Causes Consequences Troubleshooting
Error 03
Water temperature
sensor defective or
out of range
Not possible to read
the water
temperature: no
heating.
Check
the connection (A1 mark) of the
water
temperature
sensor (thermowell). Check
the
sensor
resistance (see table below).
If
necessary, replace the sensor.
Error 07
No water in the tank
or open ACI link
No heating
Fill
the tank with water.
Check
the wiring connection (AC mark),
the
conductivity
of the water.
Error 09
Water temperature
too high (T>80°C)
Risk of triggering
mechanical safety:
no heating
Check
if the actual water temperature at
the
water
outlet is high (T>80°C).
Check
the connection (A1 mark) and
the
position
of the water temperature
sensor
(thermowell),
it must be on the stopper.
Check
that the electrical backup is not
running
continuously
. Reset the mechanical safety
if
necessary
.
