Accessories
Accessories only help if they fit the machine you have. The model name is on the base or the back, and that string is what you match.
For espresso, the common pieces are a water filter for the tank, a tamper, a milk jug, a knock box and cleaning tablets. A tamper has to match the basket diameter. A 58 mm tamper in a 54 mm basket does not fit, and the other way round leaves a ring of dry coffee that channels. The jug size follows how many drinks you steam, not how large a jug looks on a shelf. A litre jug for a single flat white gives you a lot of milk you cannot texture properly, because the tip never sits at the right depth.
Cleaning tablets for the group head and descaler for the boiler are different chemicals. Using one in place of the other does not complete the job the light is asking for. Replace the water filter on the interval in the manual, including when the coffee still tastes fine.
Jugs, bowls and lids for blenders and processors are model-specific. A lid from a similar-looking bowl often sits proud and leaks when the machine starts. Bring the model name into the email if you are asking about a replacement part.
The machines themselves are listed under coffee, blenders and food processors.
