The BUB message indicates that the Jet function has been activated. This message will appear when the Jets button has been pressed and will interchange with the current jet speed level (L-1, L-2 or L-3).
The green Jets indicator light will be on and no action is required.
NOTE: The Jet function cannot be activated at the same time as the Filtration system.
The Jet Massage system will stop automatically after 15-30 minutes of operation. Reactivate the jets by pressing the Blower button again. If the jets do not reactivate immediately, this may be due to a possible overheat.
Give the unit time to cool down (at least 15 minutes) and try again!
