Hayward H65 Perflex filter--not bumping and DE sitting at bottom of filter

[sjrbt]

The arm does not move up when the filter starts. I am not getting DE back in the pool. I backwashed it again yesterday and only put 4 cans of DE back in, instead of the recommended 6. I suspect that when I back wash-- all the DE isn't coming out because when I put 6 cans in, the pressure gets too high immediately. Do you think I will hurt the system only putting in 4 cans? I read somewhen on this forum that they suggest putting 80% of the recommended DE in when backwashing because some stays behind.

I can move the arm but it feels like it attached to nothing. I asked my pool guys about it and they suggested the E clip also. But they wanted $75 just to take a look. I am going to take it apart this weekend and hopefully be able to see what is missing if anything.

Where are the e clips and how many should there be?

Thanks for responding

P.S.
When I says "cans" of DE, I mean the container I got at the pool store that measures the DE

Hi, sjrbt and welcome!

If the bump arm doesn't rise as the tank gets full and has no resistance when moved, it's an "E" clip issue for sure!

Let me tell you what to look for, the shaft in the center of the nest is clipped to the plastic plates (tube sheets) and secured to the lid. If you had the little beastie open earlier this season and the shaft didn't fall out, you probably didn't take the tank lid off the shaft, or the shaft would have dropped down.

It sounds like you've had this apart before, so shouldn't need much guidance - but I'll be here anyway, if you have questions once it's open.

I had the same issue on mine, It was the clip $2.25 for a new one and im good again.
A bit of a pain to install the clip, but if you need any help just ask.
Don't forget you will also need a washer that sits above the clip.
