Frequently Asked Questions

What does the flashing error code on my Ninja machine mean?

A flashing code is the machine's way of naming the fault — the code itself tells you which module to check. Error codes on Ninja machines usually point to a specific condition: a full drip tray, an empty water tank, a stuck brew unit, or scale buildup. The most common codes are listed in our Error Code Flashing guide — most are cleared by a power reset or a descaling cycle.

My Ninja Ninja Hot And Cold shows an error code — how do I fix it?

A code on the Ninja display is the machine naming its own fault. Start with the easiest fixes: reseat the tank, empty the drip tray, and power-cycle the machine. If the code returns, our Error Code Flashing guide lists the codes and their fixes.

How do I clear an error code on a Ninja coffee machine?
