- not much goes wrong with pool pumps but, if you have a problem with one, this will help you solve it

Pump will not start

- possible causes and cures

• No power supply to the pump - check the supply

• The pump is not switched on - switch it on

• The circuit breaker has tripped - re-set the breaker

• The pump is set to ‘Auto’ and the timer is preventing the pump from switching on - change the timer to ‘Manual’

• The impeller is clogged with debris - remove the pump, disassemble and clear the impellers

• The start capacitor is defective (pump buzzes but does not turn) - replace the capacitor

• The motor shaft is corroded and preventing the pump from turning - repair or replace as required

The pump does not prime

- possible causes and cures 

• There is no water in the pump strainer basket chamber - fill the chamber with water

• There is an airlock in system - clear the airlock

• The pump lid is not tightened fully - remove lid and re-tighten

• The pump lid O-ring is damaged, allowing air to enter the strainer basket chamber - replace the O-ring
