I've run into high stabilizer this year from overdoing pucks.
I do have liquid chlorine but it is hard on the bottom of my liner pool.
My last pool guy didn't hook up the main drain to my pump (pipe still there) and all chlorine easily makes it to the deep end bleaching the liner.
How do I do this ?
Verify power at MV on P-4 Terminal on digital circuit board.
Verify Power to valve MV voltage (Replace Valve).
From another troubleshooting guide.
I have a voltmeter. I guess I just dont know where the MV-MV/PV terminals are.
