TABLE 2. PUMP TROUBLESHOOTING
SYMPTOM | POSSIBLE PROBLEM | SOLUTION | |
|
|
| |
|
| Check that proper voltage (115 VAC 1Ø) is being supplied to the | |
| Incorrect voltage/amps? | pump. Also check that there is an adequate amount of current | |
|
| (amps) to run the pump. Check power source circuit breaker. | |
|
|
| |
Pump Fails To Start | Check electrical connections? | Inspect power cord. | |
|
| ||
Blown fuse or defective circuit | Replace fuse or circuit breaker. Check cause of blown fuse or tripped | ||
| |||
| breaker? | circuit breaker. | |
|
|
| |
| Impeller locked? | Disconnect power cord and check for clogging and improper impeller | |
| clearance. Unclog pump. Check overload protection device. | ||
|

| |
| Twisted or restricted discharge | Lay hose flat | |
| hose? |
| |
|
|
| |
Pump Fails to Deliver Full | Clogged pump strainer? | Clean strainer. | |
|
| ||
Output |
| Use a voltmeter to check voltage while pump is energized. Voltage | |
|
| ||
| Low voltage? | must be within ±10%. Check power source (no load and load). If an | |
| extension cord is used, make sure it has adequate | ||
|
| ||
|
| capacity for the required length. | |
