Hi! My yard guy decided to unplug my pool and failed to plug it back in. We were away for the weekend and it has also been storming here so I just noticed today. I plugged it back in and it kicked on but started giving me a code 90. I've backwashed, rinsed, cleaned skimmer, then detached skimmer, cleaned sensors, checked for clogs, checked for air bubbles, etc. The pressure is great and the flow is very strong. I am not sure what else to do. Why would I still be getting a code 90?

Hi. I have not had that issue thankfully so cannot offer any experienced advice. However, this should help get you started until an expert can chime in.

Hi welcome to TFP. Please take a moment to fill in your signature with your equipment as it will be easier to assess what you have.
Code 90 is a SWG issue. Check for air in the lines, flow valve, and inspect the plates. Might want to tip the units a little to see if a bubble is trapped in the flow valve.
