Washer-dryer displays incorrect water temperature (e.g., hot when set to cold).

Safety first: Turn off water supply and unplug the unit before swapping hoses or accessing valves.

Steps to correct:

• Verify hose connections: Ensure the hot water hose is connected to the hot inlet and the cold hose to the cold inlet on the back of the unit. Swap if reversed.
• Test temperature: Run a short fill on cold-only and feel the water entering the drum. It should be cold or cool.
• Inspect inlet valve: If hot water enters during a cold fill, the water inlet valve assembly may be leaking internally and should be replaced.
• Check thermistor (advanced): If temperatures are inconsistent, test the inlet thermistor as described in temperature sensor errors.

Correct water temperature is important for fabric care and detergent performance.
