E01 Internal fault
Overheated water into the outlet tank due to:
- HE1 probe incorrect positioning
E11 the HE1 sheath, place it in the right position;
- HE1 sensor/s out of tune
compliance with "Sensor Test Table"), replace it.
HE1 functional relay stuck due to:
E12 - faulty component
terminals on the PCB, replace the PCB.
High temperature into the outlet tank due to:
- lack of water
- HE1 probe incorrect positioning
E15
the HE1 sheath, place it in the right position;
- HE1 sensor/s out of tune
compliance with "Sensor Test Table"), replace it.
Overheated water into the inlet tank due to:
- HE2 probe incorrect positioning
E21 the HE2 sheath, place it in the right position;
- HE2 sensor/s out of tune
compliance with "Sensor Test Table"), replace it.
HE2 functional relay stuck due to:
E22 - faulty component
terminals on the PCB, replace the PCB.
High temperature into the inlet tank due to:
- lack of water
- HE2 probe incorrect positioning
E25
the HE2 sheath, place it in the right position;
- HE2 sensor/s out of tune
compliance with "Sensor Test Table"), replace it.
HE1 probe short/open circuit due to:
- bad placed or damaged wiring/faulty component
E10
disconnected or faulty (sensor/s values not in compliance with "Sensor
Test Table"), connect/replace it.
High difference of temperature measured by higher and lower sensors into
the outlet tank due to:
- HE1 probe incorrect positioning
E13
the HE1 sheath, place it in the right position;
- HE1 sensor/s out of tune
compliance with "Sensor Test Table"), replace it.
Low heating rate concerning the outlet tank due to:
E14 - incorrect appliance horizontal installation
