no flow

The Hurlcon VX chlorinator is more than 10 years old. It always says low salt which I think it's true because I didn't add enough salt to the pool after heavy rains. The chlorinator works properly despite the low salt warning. A few days ago I added 1 bag of salt to the pool. After a while I...

Hi TFP, Went from pool novice to having a trouble free pool a couple years ago when I bought my first place with a pool and this forum was awesome with examples and assistance. Nowadays people remark on how little effort it is I spend taking care of my pool -- a 12,000 gallon in-ground jobbie...

I've got an older Aqua Trol system. I used it fine last season. This year when I power it on, I'm getting a power light and the No Flow light. This is the Return Jet (RJ) model, so it isn't supposed to have a flow sensor, so I'm not sure what would send the no flow signal anyway. For what it's...

First time post, been reading ever since we moved to our home with a TruClear by Jandy. I replaced the cell last year when it seemed like the problem was the cell (was about 4 years old). $400 later, I am faced with a constant "No Flow" indication anytime I am running. Flow is normal, I have...

Pulled the pump out and setup the pool for the year. Have some issues. Put in new sand this year. Same bag as last year but wanted a clean setup. Got everything attached and working but handle was very hard to rotate. Resolved this by disassembling and cleaning out sand debris. Once back...

I had a company install a pool Fall 2020 that pretty much dug a hole, dropped in a fiberglass form, installed the equipment (Jandy cartridge filter, variable speed pump, and TruClear chlorinator) they happened to have. I arranged the rest, which has been difficult but doable. It was the only way...

Hooked up automation cable to a Hayward Sp32950VSP and switched the filter pump to VSP with flow monitoring "enabled". However, I'm getting a No Flow error. Prior to hooking up the automation the pump ran for two weeks without issue. I was waiting on a modbus adapter for the controller and...

So I had recently purchases a home with a pool and have been having flow issues consistently since opening. I tried backwashing a few times and rinsing, but nothing improved. The jets in the pool are very weak when on the filter setting but worked better when set to recirculate. Finally, I...

Hi all! I am looking for the possible cause and hopefully even a solution. Knowing the cause however will go a long way in me coming up with a solution. I have 4 deckjets. They are all on the same leg of plumbing. In addition, they were installed in a loop so that they all receive the same...

I'm trying to determine if i need to purchase a new main board GLX-PCB-PRO for my Hayward Pro Logic Automation system. All functions seem to operate correctly except I have a constant no flow message and an inability to do any of the salt functions. I’ve replaced the flow switch but that did...
