TROUBLESHOOTING

1.NO SPRAY

1.1 Pump assembly

Be sure the spray switch is ON

Check impella magnet. Impella should spin freely. If it does not, remove and clean both impella and support pin.

NOTE: Check that the Impella assembly is in upright position, fins facing upward.

Sugar and solids can crystallize and cause impella to bind. Do not allow these materials to dry on parts.

Bearing in impella could be worn causing impella to scrap the base of the bowl. Replace the impella assembly.

NOTE: Switch must be OFF when inserting the impella into the bowl to insure magnetic coupling.

Long pieces of pulp may plug impella and bind the impella blades. Juices with excessive pulp must be strained in order to spray. If it is desired to retain pulp, use the Jet-Spray Circulator #S6737 in place of the pump.

With the JS/JT/JWT series, assure that the pump housing is locked into place. If either of the tabs located on the bottom perimeter of the pump housing assembly are broken, the pump will not spray properly. With the TJ/EJ/J15 series, the pump cover should be locked under all three bowl lugs. If any of these are broken the pump will not spray properly and will vibrate and be noisy. Replace the bowl assembly or use the Jet-Spray Circulator #S6737.

1.2 Spray Drive Motor

To check the spray power source, remove front splash panel or side panels, depending on the model, by removing the screws. This will expose the spray drive assembly. The drive assembly must spin freely. If shaft or magnet rubs or binds, adjust or replace it.

The spray drive motor must run in a counterclockwise direction.

If the motor is stopped or not up to speed it will affect circulation and temperature of the drink. Replace spray switch or spray drive motor.
