Faults Possible cause Remedy
Pump does not start or fails to run Pump chocked up switch off power supply, take-off pump
head, remove obstruction; if motor blo-
cked, overhaul/exchange motor/pump
head
Loose terminals tighten all terminals
Defect fuses check fuses, change defect fuses
Faulty motor call service
Tripped overload relay throttle hydraulic flow rate down to
nominal at discharge side of pump
Incorrectly set trip relay reset thermal overloads to name plate
FLC-value
Thermal overload are influenced by
excessive ambient temperature reposition overload relay or protect by
thermal insulation
Tripped PTC-relay check motor and fan cover for dirt/dust
accumulation and clean if necessary;
check ambient temperature and if
necessary, ensure an ambient tempera-
ture
ⱕ
40 °C by forced ventilation.
Pump runs at reduced
capacity
incorrect rotation check direction of rotation, if necessary
Discharge valve throttled too far slowly open isolating valve
Speed too low correct wrong terminal bridging
(Y in lieu
⌬
)
Air in suction pipe check and correct flange leakages,
eventually vent pipe section
Pump makes noise insufficient inlet pressure raise inlet pressure, ensure minimum
required inlet pressure at suction port,
check and if necessary clean suction-
side isolating valve and strainer
Faulty motor bearings Arrange for pump to be inspected and, if
necessary, to be repaired by Wilo or
other authorized service.
Impeller scratches Test the contact between lantern and
pumphousing. Clean it, if necessary.
Only original Wilo spare parts are to be
used to ensure the fault-free operation of
the pump.
