Trouble Shooting
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 your QB
Series pump, contact the supplier from whom it was purchased or your nearest
Authorised Davey Pool Equipment Service Centre. If any further assistance is
required, contact the Davey Customer Service Centre at the address indicated in
this manual.
Removal of the Pump from Pipework
Should it be necessary to remove the pump, follow these instructions:
1. Switch off the power and remove the plug from the power source.
NOTE: If the pump is hard wired into a time clock or another automatic
control, the wiring should be removed by a qualified electrician.
2. Close the water valves on the pool return and the pump inlet pipework.
3. Remove the discharge & suction barrel unions taking care not to lose the
o-rings.
4. Move the pipework with the barrel unions attached until the pump can be pulled clear.
NOTE: When making any enquiries about your Davey QB Series be certain
to quote the model number from the nameplate located on motor.
Water Quality
Maintaining balanced water chemistry is important to the life of your spa pool pump.
This pump is designed to be used with Pool & Spa water, balanced in accordance
with Langelier Saturation Index, with a pH level of between 7.2 and 7.8 and is
regularly treated with a chlorine sanitising agent with the level not exceeding 3PPM.
Please consult your local pool shop regularly to have your water tested.
