4. SYSTEM TROUBLESHOOTING
If you suspect for any reason your Oasis Aquatics PLT Series Pool & Spa Pumps are not
performing or running as it should be, here are some handy troubleshooting tips that may assist
you.
If the pump does not operate, one of the following conditions may apply:
•The power is not connected. For 240 volt only
•Check the power point by plugging in a portable appliance to ensure power is available
•Check fuses and the main power supply switch
•Automatic overload is tripped. The pump has an in-built thermal overload, which will re-set
automatically after the motor has cooled following an overheating period. Determine the cause of
the overload tripping and rectify
•Pump needs to be disconnected for 10 secs and reconnected
•Blockage is preventing the pump from rotating
•If plugged into chlorinator, disconnect and reconnect directly to power after 10 secs. If it then
works, please check your chlorinator manual
•Motor is burnt out - burning smell is evident. Replacement is required
•If you are unable toresolve any installation or operation difficulties with your Oasis Aquatics pool
and spa pump, contact the supplier from whom the pump was purchased or your nearest
Authorized Oasis Aquatics pool and spa pump Pool Equipment Service Centre. If any further
assistance is required, contact the Oasis Aquatics Customer Service Centre at the address
indicated in this manual
If the pump runs but there is no water flow or water flow is reduced, the following
condition may apply:
•The filter requires backwashing or it is blocked.
•The pump is not primed. (See Starting the pump).
•There are air leaks in the suction piping. Check all piping and eliminate leaks, also check for a
loose strainer basket lid. Air bubbles in the water flowing back to the pool would indicate a leak in
the suction to the pump allowing air to infiltrate the pipe work.
•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 skimmer box.
•A leaking pump seal may also prevent operating. Evidence of this would be water on the ground
under the pump.
•Blockage in the piping or pump. Remove the hair and lint pot strainer basket and check for any
blockage to the pump impeller entry.
•To check if impeller is rotating, please lodge a flat-head screwdriver in the back motor through
the fan cowl and twist.
Removal of the Pump from Pipe work
To remove the pump, follow these instructions:
1. Switch off the power and remove the plug from the power source.
2. Close the water valves on the pool return and the pump inlet pipe work.
3. Remove the discharge & suction barrel unions taking care not to lose the o-rings.
4. Move the pipe work with the barrel unions attached until the pump can be moved clear.
