KitchenAid KUDS35FXSS8 undercounter dishwasher Parts

The most common KitchenAid dishwasher issue is poor cleaning (dirty dishes) caused by restricted water flow from a clogged filter or spray arm, or low fill. On the KitchenAid KUDS35FXSS8, the next most common complaints are draining problems and leaks.

Quick checks we recommend first

• Confirm the water supply is turned on and the dishwasher is filling.
• Make sure the door closes tightly and latches.
• Run the shortest cycle and check for water in the bottom of the tub after about 2 minutes.
• Look for standing water at the end of the cycle (drain problem).
• Check for drips at the water inlet connection and drain hose connection.

For model-specific operating steps and cycle behavior, follow the KUDS35FXSS8 owner's manual.

Most common symptoms and the usual causes

Symptom	Most likely cause	What to do next
Dishes still dirty	Spray arm holes blocked, filter/sump area restricted, low water fill	Clean spray arm and filter area; verify strong fill
Water left in tub	Drain path restricted, drain pump not moving water	Check drain hose routing and air gap/disposer inlet; test pump
Leaking	Loose fittings, worn door seal, drain hose connection seep	Tighten fittings, inspect seals/hoses
Won’t start	Door not latched, power issue, cycle not set	Verify latch, breaker/fuse, cycle selection

Parts that commonly fix these problems

If troubleshooting points to a failed component, these are common replacements for this model:

• Drain issue: dishwasher drain pump WPW10348269
• Leak at the bottom edge of the door: dishwasher door seal, lower WPW10497235
• Poor wash performance or unusual wash noise: dishwasher sump and motor assembly WPW10780877
• No heat or poor drying: dishwasher heater W10703867

Why it matters

Poor cleaning and draining problems usually get worse over time; restricted flow can leave detergent undissolved, cause odors, and extend cycle times. Catching a small leak early also helps prevent cabinet and flooring damage.

Installation-related causes to rule out

Improper connections can mimic “common problems,” especially right after a move or install:

• Water supply fitting not sealed or overtightened
• Drain hose not fully seated or clamped
• Dishwasher not centered or leveled, causing door rub and leaks

Use the KUDS35FXSS8 installation guide to verify water and drain connections and to check leveling and centering.

Most KitchenAid dishwashers, including the KitchenAid KUDS35FXSS8, typically last 10 to 14 years with normal household use. Consistent maintenance, correct installation, and good water quality do the most to keep the wash system, heater, and pumps running reliably over time.

What affects dishwasher lifespan the most

• Water quality: hard water speeds up mineral buildup on internal parts
• Detergent and rinse aid use: proper dosing improves cleaning and reduces residue
• Filter and sump cleanliness: debris left in the system strains the motor and drain path
• Loading habits: overloading can block spray arms and reduce wash performance
• Heat and drying performance: poor drying can signal heater or airflow issues

Maintenance that helps you reach the full lifespan

We recommend these habits for the KUDS35FXSS8:

• Use rinse aid regularly (it improves drying and helps control hard-water deposits)
• Run hot water at the sink before starting a cycle so the dishwasher fills with hotter water
• Clean out visible debris in the bottom of the tub after heavy loads
• Keep spray paths clear by loading so dishes do not block the spray arm
• Fix small issues early (slow draining, unusual noise, poor drying)

Common “wear-out” items and what they do

Part area	What you may notice	Example part for this model
Drain system	Water left in tub, slow drain	Dishwasher drain pump WPW10348269
Heating/drying	Wet dishes, cooler water, longer dry time	Dishwasher heater W10703867
Water fill	Not enough water, weak wash, fill errors	Dishwasher water inlet valve WPW10327249

Why it matters

A dishwasher that is maintained and installed correctly usually reaches the higher end of the lifespan range because the motor, heater, and drain path are not forced to work harder than necessary. For model-specific operating and care guidance, follow the KUDS35FXSS8 installation guide and your use and care instructions.

On KitchenAid dishwasher model KUDS35FXSS8, a “rubber seal” issue is usually the door gasket or the lower door seal coming loose, getting twisted, or not seating evenly. The fix is to clean the channel, press the seal in fully and evenly, then keep the door closed for several hours so it holds its shape (use the steps in the KUDS35FXSS8 installation guide).

Quick fix steps (reseat the seal)

• Turn off power at the breaker; open the door and inspect the seal for tears, flattening, or hard spots.
• Clean the seal channel and mating surfaces with warm water and mild dish soap; remove grit that can prevent sealing.
• Start at the top center and press the gasket into the channel a few inches at a time; keep the “bulb” facing outward.
• Work down both sides evenly; avoid stretching the gasket because it can shrink back and pull out later.
• Close and latch the door; keep it closed for at least 2 to 4 hours (overnight is ideal) to help the gasket conform.
• Run a short cycle and check for drips at the corners and along the bottom edge.

If the leak is at the bottom of the door

Bottom-edge leaks are often caused by a worn lower seal rather than the perimeter gasket.

Leak location	Most common cause	What to do next
Bottom center or bottom corners	Lower door seal not sealing	Inspect and replace the lower seal if it is split or permanently deformed; consider dishwasher door seal, lower WPW10497235
One corner only	Door not level or door rubbing	Check leveling and centering; adjust legs and alignment per the KUDS35FXSS8 installation guide
Random drips during wash	Oversudsing or spray deflection	Use dishwasher detergent only; reduce rinse aid if foaming; confirm racks are not blocking the spray arm

Why it matters

A properly seated door seal keeps wash water inside the tub, protects the door insulation and wiring, and prevents moisture damage around the cabinet opening. Even a small twist or gap in the gasket can cause corner leaks.

This page is for the KitchenAid KUDS35FXSS8 undercounter dishwasher, not a KitchenAid stand mixer; for mixer attachment care, use your mixer’s Use and Care Guide. For KUDS35FXSS8, the items to keep out of the dishwasher are non-dishwasher-safe accessories and any dishwasher components that are damaged or not meant to be washed in-cycle; confirm handling and safety steps in the KUDS35FXSS8 installation guide.

What you should not put in the KUDS35FXSS8 dishwasher

• Wooden items (cutting boards, wooden utensils)
• Cast iron and carbon steel cookware
• Fine crystal, delicate china, and items with metallic trim
• Nonstick pans with loose or damaged coating
• Insulated cups, sealed containers, or anything labeled “hand wash only”

Dishwasher parts: what is safe to wash vs. what is not

Most removable dishwasher parts are designed to be rinsed or cleaned, but some should be hand-cleaned only and never run loose in a cycle.

Item	Best cleaning method	Why
Racks and tines	In place during normal cycles	Designed for wash exposure
Spray arms	Hand-rinse; clear holes	Prevents clogs and poor wash performance
Filters/screens	Hand-clean with warm water	Keeps drainage and circulation strong
Loose small rack clips/wheels	Hand-clean; reinstall securely	Prevents damage and pump obstruction

If you meant “dishwasher parts that should not go through a cycle”

Use these practical rules for KUDS35FXSS8:

• Do not run the dishwasher with broken rack parts that can fall off
• Do not run with a missing or damaged filter; debris can reach the pump
• Do not run if the spray arm is cracked or rubbing; it can stop rotation
• Do not run if the door seal is torn and leaking

If you are replacing worn rack hardware, match parts by model; common rack repairs include the dishrack adjuster kit W10712394 and the dishwasher lower dishrack wheel assembly W10195416V.

Why it matters

Keeping unsuitable items and loose/broken components out of the wash protects the pump, spray system, and racks; it also improves cleaning and helps prevent leaks.

KUDS35FXSS8 is a KitchenAid undercounter dishwasher, not an oven, so the serial number on this unit dates the dishwasher. Use the serial number from the rating label and the format guidance in your KitchenAid documentation; start with the KUDS35FXSS8 installation guide for label location.

Confirm the appliance you are dating

Before decoding anything, match the model number on the rating label to the appliance.

• KUDS35FXSS8 (prefix KUD) = dishwasher
• Wall ovens and ranges use different model prefixes and often different serial formats
• The model number and serial number are printed together on the rating label
• Use the serial from the same label as the model number (don’t mix labels from different appliances)

Where to find the serial number on this dishwasher

KitchenAid dishwashers commonly place the rating label where it’s visible when the door is open.

• Along the inner door edge (left or right side)
• On the tub frame near the door opening
• Occasionally on the side of the door itself

For exact placement and installation clearances, use the KUDS35FXSS8 installation guide.

How KitchenAid serial numbers typically encode the date

KitchenAid serial formats vary by production run, but these patterns are common across many KitchenAid appliances.

• A specific character position can represent a year code
• Another character position can represent a month or week code
• Some formats use day-of-year (001 to 365) plus a 2-digit year

Common pattern	What you look for	What it tells you
Year/month code	Letter or digit in a set position	Build month and year
Week/year code	Two digits for week plus year code	Production week and year
Day-of-year code	001-365 plus 2-digit year	Exact day in year and year

Why it matters

Knowing the manufacture date helps us match the correct KitchenAid parts and revisions for your KUDS35FXSS8 dishwasher, especially when components like the drain pump, heater, or rack hardware changed during a production run.
