im getting first water and eventually wet steam from the arm; is this a problem with the fill probe in the steam boiler

how do i fix; if its the probe, how do i access

Water always comes out before steam. Does it last longer than 1 or 2 seconds? Does water come out the second time you open the wand as well?

this is much too much water; not a burst but a steady stream

Sometimes the fill probe nut loosens, causing the sensor to move up. GIve this old post a read:

You are not using mineral free water...are you?

so it seems my fill probe had risen up; pushed down the probe, tightened up the nut, got out the excess water and it seems to be working normally; surprising how such a small change in the height of the fill probe could case so much water to come out of the boiler and the boiler to fill so often

Good to hear that fixed it, and no new parts were needed.

Keep in mind, there is not much headspace in the steam boiler.If the probe loosens and moves up, the water has no place to go but out the wand, and the slightest loss of water will trigger the pump to refill.

thanks; had never realized this part of machine was so fine tuned

Thanks for posting your repair tip about the water level probe - this helped me fix my S2 this morning!
