Question about Rheem 266K to 399K BTU Swimming Pool Natural Gas Heater ()
Kind of a cascading problem as we open our pool here in the sunny (!) pacific northwest!
24 ft round above ground plumbed with main drain
1 hp brand new pentair whisperflow (may be defective?)
Large sand filter, backwashed
green algae in pool
pool return froze last winter, just rebuilt
Rheem heater is 4yrs old, did not use it last year
OK: Pool pump died last fall and we bought a new one but didn't install it. Thought the lines were drained, but apparently one was not. But it is fixed now.
Just got the new pump inline and are working to raise TA and kill the algae so we can add sanitizer.
The pump ran for about 2 hours, smelled a little hot (new equipment?) then shut off. Pressure is at about 10, so that's not a problem.
Heater is throwing error code CFH Check Filter Strainer.
Pump was off for quite awhile, maybe some part of the heater is calcified/blocked? Maybe new pool pump is defective? Whaddya think?
Trying to get the TA correct before you kill the alge? Leslies diagnosis?
You probally just need to kill the alge before you do anything. Nevermind the TA for now and just add about ten gallons of liquid chlorine. The alge untill you kill it will plug the filter constantly. This will give you the code on the heater and will make the pump run very hot and will hurt the plumbing by shrinking it. This will stop water flo by letting air in also it will leak water at the pump discharge.
A lot of liquid will break the alge as it is unstable, but use a lot.Once you kill the most of the alge then add probally another four gallons and now brugh the whole thing real good. now you can start running again and start with all the stuff they will sell you to adjust the PH and TA. I hope this helps, and good luck.
