  • Prevents clogs and blockages in the machine
  • Ensures consistent brewing temperature
  • Increases the lifespan of the machine

Bunn recommends cleaning the coffee maker every three months. However, it may be necessary to clean it more often, depending on the frequency of use, water quality, and the type of coffee beans used.

If you ignore these signals, the machine will continue to deteriorate, and you may have to replace it sooner than expected. Therefore, it’s wise to clean it regularly to keep it in top condition.

Regular cleaning of your bunn coffee maker will not only ensure the quality of every cup and increase the machine’s lifespan but also prevent inconvenient break-downs. Cleaning may seem like a burden, but it’s a small price to pay for the privilege of enjoying delicious coffee every day.
