Water Flowing from Relief Valve

• The incoming water pressure may be too high due to a pressure limiting valve failure, or, due to a pressure limiting valve not having been fitted at all.
• Foreign matter caught under valve seat. Relief valves usually have a small lever, or a knob to turn in order to open the valve. Gently open to valve to give it a flush to remove foreign matter. If this does not work, call us for assistance.
• A common indication of a relief valve failure is that it may discharge at a lower temperature than it is designed to. A Temperature and Pressure Relief valve (TPR) is usually designed to open at 99 degrees, as well as opening at a specific pressure setting. The pressure rating is usually found on the valve label.

Low Hot Water Temperature

• Element or thermostat fault. The element may not be drawing enough power or the thermostat setting may need adjusting. Do not attempt repairs. Call 66844131 for assistance.
• Faulty Tempering Valve. A tempering valve is designed to deliver hot water at a safe temperature. Water cannot be stored below 60 degrees, but should not be delivered to bathrooms above 50 degrees. A tempering valve mixes hot and cold water to ensure water is delivered at a safe temperature. In the event of a tempering Valve (TMV) failure, it may deliver water at a lower temperature than 50 degrees. If there is hot water in the tank, but only luke warm water coming out of the tap, them the TMV may need replacing.

No Hot Water

• Check to see if the circuit breaker has tripped out. This may indicate a fault in an electrical component. Call 66844131 for assistance.
• Faulty Off-Peak relay. If your water heater is connected to Off-Peak or Controlled Load tariff then there may be a fault with the relay. This must be rectified by Essential Energy. Call 13 20 80 for assistance.

Pilot Flame Outage

• Insufficient gas supply. Check that there is gas in the bottle. You can tap the side of the gas bottle, or check that other gas appliances are working.
• Blockage in the pilot jet. This will require a service call.
• Lack of ignition. can be caused by a faulty sparker or some debris shorting out the sparker probe.

• Faulty SIT valve. This controls the temperature of the water by switching the main burner on and off. It is rare for a fault to occur. Make sure the dial on the SIT valve is turned up to the desired temperature.

Heat Pump Not Running

• Check the circuit breaker in the electrical switchboard to make sure it is turned on. If it is on, and power is available to the heat pump then you need to call us to attend.

Heat Pump is Running but there is only a small amount of Hot Water

• In the case of a Saxon Heat Pump, this may only require the tank to be topped up via the filler valve. Please check your manual for the correct procedure.

Heat Pump is Running but there is no Hot Water

• This will certainly require our attendance

No Hot Water Flow

• This is usually caused by a blocked inlet strainer either on the cold water inlet to the system, or on the tempering valve.

No Solar Gain

• No solar gain is when the system only works on booster. This issue can be caused by a loss of heat exchange fluid in a frost protected model or an incorrectly installed system.

Excessive discharge from a relief valve

• Can be caused by a failed pressure limiting valve or a failed relief valve. It is also possible that there is some foreign matter caught under tha valve seat. Gently lifting the lever on the relief valve a few times may resolve this. Be sure to not get burnt by any hot water that may discharge.

No Solar Gain

• Can be caused by a failed pump or controller.

Water is warm, not hot

• Can be caused by a failed tempering valve

Gas Leak

• Sometimes there is a noticeable smell of gas when the gas bottle is almost empty. If you smell gas around the water heater, but only after it has been running, then check the gas bottle to see if it is nearly empty. If so, then the smell may be coming from the combusted gas. If the smell is there continually then there may be a gas leak. In this situation it may be best to turn off the gas bottle and call us for assistance.

No Hot Water

• Continuous flow water heaters can have some complex components and it is not advised to attempt any repairs. If the water heater has a lead that is plugged in to a power point, you can check to see if there is power by plugging in an appliance that you know is working.
