Presentation
Possible cause
Safety thermostat deactivated
Water heater operational fault
4.3. No hot water
Possible cause
Temperature sensor fault
Heating resistor supply fault
Heating resistor fault
58
Installation
Action to be taken
Check the power supply at the
outlet of the safety thermostat(s)
Check the water heater power
supply at the PCB using a
measuring device (multimeter) to
ensure it is 230 volts.
Check that the cable connecting
the PCB and control unit is
correctly connected
Action to be taken
Check the ohmic value of the
sensor using a measuring device
(multimeter)
Check the supply to the resistor
terminals using a measuring
device (multimeter)
Check the ohmic value of the
sensor using a measuring device
(multimeter)
Resistance of the regulation sensor according to the temperature
Sensor temperature (°C)
Use Maintenance Warranty
Solution
Reactivate the thermostat safety
device. If this fault is still present,
contact an installer and the After-
Sales service
If the power supply is correct,
contact an electrician to have the
PCB replaced
Reconnect the connecting cable
correctly
Solution
If the ohmic value is irregular,
contact an installer to have the
sensor replaced
If there is no power supply,
contact an installer to have the
power board replaced
If the ohmic value is irregular,
contact an installer to have the
resistor replaced
