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

Failed circulation pump motor, Air lock in circ pump, Blocked suction or return line, Failed relay or output on control board

Safety: Turn off power before touching the pump or plumbing.

Listen and feel: With power on, place a hand on the circ pump. If it is silent and not vibrating, it may not be receiving power or is failed.
Bleed air: Loosen the union on the circ pump discharge to release air until water flows, then retighten.
Check for blockages: Inspect suction fittings and any inline strainers for debris.
Replace pump: If the pump receives proper voltage but does not run, replace it with a compatible LA Spas circulation pump.
