Indicator Light not on

1.  If the light does not come on, but water gets hot, check for faulty bulb.

2.  Check reset button; follow steps from previous section.

Brown water

1.  Brown or rusty water indicates a “spent” anode rod. Replace anode rod.

Odor in water

1.  Smells from the water are usually due to an unusual reaction between local water 

and the heater’s anode, check anode rod.  

This usually occurs on non-municipal water supplies.

Water is too hot

1.  Turn the temperature selector dial counter anti-clockwise to lower temperature.

2.  If temperature does not change then replace the thermostat.

No Water flow

1.  Check service valve is open and ensure minimum operation pressure is above 1 

bar.  

Note: This water heater is not suitable for use on gravity fed systems.

Unit Leaking

1.  Check water connection fittings at the top of tank, ensure the connections to the 

water heater are sound and are not the cause of the leak; if they are leaking, tighten 

the connections.

2.  Inspect heating element gasket for cracks or perishing if there are any signs of 

damage replace element and gasket together.  

NOTE: Elements and Gaskets should always be replaced together; do not reuse an 

old gasket.
