7. Fault finding
(Make sure to disconnect the power before attempting to diagnose any fault.)
Fault
Cause
1. Pump does not start
1. Check if electrical power source, fuse or circuit
breaker failed.
2. Check if pump is locked up by sand, rust or any
foreign objects.
3. Check if the motor is defective due to overload
or other causes.
2. Pump runs at reduced capacity or no discharge
water
1. If it is a three phase motor, please check if the
direction of rotation is correct.
2. Check if the inlet source is sufficient, the
suction lift is not too great and the temperature
is within the normal range.
3. Check if there is any leakage in suction pipe,
check valve works normal and mechanical seal
is not defective etc.
3. Pump stops during operation
1. Motor overheat due to excessive suction lift or
too high liquid temperature.
2. Control circuit has cut out (pressure switch or
level controller).
