Pumptec-Plus and Pumptec with 3-lights
Pumptec-Plus and Pumptec with 3 lights - Troubleshooting After Installation
| Symptom | Possible Cause | Solution |
| Solid Yellow Light | Dry Well | Wait for the automatic restart timer to time out. During the time out period, the well should recover and fill with water. If the automatic reset timer of the Pumptec-Plus is set to the manual position, push the reset button to reactivate the unit. If the reset timer is set to manual in the Pumptec, turn off power for 5 seconds to reset the unit. |
| Blocked Intake | Clear or replace pump intake screen. | |
| Blocked Discharge | Remove blockage in plumbing. | |
| Check Valve Stuck | Replace check valve. | |
| Broken Shaft | Replace broken parts. | |
| Severe Rapid Cycling | Machine gun rapid cycling can cause an underload condition. See flashing red and yellow lights section below. | |
| Worn Pump | Replace worn pump parts and recalibrate. | |
| Flashing Yellow Light | Stalled Motor | Repair or replace motor. Pump may be sand or mud locked. |
| Float Switch | A bobbing float switch can cause two-wire motors to stall. Arrange plumbing to avoid splashing water. Replace float switch. | |
| Ground Fault | Check insulation resistance on motor and control box cable. | |
| Solid Red Light | Low Line Voltage | The line voltage is below 207 volts. Pumptec and Pumptec-Plus will try to restart the motor approximately every two minutes until the line voltage is normal. |
| Loose Connections | Check for excessive voltage drops in the system electrical connections (i.e. circuit breakers, fuse clips, pressure switch, and Pumptec-Plus L1 and L2 terminals). Repair connections. | |
| Flashing Red Light | High Line Voltage | The line voltage is over 253 volts. Check line voltage. Report high line voltage to the power company. |
| Flashing Red and Yellow Lights | Rapid Cycle | The most common cause for the rapid cycle condition is a waterlogged tank. Check for a ruptured bladder in the water tank. Check the air volume control or snifter valve for proper operation. Check setting on the pressure switch and examine for defects. |
| Leaky Well System | Replace damaged pipes or repair leaks. | |
| Stuck Check Valve | Failed valve will not hold pressure. Replace valve. | |
| Float Switch | A bobbing float switch may cause the unit to detect a rapid cycle condition on any motor or an overload condition on 2-wire motors. To reset a Pumptec, remove power for 5 seconds. To reset a Pumptec-Plus, press and release the reset button. To eliminate float switch bounce, try to reduce water splash or use a different switch. |
