6.4.1 FAULT TRACING
To carry out fault tracing on electrical equipment, a multi-meter, test lamp and wiring
diagram are required. Fault tracing must be done with the power disconnected
unless checks cannot be performed without power to the motor. If a fault is detected,
be sure to keep all personnel clear of the pump when the power is turned on. A
qualified electrician must perform all electrical work. Obey all local codes and
regulations and follow recommended safety procedures.
The following Checklist is designed to aid in identifying possible faults, assuming the
pump has been in operation and functioned previously.
All activities related to the electrical installation, maintenance and operation and
service of the motor module must be in accordance with the

If the stator temperature is too high, check that the pump motor is completely
submerged or that the water supply to the water jacket is turned on during operation
and that the impeller rotates freely.
In case of a moisture sensor fault, check the condition of the oil and check for water
in the motor housing and oil sump. Make sure the overload protection is reset.
