Hi Geoff, sounds like the hose from the bottom of the matrix to the sump is partially blocked causing an overflow at the float/rocker. A sure way to tell if it’s getting blocked is to listen to the water when it drops out of the matrix (3 fills), you should hear it flowing like a small waterfall. If it goes very quiet then it’s on the point of overflowing.
You might also want to check the free operation of the float and that there isn’t any real amount of corrosion on the microswitch arm 😉
