Water in the stream line is normal especially just after First heat up and during any time gap in steaming. It’s just condensate or residual steam reverting back to water.

I’ve done some mods to my tray so I can blast steam in there without issue, but, I always have a small beaker half full of water and purge it for 10 seconds of so on every use and after as well. Becomes second nature. Can’t remember if you’re pro plumbing or not but the plumbed tray to me is just as convenient as plumbing the machine in. I will leave it at that before I get a here we go again😎
@DavecUK may be worth mentioning to the factory if they are sending them all out with plumbed as factory spec.
Mine was set to plumbed as well but I was plumbing it. Can’t imagine @Cuprajake changes that setting. It did have the plug in the solenoid so would never have actually known other than solenoid would have been energised during every empty tank. Cant imagine it causing anyone an issue if plug is fitted though.
