Possible Causes

Water ingress into motor windings, Damaged power cable or plug, Shorted motor winding, Faulty internal drive electronics on variable speed models

How to Fix / Troubleshooting

Safety first: Do not repeatedly reset a breaker that trips instantly. There may be a dangerous fault. Isolate power and keep the pump off until inspected.

Step-by-step checks (visual only):

  • 1. Inspect cable and plug: Look for cuts, crushed sections, or burn marks on the Davey pump supply cable and plug.
  • 2. Check motor for water: Look for obvious water inside the motor terminal box or around the cable entry gland.
  • 3. Smell for burning: A strong burnt smell from the motor or controller indicates internal damage.

Electrical testing (insulation resistance, winding resistance) must be done by a licensed electrician or pump technician. In most cases, a motor or drive replacement is required.
