More Details


The water of the Instantaneous Water Heater remains cold and its digital display screen does not light up. Why?
The master fuse may have tripped. Try to replace or reactivate the fuse. It is also possible that the safety pressure/thermal cut-out has tripped. Please contact the Repairs & Customer Service Centre.
Can I hire a qualified technician to do water heater installation by myself if I know exactly which model to replace my old one?
It depends on which type of water heater you are going to replace. On-site sighting is necessary if your old water heater is gas-typed.
Why is the Instantaneous Water Heater displaying the error code "Er"?
Error code "Er" indicates that the control system has switched off. Switch off the fuse and turn it on again. If "Er" is still displayed, please contact the repairs & customer service centre.
What is the best way to clean and maintain the Instantaneous Water Heater?
Wipe the plastic surface and parts with a damp cloth. To ensure a stable water supply, detach and clean the outlet parts (tap aerators and shower heads) regularly. Have the electrical and plumbing components inspected by authorized technicians on a regular basis to ensure safety.
The Instantaneous Water Heater displays the error code "NO" and is not responding to the remote control. Why?
The distance between the remote control and the water heater has exceeded the transmission range. Also, the signal of the remote control may be disturbed by other radio emitters.
