Leakage is found on my water heater. How to fix it?

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 faster speed, inspection is needed as the water supply pressure and boiling water pressure is higher than normal. 4. If there is water dripping from PTV when the appliance is off, inspection is needed as the incoming water pressure is higher than normal. There is leakage at the bottom of heater: 1. If water dripping from the inlet, outlet and the bottom edge, inspection should be arranged for repair. 2. If there is water dripping from the joints of inlet & outlet, customer should contact a professional for an inspection and repairs. There is leaking from shower head and tap: 1. Customer should contact a professional for a inspection and repairs.

Why is my Rapid Fast Flow Electric Water Heater not producing any cold water but only hot water?

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.

There is no hot water supply from my Rapid Fast Flow Electric Water Heater – Shower Type after water shortage. Why?

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.

Why is the water heater making noise?

The noise comes from the operating sound of the heating elements. Also, when the water pressure is unstable, the water heater tends to make noise.

Why does hot water drip off from the showerhead after my Rapid Fast Flow Electric Water Heater-Shower Type (GPNB-6SSL) is turned off?

This is absolutely normal because this water heater is unvented-type. Due to thermal expansion, small amount of water may drip off from the showerhead when the inner tank temperature is very high.
