Clean the Shower Screen and Group Head
Over time, coffee oils and residues can clog the shower screen, restricting water flow and pressure. Remove the shower screen according to your machine’s manual and soak it in hot water with a cleaning tablet. Use a soft brush to clean thoroughly before reassembling.
Check Water Filter and Water Quality
If your machine has a charcoal filter, ensure it’s not clogged or expired. Replace the filter if necessary, following the manufacturer’s instructions. Using filtered water also helps prevent mineral buildup that can cause pressure issues.
Perform a Descale and Flush
- Follow your Breville Bambino Plus’s descaling instructions, using a recommended descaling solution.
- Run a water cycle without coffee to clear out any mineral deposits.
- Repeat if necessary, especially if you notice scale buildup or reduced flow.
Test and Reset the Machine
After cleaning, reassemble your machine and run a test shot. If the pressure remains low, turn off the machine, unplug, and wait a few minutes before turning it back on to reset the system.
