KitchenAid KDFE104KPS2 dishwasher Parts

A KitchenAid dishwasher typically lasts 10 years. For your KitchenAid KDFE104KPS2, good loading habits, regular cleaning, and fixing small leaks or drain issues early are what most often determine whether it reaches the 9 to 14 year range.

Most KitchenAid dishwashers fall into this range:

We recommend these habits for the KDFE104KPS2:

• Clean the filter area and remove debris regularly (prevents pump and drain strain).
• Rinse out and inspect the lower spray arm holes for clogs (improves cleaning and reduces rewash cycles).
• Wipe the door sealing surfaces so the seals seat correctly.
• Run a dishwasher cleaner cycle periodically to reduce grease and mineral buildup.
• Keep the drain path clear (air gap or high loop, disposer inlet, and hose routing).

When a dishwasher starts underfilling, leaking, or not draining, it often comes down to a few serviceable parts. On this model, these are common suspects:

• Water fill problems: fill valve assembly W11434044
• Overfill protection issues: dishwasher float switch W11545764
• Leaks at the door or tub edge: gasket-tub,d W11483553
• Not draining or slow drain: hose-drain,e W11414944

A dishwasher near the end of its typical lifespan often shows up as longer cycles, poorer cleaning, standing water, or intermittent leaks. Addressing those early can prevent secondary damage to the sump, wiring, and door components.

To tell how old your KitchenAid KDFE104KPS2 dishwasher is, we use the serial number to decode the manufacturing date (year and week). On dishwashers, the serial tag is typically on the tub frame or door area; once you have it, you can match the date code format used for KitchenAid-built units.

Check these common locations on a KitchenAid dishwasher:

• Along the top edge of the inner door (open the door and look up)
• On the left or right side of the inner door frame
• On the tub rim near the latch area
• Sometimes behind the lower access panel (toe-kick)

Write down both the model number (KDFE104KPS2) and the serial number exactly as shown.

Most KitchenAid dishwashers use a serial format that includes a manufacturing week and year. The exact positions can vary by production run, so we recommend decoding it by pattern:

• Look for a 2-digit week (01 to 52) embedded in the serial
• Look for a 1-digit or 2-digit year indicator near the week code
• Confirm the result makes sense compared to when the dishwasher was installed or purchased

Knowing the build date helps us choose the right repair approach for your KitchenAid KDFE104KPS2, especially when diagnosing age-related issues like leaks, no-fill, or no-drain symptoms.

If your dishwasher is acting up while you’re checking the serial tag, these model-relevant parts are commonly involved:

• Fill valve assembly W11434044 (no fill, slow fill)
• Dishwasher float switch W11545764 (overfill protection, fill problems)
• Hose-drain,e W11414944 (drain issues, leaks under the unit)

For a KitchenAid dishwasher like model KDFE104KPS2, the most commonly replaced parts are the ones that control water flow, sealing, washing action, and starting. In real-world repairs, we most often see issues with inlet/valve parts, door seals, spray arms, and door latch components.

These parts wear out from heat, detergent, hard-water mineral buildup, and normal mechanical use:

• Water inlet valve or fill valve (no fill, slow fill, overfill)
• Door seals and gaskets (leaks at the door or along the tub edge)
• Spray arms (poor cleaning, clogged jets, noisy spraying)
• Door latch and switches (won’t start, stops mid-cycle)
• Drain hose and clamps (leaks under the unit, drain problems)
• Control board or electronic control (dead unit, erratic operation)

When symptoms match, these model-specific parts are frequent fixes:

We recommend these fast checks because they often solve the problem without replacing anything:

• Clean the spray arm holes and the filter area for food debris.
• Confirm the water supply valve under the sink is fully open.
• Check for kinks in the drain hose and a clogged sink/disposer connection.
• Inspect the door seal for tears, flattening, or detergent residue.
• Make sure the door closes firmly and the latch engages.

Replacing the right part restores proper water fill, wash pressure, and sealing. That prevents leaks, improves cleaning and drying performance, and helps avoid repeat breakdowns caused by running the dishwasher with low water flow or poor drainage.

The most common problems we see on KitchenAid dishwashers like model KDFE104KPS2 are poor cleaning, not draining, door-area leaks, and a dishwasher that will not start. Most start with maintenance, loading, and drain routing; then move to water-in and door-safety parts.

• Not cleaning well: clogged spray arm holes, blocked water feed, heavy soil in the sump area
• Not draining: kinked drain hose, clogged drain path, restriction at the sink or disposal connection
• Leaking at the front: debris on sealing surfaces, oversudsing, worn lower door seal
• Will not start: door not latching fully, door switch not closing, control settings
• Not filling: supply valve closed, inlet restriction, failed inlet valve

• Clear debris from the bottom of the tub and around the sump area.
• Confirm the lower spray arm spins freely and holes are open.
• Verify the drain hose has a proper high loop and is not kinked.
• Wipe the door sealing surfaces clean; use only dishwasher detergent.
• Run hot water at the sink for 30 to 60 seconds before starting a cycle.

Dishwashers rely on correct water level, strong spray, and a tight door seal. One restriction (inlet, spray, or drain) can cause dirty dishes, long cycles, and standing water.
