    MM1 with the SEHP set up will not move left or right, the motor runs when requested to, the coils are magnetized when requested the cartridge valves are opening when requested, up is fine, down seems to be a little slow. Everything was working fine prior to losing left and right functions. What is it.

    I am going to swap out the s2 cartridge with a known good, the only other component that could cause these two symptoms is the poppet valve, anyone ever had a problem with that?

    Swap the S2 valve since you have one but you'll likely be digging into the poppet in then end, as yes they do have issues now and then and normally after a hard hit or too much water for too long in the system.

    poppet

    What am I looking at in the poppet? Can it be cleaned up or is replacement the way to go?

    They're around $25 so we'll just replace it if it's not the s2.

    I'd pull it apart and check it first, if necessary. If it has damage you'll see it.

    poppet

    You're right (as usual) Mike, broken spring on poppet valve, first time I've seen a poppet problem, do you think this guy hit something hard and that's what caused the spring to break? Of course he said he didn't hit anything.

    One good hard hit or multiple "normal" hits just over years of use will eventually take one out. So it's a tough call if you're looking for evidence. :D
