KitchenAid KDTE104ESS2 dishwasher Parts

For the KitchenAid KDTE104ESS2 dishwasher, the most common issues we see are not draining well (water left in the tub) and not cleaning well (food left on dishes). These problems are often tied to filter maintenance, spray-arm blockage, or a drain-path restriction described in the KDTE104ESS2 user guide.

• Standing water after a cycle: clogged filter area, drain hose restriction, or a weak drain pump
• Gritty dishes or food debris: dirty filters, blocked spray arm holes, or poor loading
• Cloudy glassware/film: hard water, detergent issues, or low rinse aid setting
• Won’t start or stops: door not latched, control lock, or cycle interruption
• Poor drying: rinse aid empty or Heat Dry not selected

1. Check filters: Make sure the upper filter assembly is locked and the lower filter is seated; rinse under running water.
2. Confirm spray arms spin freely: Dishes or tall items can block rotation.
3. Run hot water at the sink first: KDTE104ESS2 is designed around hot water entering the tub.
4. Use rinse aid and Heat Dry: This model’s guide notes rinse aid is essential for best drying.
5. If it won’t drain: Check the sink/disposer connection and any air gap for blockage.

If the dishwasher consistently won’t drain after you’ve cleaned filters and verified the drain path, the drain pump is a common suspect on many KitchenAid designs. For this model, the compatible replacement is the dishwasher drain pump WPW10348269.

On KDTE104ESS2, a partially blocked filtration or drain system can reduce wash pressure and leave soil behind, and it can also cause water to remain in the tub. Keeping filters clean helps prevent repeat clogs and improves cleaning performance.

The KitchenAid KDTE104ESS2 is a standard 24-inch class built-in dishwasher, but the installation opening is more precise than “24 inches.” Plan for a minimum opening width of 23 7/8 inches and an opening depth of about 24 3/4 inches, with height adjustable around the mid-34-inch range; see the KDTE104ESS2 installation guide.

These are the cabinet-opening dimensions that matter most for fitting the KDTE104ESS2 under a countertop.

• Minimum opening width: 23 7/8 in (23.875 in)
• Opening depth: about 24 3/4 in (varies by handle and panel style)
• Opening height: typically around 34 1/2 in, with leveling adjustments
• Door clearance: allow space for the door to open without hitting adjacent cabinets
• Utility routing: keep the water line, drain hose, and wiring in the recommended zones so nothing pinches

Even small differences like 3/4 inch of depth can determine whether the dishwasher sits flush, the door closes smoothly, and the drain hose and power cord route safely. Using the model-specific installation dimensions helps prevent fit and alignment problems.

KitchenAid does not list an “average lifespan” for the KitchenAid KDTE104ESS2 dishwasher in the model’s documentation, so we can’t confirm a model-specific number. In general, dishwasher life varies widely based on use, water quality, and maintenance; our best guidance is how to maximize service life using the KDTE104ESS2 user guide.

The KDTE104ESS2 user documentation focuses on operation, cleaning, and troubleshooting rather than a guaranteed service-life figure.

• It explains filter system maintenance (upper and lower filters)
• It recommends rinse aid for best drying performance
• It notes efficient dishwashers often run longer cycles to save water and energy
• It includes a problem solver for issues like poor drying, spotting/filming, and draining

Across KitchenAid dishwashers, longevity is most affected by how hard the machine has to work and whether small issues are corrected early.

• Hard-water mineral buildup and filming
• Filters left dirty or not locked in place
• Spray arms blocked by tall dishes or improper loading
• Using the wrong detergent type (suds and overflow issues)
• Small leaks or slow draining that are ignored

These steps reduce strain on the pump, heater, and seals.

• Clean/rinse the filters when you see debris or dishes feel gritty
• Run hot water at the sink before starting a cycle
• Use rinse aid and adjust the setting if drying is poor
• Keep the door sealing surfaces clean and free of food residue
• Address slow draining promptly

Because KDTE104ESS2 doesn’t have a published lifespan target, focusing on filtration, proper detergent and rinse aid use, and early leak or drain fixes is the most reliable way to get the longest practical service life.
