8.12 Circulation Pump Not Working (JLX, J300 and J200 with circ pump option only)

The circulation pump works as follows:
• 2011+ JLX Models circ pump runs 8 hrs (default)
• 2012-2013 J335/J345/J355/J365/J375 8 hrs (default)
• 2011 J335/J345/J355/J365/J375 8 hrs (default)
• 2011-2013 J315/J325 24 hrs (default)
• 2011-2012 J280/J270/J230 circ pump was an option, 24 hrs (default)
The circulation pump should be running unless "summer logic" is activated. Verify "summer logic" is not acti-
vated before starting. Refer to Section 5.4 (page 14) for details.
The circulation pump is preset to run for a specific filter cycle, two minutes after power up. If the circulation
pump is not running, turn power off to the spa then back on and wait two minutes for the cycle to begin. Or
raise the temperature to initiate a heat call.
Diagnostic Tools: Clamp-on Ammeter, Voltmeter
Suggested Spare Parts: Circuit Board, Circulation Pump
Standard Troubleshooting Approach
Refer to pages 50-53 for testing points.
Is 240 VAC (120 VAC
for J-210, J-315, J-325)
present at pump output?
Test Points 14 and 15.
Yes
Is there current draw (0.5
Amp)? Check with clamp-
on ammeter.
Yes
Current draw is proof
that circulation pump
is working. Read steps
above to make sure
circulation pump should
be on*.
*Note: If circulation pump is running but there is no flow, check for an excessively dirty filter, an air lock, block-
age in the plumbing, debris in the pump, or a broken pump impeller.
