ITEMS NOT REQUIRING MAINTENANCE
Items that should not require maintenance:
1. Thermostats - the thermostats for your JFT machine are factory set so that your machine will operate in accordance with
accepted regulatory parameters. Upon initial installation, your Jackson representative may adjust the the thermostats if required
but otherwise they should never need to be corrected again. If you find yourself in a situation where you have to adjust the ther-
mostat to maintain the same temperatures, then you most likely have a problem somewhere else. Scale build-up in the tub and
on the heaters can affect the operation of the machine as can a variety of other factors. Thermostats, once they fail, cannot be
repaired and should be replaced.
2. Gear drive - the drive motor is connected to a gear drive that is oil filled. Jackson does not recommend draining the gear
drive for any reason. If the gear drive fails, then it should be replaced, not repaired. If for any reason the oil is drained from the
gear drive the component should be replaced.
Items of note:
1. The final rinse heater is a third-party self-contained unit and should come with its own instruction manual. Refer to that man-
ual for any information regarding troubleshooting or maintenance.
2. The Motor Fault Light on the main control panel is a catch-all warning for all motors associated with this machine. If the Motor
Fault Light illuminates, the machine must be shut down completely and service personnel contacted. A motor fault can be for
any number of reasons and could apply to any one or more of the motors on the machine. Do not operate the dishmachine if
the Motor Fault Light is illuminated.
