Fault
Cause
Remedy
Pump runs but does
not transport
Air in the pump
see chapter "Preparation" Diag. A and B
and the chapter "Operation"
Suction pipe blocked
Pull out the mains plug and clean the
suction pipe
Pre-filter is dirty
Remove the pre-filter and clean it under
flowing water; rinse out residual dirt, if
any, in the filter intake by opening the
drain.
Pump does not run or
suddenly comes to a
standstill during oper-
ations
Power supply inter-
rupted
Check fuses and electrical connections
Pre-filter is dirty
Pull out the mains plug, let the pump cool
down, clean the suction area, prevent dry
running
Pump stops, all lights
blink
Failure on the suction
side, pressure cannot
build up
Remove the pre filter and clean it under
flowing water, rinse any dirt residues
from the filter intake by opening the dis-
charge opening.
Check connections to the suction side for
leakage, check backflow valve.
Restart the pump by simultaneously
pressing the + / - buttons.
Flow meter is jammed
or missing.
Check installation and correct orienta-
tion. Clean flow meter.
Restart the pump by simultaneously
pressing the + / - buttons.
Pump stops, two pairs
of lights blink, alter-
nating sides.
Failure in the pressure
line, flow too small,
the pump frequently
switches on and off as
a result of reduced
water extraction.
If reduced water extraction is required,
the switching frequency can be reduced
by increasing the overpump time, and
thus the occurrence of failure “Err2” can
be avoided.
Restart the pump by simultaneously
pressing the + / - buttons.
