How to Clean and Maintain Your Bloomfield Coffee Maker

What a Bloomfield coffee maker is and why it matters for your kitchen

Bloomfield is a commercial-grade coffee maker brand built for high-volume brewing—the kind you see in office break rooms, restaurants, and cafés. Unlike home machines that brew one or two cups at a time, Bloomfield makers hold several gallons and keep coffee hot throughout the day. If you own one, you're working with equipment designed to run continuously, which means it needs a different cleaning and maintenance routine than a standard home coffee maker.

The reason maintenance matters is straightforward: Bloomfield machines are expensive, and they fail faster when mineral buildup, old coffee oils, and sediment clog the internal lines. A machine that costs hundreds or thousands of dollars to replace will last years longer if you follow a regular schedule. You'll also notice better-tasting coffee—stale oils and mineral deposits change the flavor noticeably.

Key Takeaways

• Bloomfield coffee makers need daily rinsing of the brew basket and carafe, plus a weekly deep clean with a commercial descaling solution designed for high-volume machines.
• Mineral deposits build up inside the heating element and water lines, so descaling every one to three months (depending on water hardness) prevents slow brewing and weak coffee.
• The spray head—the part that distributes water over the grounds—clogs easily and should be soaked and brushed weekly to keep water flowing evenly.
• Bloomfield machines use specific replacement parts like brew baskets and gaskets; using generic parts can damage the machine or void any warranty.
• If your machine brews slowly, produces weak coffee, or leaks, the problem is usually mineral buildup or a clogged spray head, not a broken machine.

Daily cleaning to prevent buildup and odors

Every time you finish brewing, rinse the brew basket under hot running water while it's still warm. Use your fingers or a soft brush to remove grounds stuck to the sides and bottom. Don't let grounds sit in the basket—they oxidize and create stale, bitter flavors that transfer to the next pot. If your machine has a removable spray head (the perforated part at the top), lift it out and rinse it too.

Empty the carafe completely and rinse it with hot water. If coffee has been sitting for more than two hours, dump it and wash the carafe with a brush or cloth to remove the oily film that builds up. This film is old coffee oxidizing, and it makes fresh coffee taste rancid. Dry the carafe with a clean cloth before putting it back, or leave it to air-dry if you're not brewing again immediately.

Wipe down the outside of the machine and the warming plate with a damp cloth. Spilled coffee hardens on the plate and can smoke or burn the next time you brew. If your machine has a water reservoir, check that it's filled to the line marked on the side—running out of water mid-brew can damage the heating element.

Weekly deep cleaning with descaling solution

Once a week, run a descaling cycle using a commercial descaling solution made for coffee machines. Do not use vinegar on a Bloomfield machine—vinegar is too weak for the mineral deposits in commercial equipment and can leave a vinegar taste in the machine. Instead, buy a descaling powder or liquid labeled for commercial coffee makers; brands like Cafiza or Dripkit are common and work well.

Fill the water reservoir with water and add the descaling solution according to the package directions. Run the machine as if you were brewing, but let the solution flow through without grounds in the basket. Let the solution sit in the carafe for 15 to 20 minutes, then run another cycle. Empty the carafe and run two full cycles of plain water through the machine to rinse out all the descaling solution. If you skip the rinse cycles, your next pot of coffee will taste chemical and bitter.

While the machine is running its descaling cycle, soak the removable spray head in a bowl of the same descaling solution for 15 minutes. Use an old toothbrush or a small soft brush to scrub the holes in the spray head—mineral deposits clog these holes and cause uneven water distribution. Rinse the spray head under hot running water and let it air-dry before putting it back in the machine.

Handling mineral deposits and slow brewing

If your Bloomfield machine starts brewing slowly—taking longer than usual to fill the carafe—mineral buildup is almost always the cause. Hard water leaves calcium and magnesium deposits inside the heating element and water lines. The machine still works, but water has to push harder to get through, so brewing takes longer and the coffee may taste weak because water isn't hot enough by the time it reaches the grounds.

Run a full descaling cycle as described above. If the machine is very slow, you may need to descale twice in one week. After that, descale every month if you have hard water (water that leaves white spots on dishes or feels slippery), or every three months if you have soft water. If you're not sure about your water hardness, ask your local water utility or buy a test strip at a hardware store.

If descaling doesn't speed up the brewing, the heating element itself may be severely clogged. At that point, you'll need to contact Bloomfield customer service or a commercial coffee equipment repair shop—internal parts may need to be replaced.

Replacing parts and when to call for service

Bloomfield machines have several parts that wear out or need replacing: brew baskets, carafe gaskets (rubber seals), and spray heads. Always order replacement parts directly from Bloomfield or from an authorized distributor, not from generic online retailers. Using the wrong gasket size or material can cause leaks or damage the heating element. Check your machine's model number (usually on a sticker on the back or bottom) before ordering anything.

If your machine leaks from the bottom, the gasket under the brew basket is worn out and needs replacing. If water drips from the sides of the carafe, the carafe itself may be cracked or the gasket is damaged. If the machine won't turn on or the heating element doesn't warm up, contact a repair service—these are electrical issues that require professional work.

Keep your machine's manual or look up the model number online to find the parts diagram. Most Bloomfield machines have a parts list showing exactly which gaskets, baskets, and seals fit your model. Ordering the right part takes five minutes and saves you from installing something that doesn't fit.

Storing your machine and seasonal maintenance

If you're storing a Bloomfield machine for more than a few weeks—during a seasonal closure or renovation—drain the water reservoir completely and run a full descaling cycle before you shut it down. This prevents stagnant water from growing mold or bacteria inside the lines. After descaling, run two cycles of plain water to rinse, then turn off the machine and let it cool.

Before you start using the machine again after storage, repeat the descaling and rinsing process. Water that's been sitting in the lines for weeks can taste stale, and any mold spores need to be flushed out. Run one full pot through without grounds to make sure the water tastes clean, then brew normally.

If you live in a very cold climate and the machine will be exposed to freezing temperatures, drain the water reservoir and lines completely. Frozen water can crack the heating element or burst water lines. Check your manual for specific winterization steps for your model.

Troubleshooting common problems

If your coffee tastes bitter or burnt, the warming plate may be too hot or the machine hasn't been cleaned in a while. Run a descaling cycle and check that the carafe isn't sitting on the warming plate for more than two hours after brewing stops. If the machine has a temperature dial, turn it down slightly and see if the taste improves.

If the machine brews unevenly—some grounds are wet and some are dry—the spray head is clogged. Remove it, soak it in descaling solution for 20 minutes, and brush out the holes. Uneven brewing also happens if you're using too fine a grind; ask your coffee supplier for a medium grind designed for commercial machines.

If water leaks from the sides of the carafe or from under the machine, turn it off immediately and check the gasket under the brew basket. If it's cracked or discolored, order a replacement. If the gasket looks fine, the carafe may be cracked—hold it up to the light and look for hairline cracks. A cracked carafe can't be repaired and needs to be replaced.

Frequently Asked Questions

Can I use vinegar to descale my Bloomfield machine?

No. Vinegar is too weak for commercial coffee makers and won't dissolve mineral deposits effectively. Use a commercial descaling solution made for coffee machines instead. Vinegar can also leave a lingering taste in the machine even after rinsing.

How often should I descale if I use my machine every day?

Descale weekly if you have hard water, or every two to three weeks if you have soft water. If your machine starts brewing slowly before the scheduled time, descale immediately—don't wait for the regular schedule.

What should I do if my machine stops heating water?

First, make sure the machine is plugged in and turned on. If it is, the heating element may have failed or there's an electrical problem. Contact a commercial coffee equipment repair shop or Bloomfield customer service—this isn't something you can fix yourself.

Is it normal for the machine to drip after I remove the carafe?

A few drops are normal, but steady dripping means the gasket under the brew basket is worn out or the carafe isn't seated properly. Make sure the carafe is pushed all the way up into the machine, and if dripping continues, order a replacement gasket.

Can I use a different brand's carafe or brew basket?

No. Bloomfield parts are sized specifically for each model, and using a different brand's parts can cause leaks, uneven brewing, or damage to the machine. Always order replacement parts from Bloomfield or an authorized distributor.
