Learn what to do if your Rancilio Silvia is producing too much steam or appears to be boiling your milk.
Too Much Steam/Milk Boiling
If you think your wand is producing too much steam, or your milk looks like it is boiling, then you may need to make an adjustment to your frothing technique. Boiling milk, or milk that is getting too hot before frothing is completed is an indication that incorrect frothing technique is being used. Review the "Frothing Habits to Avoid" section of this machine's "Froth and Steam Better" article that addresses frothing difficulties for more information.
If you have tried adjusting your technique and the wand still appears to be producing too much steam, then a steam test should be completed. Instructions on how to conduct a steam test can be found in the "ALL_MODELS_Steam_Test" document attached at the end of this article.
If the machine is within the specified steam test range, then the machine is producing the correct amount of steam and an adjustment to frothing technique is necessary. Using a carafe that is chilled in a freezer before frothing is helpful for keeping the milk cooler for longer, allowing for more time to froth before the milk begins to scald.
