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 power outlet adjacent to the water heater and ensure the water
heater is plugged in and the outlet 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 8.
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 8.
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.
Pressure relief valve running
Is the relief valve discharging too much water? (Refer to
“Pressure Relief Valve Running”
on page 9).
Thermostat setting
Ensure the thermostat setting is appropriate. You may choose to have your installer adjust the thermostat
upwards to gain additional hot water capacity.
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 Raypak sales
literature and on the Rheem website
(www.rheem.com.au) suggests average sizes that may be needed.
WATER HEATER NOT OPERATING
The ignition system may have „locked out‟. To reset the water heater, switch the electrical supply off at the isolating
switch, wait five (5) minutes then switch on again. If the water heater fails to light, phone your nearest Rheem
Service Department or Accredited Service Agent to arrange for an inspection.
DIAGNOSTIC FEATURES OF ELIWELL ELECTRONIC THERMOSTAT
