No Flow Line REd indicator light

[GreenTerrorPool]

My red light would always be on when the pump was off. As soon as pump started and i had flow it would kick off.

Now the red light is never on, even when the pump is off.

I know it is not a burnt out light by turning off breaker. It works

Any ideas what has caused this?

thanks

Are you talking about your SWCG? If so, it should never have power to it when the pump is not running. So it is wired incorrectly. That needs to be addressed ASAP. The flow switch on the SWCG is a secondary shut off. It should never be relied upon as the primary disconnect.

As far as why the Red light is no longer on, could be a faulty unit. Have you read your operating manual. Called the Tech support for the unit?

Take care .

GTP,

I see you have a VS pump, which I assume gets power all the time. So, what interrupts the power to your salt system when the pump is not running??? As Marty points out, it sounds like your system is not wired correctly.

That said, if the flow light used to be on and is now off, logically it can only be three things...

1. The bulb is bad, which you say is not the case.
2. The flow switch has failed in the closed position.
3. The circuit in the controller that "reads" the flow switch position has failed.

If the cell is allowed to generate chlorine, when the pump is off, it could cause the cell to explode. It is not going to blow up your house, but something that you should fix soon...

Thanks for posting,

Jim R.

I have been down the road before with GC on the issue of the SWG power still being on when the pump is off. He even had like the President of Hayward Florida call me and tell me that this is ok due to me not having the control system or something. And he also said i have never seen a flow switch go bad so dont have to worry about this. Well it looks like it was still producing chlorine when the pump is off now that something has failed. Thanks guys and maybe now he will wire it correctly.

Flow switches definitely fail. Keep the salt system off until you can get a new switch.

Part of the problem is that manufacturers really haven't addressed the issue of having a SWG and variable speed pump without automation.

Automation is an answer. The builder should have use AquaPlus or ProLogic instead of the aquarite (blue essence).

A few variable speed pumps include an auxiliary load relay that can control power to a SWG based on pump speed.

The Pentair iChlor can detect IntelliFo pump operation.

For your situation, there's no easy answer.

You don't want to rely only on the flow switch. Here are some ideas:

Add a timer to the SWG and set the on time within the pump runtime window.

You could run the pump continuously at low speed. The power use would be low but you shouldn't have to do this.

Add a current sensing relay that senses when the pump is on before sending power to the SWG.

The timer is probably the easiest answer.

you guys rock. The actual issue of the flow sensor was easily fixed. I unplugged the phone line and plugged it back in and boom it was fixed. But this other issue im still battling with the contractor. Thanks Again!
