Troubleshooting
If an error occurs, the steam generator will be switched off. There will be a warning beep
to alarm the user every 2 seconds. The code for the error will be displayed blinking in the
control panel, see the table below.
Please note, only a qualified electrician or maintenance personnel are allowed to make
the service operations and repairs!
If an error occurs in one of the slave units, error message is followed by slave number. For
example: E1 -> S2 -> E1 ->S2... Pressing ON/OFF button disables the slave and rest ot
the generators can operate normally.
Possible errors are:
Code
E1
Problem
Temperature sensor 1
not connected.
E2
Temperature sensor 1
short circuit.
E3
Temperature sensor 2
not connected.
E4
Temperature sensor 2
short circuit.
E5
Temperature fuse defect.
Solution
Check the wire between the sensor and the
control unit.
If there is no problem with the wires and they
are correctly installed, check the sensor.
If no problem can be found, contact the
retailer.
Check the wire between the fuse and the
control unit. Fuse has probably overheated.
The reason for it needs to be discovered
before using the steam generator again. A new
fuse is needed.
If no problem can be found, contact the retailer.
