Check the items below before making a service call. You will be charged for attending to any condition or
fault that is not related to manufacture or failure of a part.
NOT ENOUGH HOT WATER (OR NO HOT WATER)
Is the electricity switched on?
Inspect the isolating switch marked "HOT WATER" or "WATER HEATER" at the switchboard and the
isolating switch (if one is installed) at the water heater and ensure they are turned on.
Check the fuse marked "HOT WATER" or "WATER HEATER" at the switchboard.
Is a timer installed?
If a timer has been installed, ensure sufficient time has been allowed to reheat the storage tank.
Are you using more hot water than you think?
Is one outlet (especially the shower) using more hot water than you think?
Very often it is not realised the amount of hot water used, particularly when showering. Carefully review
the family‟s hot water usage. As you have installed an energy saving appliance, energy saving should
also be practised in the home.
Adjust your water usage pattern to take advantage of maximum
energy gains. Have your plumber install a flow control valve to
each shower outlet to reduce water usage.
Heat pump fault
Has the heat pump developed a fault and the red LED is flashing?
The heat pump will not operate and the water heater will switch to
backup heating mode using the booster heating unit.
Refer to
"Heat Pump Is Not Operating"
Temperature pressure relief valve running
Is the relief valve discharging too much water?
Refer to
"Temperature Pressure Relief Valve Running"
Water heater size
Do you have the correct size water heater for your requirements?
The sizing guide in the sales literature and on the Rheem website
average sizes that may be needed.
WATER NOT HOT ENOUGH
You may find that due to heavy hot water usage the water temperature may be lower than normally
expected, due to insufficient heating time being allowed. You will need to carefully plan your use of the hot
water on such occasions.
A RheemPlus water heater is temperature limited to 50°C at the hot water outlet.
WATER TEMPERATURE TOO HIGH
A RheemPlus water heater is fitted with a temperature limiting valve set to deliver water not exceeding 50°C.
If the water is being delivered at a temperature exceeding 50°C, phone Rheem Service or their nearest
Accredited Service Agent to arrange for an inspection. Care must be taken by all householders when using
hot water until the valve is serviced or replaced.
