PUMPTEC-PLUS Pump Protection System
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 switch is set to the
manual position, then the reset button must be pressed to
reactivate the unit.
Blocked Intake Clean or replace pump intake screen.
Blocked Discharge Remove blockage in plumbing.
Check Valve 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 pump 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
Step C of the calibration instructions indicates that a
flashing green light condition will occur 2 to 3 seconds
after taking the Snapshot of the motor load. On some two-
wire motors, the yellow light will flash instead of the green
light. Press and release the reset button. The green should
start flashing.
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.*
The Pumptec-Plus will try to restart the motor every two
minutes until line voltage is normal.
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 the 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 float switch may cause the unit to detect a rapid
cycle condition on any motor or an overload condition on
two-wire motors. Try to reduce water splashing or use a
different switch.
*Report high or low line voltage to the power company.
