What to do if my ITT Water Pump runs but the motor protection trips?
- R
  Rebekah WilsonAug 11, 2025
  If your ITT Water Pump motor protection trips, consider these potential issues: * The motor protection might be set too low. Adjust it according to the data plate and cable chart, if available. * The impeller may be difficult to rotate. Clean the impeller and the sump, and check that the impeller is properly trimmed. * The drive unit may not be receiving full voltage on all three phases. Check the fuses and replace any that have tripped. If the fuses are intact, contact a certified electrician. * There may be a malfunction in the overload protection. Replace the overload protection.

What to do if ITT Flygt 5150.350 Water Pump does not stop when a level sensor is used?
- M
  Marissa EatonAug 23, 2025
  If your ITT Water Pump doesn't stop when a level sensor is used, here are a few things to check: * The pump might be unable to empty the sump to the stop level. Ensure there are no leaks from the piping or discharge connection, the impeller isn't clogged, the non-return valves are functioning properly, and the pump has adequate capacity. For more help, contact a local ITT service shop. * There could be a malfunction in the level-sensing equipment. Clean the level regulators, check their function, check the contactor and the control circuit, and replace any defective items. * The stop level might be set too low. Raise the stop level.

Why ITT Flygt 5150.350 starts-stops-starts in rapid sequence?
- M
  Mary KramerAug 28, 2025
  If your ITT Water Pump starts, stops, and starts in rapid sequence, here are potential causes: * The pump may be starting due to back-flow, which refills the sump to the start level again. Ensure the distance between the start and stop levels isn't too small, the non-return valves work properly, and the rinser isn't too long without a non-return valve. * The self-holding function of the contactor might be malfunctioning. Check the contactor connections, the voltage in the control circuit in relation to the rated voltages on the coil, the functioning of the stop-level regulator, and whether the voltage drop in the line at the starting surge causes the contactor's self-holding malfunction.
