reset button must be pressed to reactivate the unit.
Blocked Intake Clear or replace pump intake screen.
Blocked Discharge Remove blockage in plumbing.

lights section below.
Worn Pump Replace worn pump parts and recalibrate.
Yellow Flashing Light
Stalled Motor Repair or replace motor. Pump may be sand or mud locked.
Float Switch
A bobbing fl oat switch can cause two-wire motors to stall. Arrange plumbing to avoid
splashing water. Replace fl oat 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-Plus will try to restart the motor every two
minutes until 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
Press and release the reset button to restart the unit. A bobbing fl oat switch may cause the
unit to detect a rapid cycle condition on any motor or an overload condition on 2-wire
motors. Try to reduce water splashing or use a different switch.
