Troubleshooting
Pump not pumping properly / water flow reduced
Ÿ
Pump is not primed and wet end full of air - attempt to reprime pump and/or bleed air
from pump by loosening barrel unions.
Ÿ
Pump is starving for water - check the valves to the pump are open fully, check water
level - top up if necessary, check spa filter cartridges and clean if required.
Ÿ
There are air leaks in the suction line - check all pipe work and tighten mac unions to
eliminate leaks.
Ÿ
A leaking mechanical seal may also cause problems with the pump bearings and make it
difficult for the pump shaft to rotate - water or chemical calcification will be evident
underneath the pump if the seal has been leaking. Service pump in this case.
Ÿ
Impeller is worn out - service pump and replace impeller
Pump does not start
Ÿ
The power cord is not connected - check power cable. Where the pump is connected to a
spa controller check the pump is connected to the correct pump socket, check dip
switches are set correctly, and check controller touch pad to confirm pump is active.
Ÿ
Low voltage - check there is proper voltage applied to the pump and avoid using
extension cables.
Ÿ
Blockage in pipe work or pump wet end in preventing the pump from rotating - inspect
for foreign debris and remove where required.
Ÿ
Motor has overheated and thermal cut-out has activated - the pump motor has built in
thermal protection which activates when the motor becomes too hot and automatically
resets after the motor has cooled. Determine the cause of overheating and rectify - check
motor has adequate ventilation, fan is not blocked and can spin freely.
Ÿ
Motor has seized bearings due to a leaking mechanical seal over an extended period of
time - get bearing and seal service if possible, if not replace pump.
