Troubleshooting Chart
Symptôm Possible Cause(s) Corrective Action
Pump will not start
or run 1. Water level too low
2. Blown fuse or tripped circuit breaker
3. Low line voltage
4. Defective motor
5. Defective switch
6. Impeller (pump filled with debris)
7. Tangled tether switch
(BCSE50T & BCSE50M)
8. I nsufficient liquid level
1. Pump switch will not turn on unless water covers top of pump
2. If blown, replace with proper sized fuse or reset breaker
3. If voltage is under recommended min i mum, check wiring size from the
main switch on property. If OK, contact power company.
4. Return for service or replace motor
5. Replace float switch
6. If impeller will not turn, remove housing and remove debris
7. Arrange switch so the switch moves free ly. Re po si tion pump if
necessary
8. Make sure liquid level is at least 13 inches from the basin floor
Pump starts and
stops too often 1. Back flow of water from piping
2. Dirty capacitive water sensor
3. Faulty float switch
4. Check valve not installed or leaking
5. Discharge head is less than
manufacturer's minimum
1. Install check valve
2. Reposition pump, clean sensor face
3. Replace float switch
4. Remove and examine check valve for prop er in stal la tion and free
operation
5. Recheck all sizing calculations to determine proper pump size
Pump shuts off
and turns on
independently
of switch (trips
thermal overload
protection) 1. Excessive water temperature
2. Defective switch or entangled switch is
causing pump to run dry
(BCSE50T & BCSE50M)
3. Low line voltage
1. Pump should not be used for water above 120º F
2. Replace or reposition pump
Pump may start unexpectedly. Disconnect
power supply before ser vic ing.
3. If voltage is under recommended min i mum, check wiring size from the
main switch on property. If OK, contact power company
Pump operates
noisily or vibrates
excessively 1. Worn bearings
2. Debris in impeller cavity or broken
3. Piping attachments to building
structure too rigid or too loose
1. Return for service or replace
2. Remove housing, clean impeller and/or replace broken impeller
3. Replace portion of discharge pipe with flexible connector
Pump will not shut
off 1. Float switch movement restricted
2. Restricted discharge (obstruction in
piping)
3. Excessive inflow or pump not properly
sized for application
4. Defective switch
1. Reposition pump or clean basin as required to provide adequate
clearance for float
2. Remove pump and clean pump & piping
3. Recheck all sizing calculation to determine proper pump size
4. Replace float switch
Pump operates but
delivers little or no
water 1. Low line voltage
2. Debris caught in impeller or discharge
3. Worn or defective pump parts or
plugged impeller
4. Pump running backwards
5. Pump not properly sized for application
6. Check valve stuck closed or installed
backwards
7. Shut off valve closed
1. If voltage is under rec om mend ed minimum, check wiring size from the
main switch on prop er ty. If OK, contact power company
2. Remove, clean and check for tight ness
3. Replace worn parts or entire pump. Clean parts if required
4. Check rotation. (CCW from bottom) Return if CW
5. Recheck all sizing calculations to determine proper pump size
6. Remove and examine check valve for proper installation and free
operation
7. Open valve
