| C. Blockage in filter pump. | |
| Test: Close the drain valve and | |

Corrective Action
A. Verify that the power cord is fully plugged in. If so, verify that circuit breaker is not tripped.
B. If the motor is too hot to touch for more than a few seconds, the thermal overload switch has probably tripped. Allow the motor to cool at least 45 minutes then press the Pump Reset Switch.
C. Pump blockages are usually caused by sediment buildup in the pump due to improperly sized or installed filter paper and failure to use the crumb screen. Call a FAS.
The blockage may be caused by sediment buildup or, if solid shortening is used, solidified shortening in the tube. Use a thin, flexible wire to remove the blockage. If the blockage cannot be removed, call a FAS.
A. If using filter paper or pad configuration, verify that filter screen is in bottom of pan with paper or pad on top of screen.
Verify that
If using Magnasol filter assembly, verify that
B. See filter section on page
