Maytag Dishwasher Is Noisy: Common Causes and DIY Fixes

A dishwasher should hum quietly in the background, not rattle the kitchen. So when your Maytag dishwasher is noisy, something specific is almost always behind it: a loose spray arm, a clogged filter, a worn pump, or dishes that weren’t loaded right. Some fixes take five minutes. Others point to a part on its way out. Below, we’ll walk through the common causes, then show you how to fix each one before you spend money on professional dishwasher repair.

Common Reasons Your Maytag Dishwasher Is Noisy

First, a quick note on diagnosis. The type of sound matters, and so does the timing, so pay attention to when the racket starts before you open anything up.

Loose Spray Arm

Spray arms loosen over time. Once they do, they clip the racks or scrape tall dishes mid-cycle, and you’ll hear a rhythmic ticking that stops the moment the wash pauses.

Clogged Filter

Food debris builds up in the filter at the bottom of the tub. Because the wash pump then has to force water through that blockage, it strains, and the strain comes out as a low growl or rattle.

Worn Wash Pump or Motor

This is the sound most owners dread. A worn wash pump or failing motor bearing produces a steady droning or squealing that gets louder as your Maytag dishwasher ages, and unlike a stray fork in the tub, it won’t fix itself.

Faulty Drain Pump

Listen for buzzing or grinding at the end of the cycle, right when the machine drains. However, before you blame the pump itself, check for glass fragments or fruit seeds caught in the impeller, because debris causes the same racket. If the impeller is damaged, a dishwasher repair technician can usually swap the pump in one visit.

Improper Dish Loading

Honestly, this is the cause we find most often. Plates touching. Cutlery poking through the rack. A plastic lid bouncing around the top shelf. So before you take anything apart, run a short empty cycle and listen.

How to Fix a Noisy Maytag Dishwasher

Most of these dishwasher repair jobs need nothing more than a screwdriver, a soft brush, and twenty minutes. Start with the easiest fix.

Inspect and Clean the Filter

First, remove the bottom rack. Next, twist the cylindrical filter counterclockwise and lift it out along with the flat mesh screen underneath it. Then rinse both parts under warm water and scrub away stuck-on grease with a soft brush. Finally, lock everything back into place and run a rinse cycle. Quieter already? The filter was your problem.

Check the Spray Arms

Spin each arm by hand. It should rotate freely without wobbling or catching the racks above it. If the lower arm feels loose, tighten the retaining nut or press the arm back onto its mount until it clicks. Also, clear the spray holes with a toothpick, because blocked jets throw off water pressure and add a hiss of their own. Two minutes. That’s all this check takes.

Inspect the Pump and Motor

Cut power at the breaker first. Always. Then remove the lower spray arm and the filter so you can see into the pump housing, and check for broken glass, bones, or hard plastic caught around the impeller. Clear anything you find with pliers, not your fingers. If the impeller is clean yet your Maytag dishwasher still drones or squeals mid-wash, the motor bearings are likely worn. As a result, this is where most owners call for Maytag dishwasher repair instead of replacing the pump assembly themselves. Fair enough. Motor work involves seals and torque specs that are easy to get wrong.

Reload Dishes Properly

Leave space between plates. Point knife blades down. Additionally, secure lightweight plastic containers on the top rack, since the spray can flip them mid-cycle. If your Maytag dishwasher is noisy only when it’s fully packed, loading is the culprit, and this fix costs nothing.
