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 manufacture or failure of
a part.
NOT ENOUGH HOT WATER (OR NO HOT WATER)
•
Is the electricity switched on?
Inspect the isolating switch adjacent
to the water heater and ensure it is
turned on.
•
Is there a time clock on the power
supply?
Check the settings on the time clock
and ensure they are suitable to enable
heating when it is required.
•
Is the ignition system ‘locked out’?
Reset the water heater. Refer to
“Water Heater Not Operating” on
page 12.
•
Is a code displayed on the electronic thermostat?
Check the LED display on the electronic thermostat. If a code is displayed,
refer to
“Diagnostic Features of Electronic Thermostat” on page 12.
•
Are you using more hot water than you think?
Are outlets (especially the showers) 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 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 13).
•
Thermostat setting
Ensure the thermostat setting is appropriate. You may choose to have your
electrician adjust the thermostats upwards to gain additional hot water
capacity.
Note:
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.
