* Error Modes
1. "H2": Open/Short error in washer temperature sensor
(Defective sensor or disconnection)
2. "H4": Overheated washer temperature sensor
(The sensor temperature turns out to be 95°C or
higher)
3. "H5": Overheated washer temperature sensor
(The water temperature is 45°C or higher in the
Delicate program)
4. "H6": Malfunction of water heater
(The water temperature fails to rise by 2°C within 30
minutes after the heater starts running)
5. "H8": Overheated water heater
(The water temperature rises by 6°C or more within 30
seconds after the heater starts running due to the lack
of water in tub)
