Troubleshooting

At Best Price Hot Water, we can help with professional hot water repairs and installations.

But if you're having trouble with your hot water system, it's worth checking out our troubleshooting guide below to see if you might be able to fix the problem yourself before calling us out.

 

 

ELECTRIC HOT WATER SYSTEMS

Hot water system playing up? Before you make a service call check the following items.

 

NO HOT WATER

Check that the isolating switch - generally found in the switchboard and often marked "Hot Water', 'HWS' or 'Water Heater' - is in the ON position. Check that the electricity supply to the hot water system is connected. If connected to off-peak heating, hours are restricted. Also check the switchboard fuse.

 

IF TWIN ELEMENT SYSTEM

For a twin element hot water system to operate as designed, it must have power available to the top heating unit circuit at all times.
So make sure the power is connected and on.

 

TPR Valve (Temperature Relief) LEAKING

While it is normal for this valve to discharge a small amount of water while heating, if it does leak more than 10 litres of water a day, there may be another problem. If it is continuously running, try raising or turning the leaver/knob gently on the TPR valve for a few seconds and then releasing it. This may dislodge any foreign matter which may be in the line. If it continues to leak, please contact us for a service call.

 

COLD WATER LEAKING

Is water leaking from the expansion valve (located in the cold water line to the water heater)? It's normal for this valve to discharge 5-10 litres of water a day. As the cold water heats up in the tank, the water expands and is discharged from the cold water expansion valve.
If the expansion valve is leaking more than 10 litres of water a day, give us a call.

 

GAS HOT WATER SYSTEMS

NO HOT WATER - PILOT LIGHT

If you have no hot water at all check to see if the pilot light is igniting and burning. Re-light the pilot light according to the instructions on the inside of the access cover. If the pilot is not lighting or igniting, check that there is gas to the water heater. Check that the isolating valve on the gas line is turned 'ON'. Also check to see if there is gas being supplied to the rest of the house. If there's more than one gas appliance check all to see if they are lighting. If there is no gas, call the gas supply company.


ELECTRONIC IGNITION - Make sure the power chord is plugged into the wall and check the fuse in the metre box.
