Quick answer
Read your washer's manual, empty and isolate the machine, then clean the dispenser, door gasket, accessible filter and tub before running the approved cleaning cycle. Leave the door or lid and drawer open to dry, and use bleach, vinegar or a commercial cleaner only when your model's instructions allow it—never mix them.
A washing machine can look clean while detergent residue, lint, hair, mineral deposits and trapped water collect in the parts you rarely see. A sour smell may come from a damp door gasket or dispenser, while poor draining can point to a pump filter or hose problem rather than a dirty drum.
The safest method is not to pour a random kitchen chemical into the tub. Start with the owner’s manual, clean the accessible parts, then run the cycle and product your model approves. Front-load and top-load washers do not have identical filters, gaskets or cleaning programs; the manufacturer’s instructions take priority over any generic tip.
1. Identify the washer and read the manual
Find the model number on the door frame, control panel, rear label or inside the lid. Look up the care instructions and check five things before removing anything:
- whether the washer has a Clean Washer, Self Clean or Basket Clean cycle;
- whether bleach, vinegar, a tablet or a branded washer cleaner is approved;
- how to remove the dispenser and, on some front-loaders, the pump filter;
- whether the gasket or tub has a special finish; and
- whether the machine needs a separate rinse after its cleaning cycle.
Samsung’s washer-cleaning guide separates front-load and top-load maintenance, while GE publishes different tub procedures for its two designs. Treat those pages as examples of model-specific instructions, not as permission to copy a dose into another brand.
2. Empty, cool and isolate the machine
Remove every garment, pod, detergent container and loose object. If the washer has just run, wait until the water and surfaces are cool. Turn it off and follow the manual’s power-isolation instructions before reaching near the pump, filter, cord or other electrical parts.
Put an old towel on the floor. Wear gloves if you are handling stagnant water, lint or cleaning product, and ventilate the room. Do not clean around a damaged cord, exposed wiring, burning smell or active leak; arrange service instead.
3. Wipe the exterior, lid and control area
Start with the easy soil. Use a soft, damp microfibre cloth on the top, lid or door, detergent drips, control surround and cabinet. Put cleaner on the cloth rather than spraying into buttons, vents, seams or the door latch. Dry the surface afterward so water does not sit around the controls.
4. Remove and wash the detergent drawer
Pull out the dispenser only as the manual shows. Flush each compartment with warm water and use a soft brush for dried detergent, softener or lint around the siphon openings. Samsung specifically recommends warm-water rinsing and a soft brush for residue in its drawer-cleaning instructions.
Clean the drawer opening as well; a clean drawer can still smell if sludge remains behind it. Rinse until the water runs clear, dry the pieces and replace them in the correct orientation. Do not use a knife to dig out buildup or pour a strong chemical into a narrow siphon. If the drawer will not release, look up the model procedure instead of forcing it.
5. Clean a front-load door gasket gently
Open the door and inspect the entire rubber seal, including the folds at the bottom. Remove hair, coins, tissues and lint by hand or with a soft cloth. Wipe the accessible rubber with warm water and the mild, manufacturer-approved cleaner, then wipe again with clean water and dry every fold.
Do not stretch, cut or scrub the gasket with steel wool. Avoid harsh or abrasive cleaners unless the manual specifically names one. A torn, permanently folded or foul-smelling seal may need replacement rather than more cleaning. Leave the door ajar after each load so the interior can dry; Samsung and Maytag both describe ventilation and an open door as part of washer care.
Top-loaders do not have this door gasket, but check under the lid, around the tub rim and near the agitator or impeller for detergent film and trapped lint.
6. Inspect the pump filter if your model has one
Some front-load washers have a user-accessible drain-pump filter; others use a different design or hide service parts behind a panel. Follow the manual exactly. Put a shallow pan and several towels below the access point before opening it because residual water may drain out.
Remove lint, hair, buttons and other debris, rinse the filter with warm water and inspect its seal. Refit it firmly without cross-threading or forcing the cap. Never put fingers into an unseen pump, remove a cover that the manual does not identify or run the washer with a filter incorrectly installed.
If the washer still will not drain, repeatedly shows a drain error or returns dirty water, the problem may be a hose, pump or installation issue. The drain-unclogging guide covers household plumbing separately, but an appliance fault needs the manual or qualified service.
7. Clean the tub and agitator area
Wipe accessible residue from the tub rim, lid underside, agitator or impeller with a soft cloth. For a top-loader, look for film under the rim and around the dispenser. For a front-loader, do not pour water into the control panel, detergent drawer cavity or door seal.
Do not assume that a full load of hot water is a cleaning cycle. A washer’s dedicated program may use a different water level, temperature or motion. GE’s front-load guidance and top-load guidance show why the correct process depends on the design.
8. Run only an approved cleaning cycle
With the washer empty, select its Clean Washer, Self Clean or Basket Clean program if it has one. Add only the product and amount listed in the manual. Some GE guidance allows one cup of liquid bleach or a washing-machine cleaner for particular tub-clean procedures; another model may require a tablet or a different product. Do not treat a manufacturer’s dose as universal.
Maytag says its Clean Washer cycle may use an approved washer cleaner, liquid chlorine bleach or another specified product, and recommends monthly use for many models. That is a maintenance example, not a replacement for your own manual.
Never combine products. In particular, bleach mixed with an acid such as vinegar can form chlorine gas, and bleach mixed with ammonia can form chloramine gas. Poison Control’s chlorine-gas guidance explains the hazard. If you accidentally create strong fumes, leave the area for fresh air and contact local emergency or poison-control services as appropriate.
9. Rinse and dry the machine completely
Run the additional rinse or empty cycle specified by the manufacturer. Do not add a second chemical to “neutralise” the first one. When the cycle ends, wipe away loosened residue from the door, rim or tub and leave the door or lid open.
Pull the detergent drawer open so air can reach the cavity. Remove standing water from the gasket folds and wipe the cabinet dry. A washer that stays closed and wet between loads is more likely to develop a recurring smell. If you use a cleaning product, store it closed and away from children and pets.
10. Test the washer and set a realistic rhythm
Run a short empty rinse or the test procedure in the manual. Watch for leaks, unusual noise, a drain error, dirty water, excessive suds or a door that will not lock. Stop using the machine if any warning persists.
As a starting rhythm, inspect the gasket and drawer whenever you see residue, clean the accessible pump filter on the manual’s schedule and run the approved tub-clean cycle as directed. GE and Maytag both publish monthly examples, while Samsung describes routine and monthly cleaning for its washers. Usage, water hardness and the model design all change the interval.
Use this quick diagnosis table after cleaning:
| Symptom | First check |
|---|---|
| Sour or musty smell | Gasket folds, drawer cavity, standing water and air circulation |
| Washer will not drain | User-serviceable filter, drain hose and the manual’s error procedure |
| White or slimy residue | Detergent dose, drawer siphon, water hardness and approved cycle |
| Excessive suds | Wrong detergent, too much detergent or an unapproved cleaner |
| Odor returns quickly | Moisture source, damaged seal, drain installation or inaccessible buildup |
If a visible mold problem continues, fix the moisture source instead of repeatedly masking the smell. The EPA’s mold guidance says moisture control is central and that bleach is not a routine answer for mold cleanup. Persistent mold inside an inaccessible washer area, a damaged gasket, electrical fault or contaminated pump is a service problem.
For another appliance-care project, the dishwasher-cleaning guide uses the same useful rule: read the manual, clean the parts that catch residue and never assume that a stronger chemical is a better maintenance plan.

Frequently Asked Questions
How often should you clean a washing machine?
Follow your model's manual. GE and Maytag give monthly tub or Clean Washer guidance for many machines, while a washer used heavily, with hard water or with persistent odor may need attention sooner. Wipe visible residue and the gasket whenever it appears, rather than waiting for a calendar date.
Can you clean a washing machine with vinegar?
Only if your washer's instructions explicitly allow it. Some GE top-load guidance allows vinegar in a Basket Clean cycle, but that is not a universal rule. Never combine vinegar with bleach, ammonia or another cleaner, and do not use a homemade mixture in an unapproved machine.
How do you clean mold from a washing machine gasket?
Follow the manual, then wipe accessible residue from the gasket with a soft cloth and the approved mild cleaner, rinse and dry the folds completely. If mold, odor or water remains in an inaccessible area, stop improvising and contact the manufacturer or a qualified technician.
Do you need to clean a washing machine filter?
Only when your model has a user-serviceable filter or pump filter and the manual provides the procedure. Front-load machines may leave water behind the filter, so prepare a shallow pan and towel, isolate the machine and never force a cover or reach into an unseen pump.
