Caldera Spas Overcurrent / Circuit Overload

Spa trips household breaker (non-GFCI) under heavy load, such as when multiple pumps and heater run.

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Undersized breaker or wiring for spa’s amperage, Loose connections at breaker or disconnect, Internal short in pump or heater drawing excess current

Critical safety: Electrical work on breakers and service panels must be performed by a licensed electrician.

Verify breaker size: Check that the spa is on a dedicated circuit with the amperage specified by Caldera for your model.
Inspect connections: Have an electrician inspect and tighten all lugs at the breaker, disconnect, and spa terminal block.
Component isolation: A technician can disconnect pumps or heater to determine if a specific component is drawing excessive current.
