Coffee maker overflows the filter basket; coffee and grounds spill over.

Safety first: Unplug the unit and allow it to cool before cleaning.

• Reduce coffee amount: Use the recommended amount of coffee for your Tristar model and avoid very fine espresso grinds in drip machines.
• Clean filter holder: Remove the filter basket and holder. Clean the bottom outlet hole and any drip-stop mechanism thoroughly with warm soapy water and a small brush.
• Check drip-stop valve: Ensure the spring-loaded valve (if present) moves freely and is not stuck closed by dried coffee.
• Descale: Run a descaling cycle to normalize water flow and prevent surges that can cause overflow.

Note: Always use the correct size paper filter or the supplied permanent filter.
