One or more jets have completely stopped flowing while others work normally.

Safety first: Turn off power at the GFCI breaker before removing jets.

• 1. Check seat shut-offs: Some PDC Spas seats have individual air or water shut-off valves. Ensure they are fully open.
• 2. Remove the jet: Rotate the affected jet counterclockwise until it releases, then pull it out.
• 3. Clean jet and body: Rinse the jet under running water and remove any debris. Inspect the jet body in the shell for obstructions and flush if possible.
• 4. Replace worn jets: If the jet internal is cracked, swollen, or will not stay in place, replace it with a PDC Spas-compatible jet insert.
