Safety devices will keep monitoring the operation status of appliance. If a fault occurs, a fault code will
be displayed on the temperature display. Please quote the code displayed when contacting customer
service.
In general cases, fault may be eliminated by turning off and then turning on the hot water tap again. If
the fault cannot be eliminated, try to turn off the power supply and wait for 10 seconds before turning on
the appliance again. If the fault still persists, please contact Customer Service Hotline on 2232 1111.
In cold and humid weather, cloudy mist may occasionally emerge from the flue terminal. The white mist
is the condensate of water vapour in flue gases. This is a normal phenomenon.
