Maytag DWU7802AAM dishwasher Parts

For a Maytag dishwasher like model DWU7802AAM, the most common problems we see are not draining, not cleaning well, and leaking. In many cases, the root cause is a clogged filter, blocked spray arm, or a fill or seal issue such as a worn dishwasher door seal WP902894.

Most common symptoms and what usually causes them

• Not draining: food debris in the sump area, a restricted drain hose, or a blocked filter
• Poor cleaning: clogged spray arm holes, overloaded racks, or low water fill
• Leaking at the door: worn or mis-seated door seal, or dishes preventing the door from closing fully
• Not filling enough: water supply valve not fully open, float stuck, or a failing inlet valve
• Detergent not dispensing: dispenser mechanism issue or dishes blocking the dispenser door

Quick checks you can do first (no parts needed)

• Remove and rinse the filter and the area beneath it; clear any glass or labels.
• Spin the spray arms by hand; clear clogged holes with a toothpick.
• Confirm the sink drain and garbage disposal are clear (new disposals often have a knockout plug).
• Verify the water shutoff valve is fully open and the inlet line is not kinked.
• Check that the float moves freely up and down and is not jammed by debris.

Parts that commonly fix these issues on DWU7802AAM

Symptom	Common part to inspect	What it affects
Leaks at the door	Dishwasher door seal WP902894	Keeps water from escaping around the door
Not filling or fills slowly	Dishwasher water inlet valve WP99001359	Controls water entering the dishwasher
Poor wash performance	Filter WP99001791	Prevents debris from recirculating onto dishes
Overfilling or fill errors	Float WP99002363	Signals water level to stop filling

Why it matters

A dishwasher that is not draining, not cleaning, or leaking often gets worse over time; debris buildup can reduce wash pressure, and small door leaks can damage flooring. Catching the cause early usually prevents bigger repairs.

Yes. For the Maytag DWU7802AAM dishwasher, we see many DIYers successfully replace common wear parts (like a door seal, rack stops, or a float) with basic hand tools after shutting off power and water; electrical and plumbing repairs take more care.

Good DIY replacements for this model

These repairs are typically straightforward and low-risk when you work carefully:

• Replace a leaking door gasket with the dishwasher door seal WP902894
• Fix a door that drops or won’t stay open with the dishwasher door spring WP912652
• Address overfilling symptoms by checking the float WP99002363
• Improve wash performance by cleaning or replacing the filter WP99001791
• Stop a rack from sliding off the track by replacing the rack stop WP99002135

Repairs that are more advanced

These can still be DIY, but they involve wiring, water connections, or tight access behind the toe panel:

Repair type	What you’ll handle	Typical skill level
Water fill problems	Water line connection, clamps, valve wiring	Intermediate
No-wash or weak wash	Pump area access, seals, impeller fit	Intermediate to advanced
Door balance issues	Spring tension, routing, mounting points	Intermediate

If the dishwasher won’t fill, a common part involved is the dishwasher water inlet valve WP99001359.

Safety and prep checklist

Before you start any Maytag dishwasher repair:

• Turn off power at the breaker (do not rely on the door switch)
• Shut off the water supply valve under the sink
• Place towels under the front edge; expect some water
• Take photos of wire and hose routing before disconnecting anything
• Use the correct fasteners and clamps; replace damaged clamps like the clamp spring WP596669

Why it matters

DIY replacement can restore cleaning, stop leaks, and prevent cabinet or floor damage. It also helps you avoid replacing the entire dishwasher when only a single part (seal, spring, float, or valve) is worn.

In a Maytag dishwasher like model DWU7802AAM, the most commonly replaced parts are the ones that handle sealing, filling, washing circulation, and rack movement. These parts wear from heat, detergent, vibration, and mineral buildup, and they are also the most likely to cause leaks, poor cleaning, or no-fill symptoms.

Commonly replaced dishwasher parts (and what they affect)

• Door sealing parts: stop leaks around the tub opening (example: dishwasher door seal WP902894)
• Door balance parts: keep the door from slamming or dropping (example: dishwasher door spring WP912652)
• Water fill parts: control incoming water and fill level (example: dishwasher water inlet valve WP99001359, water switch WP99002560, float WP99002363)
• Wash circulation parts: move water through spray arms for cleaning (example: circulating WP902461)
• Filtration and soil handling: reduce redeposit and protect the pump (example: filter WP99001791)
• Racks and rack hardware: fix rust, broken tines, or poor sliding (example: rack W10139223, rack stop WP99002135)

Quick symptom-to-part guide

Symptom	Most likely part area	Example part for DWU7802AAM
Water on floor at the door	Door seal or door alignment	WP902894
Door drops open or won’t stay up	Door spring/hinge balance	WP912652
Dishwasher won’t fill	Inlet valve, float, water level sensing	WP99001359, WP99002363, WP99002560
Poor cleaning or weak spray	Circulation/impeller, filter, clogs	WP902461, WP99001791
Lower rack won’t slide right	Rack stops/track wear	WP99002135

Why it matters

Replacing the right “high-wear” part first prevents repeat failures and protects bigger components like the circulation system. For example, a leaking door seal can damage flooring, and a sticking float can stop filling and leave dishes dirty.

A Maytag dishwasher like model DWU7802AAM is built around a water-fill system, a wash (circulation) system, and door/rack components that keep water inside while spraying and filtering it. Most repairs trace back to filling, draining, leaking, or poor cleaning, which map directly to these core parts.

Main dishwasher parts (what they do)

• Water inlet valve: lets household water enter the tub at the start of a cycle (example: dishwasher water inlet valve WP99001359).
• Overfill protection float and switch: prevents overfilling by signaling the dishwasher to stop filling (examples: float WP99002363 and water switch WP99002560).
• Circulation system: moves wash water through the spray arms; includes the pump/impeller (example: circulating WP902461).
• Filtration system: traps food soil so it does not redeposit on dishes (example: filter WP99001791).
• Door sealing and balance parts: keep leaks out and control door movement (examples: dishwasher door seal WP902894 and dishwasher door spring WP912652).
• Racks and rack hardware: hold dishes and allow smooth sliding (examples: rack W10139223 and rack stop WP99002135).

Quick “symptom to part” guide

Symptom	Parts to check first	Common result
Not filling	Water inlet valve, float, water switch	No wash action because tub stays low
Leaking at door	Door seal, door alignment, rack interference	Water drips from corners or bottom
Not cleaning well	Filter, circulation/impeller, loading	Food left on dishes, weak spray
Door drops open	Door spring	Door feels heavy or slams

Why it matters

Knowing the major parts helps you troubleshoot faster and buy the right replacement the first time. For example, a “not filling” complaint usually points to the inlet valve or float system, while “not cleaning” often points to filtration or circulation.
