Replacing The Filter Motor, Filter Pump And Related Components - Frymaster MARINE E4 FPRE 17 kW Installation, Operation, Service, And Parts Manual

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 will also allow 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 auger or drain snake. Compressed air or other pressurized gases should not be used to
force out the blockage.
