Coffee maker leaks water from under the machine during or after brewing.

Safety first: Unplug the coffee maker immediately. Water and electricity are a dangerous combination.

• Identify source: Remove the reservoir and inspect it for cracks, especially around the outlet. Fill it over a sink and check for drips.
• Check external seals: Inspect the reservoir seating area and any visible gaskets for damage or debris preventing a proper seal.
• Dry the area: Wipe up all water around and under the unit. Do not operate the coffee maker while it is wet.
• Test with small amount of water: Refill the reservoir halfway, reseat it, and observe the unit (unplugged) for any passive leaks before plugging it in.
• If water appears from inside the housing: An internal hose, clamp, or the heating block itself is leaking. Do not use the unit; contact a qualified technician for internal inspection and repair.
