Pentair I chlor 30 blinking lights

2182,

Nothing else will work if you a red flow light.. Period...

When the system checks for the salt level it will flash the red and green salt lights.. Without any flow, it cannot test the salt level.

Do you actually have water flow?

Can you feel a good strong flow out of your pool returns?

Do you have a VS pump? If so, at what speed is it running?

If this is a new pool, did it ever work right?

The cell could be installed backwards or the flow switch could be installed backwards..

Show us a couple of pics of your equipment pad, so we can see how things are plumbed..

Thanks,

Jim R.
 
There appears to be flow to the filter and pump. This issue just start yesterday, I took a water sample to pool store and they said everything was good.

2182,

The pics of the cell with green lights appears to show the cell working at 70% output.

The other pics appears to show low salt and low flow..

When did you take the pics with all green lights?

Does it just do the flashing lights for about 5 minutes when the pump first starts up or???

Thanks,

Jim R.
 
The pcs with green lights are from a couple months ago, the system was all good on Saturday. Error codes have been going off since 7am this morning.

Start by cleaning your filter. It is likely your filter clogged to where the flow is insufficient for the SWG.

Then do a Overnight Chlorine Loss Test and see if algae is clogging your filter. If so, you need to do the SLAM Process

Yes, I am sure your water is clear and algae can be in clear water.
