I replaced mine several years ago - actually had mine rebuilt by a shop in California. Other here have replaced theirs as well. Not a difficult job:
Trip the 100 amp breaker so no voltage to the pump
Disconnect the cables from the solenoid and pump
2 bolts as I recall removes the motor
There is a part number on the motor - replacement costs $700 to $1000+.
Here's Lippert's replacement:
