After mastering the perfect steamed
Hello, my name is mike. I have been in the espresso business for 20 years, I don't think you have lot pressure, unless you have any water leaks in or around machine, assuming you don't, I believe it is simple as your froth steam wand is partially clogged and needs good cleaning. If it is partially clogged or dirty, YES it will appear as loss of pressure, as pressure will back up and not go through wand. Use small needle or opened up paper clip and stick in wand holes to make sure all holes are not clogged in addition read my story below and please let me know if this has solved problem.
Have you ever wondered, 'how do I descale my expresso machine?' First lets us understand what is exactly is scaling. The build up of minerals inside the hot parts of your coffee machine or espresso machine is commonly called lime scale. When lime scale builds up inside the Espresso machine, it slows down the water flow, reduces the boiler capacity and can prevent your coffee machine from working properly. To keep your Espresso machine operational at full order, it is important to descale it every three months. The time intervals between descaling depend upon many factors. Quality of your water and the amount of water running through the machine are the two main factors that decide the frequency at which you should descale your Espresso machine. The more you your machine, more often should you descale it. In some cities, in conjunction with a water filter you can use your coffee machine for a year or more without descaling at all. If you use less water by drinking espressos you'll need to descale less often than if you make cappuccinos.
Descaling products are widely available from stores that sell coffeemakers and espresso machines. Be sure that the product you buy to descale your Espresso machine is intended for this specific use only. Before you descale your Espresso machine, always unplug it and make sure that it is cold. Also, never immerse the appliance in water and nor should you use abrasive cleaning products or scouring materials on any part of your Expresso machine. In case your Espresso machine does not come with a instruction guide or booklet, then use a proper citric acid based descaling solution designed for espresso machines. This should be mixed and prepared as per the instructions on the bottle or packet. Once your Espresso machine has been descaled properly you would not be left wondering, 'how do I descale my expresso machine?', treat yourself to a great cup of coffee.
