How to Deep-Clean a Maytag Dishwasher
A full Maytag deep-clean, filters, spray arms, gasket, and a vinegar cycle, takes about 30 to 40 minutes plus one empty cycle and needs no electrical work. It restores spray pressure and clears odors the self-cleaning action cannot reach.
What makes a Maytag different#
Maytag shares the Whirlpool control platform, so the layout is familiar, but its Dual Power Filtration system adds a fine-mesh stage and a stainless chopper that need specific attention. On hard water, the PowerBlast cycle's higher pressure and heat also drive scale onto the spray-arm nozzles faster, so those are the first places buildup hides.
Before you start#
| Category | What you need |
|---|---|
| Tools | Torx T20 driver, soft-bristle brush (an old toothbrush), microfiber cloths, a wooden toothpick or bamboo skewer |
| Supplies | White distilled vinegar, baking soda, dish soap, a spray bottle |
| Time and level | 30 to 40 minutes plus one empty cycle, Beginner |
Safety warning: No electrical disconnection is needed for cleaning. Keep the door open while scrubbing to prevent accidental cycle starts.

Step-by-step#
1 - Pull the racks and spray arms. Slide out both racks. The lower spray arm lifts off its center post with a slight twist, the upper arm unclips by pressing its tab and pulling down, and a third ceiling arm on PowerBlast models releases with a quarter turn counter-clockwise.
2 - Remove the Dual Power Filtration stack. At the bottom center of the tub, twist the cylindrical upper filter counter-clockwise a quarter turn and lift it out, then remove the flat fine-mesh lower filter beneath it. Dual Power Filtration models add a secondary mesh ring around the chopper housing; lift that out too. Leave the stainless chopper blade in place, but inspect it for trapped glass or pit fragments.
3 - Clean the filters. Rinse each part under warm water and scrub the mesh with the soft brush and a drop of dish soap, focusing on the fine-mesh filter where grease film blocks flow. For stubborn buildup, soak the filters in warm water with a couple of tablespoons of vinegar for 15 minutes, then scrub again. Never use a wire brush, which tears the mesh.
4 - Clear the spray nozzles. Hold each arm to the light and push a wooden toothpick into every clogged hole, driving debris inward so it flushes out next cycle. For heavy calcium, soak the arms in undiluted vinegar for 20 to 30 minutes, and give the higher-pressure PowerBlast arm extra attention.
5 - Clean the gasket and tub. Ease the door gasket away from the tub edge and wipe its folds with a vinegar-dampened cloth, especially the bottom corners where water sits. Wipe the inner door around the dispenser and vent, and on stainless tubs wipe the walls and floor to lift water spots.
6 - Clean the sump and chopper housing. With the filters out, clear any glass, labels, or hard debris from around the chopper and wipe the sump walls. A little standing water in the sump is normal and keeps the pump seal wet; cloudy or foul water suggests a drain restriction.
7 - Reassemble and run a vinegar cycle. Refit the filters in reverse, flat mesh first, then the ring, then the cylindrical filter twisted clockwise until it locks, and snap the arms back on. Put a cup of vinegar in a dishwasher-safe bowl on the top rack and run a hot Normal cycle with Heated Dry, not PowerBlast, which would just redistribute loosened debris. Finish by sprinkling a cup of baking soda on the tub floor and running a short rinse.
8 - Wipe down the outside. Clean the door and, on fingerprint-resistant finishes, wipe with the grain. Never spray cleaner directly onto the control panel, since liquid can seep behind the buttons.
Keeping it clean between deep-cleans#
The stainless chopper grinds soft food rather than trapping it, but its housing still collects grease, so run a monthly hot vinegar cycle. Scrape plates but skip pre-rinsing, because the soil sensors set water use from the debris they detect. Hand-clean the Dual Power Filtration stack every 2 to 4 weeks.
Safety First — Know the Risks
Live 120V wiring in a wet environment is one of the most dangerous DIY scenarios. Water + electricity = serious shock risk. Our techs are licensed and insured — let them handle the risk.

Troubleshooting after cleaning#
- Odor lingers: the drain hose lacks a high loop, letting dirty water siphon back. Add a high loop or air gap.
- Still poor washing: confirm the disposal knockout plug was removed at install, a common hidden blockage.
- Trapped moisture smell: on ProDry models the vent fan housing collects lint; clear it.
