Frequently Asked Questions

Rapid Fast Flow Electric Water Heater series equips with double inner tank and two independent heating elements. When user starts to use hot water, the hot water of the left inner tank will be used first. If water temperature does not reach the temperature set by the user, the heating element will be activated, and the upper indicator light will be on first

When water temperature in the left inner tank reaches the temperature set by the user, the lower indicator light will be on, indicating that the heating element of the right inner tank has started to replenish heat.

Check the location of leakage. If water is dripping from Pressure & Temperature Relief Valve (PTV):

1. It's normal as PTV is releasing pressure and temperature.

2. If water dripping from PTV is more frequent than usual, it is suggested to set temperature at a lower level (between 2 & 3). If there is no improvement, contact us for an inspection.

3. If water dripping from PTV is in large amount and at fast speed, inspection is needed as the inlet water pressure and boiling pressure has exceeded normal.

4. If PTV is leaking when boiler is not activated, must contact us for inspection, as inlet water has exceeded normal pressure.

If water is leaking from the bottom of the heater:

If the indicator light is on (meaning heater is under normal operation), check whether the tap or pipe is blocked or damaged. Customer should contact a professional for an inspection and repairs.

The Rapid Fast Flow Electric Water Heater is not out of order. Cold water does not go through the inside of the heater. There is no cold water mostly because the tap is broken or the water pipe is clogged. Contact the Repairs & Customer Service Centre for inspection and repair.

The water heater is noisy due to gasification. Release hot water inside the heater to force out the air. Procedure: 1. Turn off power supply; 2. Release the hot water; 3. Turn off the tap after 30-60sec; 4. Repeat the above process 3-4 times

Check the power supply: 1. Restart the power if there is a short circuit of electric box. 2. If the Power Switch (Cooker Switch) doesn't light, customer should contact a professional for inspection and repairs. 3. If the Power Switch (Cooker Switch) lights but the indicator light doesn't, inspection should be arranged for repairs. 4. Under normal operation, hot water supply is only available after the indicator light goes out.

Water inside the tank flows away through the pipe during water shortage. When water supply resumes, turn on the hot water tap and let water flow through the shower head before switching on the power. The heating element will be damaged if it is not submerged under water.
