Buying Guide: Replacement Parts for Automatic Machines
Keep these points in mind before you buy.
Match the model and part number
Find the model on the label under the drip tray or on the back, then match the exact part number. Many parts look alike but differ by a few millimeters.
Genuine vs. compatible parts
Genuine parts guarantee fit and keep any warranty simple. Compatible parts cost less; check recent reviews for fit.
Change water filters on time
Most machine filters last about 2–3 months or a set number of liters. Register the filter in the menu so the machine reminds you.
Signs a seal is worn
Leaks around the portafilter or brew unit, weak pressure or water under the machine often mean a gasket or O-ring is flat or cracked.
Hard water and scale
Minerals in hard water form scale that clogs heaters and lines. EPA lists scaling as a common nuisance effect of mineral-rich water.
Use food-safe grease
When replacing O-rings or servicing a brew unit, use a thin layer of food-safe silicone grease. Never use petroleum grease.
Parts That Wear First
Check these every few months:
- Water filter: every 2–3 months.
- Brew unit O-rings: yearly.
- Milk tubes: monthly clean.
- Drip tray grille: when bent.
