Symptom | Possible Cause(s) | Corrective Action |
|
|
|
Pump will not start or run
1. Water level too low | 1. Pump switch will not turn on unless water covers top of |
| pump |
2. Blown fuse or tripped circuit | 2. If blown, replace with proper sized fuse or reset breaker |
breaker |
|
3. Low line voltage | 3. If voltage is under recommended minimum, check wiring |
| size from the main switch on property. If OK, contact |
| power company. |
4. Defective motor | 4. Return for service or replace motor |
5. Defective float switch | 5. Replace float switch |
6. Impeller (pump filled with | 6. If impeller will not turn, remove housing and remove |
debris) | debris |
7. Tangled switch | 7. Arrange switch so the switch moves freely. Reposition |
| pump if necessary |
8. Insufficient liquid level | 8. Make sure liquid level is at least 13" from the basin floor |
Pump starts and stops too often
1. Backflow of water from piping | 1. Install check valve |
2. Faulty float switch | 2. Replace float switch |
3. Check valve not installed or | 3. Remove and examine check valve for proper installation |
leaking | and free operation |
4. Discharge head is less than | 4. Recheck all sizing calculations to determine proper pump |
manufacturer’s minimum | 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
1.Pump should not be used for water above 120°
2.Replace or reposition pump
Pump may start unexpectedly. Disconnect power supply
before servicing
|
| 3. Low line voltage | 3. If voltage is under recommended minimum, check wiring |
|
|
| size from the main switch on property. If OK, contact |
|
|
| power company |
|
|
|
|
| Pump operates noisily | 1. Worn bearings | 1. Return for service or replace |
| or vibrates excessively | 2. Debris in impeller cavity or | 2. Remove housing, clean impeller and/or replace broken |
|
| broken | impeller |
|
| 3. Piping attachments to building | 3. Replace portion of discharge pipe with flexible connector |
|
| structure too rigid or too loose |
|
|
|
|
|
| Pump will not shut off | 1. Defective float switch | 1. Replace float switch |
|
| 2. Float switch movement restricted | 2. Reposition pump or clean basin as required to provide |
|
|
| adequate clearance for float |
|
| 3. Restricted discharge (obstruction | 3. Remove pump and clean pump & piping |
|
| in piping) |
|
|
| 4. Excessive inflow or pump not | 4. Recheck all sizing calculation to determine proper pump |

| properly sized for application | size |
|
|
|
|
| Pump operates but | 1. Low line voltage | 1. If voltage is under recommended minimum, check wiring |
| delivers little or no |
| size from the main switch on property. If OK, contact |
| water | 2. Debris caught in impeller or | power company |
|
| discharge | 2. Remove, clean and check for tightness |
|
| 3. Worn or defective pump parts or | 3. Replace worn parts or entire pump. Clean parts if required |
|
| plugged impeller |
|
|
| 4. Pump running backwards | 4. Check rotation. (CCW from bottom) Return if CW |
|
| 5. Pump not properly sized for | 5. Recheck all sizing calculations to determine proper pump |
|
