Frequently Asked Questions

Why does my Keurig keep saying 'Add Water' when the tank is full?

This is a common issue with Keurig machines. The water level sensor may be dirty or misaligned. Clean the tank and sensor probes with a soft cloth. On some models, the reservoir may not be seated correctly.

Can I use ground coffee instead of K-Cups?

Yes, with the Keurig My K-Cup Universal Reusable Coffee Filter. It works with all Keurig machines and allows you to brew your own ground coffee.

Why is my Keurig brewing slow?

Mineral deposits can clog the water lines and needles. Descale your machine every 3-6 months using Keurig-approved solution. Also check the exit needle for blockages.

What causes Keurig to overflow?

Overfilling the reservoir, using the wrong cup size, or a clogged needle can cause overflow. Ensure the K-Cup is properly seated and the machine is clean.

How do I reset my Keurig after descaling?

After descaling, run several water-only brew cycles without a K-Cup to rinse the system. Some models require a manual reset; consult your specific model's manual.
