  If your Zoeller Water Pump doesn't start, check the following: * Ensure the circuit breaker isn't off, or the fuse isn't blown or loose. Reset the breaker or replace the fuse. If the issue persists, contact an electrician or plumber. * Confirm the water level in the sump basin is high enough to activate the switch. * Make sure the float can move freely; remove any obstructions.

  If your Zoeller Water Pump runs continuously, it could be because the float is stuck in the ‘on’ position; ensure it can move freely. Alternatively, the float switch may be defective and require replacement.

  Brian FullerAug 27, 2025
  If the fuse blows or the circuit breaker trips when your Zoeller Water Pump starts, it could be due to a few reasons: * The impeller or pump inlet might be clogged; remove the pump from the basin and clean these parts. * The fuse or circuit breaker may be too small; ensure the electrical circuit capacity is 15 amps or higher. * Plug the pump securely into a GFCI outlet that cannot be turned off by a wall switch. * Remove any obstructions around the float.
