How to Fix / Troubleshooting
Safety first: Unplug the coffee maker immediately if you see water leaking from the base. Water and electricity are a shock hazard.
- Dry the area: Mop up any spilled water around the appliance and on the counter.
- Check reservoir and carafe: Confirm the leak is not from an overfilled reservoir or a cracked carafe. Fill the reservoir and let it sit on the counter to see if it drips.
- Inspect external seals: Look at the reservoir outlet valve and gasket for cracks or deformation. Replace the reservoir if it leaks when removed from the machine.
- Do not continue using with internal leaks: If water appears from vents or the underside only when brewing, an internal hose or fitting is likely compromised.
- Professional repair required: Internal hoses, clamps, and manifolds must be accessed by opening the housing. Have a technician locate and replace the leaking component.
