CODE
REASON
ACTION
SOLUTION
E1
Rapid cycle
Excessive amp draw
Pump continues to operate.
See “Pump Starts Too Often” above.
Have pump checked for proper operation.
E2
Insufficient water
supply running pressure
below 10 PSI
Shuts off pump. Auto restart
after 60 min.
1. Determine cause of insufficient water supply.
2. Ensure supply valves are fully open.
3. Inspect pump.
E3
Improper voltage
Shuts off pump.
Restore voltage to proper range. Pump automatically
restarts with proper voltage.
E4
Power disturbance
Shuts off pump.
Disconnect power for one minute. Replace control if
error persists.
To reset control at any time, press
buttons simultaneously for 5 seconds.
To “invert” the display for easier viewing, press
together for 3 seconds.
The digital control incorporates built-in diagnostics. If the unit is not functioning properly or is inoperable, look for an
error code (example E1) on the digital readout before proceeding. Error codes are listed in the table at the bottom of
this page.
PROBLEM
CAUSE
SOLUTION
Pump will not start.
1. No Power.
2. Faulty wiring.
3. Damaged motor.
4. Damaged control.
1. Check circuit breaker and fuses, tighten connections.
2. Check wiring per installation diagram in this booklet. If pump
hums, but will not start, check pump motor wiring.
3. If display illuminates with no error code, but pump will not start,
replace pump.
4. If power is present at control but display is blank, replace control.
Pump runs but will
not build pressure.
1. Supply closed/blocked.
2. Bypass loop open.
3. Pump plumbed backwards.
4. Bad internal parts.
1. Open all supply valves, ensure check valve is not sticking, clean
any filters.
2. Close bypass valve.
3. Reverse inlet/outlet.
4. Check for bad seals or broken impeller. Repair or replace as
necessary.
Pump builds pressure
but will not shut off.
1. Operating pressure set too high.
2. Bad internal parts.
3. Control line blocked.
1. Reduce control setting as necessary.
2. Check for bad seals or broken impeller. Repair or replace as
necessary.
3. Remove control line and blow compressed air to clear.
Pump starts too
often (cycles under
30 sec.).
1. Control differential too narrow.
2. Tank precharge incorrect.
3. Waterlogged pressure tank.
1. Set cut-in and cut-out 20 psi apart.
2. Set air pressure 2 psi below cut-in while pump is off and water
pressure is zero.
3. If water emerges from tank air stem when depressed, replace tank.
THE DIGITAL CONTROL CONTAINS NO SERVICEABLE PARTS. REMOVAL OF INTERNAL CIRCUIT BOARD COVER
WILL VOID WARRANTY.
