Troubleshooting
Temperature and amount of hot water
Problem
Possible solutions
It takes a long time for hot water to
reach the fixtures.
The time it takes to deliver hot water from the water heater to your fixtures
depends on the length of piping between the two. The longer the distance or
the bigger the pipes, the longer it will take to get hot water.
The water is not hot enough
If a tempering valve is installed, is it set too low or malfunctioning?
Are the cold water and hot water lines cross connected?
Is the gas supply valve fully open?
Is the gas line sized properly?
Is the gas supply pressure enough?
Is the set temperature set too low?
Is the combustible air inlet or exhaust outlet blocked?
Is the gas inlet filter in the water heater blocked? Call a service technician to
remove blockage.
Reset power to the water heater to remove a previously set controller
temperature setting
The water is too hot
Is the temperature on the controller with priority set too high?
The hot water is not available when a
fixture is opened.
Does the water heater have a 240V 50Hz power supply available?
If you are using the remote controller, is the power button turned on?
Is the gas supply valve fully open?
Is the water supply valve fully open?
Is the filter on cold water inlet clean?
Is the hot water fixture sufficiently open to draw at least 3.0l/min through the
water heater?
Is the water heater frozen?
Is there gas available to the water heater and (if applicable) does the gas
storage tank have enough gas in it?
The hot water gets cold and stays cold
Is the flow rate enough to keep the water heater running?
Is the gas supply valve fully open?
Is the filter on the cold water inlet clean?
Are the fixtures clean of debris and obstructions?
Is the gas inlet filter in the water heater blocked? Call a service technician to
remove blockage.
Fluctuation in hot water temperature.
Is the filter on the cold water inlet clean?
Is the gas line sized properly?
Is the supply gas pressure enough?
Are the cold water and hot water lines cross connected?
Is the gas inlet filter in the water heater blocked? Call a service technician to
remove blockage.
Water heater
Problem
Possible solutions
Burner does not ignite when water
goes through the water heater.
Is the flow rate over 3.0l/min?
Is there a 240V 50Hz power supply available to the water heater?
Are the cold water and hot water lines cross connected or reversed?
If a remote controller is installed press the "On/Off" button.
The fan motor is still spinning after
operation has stopped.
This is normal. After operation has stopped, the fan motor keeps running for
15 – 75 seconds in order to re-ignite quickly, as well as push all exhaust gas
out of the flue.
White vapour clouds are coming from
the hot air outlet of the water heater
It is normal to see water vapour clouds or steam coming from the hot air outlet
of the water heater especially during cold and wet days.
Remote controller (optional)
Problem
Possible solutions
Remote controller does not display
anything when the power button is
turned on.
Press the ON/OFF button.
If the lamp does not light:
Make sure the water heater has power supply.
Make sure the connection to the water heater is correct.
An ERROR code is displayed
Check the error code on the PCB (see page 19 for details).
Remote controller can not change
the set temperature.
Is priority lamp lit? If it is not, press the priority button after closing all hot
water taps.
