Use the washer's reminder or manual as the controlling interval. Run the dedicated cycle empty with only the approved cleaner; odor, residue, frequent cold washes or heavy detergent use can justify earlier cleaning. First, read the cycle label and approved cleaner quantity for the exact model.

ReversibleRead the cycle label and approved cleaner quantity for the exact model.
Separate the fault or decision boundary
ReversibleCorrect overdosing, wrong detergent, wet gasket/dispenser and slow drainage so buildup does not immediately return.
Apply the narrowest correction
ReversibleRun the dedicated cycle empty, then wipe and dry accessible surfaces.
Read the cycle's label and the cleaner amount in the manual
ReversibleFind the tub-clean or drum-clean cycle in the manual for your exact model, along with the approved cleaner and the quantity. Using the wrong product or too much can leave residue or damage seals.
Fix the causes of build-up so it does not return quickly
ReversibleReduce detergent overdosing, use high-efficiency detergent in a high-efficiency machine, wipe the gasket and dispenser, and leave the door ajar so the drum can dry. These prevent most odors.
Run the cycle empty, then wipe and dry the surfaces
ReversibleStart the cleaning cycle with an empty drum and the approved cleaner only. Afterwards wipe the gasket, the drawer and the door glass, and run a rinse to check that no cleaner residue remains.
Count washes, not just weeks
ReversibleWhirlpool's rule is whichever comes first, one month or 30 washes. A household that runs a wash a day reaches 30 washes before the month is over, so it should clean more often than the calendar suggests.
Remove all laundry and add the cleaner the way the label says
ReversibleEmpty the drum completely. Place the affresh tablet at the bottom of the basket, not in the dispenser, or measure no more than 1 cup of plain liquid chlorine bleach into the compartment. Add no detergent.
Let the cycle finish, then leave the door or lid open
ReversibleDo not interrupt the cycle. When it ends leave the door or lid open so the drum dries; a closed, damp drum is what brings the odor back.
Verify before escalating
ReversibleConfirm the drum is empty of cleaner residue and the next rinse drains normally.
By brand
The interval each maker gives
The manual's interval controls; these are the published figures for the brands that document one.
- Whirlpool, Maytag and affresh
- Run the Clean Washer cycle every month or every 30 wash cycles, whichever comes first. The affresh tablet goes at the bottom of the basket, never in the detergent dispenser; the alternative is no more than 1 cup of plain liquid chlorine bleach in the compartment. Thickened, easy-pour or no-splash bleach is not to be used, and no detergent is added.
- Samsung Self Clean
- The reminder LED comes on after 20 washes on a top-load model or 40 on a front-load model, and Samsung says to run it at least once a month if you do few washes. No cleaner is needed for Self Clean; Samsung recommends bleach only where a mold smell already exists.
- Front-load versus top-load
- Whirlpool's guidance is the same for both: a monthly cycle plus leaving the lid or door open afterwards, HE detergent at the recommended amount and an occasional warm or hot wash rather than exclusively cold.
Stop boundary
When this stops being a self-service repair
- !Never mix bleach with vinegar, ammonia, acids or unknown cleaners, and do not run the cycle with clothes inside.

Exact questions
Common questions about “How often should a washer tub-clean cycle be run?”
How often should I clean my washing machine?+
Follow the machine's reminder or the manual, commonly once a month or every 30 to 60 cycles. Clean sooner if there is an odor or residue.
Can I use bleach in the tub-clean cycle?+
Only if the manual says so. Some makers specify their own cleaner, and mixing bleach with other products is dangerous.
Why does my washer smell even after cleaning?+
The gasket, dispenser or drain may still hold residue. Wipe those, check the drain hose and leave the door open between washes.
Do front-loaders need cleaning more than top-loaders?+
They tend to trap moisture in the gasket, so they benefit from wiping and airing, but both need the cycle now and then.
What if the display shows a Clean Washer reminder?+
Samsung's Self Clean reminder LED appears after 20 washes on a top-load model or 40 washes on a front-load model. It is the manual's own count, so run the cycle when it lights.
Can I use more bleach to be safe?+
No. Whirlpool warns that more than 1 cup of liquid chlorine bleach could cause washer damage, and that thickened, easy-pour or no-splash bleach must not be used.
Why does an occasional hot wash matter?+
Whirlpool advises using warm or hot water sometimes rather than only cold, because cold washes leave more detergent and body-oil residue in the drum and gasket.
Does every washer have a tub-clean cycle?+
Many front-load and high-efficiency models do. If yours does not, the manual will describe a hot cycle with a suitable washer cleaner.
Should I use detergent for a tub clean?+
Use only what the manual specifies, usually a washer-cleaning tablet or nothing at all. Extra detergent can create suds.
