bad that either don't work or actively make things worse.

Don't run another cycle when there's a burning smell. Our engineers across Greater Manchester regularly attend callouts where homeowners have done exactly this, hoping the smell would clear itself. Continuing to run a machine with an electrical fault risks burning out the motor entirely, turning what could have been a 150-pound repair into a 300-pound one - or worse, causing a fire.

Don't pour bleach directly onto rubber door seals. Bleach will degrade the rubber over time, causing it to crack and eventually leak. You'll end up with a water-damaged floor and a repair bill on top of the original smell problem. A diluted bleach solution in the detergent drawer on a hot cycle is acceptable occasionally, but keep it away from the seal itself.

Don't load up on extra detergent to try and mask the smell. Excess detergent residue is one of the primary causes of mould and mildew build-up in the first place. Modern concentrated detergents - including the pods and gel capsules used in most Ashton-under-Lyne households - need much less product than older powder formulas. LG and Samsung both advise using significantly less than the maximum marked on the dispenser. More detergent means more residue, which means more smell.

Don't close the door tightly after every wash. A sealed drum full of residual moisture is exactly the environment mould and mildew need to thrive. Always leave the door ajar between washes, and if possible, leave the detergent drawer slightly open as well to let air circulate.

Don't assume a sewage-type smell will resolve itself. A persistent drain smell means something is wrong with how waste water is leaving the machine. Running more cycles with that fault in place can back water into the drum or cause localised flooding. It needs investigating.

When This Is a Genuine Emergency vs When It Can Wait

Not every bad smell from a washing machine is a crisis. Knowing which situation you're actually in saves you both money and stress.

Stop using the machine immediately if:

In these situations you're either dealing with an electrical fault or a plumbing problem that risks water damage. Both need an engineer before the machine is used again.

It can wait 24-48 hours (but don't ignore it) if:

In these cases, start the self-cleaning steps outlined above and monitor for improvement. If the smell doesn't shift after two proper cleaning cycles, book a service visit - it's likely a partial blockage that needs a professional clear-out rather than a surface clean.

Getting Emergency Help in Ashton-under-Lyne

If you're in Ashton-under-Lyne and your machine has developed a burning smell, is failing to drain, or has tripped your electrics, you need an appliance repair engineer who knows the area and can respond quickly. Most reputable local engineers covering the Greater Manchester area will be able to tell you on the phone whether your symptoms sound urgent before committing to a call-out time.

When booking through Voltrade, the GoFIX diagnostic tool can help identify the most likely fault causes before an engineer arrives on site. That means less time spent diagnosing during the visit itself and a faster resolution - which matters when you've got a machine full of laundry and no alternative.

When you're contacting any repair engineer in Ashton-under-Lyne, ask these three things upfront:

For machines with a burning smell or electrical fault, don't attempt any internal inspection yourself. Washing machines run on 240V mains supply, and internal components can hold charge even when unplugged. Leave that to the engineer.

What the Emergency Repair Involves

When an engineer arrives to inspect a smelly or suspected-faulty washing machine, here's what you can typically expect the visit to involve.

Initial diagnosis. The engineer will run the machine through a cycle while checking the drum, filter, door seal, drain hose, and pump for signs of blockage or damage. If there's been a burning smell, they'll inspect the motor, drive belt, and wiring for heat damage or failure.

Filter and pump clear-out. In a significant number of callouts across Greater Manchester, a blocked pump filter or a kinked drain hose is the root cause of both the smell and any drainage problems. A professional clear-out of the pump and filter typically takes 20-30 minutes and often resolves the issue completely without any parts being needed.

Door seal inspection and possible replacement. If mould has penetrated the seal itself rather than just sitting on the surface, cleaning won't solve the problem - the seal needs replacing. A replacement door gasket on a Hotpoint or Beko machine typically costs between 40 and 80 pounds for the part, with labour on top.

Heater element and drum inspection. Machines that have been running primarily on low-temperature cycles for an extended period can develop significant limescale and detergent residue on the heater element. This affects washing efficiency as well as contributing to bad smells. A descale or element replacement may be recommended depending on the condition.

Typical costs in Ashton-under-Lyne. A call-out and first hour of labour commonly runs between 60 and 100 pounds. A full repair involving a replacement pump or door seal typically comes to between 120 and 220 pounds including parts. If a motor has burned out, total costs can reach 250 to 380 pounds - at which point it's worth weighing up the cost of a new machine, particularly for appliances that are more than eight to ten years old.

Emergency Questions

Why does my washing machine smell like rotten eggs?

A rotten egg or sulphur smell from your washing machine almost always points to a drainage issue. Bacteria thrive in stagnant water trapped in the pump filter, drain hose, or standpipe connection. Severn Trent Water's guidance on sewage odours notes that household drain cleaning products can clear the issue when it originates in the drain connection itself. If the smell persists after that, a blocked pump filter or an improperly fitted drain hose is the most likely cause and warrants a professional inspection.

How often should I clean my washing machine to stop it smelling?

Most appliance engineers recommend a hot maintenance wash once a month as a minimum, with the drum empty and white vinegar or a proprietary cleaner tablet added directly. Clean the pump filter every two to three months - more often if you wash heavily soiled items regularly. Wipe down the door seal and detergent drawer every couple of weeks. If you're in a hard water area, which covers much of Greater Manchester, a dedicated descaling treatment every few months also helps prevent limescale build-up on the heater element.

Is it safe to keep using a washing machine that smells musty?

A musty or mildewy smell with no other symptoms - no burning, no drainage failure, no tripped electrics - is generally not a safety issue in the immediate term, but it's not something to keep ignoring. The mould causing that smell will eventually transfer to your laundry, and the underlying build-up that's causing it can eventually affect the machine's pump or heater element if left long enough. Clean it now, and if the smell doesn't clear within two cycles, book a service.

My machine smells fine when empty but my clothes come out smelling bad - what's happening?

This is typically caused by using too much detergent - particularly gel capsules - combined with regular low-temperature washing. The detergent doesn't rinse out fully and deposits residue into the fabric itself. Try cutting your detergent quantity roughly in half, run a 60-degree cycle, and avoid overpacking the drum so water can circulate properly. If the problem continues after a couple of washes, book a service - there may be residue build-up in the drum paddles or inside the drum itself that needs a professional clean to shift.
