How to Clean and Maintain Your Franklin Beverage Dispenser

Franklin beverage dispensers need weekly cleaning of the tap and monthly deep cleaning of the internal lines to stay fresh and prevent mold

Franklin dispensers—whether they hold water, juice, or tea—accumulate mineral deposits, mold, and bacteria in places you cannot see. The tap gets grimy from daily use. The internal tubing collects sediment and biofilm. If you skip cleaning, the water tastes stale, the dispenser smells sour, and you risk drinking contaminated liquid. A simple routine keeps everything safe and tasting right.

The good news: you do not need special tools or expensive cleaners. Hot water, white vinegar, and a bottle brush handle most jobs. The key is doing it regularly—weekly for the visible parts, monthly for the lines—rather than waiting until something goes wrong.

Key Takeaways

• Clean the tap and drip tray every week with hot soapy water and a soft brush to prevent mold and mineral buildup.
• Run white vinegar through the internal lines once a month to dissolve deposits and kill bacteria that cause odors.
• Replace the water bottle or refill the reservoir according to your Franklin model's instructions, and wipe the connection point each time.
• Store your dispenser away from direct sunlight and keep the area around it dry to slow mold growth.
• If water tastes metallic or smells sour even after cleaning, the internal filter may need replacement—check your manual for the part number.

Weekly cleaning: the tap, drip tray, and exterior

The tap is where your hands touch the dispenser most, and where water sits between uses. Mineral deposits and mold build up fast. Every time you use it, a small amount of water drips into the tray below and evaporates, leaving behind minerals and bacteria.

Remove the drip tray (it usually slides out or unbolts from underneath). Empty any standing water. Scrub the tray with hot soapy water and a soft brush or cloth—a toothbrush works well for corners. Rinse thoroughly and dry it before sliding it back in.

For the tap itself, soak a cloth in hot soapy water and wrap it around the spout for a few minutes to soften deposits. Use a soft brush or old toothbrush to gently scrub the tap opening and the underside where water pools. Rinse with clean water and dry with a cloth. Wipe down the exterior of the dispenser with a damp cloth to remove dust and spills.

Monthly deep cleaning: flushing the internal lines

Water sits in the internal tubing between uses, and that is where mold and bacteria grow. You cannot see inside, but you can flush out what is there using white vinegar, which dissolves mineral deposits and kills microbes without harming the plastic.

Fill a clean bucket or large bowl with equal parts white vinegar and hot water. Disconnect the water bottle or open the reservoir cap. Using a clean funnel or a cup, slowly pour the vinegar solution into the water inlet (the opening where the bottle connects or where you pour water in). Let it sit for 15 to 20 minutes so the vinegar can work through the lines.

Then run the vinegar solution through the tap into a sink or bucket. You may hear gurgling or see cloudy water—that is the vinegar loosening buildup. Keep running it until the water runs clear. After that, repeat the process with plain hot water two or three times to rinse out all the vinegar smell and taste.

Replacing the water bottle or refilling the reservoir

Every time you change the bottle or refill the reservoir, the connection point gets handled and exposed to air. This is where contamination sneaks in. Before you attach a new bottle or pour in fresh water, wipe the connection point—the rim of the inlet and the top of the bottle neck if you are using a bottle—with a clean, damp cloth. Let it air-dry for a few seconds.

If your Franklin uses a refillable reservoir, empty it completely and rinse it with hot water before refilling. Do not just top it off. If you use bottled water, check the bottle for cracks or cloudiness before inserting it. Store bottles in a cool, dry place away from sunlight, which can degrade the plastic and allow bacteria to grow.

Preventing odors and mold growth

Mold thrives in warm, damp, dark places—exactly what the inside of a water dispenser can become. You cannot eliminate mold entirely, but you can slow it down by controlling the environment around the dispenser.

Keep the dispenser away from direct sunlight and away from heat sources like radiators or ovens. Make sure the area underneath and around it stays dry—wipe up spills right away, and do not let the drip tray overflow. If the room is very humid, run a fan or dehumidifier nearby to keep air moving.

If you notice a sour or musty smell even after cleaning, the problem may be deeper in the system. Some Franklin models have a replaceable filter cartridge inside the tank. Check your manual to see if your model has one, and replace it according to the schedule listed. A clogged or old filter traps bacteria and causes odors.

Troubleshooting common problems

If water tastes metallic or bitter, mineral buildup is likely. Run the vinegar flush described above, then rinse thoroughly with plain hot water at least three times. If the taste persists, the internal filter may be saturated and need replacement.

If water comes out slowly or stops flowing, sediment or mineral deposits are blocking the line. Try the vinegar flush again, letting it sit for 30 minutes instead of 15. If that does not work, you may need to disassemble the inlet valve—your manual will show you how, or you can contact Franklin customer service for a replacement valve.

If the dispenser leaks from the bottom, the drip tray may be full or the seal between the tank and the tap assembly may be worn. Empty the tray first. If leaking continues, the seal needs replacement—this is a job for the manufacturer or a repair service, as it involves opening the sealed tank.

Storing your Franklin when not in use

If you are storing the dispenser for more than a few weeks—during a move, seasonal storage, or if you are switching to a different model—empty it completely and let it dry inside. Leave the cap or bottle connection open so air can circulate. Store it in a cool, dry place, not in a basement or garage where humidity is high.

Before you use it again, run hot water through the tap for 30 seconds to flush out any dust or debris that settled during storage. Then run the vinegar flush once to clean the lines, rinse with hot water, and you are ready to go.

Frequently Asked Questions

How often should I replace the water bottle?

That depends on how much water your household uses. A typical 5-gallon bottle lasts one to two weeks for a family of four. Check the bottle for visible cloudiness, sediment, or an off smell—those are signs it is time to replace it, regardless of how long it has been sitting. Store unopened bottles in a cool, dark place, not in direct sunlight.

Can I use bleach to clean the inside of my Franklin?

No. Bleach can leave residue in the plastic tubing and may leach into the water. Stick to white vinegar and hot water for internal cleaning. For the exterior and drip tray, a small amount of mild dish soap is fine, but rinse thoroughly.

Why does my water smell like plastic?

New dispensers or new bottles sometimes smell like plastic for the first few uses. Run hot water through the tap for a minute or two to flush out the smell. If the smell persists after several uses, or if it is a used dispenser, the plastic may be degrading from heat or age—consider replacing the unit.

What if I see mold inside the tank?

If you can see mold on the inside walls of the tank, the vinegar flush may not reach it all. Empty the dispenser, fill it halfway with the vinegar-and-water solution, and let it sit for an hour. Shake it gently a few times during that hour. Then drain and rinse thoroughly with hot water at least four times. If mold returns quickly, the tank seal may be compromised and the unit may need replacement.

Do I need to clean the dispenser if I only use it for cold water?

Yes. Cold water does not kill bacteria or mold—it just slows their growth. Mold still forms in the lines and tap, especially if the dispenser sits in a warm room. Follow the same weekly and monthly cleaning schedule regardless of water temperature.
