8.11 Jets Pump Runs and Quits During Jet Mode
This is usually a problem of pump overheating. The pump motor incorporates a thermal cutout
switch that triggers when the motor gets too hot. There is no reset for this condition. When the
motor cools, the thermal switch resets automatically. In some cases, a faulty circuit can also
cause this problem.
Diagnostic Tools: Clamp-on Ammeter, Voltmeter
Suggested Spare Parts: Circuit Board, Jets Pump
Standard Troubleshooting Approach
This applies to 2011-2013 J300 Models not 2014+
Refer to pages 50-53 for testing points.
