4. Defective motor
5. Defective switch
6. Impeller (pump filled with debris)
7. Tangled tether switch
(BCSE50T & BCSE50M)
8. Insufficient liquid level
Pump starts and 1. Back flow of water from piping
stops too often 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
Pump shuts off 1. Excessive water temperature
and turns on 2. Defective switch or entangled switch is
independently causing pump to run dry
of switch (trips (BCSE50T & BCSE50M)
thermal overload
3. Low line voltage
protection)
Pump operates 1. Worn bearings
noisily or vibrates 2. Debris in impeller cavity or broken
excessively 3. Piping attachments to building
structure too rigid or too loose
Pump will not shut 1. Float switch movement restricted
off
2. Restricted discharge (obstruction in
piping)
3. Excessive inflow or pump not properly
sized for application
4. Defective switch
Pump operates but 1. Low line voltage
delivers little or no
water 2. Debris caught in impeller or discharge
3. Worn or defective pump parts or
plugged impeller

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

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
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
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
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
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
