KitchenAid KDTM704KPS1 dishwasher Parts

For the KitchenAid KDTM704KPS1 dishwasher, the most common day-to-day problem we see is poor cleaning or standing water caused by restricted water flow: a dirty filter, blocked spray paths, or a drain restriction. Leaks from door sealing surfaces are also common as the unit ages.

Most common symptoms and what they usually point to

• Dishes still dirty or gritty: clogged filter, blocked spray arm holes, or low water fill
• Water left in the bottom: drain hose restriction, clogged filter area, or drain path blockage
• Bad odor: food debris trapped in the filter/sump area
• Leaks at the front: door sealing issue or tub gasket wear
• Won’t start or stops mid-cycle: door latch not closing/switch not proving closed

Quick checks we recommend first (no parts needed)

• Clean and reseat the filter; check for glass, labels, and seeds in the sump area.
• Spin spray arms by hand to confirm they move freely; clear any blocked holes.
• Verify the sink drain and garbage disposal inlet are clear (a common drain backup cause).
• Confirm the door closes firmly and the latch engages.
• Run a maintenance cleaning cycle to reduce grease and odor buildup.

Parts that commonly solve these problems on KDTM704KPS1

Symptom	Common fix	Part to consider
Poor cleaning, debris recirculating	Clean or replace the filter	Dishwasher filter W11568785
Not filling or fills slowly	Check inlet supply; replace valve if weak	Fill valve assembly W11434044
Leaking at the bottom/front edge	Replace the lower door seal	Seal, door bottom W11664713
Won’t start, door won’t “click” shut	Replace latch/switch assembly	Latch assembly (includes switch) W11412299

Why it matters

Restricted water flow and drainage make every cycle less effective: detergent does not dissolve correctly, spray pressure drops, and food soil can redeposit on dishes. Catching a clogged filter or a weak fill valve early also helps prevent pump strain and repeat clogs.

A KitchenAid dishwasher typically lasts 10 to 14 years with normal household use and basic upkeep. For your KitchenAid KDTM704KPS1, consistent cleaning, good water quality, and fixing small issues early are what most often determine whether it lands closer to 10 years or pushes past 14.

What affects lifespan the most

• Filter and sump cleanliness (food soil left behind makes the pump work harder)
• Water quality (hard water speeds up mineral buildup)
• Loading habits (overloading blocks spray and strains racks and rails)
• Detergent and rinse aid use (too much or the wrong type can cause residue)
• Early leak or fill problems (small drips and slow fills shorten component life)

Maintenance that helps you reach the high end of the range

• Clean the filter regularly; replace it if it is damaged or won’t come clean (see dishwasher filter W11568785).
• Run a monthly cleaning cycle using a dishwasher cleaner.
• Check the lower spray arm for clogs and cracks; replace if it stops spinning freely (see dishwasher spray arm, lower W11550888).
• Keep the door sealing surfaces clean; address leaks promptly.
• If you notice slow filling or no-fill symptoms, inspect the inlet components early (see fill valve assembly W11434044).

Quick “wear item” guide for KDTM704KPS1

Item	What you’ll notice	Typical action
Filter	Grit, odor, poor cleaning	Clean; replace if damaged
Spray arm	Poor wash coverage, debris in holes	Clean holes; replace if warped/cracked
Fill valve / inlet	Long fill times, not filling	Check supply; replace failed valve
Door seals	Drips at the front/bottom	Clean mating surfaces; replace worn seal

Why it matters

Most dishwasher “end of life” failures start as performance issues (not cleaning, not draining, leaking). Staying ahead of filter, spray, and water-inlet problems reduces strain on the pump and motor and helps your KitchenAid KDTM704KPS1 reach its full service life.

Common KDTM704KPS1 parts customers replace

If you are troubleshooting a specific issue, these are frequently ordered items for this model:

Symptom	Part to check first	Example part for this model
Not filling with water	Fill valve / water inlet	Fill valve assembly W11434044 or water inlet W11535094
Not draining	Drain hose / drain path restriction	Dishwasher drain hose W11551233
Poor cleaning	Filter / spray arm	Dishwasher filter W11568785 or dishwasher spray arm, lower W11550888
Door won’t latch or won’t start	Door latch switch assembly	Latch assembly (includes switch) W11412299

Quick checks before you buy

These steps often pinpoint the correct replacement part:

• Not filling: verify the shutoff valve is open and the inlet screen is not clogged.
• Not draining: check for a kinked hose and a blocked sink/disposer connection.
• Not cleaning: clean the filter and inspect spray arm holes for debris.
• Won’t start: confirm the door closes firmly and the latch engages.

Why it matters

Dishwashers use model-specific electrical connectors, seals, and mounting points. Ordering by KDTM704KPS1 and confirming the part ID helps ensure proper fit, prevents leaks, and restores normal wash performance.

For the KitchenAid KDTM704KPS1 dishwasher, the most commonly replaced parts are the ones tied to water flow, draining, washing action, and door sealing: inlet and fill components, filters, drain hoses, spray arms, and the door latch and seals. These parts wear from heat, detergent, hard-water buildup, and normal use.

Commonly replaced parts (and what they affect)

• Filling issues: fill valve assembly W11434044, water inlet W11535094
• Not draining or slow draining: dishwasher drain hose W11551233, hose-drain,e W11414944
• Poor cleaning: dishwasher filter W11568785, dishwasher spray arm, lower W11550888, dishwasher manifold and spray arm assembly W11545334
• Leaks at the door: gasket-tub,d W11483553, seal, door bottom W11664713
• Won’t start or stops mid-cycle: latch assembly (includes switch) W11412299

Quick symptom-to-part guide

Symptom	Most likely area	Example parts for KDTM704KPS1
Won’t fill or fills slowly	Water inlet system	W11434044, W11535094
Water left in tub	Drain path	W11551233, W11414944
Grit, film, or food left on dishes	Filtration or spray	W11568785, W11550888, W11545334
Water leaking from the front	Door sealing	W11483553, W11664713
Door won’t latch, won’t run	Door latch switch	W11412299

Why these parts fail most often

• Filters clog from food soil and grease
• Spray arms plug from mineral scale and debris
• Hoses kink, split, or clog at the sink connection
• Door gaskets flatten or tear and start weeping
• Inlet valves stick or restrict from sediment

Why it matters

Replacing the right wear part restores wash pressure, proper fill level, and leak-free sealing; that prevents repeat clogs, standing water odors, and pump strain. For troubleshooting steps by symptom, use dishwasher not cleaning dishes video or dishwasher not draining video.
