Espresso Machine Descaling Calculator
Most people descale on a fixed schedule and ignore whether their water is hard or how often they actually pull shots. That matters. Hard water can demand descaling twice as often as soft water. Heavy daily use accelerates scale buildup faster than manufacturers’ one-size averages account for. Pick your machine, tell me your water and usage, and I’ll give you a schedule based on your specific situation rather than a manufacturer default that assumes conditions you may not have.

With medium-hardness tap water and moderate daily use, the Breville Bambino Plus sits close to the typical manufacturer baseline for scale accumulation.

How Often Should You Descale an Espresso Machine?
The honest answer: it depends on three things. First, your machine. Super-automatics with built-in water filters like the Philips LatteGo with AquaClean can go significantly longer between descales than a simple thermoblock machine. Second, your water. A household with hard tap water will see scale build up twice as fast as one running softened or filtered water. Third, how much you use it. A machine pulling six shots a day accumulates scale far faster than one pulling two.
A common general rule is every two to three months, and that’s a reasonable starting point for medium water and average daily use. But it breaks down at the extremes. If you live somewhere with genuinely hard water and make four or more cups a day, waiting three months between descales risks heating element damage. If you have a reverse-osmosis system and only pull one shot a day, you could safely stretch to six months or longer.
The question of how often to descale a Breville espresso machine comes up often because Breville is the most common mid-range machine in home kitchens. Breville recommends every two to three months under normal conditions. Our Breville descaling guide walks through the full process step by step for every current Breville model. For other machines, the general descaling guide covers the process and which solutions to use.
One note: if your machine has a built-in descale indicator, use that as your primary signal and treat the calculator above as a cross-check. Built-in sensors that measure water volume or cycle count are more precise than any rule-of-thumb schedule.
