When You Should Empty Water From A Bunn Coffee Maker

You should drain a Bunn coffee maker any time you are moving it from one location to another or shipping it for repair or to sell so that it doesn’t leak. However, you should also empty your brewer when you are putting it in storage for a while, or when you plan to not use it for an extended period of time for whatever reason.

Why It Is Important To Empty A Bunn Coffee Machine

The water used to brew your coffee contains minerals. The level of minerals in your water will be determined by where you live. Some areas have what is known as “hard water” which is higher in mineral content. While your Bunn coffee maker is not being used, if there is water left inside then these minerals cause limescale buildup in the machine’s internal parts. While not toxic, this can impact your coffee’s taste and temperature when you go to use the machine again. It can also negatively impact water flow which can cause your Bunn coffee maker to drip slow or not pump water at all.

If you don’t drain your coffee maker, you would have to clean and descale, possibly several times, to remove this buildup before you can use it again. In addition, if you are leaving your coffee maker behind in a cold climate, this water could also freeze and damage your machine. Taking a few minutes to empty it and prepare it for storage will save you some headache later.
