Filtration Troubleshooting - Frymaster BIELA14-T Series Service Manual

Incorrectly sized or installed filter 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.
