It is recommended that the following points
be reviewed before making a service call:
No Hot Water:
Ensure the power supply circuit breaker
has not "tripped". If the water heater is on a
timed tariff such as off-peak, ensure this is
operating correctly.
High Energy Bills or Insufficient Hot
Water:
•
Often the hot water usage of showers,
washing machines and dishwashers
can be under estimated. Review these
appliances to determine if the daily
usage is greater than the capability of
the water heater.
•
If necessary check the shower flow
rates with a bucket, measuring the
amount of water used over a period of
time. If it is not possible to adjust water
usage patterns, an inexpensive flow
control valve can easily be fitted to the
shower outlet.
•
Is the water heater the correct size for
the requirements? Sizing details are
available from your Dux supplier.
•
Is there a leaking hot water pipe or
dripping hot water tap? A small leak
can waste a large quantity of hot water.
Replace faulty tap washers and arrange
for your plumber to rectify any leaking
pipe work.
•
Is the Pressure & Temperature Relief
Valve discharging too much water? See
below.

Considering a Service Call?
Continuous Trickle of Water from
Pressure & Temperature Relief (PTR)
Valve:
This is most likely due to a build up of foreign
matter. In this case, try gently raising the
easing lever on the PTR Valve for a few
seconds, then release gently.
This may dislodge a small particle of foreign
matter and rectify the fault.
Water Discharge from PTR Valve:
It is not unusual for a small quantity of water
to discharge during the heating of water in
the storage tank. The amount of discharge
will depend on hot water usage and the size
of the storage tank.
As a guide, it will discharge about 2% of the
volume of the water heated.
Continuous leakage of water from the PTR
Valve may indicate a problem with the water
heater. Turn off the water heater and contact
Dux After Sales and Service.
If after checking the above points, the
problem has not been identified, please
contact Dux After Sales and Service.
