If the pump motor overheats, a circuit breaker will trip and the motor will not start until the breaker
is reset. If the pump motor does not start, press the white reset button located under the component
box, inside the cabinet.
If the pump starts after resetting the breaker, then something is causing the motor to overheat. A
major cause of overheating is when several frypots are filtered sequentially, thus overheating the
pump and motor. Allow the pump motor to cool at least 30 minutes before resuming operation, and
allow time for the motor to cool between sequential frypot filtering.
Pump overheating can be caused by:
• Solidified shortening in the pan or filter lines,
or
• Attempting to filter unheated oil or shortening.
Cold oil and shortening are more viscous, causing the pump motor to overheat. Always filter with
the oil or shortening at operating temperature [350°F (177°C)].
If the motor runs but the pump does not,
there is a blockage in the pump. Incorrectly
sized or installed paper/pads will allow food
particles and sediment to pass through the
filter pan and into the pump. When sediment
enters the pump, the gears bind, causing the
motor to overload, again tripping the thermal
overload. Solidified shortening in the pump
will also cause it to seize, with the same
problem.
A pump seized by debris or hard shortening
can usually be freed by manually moving the
gears with a screwdriver or other instrument.
Disconnect power to the filter system,
remove the input plumbing from the pump,
and use a screwdriver to manually turn the
gears.
● Turning the pump gears in reverse will
release a hard particle.
● Turning the pump gears forward will push softer objects and solid shortening through the
pump and allow free movement of the gears.
Incorrectly sized or installed paper/pads allows food particles and sediment to pass through and clog
the suction tube on the bottom of the filter pan. Particles large enough to block the suction tube may
indicate that the crumb tray is not being used. Pan blockage can also occur if shortening is left in the
pan and allowed to solidify. Blockage removal can be accomplished by forcing the item out with an
