What to do if the FLYGT 3085 Water Pump motor protection trips?
- K
  Kelly MorrisAug 3, 2025
  If the motor protection trips, it could be due to several reasons. First, ensure the motor protection is set correctly according to the data plate and cable chart. If the impeller is hard to rotate, clean the impeller and the sump, and check the impeller trimming. Also, verify that the drive unit receives full voltage on all three phases by checking and replacing any tripped fuses. If issues persist or phase currents vary, consult a certified electrician or your local sales and service representative. Replacing the overload protection may also resolve the issue.

How to troubleshoot a FLYGT 3085 Water Pump that does not start?

  If the pump doesn't start, first check if an alarm signal has been triggered on the control panel. Ensure the impeller rotates freely, the sensor indicators aren't showing an alarm, and the overload protection hasn't tripped. If the pump starts manually but not automatically, examine the start level regulator for proper function (clean or replace if needed), check all connections, relay and contactor coils, and verify the control switch (Man/Auto) makes contact in both positions. Inspect the control circuit and its functions as well.

Why is my FLYGT 3085 Water Pump delivering too little or no water?
- J
  James AdamsAug 15, 2025
  If your pump delivers too little or no water, several factors could be responsible. Check if the impeller rotates in the correct direction; for a 3-phase pump, transpose two phase leads. Ensure the valves are correctly positioned, resetting or replacing them if necessary, and verify correct installation according to media flow and proper opening. Clear any obstructions in the pipes and seal any leaks in pipes and joints. Also, clean the impeller and the sump if the impeller is difficult to rotate. Replace worn parts on the impeller, pump, and casing. Finally, check the liquid level and level sensor settings, adding a priming means like a foot valve if needed.

What to do if FLYGT 3085 doesn't stop with level sensor?
- B
  benjamingillAug 21, 2025
  If the pump doesn't stop when a level sensor is used, it could be because the pump can't empty the sump to the stop level. Check for leaks in the piping or discharge connection, ensure the impeller isn't clogged, and verify the non-return valves function correctly. Also, make sure the pump has adequate capacity. Additionally, there may be a malfunction in the level-sensing equipment. Clean the level regulators, check their function, and inspect the contactor and control circuit, replacing any defective items. Lastly, ensure the stop level isn't set too low and raise it if needed.

Why does my FLYGT 3085 start and stop rapidly?
- M
  Melissa JohnsonAug 27, 2025
  The pump might be starting and stopping rapidly because back-flow refills the sump to the start level. Verify that the distance between the start and stop levels is sufficient, the non-return valves are working properly, and the discharge pipe between the pump and the first non-return valve is sufficiently short.
