Solution
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.
Clean or replace pump intake screen.
Remove blockage in plumbing.
Replace check valve.
Replace broken parts.
Machine gun rapid cycling can cause an underload
condition. See flashing red and yellow lights section
below.
Replace worn pump parts and recalibrate.
Repair or replace pump motor. Pump may be sand or
mud locked.
A bobbing float switch can cause two-wire motors
to stall. Arrange plumbing to avoid splashing water.
Replace float switch.
Check insulation resistance on motor and control box
cable.
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.
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.
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.
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.
Replace damaged pipes or repair leaks.
Failed valve will not hold pressure. Replace valve.
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.
