Have faults remedied by qualified personnel only! Observe the
safety instructions in chapter 10 "Maintenance" on page 110.
• If the malfunction cannot be rectified, consult a specialist techni-
cian or the nearest customer service centre or representative
office.
For faults, their causes and remedies, see the "Fault/warning mes-
sage" flow diagram in chapter 11.3 "Acknowledge fault" on page 120
and the following tables. The first column of the table lists the code
numbers displayed in the event of a fault.
NOTE:
If the cause of the fault no longer exists, some faults resolve them-
selves automatically.
The following types of errors can occur with differing priorities
(1 = lowest priority; 6 = highest priority):
Error type Description
A
A fault exists; the pump stops immediately.
The fault must be acknowledged at the pump.
B
A fault exists; the pump stops immediately.
The counter is increased and a timer counts
down. After the 6th fault, this becomes a def-
inite fault and has to be acknowledged at the
pump.
C
A fault exists; the pump stops immediately. If
the error exists for more than 5 min, the coun-
ter is increased. After the 6th fault, this
becomes a definite fault and has to be
acknowledged at the pump. Otherwise the
pump restarts automatically.
D
Like error type A, but error type A has a higher
priority than error type D.
E
Emergency operation: warning with emer-
gency operation speed and activated SSM
F
Warning – pump continues to turn
Cause
Fuses defective
Stop valve on the pressure side throt-
tled
Air in the suction line
Cavitation due to insufficient supply
pressure
Motor has bearing damage
Remedy
Check all cable connections
Check fuses; replace faulty fuses
Slowly open the stop valve
Repair leaks on flanges, vent the pump,
change the mechanical shaft seal in case
of visible leakage
Increase supply pressure, observe mini-
mum pressure at the suction port, check
slide valve and filter on the suction side
and clean if need be
Have the pump checked by Wilo cus-
tomer service or a specialised service
centre and repaired if necessary
