Coffee maker leaks water from the bottom during or after brewing.

Safety first: Unplug the coffee maker immediately and do not use it until the leak is resolved. Water and electricity are a dangerous combination.

External checks:

• Inspect the water reservoir for cracks or damage; fill it and watch for drips.
• Check the reservoir-to-machine connection seal for wear or deformation.

Internal inspection (advanced):

• Remove the bottom cover to inspect the silicone hoses, clamps, and heater connections.
• Look for mineral trails or wet spots indicating the leak source.
• Tighten or replace hose clamps and any cracked hoses.

If the heater tube or boiler itself is leaking, the heater assembly must be replaced. This is typically a complex repair; consider professional service.
