Plastic water reservoir develops cracks or leaks.

Safety: Do not operate the machine with a leaking reservoir; water can reach live electrical parts.

• Inspect reservoir: Remove the reservoir and examine it under good light for hairline cracks, especially near the base and seams.
• Avoid temporary fixes: Do not rely on glue or tape repairs; they are unsafe for hot water and food contact.
• Replace reservoir: Order a genuine Moccamaster replacement reservoir compatible with your model and install it according to the manual.
• Use proper cleaners: In future, avoid abrasive or solvent-based cleaners that can weaken plastic.
