Causes

Check power supply

Call an expert to check the pump unit

Check all filters/check valve for foreign matters

Ensure all taps are turned on

Repeat priming procedure (refer to page 8 for flooded suction or

page 9 for lift suction) to remove any air from the system

Check the tightness of the whole pipe up until the pump and

tighten it

Ensure power supply is not running on an extended cable

exceeding 10m. Check voltage on terminals of the motor. It should

be within ± 10 % of 230V (this should be carried out only by

qualified personnel)

Relocate pump to a cooler, better ventilated environment

Decrease pipe length and increase pipe size (diameter)

Decrease head on pump

Ensure pump is fastened to a solid surface by two mounting

screws

Get pump serviced

Check pump is primed and water supply is sufficient

Replace controller
