It’s common to have a circulation pump airlock after re-filling your spa. An airlock should be addressed immediately because it won’t take much time for the motor to overheat and burn out, even a new one.Without bubbles shooting out from the foot well, there will also be a “flow error” message on the upper control panel and the heater will not turn on.

1. Air bubbles should be shooting out of the
ozone/heater port in the footwell, about 18”. If
not...

2. Remove the air bleeder valves near the filters.
There should be a constant stream of bubbles
from the ozone bleeder valve port. If not...

3. Turn off power at the GFCI

4. Remove the ozone filter from its canister.

5. Put a garden hose over the ozone bleeder port
and force water into the opening. With any
luck, air bubbles will be forced through the
plumbing and come out the footwell of the spa.

6. Turn on the GFCI. The circulation pump
should run, bubbles should shoot out of the
footwell, and the upper control display should
read normally.

7. If not... turn off the power again at the GFCI.

8. Hold the running hose over the ozone port in
the footwell and watch for bubbles to come
through the port by the filter. You may have to
repeat this top and bottom routine up to 3
times to purge all the air from the circulation
pump plumbing.

9. Turn on power at the GFCI to see if the error
message is gone and the bubbles are flowing
again.


10. When the circulation pump is operating normally,
replace the bleeder valves, filters, and
filter covers.
