Davey MaxiFlow SPA POOL PUMP - Manual (Page 9)

Trouble Shooting
This guide is intended as a guide for an experienced service person only.
When making measurement make sure the power is disconnected first.
If the pump runs but there is no water flow or water flow is reduced, the
following condition may apply:
1. The pump is not primed. Re-prime as per instruction in ‘Starting the pump’
2. There are air leaks in the suction piping. Check all piping and eliminate leaks.
Air bubbles in the water flowing back to the pool would indicate a leak in the
suction to the pump allowing air to enter the pipework.
3. A leaking pump shaft seal may also prevent operating. Evidence of this would
be water on the ground under the pump.
4. The pump is not able to get water from the pool. Check that the valves to the
pump are fully open and that the pool water level is up to the spa jets.
5. Blockage in the piping or pump.
If the pump does not operate, the following conditions may apply:
1. The power is not connected. Where a spa controller is used, check to see if
the controller touchpad is illuminated and the pump is connected to the correct
AMP socket. Also check fuses and the main power supply switch
2. Automatic overload is tripped following an overheating period. The pump motor
has an in-built thermal overload which will re-set after the motor has cooled.
Determine the cause of the overload tripping and rectify.
3. Blockage is preventing the pump from rotating.
4. Motor is burnt out - burning smell is evident. Replacement is required.
If you are unable to resolve any installation or operation difficulties with
