Washer-dryer combo displays error code 12; water temperature seems incorrect or cycle stops unexpectedly.

Safety first: Turn off power and water supply before accessing internal components.

Steps:

• Verify hose connections: Confirm that the hot water hose is connected to the hot inlet and cold to cold on the Café combo. Reverse connections can cause temperature errors.
• Run a cold-only cycle: Select a cold wash and see if the error appears. Then try a hot wash. Note which setting triggers the code.
• Inspect thermistor: Access the wash tub area and locate the wash water temperature sensor (thermistor). Check for loose or corroded connectors and reseat them.

When to call a technician: If code 12 persists, the thermistor or control board may be defective and should be tested with a multimeter by a technician.
