Frequently Asked Questions

Why is my Mr. Coffee machine not pumping water?

A pump that spins but moves no water is either air-locked or its inlet is blocked. If no water comes out of your Mr. Coffee machine, the tank may be mis-seated, there may be air in the circuit, or the pump inlet is blocked by scale. Reseat the tank, run a blank cycle to purge air, and descale if flow stays weak. See our Water Not Pumping guide.
