If the error message still appears after the air lock is purged, it may be due to internal debris, which will
reduce the flow of water through the system, causing the error message. You'll need to clean the circulation
pump and flush the temperature sensor assembly.
You'll need:
• Phillips head screwdriver (preferably cordless)
• 12" of straight wire
• 90 degree Screwdriver
• Pliers (Flat Head screwdriver on some models)
• 2 wine corks with a shaved end on each.
• 3mm Allen head wrench
• Crescent wrench
• Clear, plumbing grade Silicone caulk
To start:
• Turn off the power to the spa at the GFCI
• Remove the equipment access door.
1. Loosen the hose clamps with your
pliers and move them away from the
circulation pump one at a time.
If the mounting plate is screwed to the
floor, remove the screws. Grab the
pump with both hands and pull it out of
the equipment area.
2. Using 2 wine corks, (or similar
items), plug the hoses to stop water
flow.
3. Using the Allen Wrench, loosen the
4 screws holding the volute to the
motor.

4. Remove the 4 screws.

5. Separate the motor from the volute. Remove any visible debris.

6. Separate the impeller from the motor. It is held magnetically.

7. Remove any visible debris.

8. Replace the impeller.

9. Remove, clean, and replace the sealing
gasket on the inside of the volute.

10. Re-assemble the motor and volute.
