Check tightness of the pressure sensor
system.
Can be acknowledged. Inform customer
service. Error appears after a further 1000
operating cycles.

Check the system design, inform the cus-
tomer service department if necessary.
no network/credits, no connection to the
modem, equipment fault
If it occurs frequently, check the design
and performance of the pump(s).
Establish the specified ambient conditions
for the control unit, see "Technical data",
page 28
Remedial measure
Disconnect the system from the mains
power supply, disable the battery, check
the cable for correct connection and con-
tinuity; test the function of the motor,
replace if necessary
Disconnect the system from the mains,
disable the battery; check the cable for
