Working on my machine and one of the group head three way solenoid valve body has a hole in it (see image below) and I am not sure if this makes it un-servicable?
This group did not work when I got the machine, but I am 99% sure that is electrical.
I (sort of) know how the solenoid works with this valve, but am unsure if this part with the hole is supposed to be water tight?
The other group head is fine, but they are different as in one or the other has been replaced over history.
I can get a new part but if this hole is common in some units Id prefer to save the money.
Any thoughts on if this hole is a locating mechanism for a solenoid, or do I need to replace it?
Thanks as always for your consideration. Cheers, Colin
