Dishwasher Not Drying Dishes: Causes & Fixes

Missing or insufficient rinse aid is the most consistently cited cause of poor drying: it reduces the surface tension of water so it sheets off and evaporates instead of beading; documented by GE, Samsung, and Frigidaire.

Before you work on your dishwasher

  • Power: Unplug the dishwasher or switch off its circuit breaker before removing panels or touching wiring.
  • Water: Turn off the water supply valve before disconnecting hoses or the inlet valve.
  • Heat: Water and the heating element can be hot right after a cycle; let the dishwasher cool first.
  • Sharp debris: Wear gloves when reaching into the filter or sump; broken glass often collects there.
  • Stop: If you smell burning, see smoke or sparks, or find water near wiring, switch off the breaker and call a technician.
  • Disconnect power before accessing internal dishwasher parts: Unplug the dishwasher or switch off the circuit breaker that powers it before removing panels, the filter, or the drain pump cover, or before reaching into the sump.
  • Heavy appliance: two-person lift: A dishwasher is heavy and can tip. Do not pull it out of the cabinet, tilt it, or lift it by yourself; get a second person to help.
  • Shut off the water supply before disconnecting hoses: Turn off the water supply before disconnecting the drain hose, siphon connection, or water inlet, or before pulling the dishwasher out for service.
  • Hot water and steam scald risk: Open the dishwasher door carefully during or right after a cycle. Hot water or steam can escape and cause burns; wait until water noises stop and steam subsides before fully opening the door.
  • Hot water supply temperature: Keep the water heater setting for the dishwasher supply at or below 149°F (65°C); hotter water can cause severe burns.

Why your dishwasher is not drying dishes

  1. Rinse aid empty or set too low: Missing or insufficient rinse aid is the most consistently cited cause of poor drying: it reduces the surface tension of water so it sheets off and evaporates instead of beading; documented by GE, Samsung, and Frigidaire. Difficulty 1/5.
  2. Heat-assisted dry option not selected: Not selecting a heat-assisted dry option (Heated Dry, Power Dry, or a forced-air drying cycle) instead of a no-heat Air Dry setting, or choosing a Quick/30-Minute wash that skips extended drying, leaves dishes wetter; documented by GE and Frigidaire. Difficulty 1/5.
  3. Improper loading or hard-to-dry item types: Plastic items, concave items like bowls and mugs, and items loaded so they touch or overlap trap water and dry poorly regardless of the dishwasher's condition; documented by GE, Samsung, and Frigidaire. Difficulty 1/5.
  4. Incoming water not hot enough: Water entering the dishwasher below roughly 120°F does not get hot enough to evaporate efficiently during drying; documented by GE and Frigidaire. Difficulty 2/5.
  5. Cycle interrupted before drying completed: A cycle that stopped mid-way, often due to an error code or an item bumping the door open, ends before the drying phase completes; documented by Samsung. Difficulty 1/5.
  6. Dishwasher connected to cold water line: A dishwasher connected to the household cold water line instead of hot never gets water hot enough for the condensing-dry process to work well; documented by Samsung. Difficulty 2/5.
  7. Heating element failed: A failed heating element means the water and the dishwasher's interior never get hot enough to evaporate water off the dishes, even with rinse aid and a heat-dry option selected; documented by iFixit. Difficulty 3/5.
  8. Vent door/flap damaged or obstructed: A dishwasher's motorized vent door/flap that is damaged or obstructed will not open during the dry cycle, trapping steam inside instead of venting it out; documented by iFixit. Difficulty 2/5.
  9. Vent fan motor failed: If the vent door opens correctly but the vent fan motor has failed, most of the steamy air stays trapped inside instead of being blown out; documented by iFixit. Difficulty 3/5.
  10. Heating wiring, thermostat, limit switch, or control board fault: If the heating element itself tests fine, iFixit documents that a loose/failed wiring connection to the heating element, a failed thermostat, a failed limit switch, or a failed control board can each prevent the water from heating enough to dry dishes. Difficulty 1/5.

Find the cause for your dishwasher

Before anything else: do you smell burning or see smoke, scorch marks, or melted plastic inside the dishwasher?

Step-by-step checks for a dishwasher not drying dishes

Check the cycle and dry option selected

About 2 minutes

  1. Check which cycle was run.
  2. Confirm Heated Dry / Power Dry / forced-air option was selected rather than Air Dry or a Quick/30-Minute cycle.

Check whether the door was opened after the cycle

About 1 minutes

  1. Note how soon the door was opened after the cycle ended.
  2. Note whether it was left fully closed.

Check for an interrupted cycle

About 5 minutes

  1. Check the display or app history for an error code from the last cycle.
  2. Check whether an item could have bumped the door open mid-cycle.

Check the rinse aid level

About 2 minutes

  1. Open the dishwasher and check the rinse aid dispenser's fill indicator.

Check incoming water temperature

About 10 minutes

  1. Run the kitchen faucet nearest the dishwasher on hot before a cycle.
  2. Check whether the water reaches roughly 120°F or hotter.

Review the load and item types

About 3 minutes

  1. Check for plastic items.
  2. Check that concave bowls/mugs are angled or upside down.
  3. Check whether items are touching or overlapping.

Check the water inlet connection

About 10 minutes

  1. Trace the dishwasher's water inlet line back to the shutoff valve under the sink.
  2. Confirm it is connected to the hot water line, not the cold line.

Inspect the vent door/flap

About 5 minutes

  1. Locate the small motorized vent door/flap, often near the top front of the tub or door.
  2. Check that it is not damaged, stuck, or blocked.

Test the heating element

About 30 minutes

  1. Let the dishwasher cool completely.
  2. Unplug the dishwasher or switch off its circuit breaker, and shut off the water supply.
  3. Measure resistance across the heating element terminals with a multimeter (roughly 8-30 ohms is normal; infinite resistance means it has failed).

Test the vent fan motor for continuity

About 25 minutes

  1. Unplug the dishwasher at the plug or breaker and shut off its water supply.
  2. Remove the vent fan motor.
  3. Test it for continuity with a multimeter.

Test heating wiring, thermostat, and limit switch

About 30 minutes

  1. With power disconnected and the water supply off, check wiring connections to the heating element for looseness.
  2. Test the thermostat for continuity (should read near zero ohms).
  3. Test the limit switch for continuity.

How to fix a dishwasher not drying dishes

Fill the rinse aid dispenser and adjust the dosage

About 5 minutes · Difficulty 1/5

  1. Fill the rinse aid dispenser.
  2. If spotting or wetness persists after a few cycles, raise the dosage setting one level and retest.

Improve dish loading and manage hard-to-dry items

About 5 minutes · Difficulty 1/5

  1. Angle bowls, mugs, and other concave items so water can drain off.
  2. Keep plastic items on the top rack, expecting them to dry more slowly.
  3. Space items so they do not touch or overlap.

Open the door after the cycle finishes

About 1 minutes · Difficulty 1/5

  1. Open the dishwasher door about 1 inch (or several inches per GE, if not using heated dry) within about an hour of the cycle ending.
  2. Let warm, moist air escape before fully unloading.

Clear the interruption and rerun a full cycle

About 90 minutes · Difficulty 1/5

  1. Clear any error code per the owner's manual.
  2. Reload dishes so nothing can hit the door.
  3. Run a full cycle again.

Select a heat-assisted dry cycle

About 2 minutes · Difficulty 1/5

Clear or replace the vent door/flap

About 20 minutes · Difficulty 2/5

  1. Clear any obstruction from the vent door/flap.
