    What causes over current in my EBARA DML and how to fix it?
    • K
      Kim CobbAug 7, 2025
      If your EBARA Water Pump is experiencing an over current, here's what to investigate: * For large fluctuations of power source voltage, request the electric power company for action. * Inspect the connection section and the magnet switch. * Check the nameplate. * If operating the 50Hz pump at 60H, establish the correct rotational direction. * Narrow the opening of the gate valve, or if there is no gate valve, replace the pump with one having a lower head. * If the pump caches foreign matter, disassemble the pump to remove it. * If the motor bearing is broken, repair or replace the bearing.

    What to do if EBARA DML can be operated, but it stops after a while?
    • D
      Daniel WardAug 17, 2025
      If your EBARA Water Pump operates but stops after a while, it could be due to: * Prolonged dry operation causing the Auto-cut to function. In this case, raise the water level. * High liquid temperature triggering the Auto-cut. Try lowering the water level.

    What to do if my EBARA DML does not pump or has insufficient pumping rate?
    • J
      judy73Oct 27, 2025
      If your EBARA Water Pump isn't pumping or the pumping rate is insufficient, here's what you can check: * Ensure the pump isn't running in reverse. You may need to establish the correct rotational direction. * If the operating water level is low, it might be causing air suction. Try raising the water level or lowering the pump position. * Inspect the discharge pipe for any leaks and repair if necessary. * Remove any foreign matter that may be clogging the discharge pipe or adhered to the suction opening. * If foreign matter clogs the pump, disassemble the pump to remove it. * If you find a worn impeller, replace it. * Request the electric power company for action if there is a large voltage drop. * Check the nameplate if you are operating the 60Hz pump at 50Hz. * Review t...
