What does the limited one-year warranty cover?

The warranty covers defects in materials or workmanship under normal home use for one year from the date of purchase. Keurig will repair or replace a defective brewer without charge upon receipt of proof of purchase. Only the use of Keurig K-Cup brand pods and accessories guarantees proper functioning, and damage from non-Keurig products may not be covered by the warranty. (Page 5)
