LA Spas Topside Control Failure or Communication Loss

Topside control panel is completely blank but pumps may still run on a schedule, or nothing responds.

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 topside control panel, Damaged topside cable, Loose connector at control board, Control board communication circuit fault

Safety: Turn off power before unplugging or plugging any control cables.

Check cable connection: Open the control box and locate the topside control cable connector. Unplug and replug it firmly.
Inspect cable: Follow the cable from the topside to the pack, looking for cuts, pinches, or rodent damage.
Test with replacement panel: If available, connect a known‑good LA Spas topside to determine if the original panel is faulty.

If a good panel does not restore function, the control board likely needs replacement.
