Question about Hayward Easy Clear 40 Sq Ft Cartridge Pool Filter with Pump

1 Answer

I own a hayward easy clear pool filter model c-400. My problem is that after awhile the head is very very dificult to remove by unscrewing the head from the base to change the filter. And it just as difficult to close the head to the point where it clicks into place. Is there a proceedure for greasing the threads or cleaning the heads to provide a smother and easier turning of the head from the base. Thank you

The gasket on the head may have swelled and is making it very hard to remove. Try replacing the gasket

Hayward pool filter

Copy following link to access Hayward pool filter manuals: Each manual has a troubleshoot section.... and troubleshoot is about the same for different models of sand filter.
Your filter has Intermatic timer, and you tried the override lever with no luck... Check if circuit breaker is supplying power. Flip breaker fully off, and then fully back on.

Also I see that Intermatic timer has plastic cover over the terminals ... be sure wiring terminals are always covered by clear insulator for safety.

Add a comment for followup.
