How to Fix / Troubleshooting

Safety first: Unplug the coffee maker immediately and do not use it until the leak is resolved. Water inside an electrical appliance is a shock hazard.

External checks:

  • Reservoir inspection: Remove the water tank and check for cracks or a damaged outlet valve seal. Replace the reservoir if damaged.
  • Carafe and lid: Ensure the carafe is not cracked and that the lid is properly fitted.

Internal inspection:

  • Remove the base or side panel to inspect all silicone hoses and hose clamps.
  • Look for signs of water trails, mineral deposits, or corrosion to locate the leak source.
  • Tighten or replace hose clamps as needed. Replace any hose that is brittle, cracked, or swollen.
  • Inspect the boiler or heating block for cracks; if cracked, the entire assembly must be replaced.

Do not operate the machine with any known internal leak.
