Vivaldi II - Steam wand barely working

Post by doppiomichael »

Boiler seems to be working fine as it can produce hot water. The steam wand takes a long time to get going (10-15 seconds) and then barely lets out enough steam to warm a very small amount of milk (3-4 oz). I removed and cleaned the tip, but still no luck.
What am I missing? Thank you!

Before getting deep into it, check these things out:

1) With the boiler completely cold, confirm that the boiler pressure gauge is exactly at 0 bar.
2) Let the steam boiler get completely up to temperature, check the boiler pressure gauge.

Finally got to test this. We mostly drink Americanos so I wasn't freaking out too much.
So, when the boiler cooled down completely, the pressure did not go down to zero, it stopped at around 0.2. Then when I fired it back up, it stopped at 1.5 bar. Houston, we have a problem....
Thank you Chas!

Your gauge is a little off but not enough to justify its replacement. Your current 0 point is 0.2bar so a gauge reading of 1.5bar is really 1.3bar which is perfect for an S1 steam boiler.

The next thing you should check is that your water level probe has not gotten pushed up by the pressure. If so, this will reduce the space for steam.

Water level probe bolt was not loose. I tightened it down and was able to move it a tiny bit, but there isn't much steam coming out of the wand.
