AquaPure Nature2 SWG- No Flow Sometimes

[rams_man13]

Hello Most Helpful Pool Friends,

I have an AquaPure Nature2 SWG and a iAquaLink system.

My filter pump is on a schedule through the iAquaLink. It comes on at a regular time and shuts off at a regular time.

When it comes on one of 3 things happens:

1) It detects flow and everything is fine and it generates chlorine.

2) It doesn't detect flow, ideally I check sometime shortly after the pump is turned on. I manually flip the pump off and on and it detects flow when it restarts and everything is fine.

3) It doesn't detect flow, I manually flip the pump off and on and it still doesn't detect flow.

Obviously the goal would be to have situation 1 happen every time. Which outcome of the three I get seems very random and I can't really figure out what impacts it.

Any ideas?

It sounds like you have a bad flow sensor but find out where it plugs in to the control board and disconnect/reconnect a few times to clean the contact connection before you replace it.

Ok, I think I see where the flow sensor connects.

Is this correct? Unplug and replug in a few times?

I think it's this product: Jandy AquaPure | Fusion Soft Slotted Flow Sensor, 3-Port Cell (16') - R0452501

I'm not sure of the PN but yes, that it the connector.

I think I solved this.

After reading the manual. I have this little dohickey thing here.

My circuit board requires program A to be running. For some reason the last few days it was switched to program B. When I switched it back to Program A, flow was detected.

So, that definitely helps narrow down the problem. Now the question is... does this thing switch to program B randomly. Does it switch back to program A when the filter pump is turned off and on again.

But, I did take apart my SWG today, flow sensor contacts look very clean and the salt cell doesn't have any noticable scaling built up.
