A4: TEMP. SENSOR
DISCONNECTED
Meaning :
This means that the temperature sensor either fails or does not work
correctly.
In that case :
When this message appears, the tank is drained, the general fault
contact is activated and the unit is then stopped.
Causes and remedies
1.
Check the electrical connections.
The temperature
sensor must be connected to the X04 connector and to
terminals 15 and 16 with the main board. The chassis
ground lug is connected to the card fixing screw.
2. Faulty temperature sensor.
Disconnect the temperature sensor from the X04 connector and with a
multimeter measure the ohmic value of the PT100.
For example: for a T° of 20° C, the resistance is 107.8 ohm. If the value seems to prove that the sensor is
faulty, then replace it. In this case, it is necessary to check and maybe redo the calibration of this sensor.
For this, from the menu "CALIBRATION SENSOR T°C" enter the code 1.1.1., visualize the temperature of the
water, once the steam production is established, adjust the temperature in order to have: 99° C.
3. Electronics.
Replace the level management card or the main board.
Also, check that there is no rising steam or water flow in the electrical compartment.
