Spa water is cloudy and does not clear with normal filtration.

Safety first: No need to open electrical components.

• Clean or replace filter: Rinse the filter thoroughly or replace if more than 1 year old.
• Increase filtration cycles: Extend filter cycle durations in the control settings.
• Shock and clarify: Shock the spa and use a clarifier to help the filter capture fine particles.

Persistent cloudiness may indicate the need for a full drain, line flush, and refill.
