Frequently Asked Questions

Why is my KitchenAid 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 KitchenAid 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.

My KitchenAid Kcm140 pump won't pull water — how to fix?

No-flow on a KitchenAid is usually one of three: the tank is not seated properly, air is trapped in the pump, or scale is blocking the inlet. Remove and refit the tank, run a rinse cycle, and descale if it persists. Full troubleshooting in our Water Not Pumping guide.

How do I prime the pump on a KitchenAid coffee machine?

A KitchenAid that runs but moves no water has a flow blockage or an air lock. Start with the tank seal and a blank brew to push air through, then check the inlet filter for scale. If flow is still zero, our Water Not Pumping guide covers pump and valve repairs.
