Introduction
A Bunn coffee maker is built for speed, durability, and consistent performance, whether you own a compact home model or a larger pour-over brewer. Because these machines heat water quickly and hold an internal reservoir, they require more attention than a standard drip coffee maker when they are not in use. Knowing how to store a Bunn coffee maker correctly can protect the heating element, prevent mold and mineral buildup, and extend the life of the appliance for years.
Many owners only think about storage when they are going on vacation, moving to a new home, or closing a seasonal property. Others need to store the machine during a kitchen renovation or while they temporarily switch to a different brewing method. Whatever the reason, improper storage is one of the most common causes of unpleasant odors, scale accumulation, and mechanical issues in Bunn brewers.
This guide walks you through every step of how to store a Bunn coffee maker, from pre-storage cleaning to choosing the right location and preparing the machine for future use. You will also find practical tips, a comparison of short-term and long-term storage, common mistakes to avoid, and answers to frequently asked questions. By the end, you will have a clear, easy-to-follow plan for keeping your Bunn coffee maker safe until you are ready to brew again.

Why Proper Storage Matters for Your Bunn Coffee Maker
Bunn coffee makers differ from many other brewers because they keep a reservoir of hot water ready at all times. This design allows for fast brewing, but it also means the interior stays warm and moist after each use. If you store the machine without draining and cleaning it, that moisture becomes a breeding ground for mold, mildew, and bacteria.
Mineral deposits are another concern. Tap water contains calcium and magnesium, which can leave scale inside the heating tank and tubing. When water sits in the machine for weeks or months, those deposits harden and become more difficult to remove later. Proper storage removes the water and gives you an opportunity to descale before the minerals set in.
Electrical safety matters as well. Storing a coffee maker that is still plugged in, or wrapping the cord tightly around a warm appliance, can damage the wiring and create a fire hazard. A clean, dry, and unplugged machine is far safer to store in a closet, basement, or garage.
Finally, proper storage preserves the taste of your coffee. Residual oils and old water can leave stale flavors inside the brew funnel and sprayhead. When you finally plug the machine back in, you want the first pot to taste fresh, not musty. Learning how to store a Bunn coffee maker the right way ensures that your next cup is just as good as the last one.
When Should You Store a Bunn Coffee Maker?
Not every period of non-use requires full storage. If you are only skipping a day or two of brewing, a simple rinse and wipe-down is usually enough. However, there are several situations where complete storage is the better choice.
Extended travel is the most common reason. If you are leaving home for a vacation, business trip, or family visit lasting more than a week, you should drain the reservoir and clean the machine before you go. This prevents water from stagnating while you are away.
Moving to a new house is another good time to store the brewer properly. Coffee makers should never be transported with water inside, as sloshing can damage internal components and create leaks. Emptying and drying the machine before a move protects both the appliance and your belongings.
Seasonal properties, such as lake cabins or mountain homes, often sit unused for months. If your Bunn coffee maker stays at one of these locations, it should be fully cleaned and stored before the off-season begins. Similarly, kitchen remodeling projects can expose appliances to dust, paint fumes, and physical damage, making temporary storage a smart precaution.
Pre-Storage Cleaning: The Most Important Step
Cleaning before storage is not optional. It is the single most important part of how to store a Bunn coffee maker. Skipping this step almost guarantees unpleasant smells, mold growth, or mineral buildup by the time you are ready to use the machine again.
Emptying the Water Reservoir
Start by unplugging the coffee maker and allowing it to cool completely. Bunn machines keep water hot inside the tank, so give it at least 30 to 60 minutes after the last brew cycle. Once cool, pour out all remaining water from the reservoir. Do not leave even a small amount behind, as standing water can become stale and support bacterial growth.
Cleaning the Sprayhead and Brew Funnel
Remove the sprayhead and brew funnel if your model allows it. Wash these parts with warm, mild dish soap and a soft sponge. Pay close attention to the sprayhead holes, where coffee residue and mineral deposits often collect. A soft toothbrush can help clear clogged holes without damaging the metal. Rinse thoroughly and set the parts aside to dry.
Descaling Before Storage
If you live in an area with hard water, descaling before storage is highly recommended. Use a descaling solution or a mixture of white vinegar and water, following your model’s manual. Run the solution through the brewer, then rinse with several cycles of fresh water. Descaling removes scale that could harden during months of disuse, making future cleaning much easier.
Wiping the Exterior and Warming Plate
Wipe the outside of the machine with a damp cloth and mild cleaner. Do not forget the warming plate, where drips and spills can burn onto the surface over time. A clean exterior prevents dust and grime from settling into crevices while the machine is stored.
Drying the Machine Completely
Moisture is the enemy of storage. After cleaning, leave the lid, reservoir, and removable parts out to air dry completely. You can use a clean towel to speed up the process, but make sure no damp areas remain before you cover or box the machine. Storing a damp coffee maker is one of the fastest ways to invite mold and mildew.
Step-by-Step: How to Store a Bunn Coffee Maker?
Follow these steps in order to prepare your Bunn coffee maker for safe storage. Each step builds on the previous one, so avoid skipping ahead.
- Unplug the machine and let it cool. Safety comes first. Disconnect the power cord and wait until the internal tank and warming plate are no longer warm to the touch.
- Empty all water from the reservoir. Pour out every drop. Tilt the machine gently if needed to remove water trapped in internal channels, but do not shake it violently.
- Remove all detachable parts. Take out the brew funnel, sprayhead, carafe lid, and any other removable components. These pieces trap moisture and coffee oils if left inside.
- Wash removable parts with warm soapy water. Use a non-abrasive sponge. Rinse well and allow them to air dry on a clean dish rack.
- Wipe down the exterior and warming plate. Remove splashes, stains, and dust. A clean machine is less likely to attract pests or develop odors in storage.
- Descale if necessary. If you have not descaled recently, do so now using a product approved for Bunn brewers. Rinse thoroughly afterward so no cleaning solution remains inside.
- Let every part dry completely. Leave components on a towel for several hours, or overnight if possible. Confirm that no moisture remains inside the reservoir or tubing.
- Reassemble or store parts separately. You can place dry removable parts back inside the machine, or store them in a sealed container nearby. Storing them separately can make it easier to confirm everything is dry.
- Choose a dry, temperature-stable storage location. Avoid areas with high humidity, extreme heat, or freezing temperatures. A pantry, closet, or dry basement shelf works well.
- Cover the machine with a breathable cloth. Use a cotton sheet, appliance cover, or clean towel. Avoid airtight plastic bags unless you are certain the machine is bone-dry, as trapped moisture can cause condensation.
- Store the coffee maker upright. Do not lay it on its side or stack heavy objects on top. Keep the power cord loosely coiled and away from sharp edges.
Short-Term vs. Long-Term Storage
The length of time you plan to store your Bunn coffee maker affects how much preparation is required. The table below outlines the key differences between short-term and long-term storage so you can choose the right approach.
| Storage Factor | Short-Term (Up to Two Weeks) | Long-Term (One Month or More) |
|---|---|---|
| Water reservoir | Empty completely | Empty completely and dry fully |
| Removable parts | Rinse and wipe | Wash, dry, and store separately if possible |
| Descaling | Optional unless scale is visible | Recommended before storage |
| Power cord | Unplug | Unplug and loosely coil |
| Covering | Light towel or leave uncovered | Breathable cover to prevent dust |
| Location | Countertop or cabinet | Closet, pantry, or dry storage room |
| Restart process | Rinse and brew a test pot | Full inspection, rinse, descale if needed, then brew |
For short-term storage, the goal is mainly to keep the machine clean and ready for the next morning. For long-term storage, the goal is preservation. You want to eliminate every source of moisture, mineral buildup, and dust so the brewer emerges from storage in the same condition it went in.
Best Storage Locations in Your Home
Where you store your Bunn coffee maker matters almost as much as how you clean it. The ideal spot is cool, dry, and protected from physical damage.
Kitchen Pantry or Cabinet
A kitchen pantry or lower cabinet is convenient and usually climate-controlled. Make sure the shelf is sturdy enough to support the weight of the machine, and keep it away from cleaning supplies or chemicals that could leak onto the brewer.
Basement or Utility Room
A finished basement can work well, but only if it is dry. Avoid damp basements where humidity promotes mold. If you store the machine in a utility room, keep it off the floor and away from washing machines or water heaters that might create moisture.
Garage or Storage Shed
Garages and sheds are generally not recommended for long-term storage because of temperature swings and humidity. If you must use a garage, place the coffee maker on a high shelf, cover it well, and bring it inside during extreme weather.
Countertop Storage
If you only need to store the machine for a few days, leaving it on the countertop is fine as long as it is unplugged, empty, and clean. Just cover it to keep dust out of the sprayhead and brew funnel.
Common Storage Mistakes to Avoid
Even well-intentioned owners sometimes make errors that damage their coffee makers. Here are the most frequent mistakes and how to avoid them.
- Leaving water inside the reservoir. Standing water is the leading cause of mold and mineral buildup. Always drain every drop before storage.
- Storing the machine while it is still damp. Moisture trapped under a cover creates condensation. Let all parts air dry completely first.
- Wrapping a warm coffee maker in plastic. Never cover the machine until it has cooled to room temperature. Heat trapped under plastic can damage components and encourage mildew.
- Storing near chemicals or cleaners. Fumes from bleach, ammonia, or solvents can affect plastic and rubber parts inside the brewer.
- Forgetting to unplug the machine. A plugged-in appliance is an unnecessary electrical risk during storage and can waste energy.
- Stacking heavy items on top. The top of a Bunn coffee maker is not designed to bear weight. Heavy boxes can crack the casing or damage internal tubing.
Tips and Best Practices for Storing a Bunn Coffee Maker
These best practices will help you get the most out of your stored Bunn coffee maker and avoid surprises when you bring it back into service.
- Use a breathable cover such as a cotton sheet or appliance bag rather than an airtight plastic container.
- Coil the power cord loosely and secure it with a twist tie or Velcro strap, but do not wrap it tightly around the machine.
- Label the storage date on a piece of tape attached to the cover so you know how long it has been stored.
- Check on the machine every few weeks if it is in long-term storage. Look for signs of pests, moisture, or dust accumulation.
- Keep the owner’s manual in the same storage area so you can reference descaling and cleaning instructions when you retrieve the machine.
- If you store the carafe separately, place a paper towel inside to absorb any residual moisture and prevent odors.
What to Do Before Using Your Bunn Coffee Maker Again
Retrieving your Bunn coffee maker from storage requires a few simple steps to ensure it is safe and ready to brew great coffee.
- Inspect the machine. Look for dust, spiderwebs, or signs of pests. Wipe the exterior with a clean, damp cloth.
- Reassemble all parts. Place the sprayhead, brew funnel, and carafe back in their proper positions. Make sure everything is seated correctly.
- Fill the reservoir with fresh water. Do not use water that has been sitting in the machine during storage.
- Run a water-only brew cycle. Brew a full pot of plain water to flush out the internal system and remove any stale tastes or odors.
- Discard the first pot. Pour out the water-only brew and rinse the carafe.
- Brew a test pot with coffee. Use fresh grounds and brew a normal pot. If the taste and aroma seem normal, your Bunn coffee maker is ready for regular use.
If the machine has been in storage for several months, consider running a descaling cycle before brewing coffee, especially if you live in a hard-water area.
Bunn Model-Specific Considerations
Bunn makes several types of coffee makers, and storage needs can vary slightly by model.
Home automatic drip models usually have a glass or thermal carafe and a built-in warming plate. These are relatively simple to store: empty the reservoir, wash the carafe, and keep the machine upright.
Pour-over Bunn brewers, common in offices and small cafes, do not always have a warming plate but still hold water in an internal tank. The same draining and drying rules apply, but pay extra attention to the sprayhead area, which can clog more easily in high-volume machines.
Commercial Bunn coffee makers are larger and often plumbed directly into a water line. If you are storing a commercial unit, you may need to shut off the water supply, disconnect the line, and drain the tank completely. Consult the commercial manual before attempting storage, as these machines have more complex plumbing.
Regardless of the model, the core principle remains the same: no water, no moisture, no power, and a clean, dry environment.
Frequently Asked Questions
Can I store my Bunn coffee maker with water in it?
No. You should never store a Bunn coffee maker with water left in the reservoir or internal tank. Standing water can become stale, grow mold, and lead to mineral deposits that are difficult to remove later. Always empty and dry the machine completely before storage.
How long can a Bunn coffee maker be stored?
A Bunn coffee maker can be stored indefinitely as long as it is cleaned, dried, and kept in a suitable environment. Machines stored for several months or even years can return to service after a thorough inspection, rinse, and test brew.
Do I need to descale before storage?
Descaling is not mandatory for every storage situation, but it is strongly recommended if you have hard water or if it has been a while since your last descaling. Removing scale before storage prevents it from hardening and makes the machine easier to restart later.
Can I store a Bunn coffee maker in the garage?
You can store a Bunn coffee maker in a garage for short periods, but it is not ideal for long-term storage. Temperature fluctuations and humidity can damage the machine. If you must use a garage, keep the brewer on a shelf, cover it with a breathable cloth, and avoid storing it during freezing or extremely hot weather.
How do I prevent mold during storage?
The best way to prevent mold is to eliminate moisture. Empty all water, wash removable parts, and let every surface air dry completely before covering the machine. Store it in a dry location and avoid airtight plastic wrapping unless you are certain no moisture remains.
Should I leave the lid open or closed during storage?
If you are storing the machine on a shelf where dust is not a concern, leaving the lid slightly open can help air circulate and prevent trapped moisture. However, if dust is likely, cover the machine with a breathable cloth and keep the lid closed to protect the interior.
Conclusion
Learning how to store a Bunn coffee maker is simple when you break it down into clear steps. The process starts with unplugging the machine, letting it cool, and emptying every drop of water from the reservoir. Cleaning the sprayhead, brew funnel, and exterior removes coffee oils and mineral deposits that could cause odors or buildup during storage.
Drying the machine completely is just as important as cleaning it. Moisture left inside the brewer can lead to mold, mildew, and unpleasant tastes when you are ready to brew again. Choosing a cool, dry storage location and using a breathable cover will protect the appliance from dust, pests, and environmental damage.
When the time comes to use your Bunn coffee maker again, a quick inspection, fresh water fill, and a water-only brew cycle will confirm that everything is working properly. Whether you are storing the machine for a few weeks or several months, following these guidelines ensures that your coffee maker will be ready to deliver fast, great-tasting coffee whenever you need it.
Proper storage is one of the easiest ways to protect your investment and extend the life of your Bunn coffee maker. With the right preparation, you can store your brewer with confidence and enjoy fresh coffee for many years to come.
