None Dishwasher: not heating, not drying

Professional Repair Guide

What is this symptom?

Is your dishwasher completing cycles but leaving dishes wet? If your dishwasher is not heating water or effectively drying dishes, it could be due to low rinse aid, incorrect cycle selection, or a faulty heating element. Explore common causes and solutions to restore optimal performance.

Urgency: Medium

Possible Causes

Low or missing rinse aid leading to poor drying performance

How to Identify: Dishes are wet but the dishwasher otherwise functions normally and there’s no heat smell; rinse aid compartment is empty or low.

Part: Rinse aid dispenser and rinse aid level

Incorrect cycle selection

How to Identify: Selected wash cycles skip heated drying or use low heat/eco settings; check user manual for drying settings.

Part: Dishwasher cycle settings

Faulty heating element (older models)

How to Identify: No heat felt during drying cycle; multimeter shows open circuit or visible damage to element; dishware remains cold at end of cycle.

Part: Heating element

Malfunctioning high‑limit thermostat or temperature sensor

How to Identify: Dishwasher shuts off heat prematurely or doesn’t reach adequate drying temperature, often without user‑visible fault codes.

Part: Thermostat/temperature sensor

Blocked vent or condensation drying vent issues

How to Identify: Vent area blocked by debris or poorly positioned dishes lowering airflow; persistent wetness after cycle.

Part: Drying vent
