Maytag MDB7100AWQ dishwasher Parts

Maytag has offered 10-year limited parts warranties on some dishwashers, but coverage varies by model and by component. For your Maytag MDB7100AWQ dishwasher, confirm the exact warranty terms, covered parts, and exclusions in the MDB7100AWQ owner's manual.

What “10-year limited parts warranty” typically means

A limited parts warranty usually covers specific components for parts only (labor is often excluded), and it includes conditions and exclusions.

Common details to verify for MDB7100AWQ:

• Which components are covered for the full 10 years (often select major parts)
• Whether labor, trip charges, and diagnostics are included or excluded
• What proof of purchase is required (receipt or other documentation)
• Whether coverage changes for commercial or non-residential use
• What process is required to request warranty service

What to do if you think a covered part failed

Start with the symptom and the part of the dishwasher involved (fill, drain, leak, or will not start). Then document your model and serial number and gather proof of purchase.

Quick checks we recommend:

• Write down the model and serial number from the dishwasher
• Note the failure symptom and when it happens in the cycle
• Check for obvious issues first (door fully latched, water supply on)
• If the unit will not start, check the door latch circuit (a failed door switch can stop operation)
• If the unit leaks, inspect the door gasket for tears or gaps

Parts that commonly relate to warranty-type symptoms

These are examples of parts on the MDB7100AWQ parts list that match common complaints:

Symptom	Common related part	Example part on this model
Will not start or stops mid-cycle	Door interlock/switch	Door switch 99002254
Leaks at the door	Door gasket/seal	Dishwasher door seal WP902894
Not filling or fills slowly	Water inlet valve	Dishwasher water inlet valve WP99001359

Why it matters

Warranty coverage is specific to the model and the failed component. Checking the MDB7100AWQ warranty language first helps you avoid paying for parts or service that may be covered, and it ensures you follow the correct service process.

Yes. The Maytag MDB7100AWQ dishwasher uses a self-cleaning interior with a strainer area; we recommend periodically checking the bottom of the tub and removing any large particles that did not pass through the strainer to help prevent poor cleaning and drain issues. See the MDB7100AWQ owner's manual for routine care details.

What to clean (and what “self-cleaning” means)

Even on self-cleaning designs, food debris can collect where water flows through the strainer area at the bottom of the tub.

• Pull out the lower rack so you can see the tub bottom clearly
• Look for labels, glass, bones, twist ties, or heavy food pieces
• Remove debris by hand (wear gloves if sharp items are present)
• Wipe the inner door edge/liner to remove splashes and soils
• Avoid abrasive pads or powders on the front or interior surfaces

Quick maintenance checklist

Use this simple schedule to keep wash performance consistent.

Task	What to do	Typical frequency
Check tub bottom/strainer area	Remove large particles	Weekly to monthly
Wipe inner door edge	Remove food splashes	Weekly
Run a cleaning cycle	Use a dishwasher cleaner	Monthly
Confirm spray action	Make sure arms spin freely	Monthly

When cleaning the “filter area” matters most

Cleaning the tub bottom and strainer area is especially important if you notice any of these symptoms:

• Grit or food left on dishes after the cycle
• Cloudy glasses (especially after heavy soil loads)
• Standing water or slow draining
• Odors after the cycle completes
• Lower spray arm not turning freely

If you are also troubleshooting wash performance, our dishwasher not cleaning dishes video can help you narrow down causes such as loading, detergent, and spray coverage.

Why it matters

Large debris that stays in the tub can interfere with water circulation and soil removal. Keeping the strainer area clear helps the dishwasher wash, drain, and rinse more consistently, and it reduces the chance of clogs and redepositing food onto dishes.

A Maytag dishwasher like model MDB7100AWQ is built around a water-fill system, wash (circulation) system, drain system, and door/safety controls. The key parts include the water inlet valve, spray arms, racks, float (overfill protection), door seal, and door switch.

Main dishwasher parts and what they do

• Water inlet valve: opens to let household water into the tub (common fill problems point here). See dishwasher water inlet valve WP99001359.
• Float (overfill protection): rises with water level and helps prevent overfilling. See float WP99002363.
• Spray arms: spin and distribute water for cleaning. See dishwasher spray arm assembly, lower WP99001788.
• Racks and rack hardware: hold dishes and allow water flow (lower rack, stops, tines).
• Door seal and door switch: prevent leaks and confirm the door is closed so the unit can run. See dishwasher door seal WP902894 and door switch 99002254.
• Drain hose: carries wastewater to the sink drain or disposer. See dishwasher drain hose WP99001782.

Quick “system view” of how the parts work together

Dishwasher system	What you notice when it fails	Common parts involved
Fill	Won’t fill, fills slowly	Water inlet valve, float
Wash	Poor cleaning, weak spray	Spray arm, racks blocking spray
Drain	Water left in bottom	Drain hose (and drain path)
Door/safety	Won’t start, stops mid-cycle, leaks	Door switch, door seal

Where to find the exact part locations for MDB7100AWQ

Use the MDB7100AWQ owner's manual to match symptoms to components and to confirm access steps and safety guidance (power off before service).

Why it matters

Knowing which system is acting up (fill, wash, drain, or door/safety) helps you choose the right Maytag dishwasher parts the first time and avoid replacing good components.
