KitchenAid Dishwasher Not Drying Dishes: 6 Fixes

Common Symptoms

• Dishes are wet or damp when the cycle ends and the door is opened
• Plasticware is especially wet while glassware and ceramic dry reasonably well
• Dishes feel cool to the touch at the end of the cycle — no residual heat
• Inside of the tub has water droplets on the walls and roof
• Energy Saver dry selected but customer expects heated dry performance
• Previously dried well but now leaves everything wet
• Top rack items dry but bottom rack plastics are always soaked

Most Likely Causes

1. 1

   Rinse Aid Dispenser Empty (WPW10082871)

   Rinse aid is the most important factor in KitchenAid dishwasher drying performance — far more important than the heating element alone. Rinse aid (dispensed from WPW10082871) lowers the surface tension of water, causing it to sheet off dishes in thin films that evaporate instantly rather than bead up and stay wet. An empty rinse aid dispenser is the #1 cause of wet dishes on every KitchenAid model. The dispenser indicator (a window on the door) turns from blue to clear/white when empty. Fill to the MAX line with any brand of rinse aid — Finish Jet-Dry and Cascade Rinse Aid are both effective.

2. 2

   Heated Dry Setting Not Selected

   KitchenAid KDTM354, KDPE234, KDFE104, and KDTE254 models offer multiple dry options: Heated Dry, ProDry (KDTM354/KDTE254), Extended ProDry, and Heat Off or Energy Saver. Heat Off and Energy Saver cycles do not activate the heating element after the final rinse — dishes air-dry passively and will be noticeably wetter than with Heated Dry selected. Check which dry option is selected on the control panel. Press the Heated Dry or ProDry button before pressing Start.

3. 3

   Energy Saver Mode Bypasses Heated Dry

   The Energy Saver or 'Heat Off' dry cycle is an intentional feature that reduces electricity consumption by skipping the heated dry phase entirely. When selected, the dishwasher finishes the final rinse at elevated temperature and then opens the door slightly (on models with auto-open door release) or simply lets dishes air dry. Drying performance with Energy Saver is inherently inferior to Heated Dry — plastics especially will remain wet. If drying performance is important, always select Heated Dry or ProDry.

4. 4

   Failed Heating Element (WPW10352614)

   The heating element (WPW10352614) is a resistive coil that runs around the base of the tub. It heats both the wash water during the cycle and the air inside the tub during the Heated Dry phase. A broken element tests open (OL) on a multimeter — a working element should measure 10–30 ohms of resistance. A failed element means no heat during the dry cycle, and dishes that are cool and wet when opened. Visually, a burned element may show a break in the coil or scorch marks.

5. 5

   Failed High Limit Thermostat (WPW10131825)

   The high limit thermostat (WPW10131825) is a safety device mounted near the heating element that cuts power to the element if the tub temperature exceeds a safe threshold. If this thermostat has failed in the open position — a common fault mode — it permanently interrupts the heating element circuit even during normal operating temperatures. The thermostat tests open on a multimeter when it has failed, and the heating element will test normal resistance (10–30Ω) but won't heat because power is blocked upstream.

6. 6

   Vent Fan Motor Failure (WPW10134009)

   KitchenAid KDTM354 and KDTE254 ProDry models use a vent fan motor (WPW10134009) to actively push moist air out of the tub during the dry phase, dramatically improving drying performance especially for plastics. If the fan motor fails, the ProDry cycle runs silently — you won't hear the fan — and drying performance drops significantly. The vent fan is mounted in the vent assembly on the inner door. It can be tested for continuity at its motor terminals with a multimeter.

Quick DIY Checks

1. 1Check the rinse aid level first: open the dishwasher door and locate the rinse aid dispenser — a round cap on the inner door, usually to the right of the detergent dispenser. Open the cap and look inside: the compartment should be full of rinse aid (a blue-tinted liquid). The indicator window on the cap turns clear/white when empty. Fill to the MAX line. Do not overfill. Run a full Heated Dry cycle and check results. Rinse aid alone fixes 40–50% of drying complaints on KitchenAid dishwashers.
2. 2Confirm Heated Dry is selected — not Energy Saver: close the door and look at the cycle option lights on the control panel. On KDTM354 and KDTE254 models, cycle through the dry options and select 'ProDry' or 'Extended ProDry' for maximum drying. On KDPE234 and KDFE104 models, press the 'Heated Dry' button until its indicator light illuminates. Never select 'Heat Off' or 'Energy Saver' if dry dishes are important. Start the cycle and note whether the tub feels warm when the cycle finishes (open the door 30 seconds after the cycle ends — warm moist air is normal with Heated Dry active).
3. 3Improve loading to maximize drying: plastic items hold water on flat surfaces regardless of the heating element's condition. Always place plastic containers on the bottom rack with openings angled downward and toward the center — this allows water to drain off. Never stack plastic lids flat. Cups and bowls on the top rack should be inverted and tilted so water cannot pool in recesses. Leave at least 1 inch between items for air circulation. A correctly loaded dishwasher with fresh rinse aid dries far better than a poorly loaded one with a working element.
