Solution
Pump Fails To Start
Incorrect voltage/amps?
Check that proper voltage (115 VAC
1Ø) is being supplied to the pump.
Also check that there is an adequate
amount of current (amps) to run the
pump. Check power source circuit
breaker.
Check electrical connections?
Inspect power cord.
Blown fuse or defective circuit
breaker?
Replace fuse or circuit breaker. Check
cause of blown fuse or tripped circuit
breaker.
Impeller locked?
Disconnect power cord and check
for clogging and improper impeller
clearance. Unclog pump. Check
overload protection device.
Pump Fails to Deliver Full Output
Twisted or restricted discharge hose? Lay hose flat un-kinked. Remove clog
from hose line.
Clogged pump strainer?
Clean strainer.
Low voltage?
Use a voltmeter to check voltage
while pump is energized. Voltage must
be within ±10%. Check power source
(no load and load). If an extension
cord is used, make sure it has
adequate current-carrying capacity for
the required length.
