SAVE A SERVICE CALL
Check the items below before making a service call. You will be charged for attending to any condition or fault,
which is not related to manufacture or failure of a part (refer to
“Terms of the Rheem Warranty”
on page 27).
COLD WATER FROM THE HOT TAP
Close the hot tap, wait 10 seconds and open the hot tap again.
Is the hot tap open enough or is the water flow rate too low?
The burners will not light if the flow rate is less than 3.0 L / min.
The cold water inlet strainer may require cleaning.
Is the isolation valve in the gas line open?
Is there a gas supply to the rest of the house?
Try lighting another gas appliance.
Has the gas line been purged of air after installation?
Refer to your plumber.
WATER IS NOT HOT ENOUGH
Is the seasonal water flow adjustment valve set to an inappropriate setting?
Set to the “Winter” position.
WATER FLOW OR TEMPERATURE FLUCTUATES
More than one tap in use at the same time may cause a decrease in the hot water flow or a fluctuation in hot
water temperature from the taps.
Is more than one tap open, or is an appliance such as a dishwasher or washing machine, in use at the
same time?
Ensure only one tap or appliances is on at the one time.
Is one outlet (especially the shower) using more hot water than you think?
Check the flow of the water from one tap, e.g. the shower. The shower should be adjusted so the hot tap
is fully open. Installing water saving shower heads and tap ware or a flow control valve to each hot water
outlet can reduce water flow and temperature fluctuation.
Do you have the correct size water heater for your requirements?
The sizing guide in the sales literature and on the Rheem website (
www.rheem.com.au
) suggests average
sizes that may be needed.
REDUCED HOT WATER FLOW WHEN HEAT EXCHANGER IS COLD
At a cold start-up, i.e. when the water heater has not operated for some time (which is most often first thing in
the morning), the initial flow of hot water may be reduced for a period of 5-10 seconds while the heat exchanger
warms up.
This is both an energy and water saving feature of this water heater.
Once the heat exchanger
has warmed up the hot water flow will increase and remain at normal flow levels. This feature will only occur
at a cold start-up and not when the heat exchanger is already warm from a recent use of hot water.
NO WATER FROM THE HOT TAP
No flow of water from the hot tap may indicate a restriction in or failure of the cold water supply to the water
heater. Check for water flow at other taps and that the cold water isolation valve
(refer to page
20
)
is fully open.
