cheers Ecka.

Easy to replace, BUT I would look very carefully for traces of metallic particles in the well under the solenoid plunger. ANY trace of sparkly bits shows the hardfacing is coming off the cam plate, and this alone will / can hold the plunger up off its seat slightly, causing the symptom of no shut off. Of course the solenoids DO fail, and the plunger spring can break etc but check carefully for these metallic bits while you have the solenoid out.
The pump will require an overhaul should metallic bits be visible.
