Description of the message Reasons for fault
Lower alarm limit for pressure Leakage; supply pressure too low;
underrun pressurisation incorrectly set
Solenoid valve does not close / is defective;
overrun pSV set too low; pressurisation system
defective
IWZ does not supply any signal Supply flow too low; IWZ not connected
after replenishment request
During the specified Solenoid valve does not open; water supply
replenishment quantity the insufficient; setting incorrect
pressure has not increased by at
least 0.1 bar
During the specified Solenoid valve does not open; water supply
replenishment time the insufficient; setting incorrect
pressure has not increased by at

Fault removal
Repair leakage; increase
supply pressure; set
pressurisation correctly
Replace solenoid valve;
correct pSV setting; e.g.
correct MAG primary
pressure
Connect IWZ; increase
supply pressure
Increase supply quantity; if
necessary, increase setting;
check solenoid valve
switching process
Increase supply quantity; if
necessary, increase setting;
check solenoid valve
