Pentair Pentair IntelliBrite 5G LED Pool/Spa Light DIM/FLICKER Error Fix: Dimming or Flickering

Error code DIM/FLICKER on the Pentair Pentair IntelliBrite 5G LED Pool/Spa Light means: Dimming or Flickering. The IntelliBrite LED light is flickering, dimming, or has intermittent brightness changes. Common causes include a loose bulb connection (the LED lamp inside the fixture), water intrusion into the fixture lens, a corroded light niche junction, voltage drop on long wire runs from the transformer/automation panel to the pool light niche, or a failing LED driver circuit inside the lamp. Check voltage at the light niche junction box — should be 12V AC (for 12V fixtures) within 10 percent. Tighten or reseat the lamp. If water is inside the lens, the lens gasket has failed. Replace the lamp or fixture.
