Error description
Description / Remedy
No water supply to steam generator
open Water tap, check solenoid Y1
Gas units wrong polarity of power
supply
Change phase and neutral
Reset gas
press timer key to reset (follow error tree)
PCB is too warm
Cooling not effective
Check air filter, cooling fan and control panel gasket
Check for external heat sources
Unit had done a self test without
water;
Now water is detected and a full self
test must be done.
Cool down unit, make sure B1, B2 and B4 is below 40°C,
Set Self test to „1“ in SE20 and switch unit off and on again.
Run Self test
Energy optimsing system active
230V input missing; If sticker over PCB relays is
reading 42.00.090 the plug with wire link 40.04.180
must be installed on terminal X20
M4 SC pump
pump defective
Thermocouple B1 above 340°C
Check SSR
external EEPROM
Data structure on pcb is older than on the EEPROM
external EEPROM
essential unit data are missing (energy, size, etc)
external EEPROM
Run recovery software
external EEPROM
EEPROM not connected
1, 2, 4, 8
Thermocouple
defective
thermocouple defective.
20.1=B1 , 20.2= B2, 20.4= B4, 20.8= B5
(e.g. 20.12 = B4 + B5)
Temperature B5 rises without
heat demand from PCB, SSR
steam defective
permanent buzzer
Temperature B1 rises by 100°C
without heat demand from PCB,
SSR hot air defective
permanent buzzer
No water flow detected during
Cleanjet
during CleanJet the fan motor does not an increase
in power demand when water hits the fan wheel. -
check water pressure, water supply,
Racks or trolley properly inserted.
Drain valve does not find the
open or closed position
Micro switch drain valve not working properly
Initialise drain valve in bini (dip2),
time ration should be 1: 3 e.g 9:27 sec or 6:18 sec.
test drain valve in bini (dip29), f drain valve not
working change drain valve assembly

2
Thermocouple B5
1 temperature B5 below -5°C (23°F)
2 temperature B5 above 150°C (302°F) (Hysteresis 150-
110° on-off). steam heating switched off, error
message is suppressed for 30 sec.
PCB temperature
temperature above 80°C (176°F)
emergency humidity control
E36 or e37 active for longer than 15 min
core probe
defective
