Finding the right Maytag dishwasher parts is half the battle when your machine won’t drain, the rack wheels crumble, or the door won’t latch. Most repairs cost $15 to $120 in parts and take under an hour, far cheaper than the $150-plus a technician charges to swap the same component. This guide covers the Maytag dishwasher parts that fail most often, what they cost, and how to match them to your exact model.

Two rules before you order or install anything: cut power at the breaker and shut the water supply valve under the sink. A dishwasher holds a small reservoir of water in the sump, so keep a towel handy even after the water is off.
Find Your Model and Serial Number First
Never buy a part off a photo alone. Maytag stamps the model number on a sticker along the inner edge of the door or on the tub’s left wall when the door is open. It’ll look like MDB4949SKZ or WDT730PAHZ (many current Maytags share the Whirlpool WDT platform). Match parts to that number, because pumps, racks, and control boards changed across model years and a close-looking part often won’t seat right.
The Not-Draining Problem and Its Parts
Standing water in the tub after a cycle is the most common failure, and it usually traces to one of a few cheap parts. Diagnose in order before spending money.
Filter Assembly
Many Maytag models use a manual-clean filter in the tub floor. Twist it out, rinse the mesh under hot water, and clear the coarse filter beneath. A crushed or missing filter lets debris reach the pump; a replacement filter runs $15 to $35. Clean it monthly and you’ll prevent most drainage complaints.
Drain Pump
If the filter is clean but water still sits, the drain pump is the usual suspect. It’s a small motor at the bottom of the tub that pushes wastewater out through the hose. A jammed impeller (glass, a fruit sticker, a toothpick) mimics a dead pump, so pull the cover and check first. A replacement drain pump for most Maytags costs $40 to $110, and it swaps out with a quarter-turn and one wiring connector on many models.
Drain Hose and the Disposal Knockout Plug
The drain hose can kink behind the machine or clog with grease. And if you recently installed a garbage disposal, check the knockout plug, new disposals ship with a solid plug in the dishwasher inlet that must be tapped out. Leave it in and the drain hose is connected to a sealed dead end, which looks exactly like a pump failure. A new drain hose is $20 to $45.
Air Gap
If your setup has a chrome air gap on the sink deck, food debris can pack it solid and back water into the tub. Pop the cap, unscrew the cover, and clear the chamber. The air gap fitting itself is a $10 to $20 part if it’s cracked.
Rack Parts: The Most Ordered Item
Maytag rack wheels and tines are the number-one replacement part, because the vinyl coating eventually chips and the exposed steel rusts. Rack roller/wheel kits run $12 to $30. Broken tines can be patched with tine repair caps at $8 to $15 a set, or you can replace the whole upper or lower rack for $60 to $180. Adjuster clips that let the upper rack raise and lower are a common $15 to $40 fix when the rack sags.
Spray Arms and Wash System
When dishes come out gritty, the spray arm jets are clogged with scale or food. Unclip the lower arm and unscrew the upper, then clear each hole with a toothpick. A cracked or warped spray arm is $25 to $70. The wash pump and motor assembly, which drives the spray, is a bigger job at $90 to $250 and is worth a technician’s hands if you’re not comfortable pulling the machine.
Door Parts
A dishwasher that won’t start often has a bad door latch, the cycle won’t begin until the latch switch confirms the door is closed. A latch assembly runs $20 to $60. Worn door springs or cables, which control how the door drops open, cost $15 to $40 and are noticeable when the door slams down instead of easing. The door gasket (seal) that stops leaks around the tub is a $20 to $50 part.
Electronic Parts
The main control board and the user interface (touchpad) are the pricier components, $100 to $250. Before assuming the board is dead, test the outlet, check the breaker, and confirm the door latch works, since those cheap failures produce the same “won’t turn on” symptom. Only replace a control board once you’ve ruled out the mechanical basics.

Heating Element and Drying Parts
If dishes come out clean but soaking wet, or the machine won’t get hot enough to sanitize, look at the heating element and the high-limit thermostat. Not every Maytag has an exposed element, many newer WDT-platform models use a condensation-dry system with no visible coil, but tub-style models do. A heating element runs $30 to $70 and is held by two nuts under the tub. Before replacing it, test continuity with a multimeter across the terminals; a good element reads a low resistance, an open one reads infinite. The high-limit thermostat that protects it is a $15 to $30 part and a common cause of a machine that heats erratically.
Detergent Dispenser and Rinse-Aid Parts
A dispenser door that won’t pop open mid-cycle leaves detergent caked in the cup and dishes dirty. The dispenser assembly, which includes the wax motor or solenoid that releases the door, runs $30 to $80 on most Maytags. The rinse-aid cap and seal that stops leaks from the reservoir is a cheap $8 to $20 fix when you see rinse aid pooling in the door. These are bolt-in swaps behind the inner door panel, which unscrews with about eight Torx screws.
Float Switch and Overfill Parts
If your Maytag overfills and leaks, or won’t fill at all, the float and float switch in the tub floor may be stuck. The float is a small plastic dome that rises with the water and signals the fill valve to shut. Debris jams it open or closed. Clean around it first, it’s free. If it still misbehaves, the float switch beneath it is a $15 to $35 part. The water inlet valve that the float controls runs $30 to $70 and is the part to replace when the machine won’t fill despite good water pressure.
Where to Buy and How to Save
Order genuine Maytag parts through appliance-parts retailers or the manufacturer using your model number. OEM parts fit better and last longer than generic substitutes, but for wear items like rack wheels and tine caps, quality aftermarket kits are fine and cost a third as much. Always compare the old part side by side with the new one before installing, and keep the packaging until you’ve confirmed the machine runs a full cycle.
Tools You’ll Need
Most Maytag parts jobs use the same short list: a Torx T15 and T20 driver for the inner door and toe panel screws, a Phillips screwdriver, a quarter-inch nut driver for the heating element and tub nuts, needle-nose pliers, and a multimeter for testing switches and elements. Keep a shallow pan and towels for the sump water. If you’re pulling the whole machine to reach the pump or hose, you’ll also need a screwdriver to release the mounting brackets under the countertop and an adjustable wrench for the water-supply compression fitting. None of it is specialized, and it all fits in a single toolbox.
Bottom Line
Most Maytag dishwasher parts failures are cheap, mechanical, and DIY-friendly, filters, hoses, rack wheels, and latches cover the vast majority of calls. Cut power and water first, match every part to your exact model number, and work from the cheapest likely cause upward. Do that and you’ll keep a $600 dishwasher running for a decade on twenty-dollar parts instead of replacing it.
