The washer could not heat the water correctly or the water temperature is outside the expected range. It applies to models with an internal heater.

Likely causes

Listed from most to least common.

1. Hot and cold inlet hoses connected the wrong way round
2. Faulty heating element
3. Faulty temperature sensor (thermistor)
4. Loose wiring to the heater

How to fix the HC code

Unplug the washer or switch it off at the breaker before removing any panel or filter.

1. 1

   Step 1: Check the hose connections

   The hot tap should connect to the red or H port and the cold tap to the blue or C port. Swap them if they are reversed.

2. 2

   Step 2: Reset the washer

   Unplug the washer for one minute, plug it back in and run a warm cycle.

3. 3

   Step 3: Try a cold cycle

   If cold washes work but warm or hot washes show the code, the heater or its sensor is the likely cause.

You'll need: Multimeter (for testing the heater), phillips screwdriver.
