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. The power supply must be a Continuous / Time of Use
electricity supply.
Check the fuse marked “HOT WATER” or “WATER HEATER” at the
switchboard.
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 19.
Water heater size
Do you have the correct size water heater for your requirements?
TEMPERATURE PRESSURE RELIEF VALVE RUNNING
Normal Operation
It is normal and desirable that this valve allows a small quantity of water
to escape during the heating cycle. However, if it discharges more than
a bucket full of water in 24 hours, there may be another problem.
Continuous dribble
Try gently raising the easing lever on the relief valve for a few seconds
(refer to
“Temperature Pressure Relief Valve”
on page 15). This may
dislodge a small particle of foreign matter and clear the fault. Release
the lever gently.
Steady flows for long period (often at night)
This may indicate the mains water pressure sometimes rises above the
designed pressure of the water heater. Ask your installing plumber to fit
a pressure limiting valve.
Warning:
Never replace the relief valve with one of a higher
pressure rating.
Heavy flows of hot water until water heater is cold - then stops until
water reheats
The water heater
must
be switched off at the switchboard. Phone your
nearest Solahart Dealer to arrange for an inspection.
EXPANSION CONTROL VALVE RUNNING
If an expansion control valve is fitted in the cold water line to the water heater (refer to the
on page 29) it may discharge a small quantity of water instead of the temperature pressure relief valve
on the water heater. The benefit is that energy is conserved as the discharged water is cooler.
