Whirlpool Washing Machine: not heating

Professional Repair Guide

What is this symptom?

Is your Whirlpool washing machine running but the water isn't heating during wash cycles? This issue typically arises in models with built-in heating, often due to a faulty heating element, incorrect cycle selection, or a malfunctioning temperature sensor. Discover effective solutions to restore your washer's heating functionality.

Urgency: Medium

Important Tips for Whirlpool Models

  • Some Whirlpool HE washers with internal heaters require proper cycle settings to engage heater; not all cycles call heater even if warm/hot selected.

Possible Causes

Faulty heating element

How to Identify: Water stays cold during wash in all cycles that should heat; continuity test with multimeter shows open circuit on heating element. Warm/hot water cycles never produce warm water.

Part: Heating element

Failed temperature sensor/thermostat or control board not activating heater

How to Identify: Multimeter readings out of spec on temp sensor; control board doesn’t send voltage to heater even when element is OK; error codes related to temp. Some Whirlpool models use thermistors rather than simple thermostats.

Part: Temperature sensor/thermostat or control board

Incorrect cycle selection or incoming water temperature setup (no internal heater call)

How to Identify: Warm water not selected; machine configured to use incoming hot water only; hoses swapped cold/hot. Not a failed component but misuse or configuration.

Part: User settings / water source
