TROUBLESHOOTING
PUMP DOES NOT START:
Impeller bound-up — Insert screwdriver in slot of shaft at motor's
rear end bell and rotate clockwise.
No electrical power to pump or low voltage — With a voltage
tester, check power to pump. The pump must have full voltage
checked while pump is running. If it hasn't started, see wire
size recommendations and check for poor or corroded electrical
connections. Check for a blown fuse or tripped circuit breaker.
PUMP RUNS BUT DOES NOT PUMP:
Lack of priming — Check all plumbing connections to ensure they
are airtight. If a waste deck plate is connected to pump suctions
hose by a "Tee" fitting, the deck plate must also be airtight.
Worn impeller* — Replace flexible impeller.
*A worn impeller may be a likely cause if the Run-Dry Protection
Device has often been allowed to shut-off the pump.
After long periods of nonuse, the flexible impeller may stick to the
pump body preventing the macerator pump from turning freely.
If this occurs, the impeller can be broken free by removing the
rubber cap on the shaft at the rear end of the motor, inserting a
screwdriver in the slot and rotating the shaft clockwise a quarter
turn or more. When impeller is broken free, reinstall the plastic
cap on the motor shaft.
