Ok, so I scheduled an appointment with a Leslies pool tech to come out today since they are right behind my house and here's what followed. Bare in mind, not one word is exaggerated.
He knocks on the door and I introduce myself and show him around to the back where the equipment is. I prefaced that I just started taking a look at the heater and explained what I did thus far. I told him I am getting an AO code, indicating the blower and I pulled the top and had 2 heat cracked hoses and the blower vacuum hose wasnt even connected. After trimming them, I reconnected them and I could suck on the tube to temporarily make the AO code go away. I told him I hadn't checked the resistance on the wires yet and although the blower spins freely by hand, the blower doesn't kick on either way. I did check the power and all the hot wires are providing power.
Joe asked that I turn the system on so I clicked it on. He kneeled down and pressed the system button to cycle through standby/spa/pool and then took a look at my PSI reading. He said that's your problem right there, you need to clean your filters. In my head, I was thinking this couldnt possibly be the cause, but he's the expert so I actually asked him flat out and he said again, I 100% guarantee that's the problem. He said, I just saved you $100 bucks and you will be swimming in there tonight. He said, pop the cartridge top off and pull the filters to let the water flow through and the heater will kick right on because it's a safety feature.
I told him if that was true than that is the best news I've heard all day and told him it would take me 5 minutes to pop the top and pull the filters. He said, sorry guy but I don't have time to hang out, but again that's the issue. His exact words were, "your up and down buttons work so everything is working fine." He then packed up, shook my hand and split. No joke this was less than 8 minutes total.
So as expected, I pulled everything and within 45 minutes with my power washer, I had those filters bright white again. I popped them in and with the spa return and suction closed, the PSI reading is at maybe 3. I then close the pool suction and the PSI is about the same, then when I close the pool return over to SPA the PSI goes to about 18. I don't know if that's normal or not, but either way I thought I'd share the events of the last 90 minutes.
End result is the AO code persists to both SPA and POOL. Did this Leslies tech have a hidden camera and was just messing with me??
