SF  or  SAFETY FAULT  Message

There is a "Safety Fault" (SF) condition on a spa with a pump suction blockage switch.  If the spa does NOT have a pump suction blockage switch, there may be a problem with J82 on the System Board.

On a spa with a pump suction blockage switch, the vacuum switch has closed indicating that there has been a suction problem or an entrapment avoided.  Press any button to reset after the problem has been corrected, or Continue for a Detailed Test Procedure.  Also Continue if the spa with the "SF" Message does NOT have a pump suction blockage switch.
