Maytag DWU7702AAB dishwasher Parts

On a Maytag dishwasher like model DWU7702AAB, the model number is printed on the rating label located just inside the door opening, typically along the left side of the tub frame. The same label usually lists the serial number.

• Open the dishwasher door fully.
• Look along the left inner edge of the tub opening.
• Check the vertical frame area where the door closes.
• Wipe the area with a damp cloth if the label is hard to read.
• Write down the full model number and serial number exactly as shown.

We use the exact model number to match the correct Maytag dishwasher parts and diagrams for your unit. Even small model-number differences can change fit for items like a dishwasher door seal WP902894 or a door switch 99002254.

The most common Maytag dishwasher problems are poor cleaning and draining issues. On the Maytag DWU7702AAB, these are usually caused by a clogged filter, blocked spray arm holes, or loading that prevents water from reaching dishes; less often, a failed fill component causes weak wash performance.

• Dishes still dirty or gritty: filter clogged, spray arm holes blocked, or overloading
• Water left in the tub: drain path restriction (food debris) or a drain component issue
• Leaks at the door: worn door seal or door not closing squarely
• Won’t start or stops mid-cycle: door not latching, door switch not closing
• Poor fill or weak spray: water supply valve not fully open or inlet valve problem

1. Remove and rinse the filter area; clear seeds, glass, labels, and grease.
2. Spin the lower spray arm by hand; clear clogged jets with a toothpick.
3. Confirm the sink drain and disposer inlet are clear (new disposer plugs are a common miss).
4. Load so tall items do not block the spray arm or detergent cup.
5. Run hot water at the sink before starting to improve wash temperature.

If cleaning and loading checks do not help, these model-matched parts are frequent solutions:

Most “bad dishwasher” complaints are flow problems: if water cannot enter strongly, circulate freely, and drain cleanly, the cycle finishes but results are poor. Keeping the filter and spray arm clear prevents repeat clogs and protects the circulation system.

A Maytag dishwasher such as model DWU7702AAB is built around a fill system, wash (circulation) system, filtration, and door safety/sealing parts. Common serviceable parts include the water inlet valve, spray arm, filter, float, racks, and door switch and seal.

• Water fill: brings water into the tub and controls fill level
• Wash circulation: moves water through spray arms to clean dishes
• Filtration: traps food soil to protect the pump and improve cleaning
• Drain: pushes used water out to the sink drain/disposer
• Door and safety: keeps the door sealed and confirms it is closed before running

Here are examples of parts we commonly see customers replace on this Maytag dishwasher:

Knowing which system a symptom belongs to speeds up troubleshooting and helps you order the right replacement part the first time. For example, “won’t fill” points to the inlet valve or float, while “not cleaning” often points to the spray arm or filter.

• For cleaning problems, use dishwasher not cleaning dishes video to narrow down spray, filter, and loading issues.
• If your dishwasher shows a fault pattern, check Maytag microclean he dishwasher error codes for code meanings and next steps.

Yes. Some dishwashers have an automatic door-release feature that pops the door open near the end of the dry cycle to vent hot, moist air and improve drying. Your Maytag DWU7702AAB may or may not include this feature; it depends on the exact design and control system.

On models that support it, the control opens the door slightly after the heated dry portion ends. That small gap helps moisture escape so dishes dry faster with less condensation.

Common characteristics:

• Door opens a small amount (often 1 to 4 inches)
• Happens after the dry cycle, not during washing
• Improves drying, especially for plastics
• May be enabled or disabled depending on the cycle/options

Use this quick checklist during a normal cycle:

• Start a cycle and listen near the end for a click from the latch area
• Check whether the door is unlatched or slightly ajar after the cycle completes
• Confirm the door still seals normally when closed (no rubbing or binding)
• If the door is popping open early, inspect the latch and switch system

If the door will not stay closed or the dishwasher will not start, the latch or door switch circuit is a common place to check.

A door-open dry system can reduce water spots and improve drying performance without increasing heater time. If the door is opening at the wrong time, it can also cause leaks or stop the cycle, so it is important to separate “normal venting” from a latch or seal problem.

Warranty length for a Maytag dishwasher depends on the exact model and the warranty statement that came with it. For Maytag DWU7702AAB, use the warranty document tied to your purchase date and serial number; coverage can differ by component and by year.

Use these details to match the correct Maytag warranty coverage for your DWU7702AAB:

• Purchase date (warranty starts from purchase, not installation)
• Serial number (Maytag uses it to identify production series)
• Whether you are the original owner (some coverage is owner-specific)
• Which part failed (many warranties are “limited” to certain components)
• Whether labor, trip charges, and diagnostics are included

Many dishwasher warranties separate “parts” coverage from “labor” coverage. Here is the common structure you will see on warranty statements:

Warranty decisions come down to the failed component and the warranty’s definitions. Identifying the likely failed part first helps you decide whether to schedule warranty service or proceed with a DIY repair.

These model-matched parts are commonly involved in “won’t start,” “leaks,” or “won’t fill” complaints:

• Door not latching or no start: door switch 99002254
• Leaking at the door: dishwasher door seal WP902894
• Not filling with water: dishwasher water inlet valve WP99001359

On a Maytag DWU7702AAB dishwasher, the F8 E2 error points to a drain system problem, most often the drain pump circuit or a drain pump that is not operating correctly. We focus first on simple drain restrictions, then move to electrical checks and part replacement if needed.

• Cancel the cycle and let the unit attempt to drain; listen for the drain pump running.
• Check the sink drain and garbage disposal (a clogged sink drain can mimic a dishwasher drain failure).
• Inspect the drain hose for kinks, crushing, or a high loop that fell down.
• Look for standing water and clear debris around the sump area.
• Turn power off at the breaker for 1 minute, then restore power and retry a drain.

If the dishwasher drains slowly, not at all, or the code returns quickly, these model-matched parts are common suspects:

• Dishwasher water inlet valve WP99001359 (if the unit overfills and then struggles to drain)
• Float WP99002363 (if the dishwasher thinks it is overfilled and behaves erratically)
• Filter WP99001791 (if debris is restricting water flow and contributing to poor draining)

A true drain pump electrical fault can stop the cycle and leave dirty water in the tub. Catching it early helps prevent odors, poor cleaning, and repeat shutdowns.
