KitchenAid Dishwasher Not Drying — What’s Happening
When a KitchenAid dishwasher is not drying, you are typically dealing with a performance complaint rather than a fault code. KitchenAid treats this as an issue with cycle settings, rinse aid, dish loading, or a failed heating or drying component. Some KitchenAid models may also display error code 10-3, which specifically indicates a drying fan failure.
For the generic complaint, KitchenAid directs you to first check whether a heated-dry option like Heat Dry, Extended Dry, Pro Dry, or Door Open Dry was selected, whether rinse aid is present and adjusted correctly, and whether dishes are loaded to drain properly. KitchenAid also recommends running the Sanitize cycle to verify the heating element is working. A steady Sanitize LED at the end means the heater is okay, while a blinking Sanitize LED suggests a heating-element problem.
Most Likely Causes
- Wrong cycle or option selected Heat Dry, Extended Dry, Pro Dry, or Door Open Dry option was not turned on, so the dishwasher skipped the heated-dry phase.
- Rinse aid missing or misadjusted Rinse aid dispenser is empty or the rinse-aid setting is too low, preventing water from sheeting off dishes properly.
- Poor loading or nesting Dishes, plastics, or glasses are overlapped, nested, or positioned flat instead of angled, so water pools and cannot drain or evaporate.
- Failed heating element Heating element is open or damaged, so the dishwasher cannot generate heat for drying.
- High-limit thermostat or thermal fuse open High-limit thermostat or thermal fuse has tripped or failed, cutting power to the heating element.
- Control board or relay failure Control board or relay is not sending power to the heating element, even when a heated-dry option is selected.
- Drying fan failure (code 10-3) On models with a drying fan, the fan motor has failed or the vent path is blocked, preventing airflow and triggering error code 10-3.
How to Diagnose and Fix
- Confirm Heat Dry, Extended Dry, Pro Dry, or Door Open Dry option is turned on for the cycle you are running.
- Check the rinse-aid dispenser and fill it if empty, then adjust the rinse-aid setting to a higher level and run a test load.
- Inspect dish loading and reposition any nested, overlapped, or flat items so water can drain and air can circulate.
- Run the Sanitize cycle and observe the Sanitize LED at the end. A steady LED means the heater is working. A blinking LED indicates a heating-element problem.
- If Sanitize completes normally but dishes are still wet, run a 1-Hour wash with Heat Dry and check that dishes are warm when the cycle finishes. Cool dishes mean the heater is not operating.
- If the heater is not working, unplug the dishwasher, remove the lower access panel, and test the heating element, high-limit thermostat, and thermal fuse for continuity. Check wiring and connectors for opens, corrosion, or heat damage.
- If your model displays error code 10-3, access the drying fan motor, inspect the vent area for blockage, and test the fan motor for continuity. Replace the fan motor if it fails.
- If all components test good but the heater still does not receive power, check the control board relay path and replace the control board if the relay is failed or the board is not sending the signal.
Parts You Might Need

When to Call a Pro
Call a pro if you are not comfortable working with live voltage or removing panels to access internal components. If you have verified cycle settings, rinse aid, and loading but the dishwasher still will not dry, a technician can safely test the heating element, thermostat, control board, and fan motor circuits. Heating-element and control-board replacement require disconnecting power and water, removing spray arms and racks, and working inside the tub and base, so professional service is recommended if you are uncertain about any step or if error code 10-3 is displayed.
