Problem
Possible Cause
Corrective Action
Red light blinks: locked,
overload, overheat
Definition: when the overload is
detected for the first time, the
motor stops immediately, and
starts again 20 seconds later.
Repeat the detection for three
times until it stops completely
after overload.
Impeller blocked or debris goes
around impeller.
Disassemble pump and clean debris.
Blue light blinks: dry run
Definition: when no-load is
detected for the first time, the
motor stops after 40 seconds of
operation, and starts again after
20 seconds. This is repeated for
3 time, and stops completely
after 3 times of no load.
1. Did not prime.
1. Please fill water into pump to prime.
Yellow light blinks: Rapid
cycle.
Definition: It is detected that the
motor has started 20 times within
1 minute, and it will stop
immediately.
1. The tank was pre-charged
incorrectly.
2. There is a ruptured
diaphragm/bladder (pre-charged
tank)/or has no air cushion.
3. The pipes are leaking.
4. The foot valve leaks.
5. The pressure switch is not
adjusted correctly.
6. The air charge is too low in the
pre-charged tank.
1. Add or release air as needed.
2. Replace the tank/refill the air.
3. Repair the pipe connections or
replace the pipes.
4. Repair or replace the foot valve.
5. Closely look at the pressure gauge to
see the pump On/Off points are
around 30 psi/50 psi. If not, adjust or
replace the pressure switch.
6. DISCONNECT POWER and open
faucets until all pressure is relieved.
Using tire pressure gauge, check air
pressure in the tank at the valve
stem located on the tank. If less than
pressure switch cut-in setting (30
psi), pump air into the tank from an
outside source until air pressure is 2
psi less than the cut-in setting of the
switch. Check the air valve for leaks
(use soapy solution) and replace
core if necessary
Green breathing light: Standby
