Artesian Spas Keypad Matrix Failure / Water-Damaged Membrane

Some buttons on the topside control panel do not respond or activate wrong functions

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

Worn or cracked keypad overlay, Moisture under membrane, Damaged keypad ribbon cable

Safety: Turn off power at the GFCI breaker before working on the topside.

Inspect overlay: Look for cracks, bubbles, or lifting edges on the keypad surface that could allow water in.
Dry area: If minor moisture is present, gently dry the area and allow the panel to sit in a warm, dry environment for 24 hours, then retest.
Check cable: Ensure the ribbon cable is not pinched or damaged where it passes through the spa shell.

Persistent button issues usually require replacement of the entire topside control panel with an Artesian-compatible unit.
