Fault Blow-Down
Unit shuts off auto-
matically
• Blow-down pump has not been electrically
activated
- Cable connections are faulty
- The relay on the main PCB is not operating
•
•
Check or replace cable connec-
tions
Measure voltage at the PCB
terminals against N or replace PCB
• Defective blow-down pump • Replace blow-down pump.
• Solenoid valve does not close properly. Water
level in the cylinder sinks very slowly even
though blow-down pump flushes out water.
• Check solenoid valve.
• Blow-down pump operates, but no water is
pumped out, i.e. the cylinder drain is blocked.
• Thouroughly clean steam cylinder
and base to prevent short-term
blockage from reoccurring
• Blow-down pump is blocked up with mineral
deposits.
• Check blow-down pump, drain as-
sembly and cylinder for mineral
deposits and clean.

Fault Max.-Level
Unit shuts off auto-
matically.
• If the water level “max. level” is reached, the
pump switches on and drains the cylinder
until the water level lowers to “operation.” If
the “max.-level” is reached five times, “max.-
level” is displayed.
• Air pressure in the duct is too high. Duct air
pressure enters the cylinder via the steam
hose. Water is forced into the drain.
• Reduce air pressure or detach vent
pipes from the unit and place higher
