Hayward Color Logic Problem

[matt4x4]

The color logic is LED's, it's supposed to give you 15 seconds of white before it goes into it's little routine.
Is the white on for about 15 seconds before you get your almost nothing glow?
It sounds like there's a fault with the internal processor, have you tried to reset it according to your manual?

You can get the manual on line if you do not have it.
If you have one of the newer models, the closest issue would be related to "dimming" which is somewthing not supposed to be done, it is controlled by your Hayward pool/spa controller (dip switch 1 down) and it could be as simple as a dirty dip switch that nedds to be flicked back and forth a couple of times to clean the dirt or corrosion off it.
Another problem could be a dirty (corroded) connection in your junction box.
