How to Clean a KitchenAid Washing Machine

KitchenAid packs in premium touches — the ProWash auto-sensing system, a satin-finish drum, and a PrintShield exterior — and each needs its own care. A fouled soil sensor in particular makes ProWash underread dirt and cut cycles short, so cleaning is about performance as much as odor.

Tools and supplies#

• Tools: Phillips #2 screwdriver, Torx T20 driver, a soft-bristle brush, microfiber cloths, a spray bottle
• Supplies: Affresh washer cleaner tablets (W10501250, cross-compatible across Whirlpool Corp brands), white vinegar, baking soda, mild dish soap
• Time: 45-60 minutes plus an empty wash cycle
• Difficulty: Beginner
• Safety warning: Unplug the washing machine from the wall outlet before cleaning any accessible components. Leave the machine plugged in only for running the clean cycle itself.

Step 1 — Start the Clean Washer cycle#

Drop a single Affresh tablet (part W10501250, the same across every Whirlpool Corporation brand) into the drum itself, not the dispenser, pick the dedicated Clean Washer cycle, and start it. Its hotter water and long agitation are tuned to lift residue off the satin-finish drum without scratching it. No Clean Washer setting? Use the hottest Normal cycle with an Extra Rinse and two cups of white vinegar in the drum.

Step 2 — Clean the dispenser drawer#

While that runs, pull the detergent drawer — press the release tab at the back center on front-loaders, or lift the cup out on top-loaders. Soak it 15 minutes in hot water with a little dish soap, then scrub the softener siphon cap and channels with the soft brush and push a pipe cleaner through the narrow rinse-agent channel, which clogs often. Rinse and air-dry before it goes back.

Step 3 — Clean the door boot seal (front-load)#

Peel back the folds of the rubber boot and wipe every surface with a half-and-half water-and-vinegar solution, concentrating on the bottom of the seal where water pools and mold takes hold. For set-in mildew, dab on a baking-soda paste, leave it 30 minutes, scrub with the soft brush, and wipe clean. Never use bleach on the boot — it breaks the rubber down and cracks it early.

Step 4 — Clean the ProWash sensor#

KitchenAid's ProWash reads soil through a turbidity sensor at the outer-tub drain. On front-loaders, drop the lower front panel (two Torx T20 screws on most, spring clips on newer ones) and wipe the sensor lens with a damp microfiber cloth. On top-loaders the sensor sits by the drain-pump intake, reached by pulling the two Phillips screws at the rear bottom corners and sliding the panel forward. A grimy lens is exactly what makes ProWash cut cycles short.

Step 5 — Wipe the satin-finish drum#

KitchenAid's satin-finish drum is smoother than a standard stainless tub and can hold a thin biofilm ordinary cleaning skips. After the Clean Washer cycle, mist the whole interior with undiluted white vinegar and wipe in circles with a clean microfiber cloth, then run a vinegar-dipped cotton swab through the perforations, which the machine relies on for fill sensing.

Step 6 — Clean the drain-pump filter#

Behind the small door on the lower front panel, lay down towels and a pan, pull the drain plug to bleed residual water, and unscrew the filter counterclockwise. Clear out coins, hair ties, and fibers, rinse it, and scrub the housing with the brush before threading it back clockwise. Replace the filter O-ring if it is cracked.

Step 7 — Clean the exterior and controls#

If your model wears the PrintShield finish, skip standard stainless cleaners — they streak and can harm the coating — and use only warm water with mild dish soap on a microfiber cloth, wiping with the grain. For the control panel, use a barely damp cloth and never spray cleaner at it, since moisture can seep behind the overlay and reach the board.

Step 8 — Final rinse and air-dry#

Run one more rinse-and-spin empty to flush the last of the cleaner, then leave the door or lid open at least four hours to dry the interior. On front-loaders, wipe the door glass and leave the dispenser drawer cracked.

KitchenAid cleaning schedule#

If the odor won't quit#

Check that the drain standpipe sits at least 30 inches high so sewer gas cannot back-siphon, confirm you are using HE detergent (regular suds leave residue ProWash cannot rinse), and run two Clean Washer cycles back-to-back for heavy buildup. The Clean Washer cycle also needs inlet water at 120F to work, so make sure hot water actually reaches the machine.

When to call a professional#

Book a technician if black mold shows behind the drum in the outer tub, if the pump grinds after a filter cleaning (debris at the impeller), if an F5 E2 code appears during the clean cycle (a door-lock fault, not dirt), or if water stays in the drum after the cycle with a clean filter — the pump (KitchenAid/Whirlpool shared WPW10348269) may be failing.
