Troubleshooting
Problem
Probable cause
Solutions
Motor is running, but pump does
not suck in liquid.
Incomplete filling of the pump
with water after commissioning
Fill pump completely with water.
Reduction in the amount of water
sucked in during suction due to
the open side drain
Fill pump; when starting up
again, raise pressure line by 1
m
and hold it until pump begins to
suck in.
Insufficient sealing of the suction
line
Check connections on pump
(suction hose connections, high
pressure hose connection, hose
clamp, suction line, seals with
sealing tape and hemp fibres);
pump only sucks when there is
negative pressure.
Blockage of filter guard or bottom
valve at suction connection
Clean filter guard and bottom
valve on suction connection.
Removal of air not possible due
to closed water drainage connec-
tion
Open water drain connection (tap
or nozzle) when pumping.
No water pumping in specified
waiting time
Fill entire suction line with water
and check again after 7
min.
Suction height too high
Reduce suction height (max.
7
m).
Bottom valve malfunction
Check water level of source; if
possible, extend suction line.
Motor does not run.
No power supply
Check voltage.
Impeller obstructed by fan guard
Pull out plug, unscrew fan guard,
turn impeller on slightly by hand
to check for free movement.
Impeller obstructed
Pull out plug, unscrew fan guard,
slightly turn motor shaft by hand
to drive impeller; if shaft is ob-
structed, have pump checked by
specialist.
Insufficient water transport
Suction height too high (>7
m)
Check suction height.
Filter guard on bottom valve
clogged
Clean filter guard.
Significant drop in water source
level
Immerse bottom valve deeper.
Pump performance impaired by
foreign matter
Clean spire casing, suction line,
and pressure line with pressur-
ised water, or send pump to-
gether with the pre-filter to a spe-
cialist for inspection.
Pump switched off by overheat-
ing protection switch
Motor overload due to friction or
foreign bodies
Clean spire casing with pressur-
ised water, or have the pump
checked by a specialist.
