    Why E-one Water Pump is not operating and the alarm is on?
    • E
      elizabethlynchJul 31, 2025
      If your E-one Water Pump is not operating and the alarm is on, there could be several reasons. First, check the voltage at the alarm panel and ensure it matches the voltage listed on the pump's nameplate, staying within a 10% range (216V to 264V). If you're using 208V, you'll need a buck boost transformer to increase the power to 240V. Another potential cause is a plugged equalizer tube, so inspect it to ensure it's not crimped or pinched. Also, check the tank for sufficient fluid to operate the pump. The pump operation depends on the water level inside the tank. Insufficient fluid may indicate a problem with the alarm wiring, alarm sensing line, or alarm switch. See Chapter 7 – Level Sensor.

    What to do if E-one Extreme is running but not pumping?

      If the E-one Water Pump is running but not pumping and the alarm is on, it could be due to a blocked discharge line, a worn stator, or a leak in the pump discharge assembly. First, check the amperage. If it's high (8 amps or higher), turn off the pump and inspect the discharge line for blockages. Disconnect the discharge piping and recycle the fluid in the tank to confirm the pump isn't damaged. Turn the pump back on and check the amperage again. If it remains high, replace the pump. If the amperage is low (4.9 amps or less), the pump must be pulled and the Stator (and possibly the Rotor) replaced, or the leaking discharge line repaired. Determine and correct the cause of the Stator and/or Rotor failure before reinstallation.

      If the E-one Water Pump is not operating and the alarm is on, start by checking the voltage at a location nearest the pump, such as the junction box or electrical quick disconnect (EQD) plug. The correct voltage is listed on the pump nameplate, and it must be within 10 percent of the nameplate voltage (207 to 264V for a 230 - 240V pump). You can also perform a continuity check. Inspect the electrical controls and replace any wet or corroded components. Also, test the controls.

      If your E-one Water Pump is running, but not pumping, and the alarm is on, start by checking the amperage. If it's high (8 amps or more), immediately turn off the pump and inspect the discharge line for any blockages. To rule out pump damage, disconnect the discharge piping and recycle the fluid in the tank, then turn the pump back on and check the amperage again. If it remains high, the pump likely needs replacing; return the old one for potential repair. If the amperage returns to normal, clear any blockages in the discharge line and re-check the amperage. If the amperage is low (4.9 amps or less), the pump must be pulled and the stator (and possibly the rotor) replaced. Also, visually inspect the Check/Anti-siphon valve for cracks and the discharge line for ruptures, repairing or replac...

    Why is my E-one Water Pump so noisy?
    • K
      kalvaradoNov 8, 2025
      If the E-one Water Pump is noisy, it may be due to several reasons. It could be normal operation where the pump is grinding up material; wait a few minutes to see if it quiets down, and if not, remove the core and clean the basin. Alternatively, low voltage could be the issue; check the voltage level against the pump nameplate (it should be within 10 percent of the specified voltage, i.e. 207V to 264V for a 230-240V pump). A blocked discharge can also cause noise; check the amperage, and if it's high (8 amps or higher on 230 - 240V), turn off the pump and inspect the discharge line for blockages. If the amperage remains high after clearing any blockages, replace the pump. Damaged Stator or Worn Motor Bearing could also be the reason. Remove the pump Stator and hand–rotate the shaft. If the...

    Why does the alarm activate frequently on my E-one Extreme Water Pump?
    • D
      Dennis RivasNov 13, 2025
      If the alarm on your E-one Water Pump activates frequently, several factors could be the cause. It might be due to high flow, where the incoming flow exceeds the pump's capacity, often caused by infiltration, sump pumps, or hot tubs. Another cause could be a plugged vent or equalizer tube; inspect and replace the equalizer tube if it's kinked or damaged. A level sensor leak can also trigger frequent alarms; inspect the level sensors for cracks and debris and test for leaks. Also, line blockage or a worn stator can be the reason. Check the amperage. If the amperage is high, look for a line blockage. If the amperage is low, inspect the Stator for excessive wear. Finally, underground wire damage might be the culprit; inspect the tray cable wiring for cuts, breaks, and shorts, using a meg-ohm ...
