If your steam wand is dripping from inside the tip of 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 connects 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 the set screw that holds it in 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 hole in the golden ring. Insert the set screw and tighten it with an Allen key wrench.

Steam valve adjustment and o-ring replacement – for Ascaso espresso machines with a steam knob

  1. Turn off the power switch, coffee switch, and steam switch. Unplug the electrical cord from the electrical outlet and let the unit cool if it is still hot.
  2. Remove the top cover. Two long screws behind the grouphead need to be removed. The cover slides upwards.
  3. Loosen the small screw on the stop ring.
  4. Turn the steam knob outwards and inwards to make sure there is clear motion back and forth. If replacing the o-rings, remove steam completely and change the o-rings. If clear motion does not exist or there is excessive rubbing on the body/inner wall, the valve position on the boiler may need to be adjusted. Before proceeding to the next step, turn the steam knob and stem fully into the valve until it stops.
  5. Make sure water is in the reservoir and insert it into the machine.
  6. Place a large cup under the grouphead without the portafilter and one large cup under the steam.
  7. Turn the coffee switch on, plug the electrical cord into the electrical outlet, and then turn the power on. Be careful not to touch anything inside the machine to avoid personal injury or damage.
  8. Water will start to flow from the grouphead into the cup. Turn out steam knob UNTIL a steady stream of hot water flows from the steam wand and stops from the grouphead.
  9. Leaving the steam knob in the exact position, turn the power off and unplug the electrical cord from the electrical outlet.
  10. Position the stop ring on the steam valve stem against the inner wall and tighten the small screw.
  11. Place the top cover back on and tighten the screws into the extenders. Please note that sometimes extenders loosen when screws are removed.
