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 14.

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 15.

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 15.

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.

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.

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 ten seconds then switch on again. If the water heater fails to light, phone Rheem

Service or their nearest Accredited Service Agent to arrange for an inspection.
