Faults, causes and remedies

WILO SE 2020-12

FAULT

CAUSE

REMEDIES

Slip between stator and rotor

Have it repaired at the factory

Unbalanced voltages on the three
phases

Check the power supply

Instantaneous overload/foreign body
in the pump

Disassemble the pump

Sudden loss of speed

Single-phase operation

Check power supply and fuses

Voltage drop

Check the power supply

Magnetic noise, sudden whistle

Short-circuits in the motor winding

Factory repairs

Slip between stator and rotor

Factory repairs

Loose bolts

Check and tighten

Magnetic noise, sudden whistle

Fan cover screws, loose joint covers

Check and tighten

Creep between fan and motor cover,
between coupling and coupling cover,
etc.

Ensure correct distance and reassemble

Mechanical noise

Foreign bodies in the motor or pump

Dismantle and remove

Non-aligned joint

Realign

Bearings poorly lubricated or worn/
broken

Lubricate with grease or replace

Damaged bearings

Replace

Overheating of pump/motor bear-
ings

Insufficient lubrication

Re-grease

Misalignment between pump and mo-
tor

Realign

Pump cavitation

Review the sizing of the system

Abnormal vibrations

Water with high air content

Check that there are no leakages in the suction line.
Check the distance between the suction units. If more
than one pump is installed, install anti-vortex plates

Bearing wear, pump/motor shaft

Replace

Wear on pump/motor coupling rubber
plugs

Replace

Misalignment between pump and mo-
tor

Realign

The motor does not stop after
pressing the STOP button

It's normal if the pressure in the sys-
tem is not restored

Deactivate automatic mode with the "AUTOMATIC OFF"
switch and then press the STOP button

Control unit failure

Open (pos. 0 ) the main switch disconnector of the
switchgear

MAIN DIESEL PUMP

FAULT

CAUSE

REMEDIES

The motor does not start or tries to
start and then stops

Batteries discharged

Check the batteries and chargers. Charge the batteries
and replace them if necessary

Fuel shortage

If not indicated by the light on the switchgear, check the
tank and the alarm float. Replace. Fill the tank.

Presence of air in the fuel circuit

Unplug the circuit by venting the injectors and the fuel
filter

Clogged diesel filter

Replace

Clogged air filter

Replace

Fuel circuit failure:

injector blocked

injection pump failure
