If your steam wand is dripping from inside the tip on the Ascaso Dream steam tip, the first step is to descale the Ascaso Dream through the steam wand by following the instructions here.

If you are getting leakage from where the stem connected to the knob on one end and inserts into the steam valve on the other end, then you need to replace the 2 o-rings on the stem or you need to adjust the golden ring on the stem and set screw that holds it into place.

If your steam knob can be turned until the o-rings are exposed, then the set screw needs to be tightened or the golden ring that carries the set screw needs to be adjusted.

Set screw tightening

  • Stand the unit up. Rotate the steam knob inwards, and try to find the pinch on the stem to align with the whole in the golden ring. Insert the set screw and tighten it with an Allen key wrench.

Before proceeding to next step, turn steam knob and stem fully into the valve until it stops.
