Failure diagnostic for use by professionals
The maintenance or repair work must be done exclusively by a professional.
TYPE OF FAILURE
POSSIBLE CAUSE
DIAGNOSTIC AND REMEDY
✔ No hot water
This water heater has a protection
system against dry heating: if the
water heater is not full of water, this
protection system is activated and
disables power supply to the heating
element.
Check if the water heater is full of
water by opening a hot water tap.
✔ No heating
✔ No hot water
No power supply to the water hea-
ter: day/night contact out of order…
Switch to forced operation and check if
there is any power on the power sup-
ply terminal of the electronic thermo-
stat.
Heating element or its wiring out of
order.
Check if there is any power on the
connector of the heating element, bet-
ween blue and red wires.
Circuit of the impressed current
anode (ICA) is open: its wires are
wrongly connected or out of order.
Bad position of the water heater (HM)
Heat sensor missing or wrongly
connected.
Visually check the connection of the
impressed current anode wires.
Check the position of the water heater
and place it in the right position.
Replace the sensor.
Check the presence and the right
connection of the sensor.
✔ Water not warm enough
Thermostat setting too low.
Turn the potentiometer (refer to the
connection label inside the cover).
Power supply time of the water hea-
ter insufficient: day/night contact
out of order.
Check the good working order of the
day/night contact.
Heating element or its wiring partial-
ly out of order.
Check the 3 resistances of the heating ele-
ment on the connector of the element
bundle and the condition of the wire
bundle.
✔ Pilot light always off
Short-circuit on ICA wiring: no ICA
protection.
Pilot light always off: contact the BIP
Service.
First heating operation
At the first start-up or after being switched
off for a long period (secondary residence)
a few minutes are needed before the light
goes on.
✔ In the case of an electricity power
supply for peak hours/off-peak
hours: pilot light off during peak
hours
Storage battery out of order
Note: the storage battery is recycla-
ble and must not be thrown away.
Pilot light off when the water heater
receives no power supply: replace the
storage battery.
✔ Other failures
Contact your import sailer for any
other failure.
Refer to the last page of the manual
for details.
