Hi,

We have a 2695 and got plunger homing error 0, we replaced the F1 fuse, bought a gently used torpedo, and the system reinitialized. 3 on-off cycles later, we got the plunger homing error 0 again. We connected our old torpedo, not in the flow path, and the system came back online. We then reconnected the torpedo that was connected to the fluidics, and the system initialized. So... is this a pump driver board gremlin that we most likely can solve by getting a new pump driver board?

Thanks

Either that or a really clogged in-line frit that needs to be replaced (the SS housing just above the purge valve contains this frit).
