FREEING A SIEZED PUMP
A pump seized by debris or hard shortening can usually be freed by manually moving the gears with
a screwdriver or other instrument.
1. Disconnect power to the filter system.
2. Remove the input plumbing from the pump.
3. Use a screwdriver to manually turn the gears.
• Turning the pump gears backward 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 will also allow food particles and sediment to pass through and
clog the suction tube on the bottom of the filter carriage. 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. The heater strip
on the suction tube is designed to prevent solidification of residual shortening left in the tube. It will
not melt or prevent solidification of shortening in the pan.
A blockage can be removed by forcing the item out with a stiff wire or drain snake. Compressed air
or other pressurized gases should not be used to force out the blockage.
Possible problems with the Power Shower include clogged openings, solidified shortening or debris
in the tubes, missing clean-out plugs, and missing or worn O-rings. Cleaning the unit and replacing
missing plugs and missing or worn O-rings will correct these problems.
The electronics of the filter system are simple and straightforward. Micro-switches, attached to
handles for each vat and wired in parallel, provide the 24 VAC required to energize the pump relay
coil when the oil return handles are moved to the ON position. The energized pump relay supplies
the power to the pump motor.
The suction tube heater and flexible hose heater are wired directly into the 24 VAC source. They
remain energized as long as the unit is plugged into an outlet.
