Wet steam would be more likely from a high water level in the boiler than not hot enough. Any machine though will give you some water in the steam until the steam system heats up and even then you might get some, remember, water is steam and steam is water, even the driest steam can condense on the walls of a glass vessel.

I have a new problem.  Today, while testing the machine, the water level probe shot up on it's own twice within an hour.   It popped up about an inch causing the autofill to kick in each time. Also I noticed that the probe easily pulls out of the nut and it comes out without the white teflon sheathing attached.  I tightened that probe nut but the probe can still be easily pulled out.  Is that normal?  Can it be tightened?

Sounds like the nylon or teflon ferrule has hardened & become too brittle to grip the water level probe tightly enough to prevent it from sliding up under boiler pressure.

You should take it apart to inspect it to find out. A temporary fix (may work pemanently) I'm thinking of would be to angle/overlap wrap a single layer (or maybe two) of plumbers white teflon tape over the contact area of the ss probe where it meets the internal ferrule, & see if that works.
The slightly fatter built up diameter of the probe maybe enough to push out against the ferrule & make it tight enough to work without the nut running out of tightening adjustment room.

I got the bottom nut off using an 18mm box wrench but now I am confused as I don't think the sleeve is normally suppose to come out when you remove the probe as it is "screwed" into the bottom nut.  I had to unscrew the sleeve to get it out.  I will try reinserting the probe now after slightly compressing the sleeve with a pair of pliers to see if that will hold the probe in better.

That ferrule has been deformed/squashed by tightening & has in effect deformed into the internal threads of the nuts body. By overtightening & then loosening the whole tube & ferrule has self formed some threads there that I can see, but it shouldn't matter.

Do you have any teflon tape to wrap on the ferrule?

Hi Craig - No I don't have any teflon tape but I just put everything back together and the probe is very snug now and hopefully I won't have any trouble with it but I have the top off of the Oscar and will be monitoring it for awhile to see if any leaks develop or if the probe pops up again.  Since installing my new element I have noticed that the steam is a tiny bit wet compared to before so I have increased the pressure by turning my Parker P-Stat 1 & 1/2 turns towards the "+" sign to see if that alleviates the wet steam.

Thanks Erik, You could try dropping the boiler level a tad by lowering the probe to help alleviate the wet steam., that is unless it's already bottomed out. Hope that it works out & stays that way for you. {;-)

Sounds to me like the ferrule (because of the formed threads on it) wasn't completely bottoming into the 45 degree angle on the fitting, preventing it from being compressed properly on the probe.
