Step 2: Clean the Portafilter and Basket

  1. Remove the portafilter from the machine.
  2. Disassemble and wash the filter basket and portafilter thoroughly with warm water and a brush.
  3. Check for any coffee grounds or oils blocking the holes.
Cleaning ensures proper water flow and pressure buildup.

Step 3: Descale the Machine

Scale buildup can restrict water flow and cause pressure issues. Use descaling tablets designed for Breville machines, such as the Breville BEC250 or the replacement tablets B0FCBPBBL4, following the product instructions. Run a descaling cycle to remove mineral deposits from internal components.

Step 4: Check and Replace Water Filters

If your machine uses charcoal filters (like the Breville Charcoal Filters B000VX44OO), replace them regularly—every 2 months is recommended. Dirty filters can reduce water flow and pressure. Remove the old filter and insert a new one, following the user manual guidelines.

Step 5: Inspect and Replace Seals or Valves

If pressure issues persist, check the seals and valves for wear or damage. Worn-out seals can cause pressure leaks. Consult your user manual for specific parts to inspect or replace, or contact a professional if needed.
