TROUBLESHOOTING
Issue
Water heater is not heating
at all (water is flowing but
the unit is not heating - the
outgoing water temperature
is the same as the cold
water supply) - the digital
display does NOT light up.
Water heater is heating,
but the water temperature
is not hot enough.
Leakage in the joint of inlet
and outlet pipe.
The water pressure is less
and less.
Water temperature is
unstable.
16
Possible Reason
No power or incorrect
wiring.
The screen is damaged,
or the screen connection
is poor.
User temperature
setting too low.
Flow rate is too high.
Voltage less than 240
volts.
Mixing too much cold
water.
Poor connection of inlet
and outlet pipe.
The rubber washer is
damaged.
The inlet filter or shower is
blocked by water impurities.
The voltage or water
pressure is unstable.
Solution
Make sure the breakers at main
electrical panel are ON. You may have
a faulty breaker or unit may be wired
incorrectly.
Replace the screen or reconnect the
wire.
Turn up the temperature setting on
the unit.
Depending on your incoming water
temperature and the power output of
your model, your water flow rate may
exceed the physical heating capacity
of your water heater. Turn down the
water flow.
The set voltage of the water heater is
240v. When the voltage used is lower
than 240v, the water heater will
generate less heating power. It would
require a larger power model. (when
the voltage cannot be changed).
You do not need to mix as much cold
water with your tankless water heater
compared to when you use a
conventional water heater. You may
also have an anti-scald feature on
your faucet that is mixing cold water.
These types of faucets can usually be
adjusted to reduce the amount of cold
water mixed.
Reconnect the pipe.
Replace the washer
Remove the inlet pipe, clean the
inlet filter/shower.
The voltage water pressure is
back to normal.
