Maytag Dishwasher Not Cleaning Dishes: Causes and Fixes
Quick Answer
Maytag dishwasher not cleaning dishes: check the most common cause first (see step 1 below). Maytag uses brand-specific components that differ from other manufacturers.
Honestly, about 60% of the Maytag dishwashers I get called out for not cleaning have a clogged filter. That's it. Maytag's Dual Power Filtration uses a finer mesh than most brands, and it fills up faster than you'd think. Ignore it long enough and your motor's working twice as hard, which shortens its life. The fix is usually free, but leave it too long and you're looking at a pump replacement.
Maytag Dishwasher Not Cleaning Dishes: Causes and Fixes
OK so here's the deal. Most of the time a Maytag not cleaning is something simple, a dirty filter, a clogged spray arm, maybe not enough water getting in. These are solid machines, Whirlpool builds them, and they're made to last. But that fine-mesh filter Maytag uses fills up fast and most people don't even know it needs cleaning. I'd say 6 out of 10 calls I go on for this end up being a free fix.

Symptoms You May Notice
Dishes come out with white film or visible food bits still stuck in corners and crevices, even after a full 90-minute normal cycle.
Glasses look cloudy or have a greasy film right after washing, almost worse than before.
Bottom rack items are clean but top rack dishes are still dirty, or you've got the opposite problem with bad coverage on the bottom.
You can actually smell food odor on dishes that are supposed to be clean.
Standing water in the bottom of the tub when the cycle ends, which usually means drainage and cleaning are both compromised at the same time.
Can you reset a Maytag dishwasher to clear the NOT-CLEANING code?
For a basic reset, press and hold Cancel for 3 seconds until all the lights go out, then wait 2 full minutes before starting a new cycle. You can also just unplug the dishwasher for 60 seconds. To check stored codes first, press Heated Dry, Normal, Heated Dry, Normal within 5 seconds, write down any codes shown, then press Cancel to clear and exit. After any reset, run a Normal cycle with a fresh pod to see if cleaning improved.

Frequently Asked Questions
How much does it cost to fix a Maytag dishwasher not cleaning dishes?
Depends entirely on the cause. If it's the filter or spray arms, that's free, you just clean them. A detergent dispenser spring is $8-15 and takes 20 minutes to swap. Water inlet valve runs $30-60 for the part. Wash motor or pump assembly is where it gets expensive, $150-250 for the part, plus $100-150 labor if you're paying a tech. If someone's quoting you more than $400 on a dishwasher that's over 8 years old, honestly just put that money toward a new one.
How often should I clean the filter on my Maytag dishwasher?
Every month if you run it daily and don't pre-rinse dishes. Every 2-3 months if you're lighter on use and usually scrape food off before loading. I tell people to add it to the same mental schedule as changing a furnace filter. Pull it out, give it a 30-second scrub under the sink, put it back. Takes less time than unloading the dishwasher. Maytag even puts a reminder in the owner's manual but honestly nobody reads those.
Why are my Maytag dishwasher's top rack dishes still dirty but the bottom rack is clean?
Upper spray arm is almost certainly clogged. That arm feeds water to the top rack exclusively, and if even half the holes are blocked with mineral deposits you'll get terrible coverage up there. Pull that arm off, hold it up to a light, and check every single hole with a toothpick. Also make sure the arm can spin freely, sometimes it gets bumped out of position and is rubbing against the rack. Takes 5 minutes to check. If the arm is clear and spins fine, you might have a pressure issue where the upper arm just isn't getting enough flow from the pump.
Why does my Maytag clean dishes on PowerBlast but not on Normal cycle?
That's a classic wash motor symptom and I saw it just last Tuesday on an MDB7959SKZ. PowerBlast runs the motor at higher RPM and temperature, generating more pressure and better spray coverage. Normal cycle runs it at lower intensity to save energy. When the motor's wearing out it can still generate enough pressure at full blast but not at normal operating speed. It's like a car that drives fine on the highway but sputters around town. The motor's not dead yet but it's on the way out. Part number for the pump assembly on most MDB series is W10482480, but confirm with your model number first.
Can I run Maytag diagnostic mode myself?
Yep, it's easy. Press Heated Dry, Normal, Heated Dry, Normal within about 5 seconds. You should see numbers or letter-number codes show up on the display. These are stored fault codes the machine has logged. Write them down and look them up here or in a forum. The diagnostic will also run the dishwasher's components automatically if you let it go, which can help identify a weak motor or failing valve. Press Cancel when you're done to exit back to normal mode.
Is it worth repairing a Maytag dishwasher that won't clean dishes?
If it's under 8 years old, almost always yes. Maytag makes solid machines and most not-cleaning issues are cheap to fix. The 50% rule is a decent guide: if the repair costs less than half of a comparable replacement (usually $600-800 for a new mid-range dishwasher), just fix it. Over 10 years old and you're looking at a pump or motor replacement, that's a harder call. Also check if you have Maytag's extended warranty or a home warranty policy, they sometimes cover this exact type of repair.
