Cleaning and descaling are two different things. You need to do both to keep your coffee machine clean, efficient, and reliable.<\/p>\n\n\n\n
Cleaning removes coffee oils and gunk from spots like the portafilter and drip tray. <\/p>\n\n\n\n
Descaling is all about tackling those hidden mineral deposits inside the water system.<\/p>\n\n\n\n Why you need to know how to descale espresso machine? You might not always see limescale building up, but your espresso machine will usually give you a few warning signs before things get out of hand.<\/p>\n\n\n\n If your machine is suddenly taking forever to heat up or brew, that\u2019s a big red flag.Mineral buildup can slow everything down and mess with how your machine works.<\/p>\n\n\n\n You might also notice:<\/p>\n\n\n\n If you\u2019re seeing a few of these issues at the same time, there\u2019s a good chance limescale is already causing trouble inside your machine.<\/p>\n\n\n\n Descaling may also be necessary when your espresso suddenly tastes different despite using the same beans and recipe. You may also detect an unusual mineral or metallic taste in the cup.<\/p>\n\n\n\n If you\u2019ve already cleaned all the parts you can take out and things still aren\u2019t right, there\u2019s a good chance limescale inside the machine is to blame.<\/p>\n\n\n\n Every espresso machine is a little different, but the main steps are pretty much the same: get your machine ready, run the descaling solution through, rinse everything out really well, and then do a quick test before you make your next cup.<\/p>\n\n\n\n First things first, make sure your espresso machine is turned off and has cooled down if you just used it. Take out the portafilter, any leftover coffee grounds, and any other parts you usually remove when cleaning.<\/p>\n\n\n\n Go ahead and empty out the water reservoir and give it a quick rinse. If your machine has a water filter, take that out too. You don\u2019t want the descaling solution touching the filter since it can mess it up.<\/p>\n\n\n\n Mix up your descaling solution just like the instructions say (stick with the one the manufacturer recommends). Pour it into the reservoir with the right amount of water. You shouldn’t use a homemade mix unless your machine\u2019s manual says it\u2019s okay.<\/p>\n\n\n\n Set a big container under the group head and the steam or hot water spout to catch everything that comes out during the process.<\/p>\n\n\n\n If your machine has a descaling button or program, turn that on and follow whatever it tells you to do. This is usually the easiest and safest way since the machine handles the timing for you. <\/p>\n\n\n\n If you’re learning how to descale a Breville espresso machine or how to descale DeLonghi espresso machine, for example, check your specific model’s instructions before starting. The descaling process can vary between machines.<\/p>\n\n\n\n In case your machine doesn\u2019t have an automatic cycle, you\u2019ll need to run the descaling solution through the brew head and steam wand in a few rounds. Let the solution sit for a bit between each round so it can really break down any buildup inside.<\/p>\n\n\n\n Keep going until you\u2019ve run all the solution through, just like the instructions say. Don\u2019t rush this part, and definitely don\u2019t walk away if your manual says to stay close.<\/p>\n\n\n\n When you\u2019re done with the descaling cycle, dump out the container and take out the reservoir. Give the tank a really good rinse before you fill it back up with clean water.<\/p>\n\n\n\n Run clean water through the group head and hot-water\/steam outlet to flush out any remaining descaling solution. Depending on the machine and descaler instructions, you may need to refill the reservoir more than once.<\/p>\n\n\n\n Don\u2019t skip this step! If you don\u2019t rinse well enough, you\u2019ll end up with weird-tasting coffee next time, and nobody wants that.<\/p>\n\n\n\n Once you\u2019ve rinsed everything, pop the water filter back in if you use one and double-check that all the parts are in the right place. Run plain water through the group head one more time and toss it out.<\/p>\n\n\n\n Now it\u2019s time for a test shot. Make sure the water flows like normal, the machine heats up properly, and there\u2019s no strange taste or smell.<\/p>\n\n\n\n If you\u2019re still seeing a descaling warning or something seems off, check your manual before you start the whole process over again.<\/p>\n\n\n\n Descaling steps depend on how your espresso machine heats and moves water.<\/p>\n\n\n\n Semi-automatic espresso machines generally require a hands-on descaling process. Use the manufacturer-approved descaling solution and follow the instructions for your specific model.<\/p>\n\n\n\n Depending on the machine, the solution may need to pass through the brew circuit, hot-water outlet, and steam wand. Some models also require pauses or soaking periods between stages to allow the solution to dissolve mineral buildup.<\/p>\n\n\n\n For example, how to descale Breville espresso machine varies by model, so consult the appropriate user manual. If your machine uses a thermoblock rather than a traditional boiler, follow the manufacturer\u2019s recommended descaling procedure for that specific model.<\/p>\n\n\n\n Fully automatic machines usually have a built-in descaling program. The machine controls the process, so maintenance is simpler.<\/p>\n\n\n\n HX machines have one steam boiler and a separate heat-exchange system for brewing water. Since the water pathways are connected, descaling needs extra care compared to simpler machines.<\/p>\n\n\n\n Always follow the manufacturer’s instructions. If there is a lot of scale, it is safer to have the machine serviced by a professional instead of trying to descale it yourself.<\/p>\n\n\n\n Dual boiler machines have one boiler for brewing and another for steam. Descaling can be more complex. Some models are not made for user descaling.<\/p>\n\n\n\n If the manual says to get professional maintenance, follow that advice instead of using a general descaling method.<\/p>\n\n\n\n >>> Read more: How to Clean a Coffee Grinder: Keep Every Cup Tasting Fresh<\/a><\/em><\/p>\n\n\n\n Here are some general guidelines:<\/p>\n\n\n\n Pay attention to how your machine is working. Changes in performance can be a sign that it is time to descale.<\/p>\n\n\n\n You may notice these signs before your next scheduled descaling. If your coffee tastes different or the machine is not working as usual, check for limescale instead of waiting for your regular maintenance date.<\/p>\n\n\n\n The safest approach on how to descale espresso machine is to check your espresso machine’s manual first and use a solution approved for that model.<\/p>\n\n\n\n![\"how](\"https:\/\/airtalkwireless.com\/blog\/wp-content\/uploads\/2026\/08\/how-to-descale-espresso-machine.jpg\")
