Section 6: System Troubleshooting
Problem:
No fluid is being recovered but system cycles and gauge indicates pressure generation.
Solution:
 Inspect product hose for kinks and blockage. Replace if needed. If freezing conditions have
occurred check the discharge lines for frozen product.
 The solenoid could be stuck. If it is locked up it may be cleared by depressing the small button
on the black end of the solenoid using a small Phillips screwdriver or paper clip to actuate the
solenoid manually. If this doesn’t work, remove the small plate at the other end of the solenoid
and clean the plunger and plunger cavity using the procedure found in Section 5.
 Visually inspect the wiring connections to see that they are not loose or otherwise compromised.
Problem:
System cycles but gauge does not indicate pressure generation.
Solution:
 Inspect tubing for abrasion, cuts or open connections. Replace if needed.
 Make sure the air line connection is connected to the pump.
 Verify that there is fluid in the well.
 Open the controller panel and verify that all air line connections are intact.
Problem:
A pump is stuck in pressure.
Solution:
 Inspect the solenoid for residue or debris. If it is locked up it may be cleared by depressing the
small button on the black end of the solenoid using a small Phillips screwdriver or paper clip to
actuate the solenoid manually. If this doesn’t work, remove the small plate at the other end of
the solenoid and clean the plunger and plunger cavity using the procedure found in Section 5.
