Steamtec II Basic steam generator will display the operation states and common malfunctions by
flashing of the main operation LED (pilot lamp) on the bottom housing of the unit (see page 12).
The pilot lamp is off if the generator is off. During active heating the pilot lamp will illuminate
continuosly.

•
flashing once
- waiting for descaling cycle
•

Troubleshooting guide
Fault
: Overheating limiter fuse releases repeatedly or the Pilot Lamp flashes 4 times (water
filling error).
Remedy
: Check the correct position of the limiter fuse. Check the water level probe and clean if
necessary. If the fuse and the level probe are in proper condition you may need to calibrate the
water conductivity measurement. Proceed as follows:
1. Switch off the generator
2. Set the jumpers in the JP1 group to positions „H“ and „M“ (make sure to remember the previ-
ous jumper positions, use the jumper from the JP2 group)
3. Connect the power supply to the generator. The water in the tank will be drained and filled
again. This may take several minutes.
4. Wait until the Status LED on the board flashes 4 times - now the water conductivity level and
the correct water level will be stored.
5. Disconnect the power supply.
6. Remove the jumpers in the JP1 group from “H” and “M” positions and set them to the origi-
nal position.
7. Connect the power supply. The steam generator is now ready for operation.
Fault
: Draining error (pilot lamp flashes 5 times)
Remedy
: Check the drain, make sure it is not blocked by scale and other deposits. If the drain is
clean and motorized ball valve does not appear to function please contact your EOS dealer for
assistance. The ball valve or the actuator may be faulty.
Fault
: Water filling fault (pilot lamp flashes 4 times)
Remedy
: Check the water supply line, make sure there is sufficient water pressure. If the water
supply if correct and you cannot hear the input valve to open and fill the tank please contact
your EOS dealer for assistance.
