PUMP PROTECTION AND DIAGNOSTICS
The Well-X1
®
continually monitors pressure, cycle time and voltage to protect the well pump. The following error codes
alert the user to a potential problem, prompting service. When an error occurs, the display will flash a diagnostic code.
WELL-X1 ERROR CODE
POSSIBLE CAUSES AND CONTROL ACTION
E1: Rapid Cycle
Multiple cycles below a safe runtime indicate an incorrect precharge,
undersized Well-X1 or waterlogged tank. Pump continues to run.
E2: Low Suction
Pump operation below 10 psi indicates a low well level, well piping leak,
insufficient prime, failing pump or loose wiring. Pump will shut down and
attempt to restart every 60 minutes.
E3: Voltage Protection
If line voltage varies outside a safe operating range, low or high, the control will
run for up to two minutes to ensure water is available, then shut the pump off
until voltage is restored to a normal range.

4. Pressure setting out of range
5. Incorrect wiring
1. Adjust pump cut-in and cut-out setting as described in manual.
2. Ensure shut-off valves are open, check any filtration equipment.
3. Check well pump.
4. Reduce pressure settings within pump capacity.
5. Check pump wiring.
Intermittent water interruption
1. Tank precharge too high
2. Recurring error
1. Adjust air pressure 2 psi below cut-in setting.
2. See Error Code section for possible causes.
No pressure (pump runs)
1. No pump prime (jet pumps)
2. Failing well pump
3. Incorrect wiring
1. Prime pump and restart.
2. Repair or replace as necessary.
3. Check pump wiring.

5. Check pump wiring.
Pump will not shut off
1. Pressure setting too high
2. Pump water line obstructed
3. Pump problem
4. Failed control
1. Decrease pressure settings until pump and reach cut-out.
2. Ensure no shut-offs are closed between pump and Well-X1
™
.
3. Inspect pump and sizing if cut-out not reached.
4. Replace.
Sediment or discoloration in water 1. Poor water quality
1. Install proper treatment equipment, drain and flush tank per
instructions contained in this manual.
Rapid pump cycling
1. Differential too narrow
2. Improper precharge
3. Failed tank
1. Check sizing for intended operating range or spread differential
to obtain proper pump run time.
2. Adjust air pressure 2 psi below cut-in setting.
3. Replace.
Relief valve discharges
1. Over-pressure condition
2. Faulty relief valve
1. See "Pump will not shut off" above.
2. If pressure is below 100 psi, relief valve should not open. Replace.
