SAVE A SERVICE CALL
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 the 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) near the water heater and ensure
they are turned on.
Note: Check the electricity supply to which
the water heater is connected. If on an Off-
Peak or time controlled electricity supply,
remember heating hours are restricted (refer
to “Off-Peak electricity supply” on page 7).
Check the fuse marked “HOT WATER” or “WATER HEATER” at the
switchboard.
Twin element water heaters
A twin element non-simultaneous model must have power available to the top
heating unit circuit at all times for the water heater to operate as designed.
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. Have your plumber
fit a flow control valve to each shower outlet to reduce water usage.
Temperature pressure relief valve running
Is the relief valve discharging too much water?
Refer to “Temperature Pressure Relief Valve Running” on page 18.
Thermostat setting
Ensure the thermostat setting is appropriate. Have your electrician check and
adjust the thermostat upwards to gain additional hot water capacity.
Refer to “Temperature Adjustment” on page 6.
Warning: Hotter water increases the risk of scald injury.
Water heater size
Do you have the correct size water heater for your requirements? The sizing
guide in the Rheem sales literature and on the Rheem website
(www.rheem.com.au) suggests average sizes that may be needed.
