help1. Understand the Problem

Over time, mineral deposits and coffee oils can block the narrow water passages inside a drip coffee maker. This prevents water from moving from the reservoir to the heating element and up through the showerhead. The result is a machine that sounds like it's working but produces only a few drops or nothing at all. This guide shows how to clean the most common blockage point safely.

Frequently Asked Questions

Can I use a needle instead of a paperclip?expand_more
Yes, but a paperclip is safer because it's less likely to scratch or widen the opening. A thin sewing needle works if used carefully.
Why is my coffee maker making noise but not pumping water?expand_more
The pump is likely trying to push water past a blockage. Clearing the check valve usually solves the issue.
How often should I clean the one-way valve?expand_more
Inspect it every 3–6 months, especially if you have hard water. Regular descaling also helps prevent clogs.
