I was cleaning strainers today after an invasion of moon jellies and I shut the seacock to the AC pump with the salon AC still on. It shut down at some point while I was cleaning the strainer and now it just shows code HP blinking on the screen. They are SMXHT screens. I see that fault Code in other posts on the web but the not for the SMXHT. When I turn it on to heat or cool I hear a quick click like a solenoid and then it goes right to the HP code. I can’t get it to do a factory reset by holding the power and mode buttons.
The pump is primed because it feeds the other 2 interior ACs and those are flowing water fine. I tried running street hose water pressure through it but didn’t change anything.
What is the next thing to check?
