Filtration Malfunction

The majority of filtration malfunctions arise from operator error. One of the most common errors is placing the filter paper on the bottom of the filter pan rather than over the filter screen.

Inspect the filter paper to ensure that it is correctly sized and placed. Incorrectly sized or installed filter paper will allow particles and sediment to pass through the filter pan and into the pump. When sediment enters the pump, the gears can bind and cause the motor to overheat. If the motor overheats, the thermal overload will trip to protect the motor from further damage. Reset the motor by pressing the red reset button the end of the motor nearest the operator. Sediment cannot enter the pump when the correct filter paper is used properly.

While you are checking the filter paper, verify that the O-rings on the filter pan and connectors are present and in good condition. Missing or worn O-rings will allow the pump to suck air and decrease its efficiency.

A pump seized by debris or hard shortening can usually be freed by manually moving the gears with a screwdriver or other tool.

1. Disconnect power to the filter system.

2. Remove the input plumbing from the pump.

3. Use a screwdriver to manually turn 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 during filtering.

Pan blockage can also occur if shortening remains in the pan and solidifies. The heater strip on the suction tube prevents solidification of residual shortening left in the tube. It will not melt or prevent solidification of shortening in the pan. Remove blockages 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.

The Power Shower may need service for clogged openings, shortening solidified in the tubes, missing clean-out plugs, and missing or worn O-rings. To correct these problems, clean the unit and replace missing or worn plugs and O-rings.
