How to Fix / Troubleshooting

Safety first: Allow the unit to cool before descaling or removing parts. Unplug during cleaning.

  • 1. Perform intensive descaling
    • Fill the reservoir with a 1:1 vinegar and water solution.
    • Run a brew cycle until halfway, then pause for 20–30 minutes to soak.
    • Resume and complete the cycle, then repeat if flow is still slow.
    • Finish with 2–3 clean water cycles.
  • 2. Clean inlet and spray head
    • Remove the water reservoir and clean the outlet screen with a soft brush.
    • Open the filter basket and remove the spray head (if removable) to clear any coffee oils or mineral deposits.
  • 3. Check water filter
    • If your model uses a charcoal filter, replace it if it is older than 2 months or visibly dirty.
  • 4. Pump assessment (advanced)
    • If descaling and cleaning do not restore normal speed, the pump may be worn.
    • Unplug, remove the bottom cover, and inspect the pump and hoses for kinks or restrictions.
  • 5. Replace pump if needed
    • Install a new Sunbeam-compatible vibration pump if the existing one is weak or noisy.
