Reasons why your Keurig frother is not working and how to fix

Below are some of the reasons why your Keurig frother isn’t working.

You haven’t added milk.

One of the reasons could be that you simply forgot to add milk to the frother. Don’t worry; this happens to most of us, especially early in the morning. If this is the case, simply add fresh milk and proceed.

You have added excess milk.

Another reason could be that you’ve added excess milk into the frother. If you use too much milk in the Keurig frother, it’ll start spilling the milk all over the place or stop working altogether. To know whether you’ve used excess milk, simply check the two indicator lines inside the frother on the walls, and if the milk has exceeded the bottom line, then it’s excess; therefore, reduce it. The bottom line is where the milk is supposed to reach when you want to froth, while the top line is where the milk should reach when you’re not frothing.

You’re trying to brew coffee and froth milk at the same time

For a Keurig coffee machine with a frother, if you try to brew coffee and froth milk simultaneously, the frother won’t work. If this is the case, simply be patient and let the coffee brew first, then proceed to froth your milk as usual. One process needs to take place at a time.

You’re using the wrong kind of milk.

Also, if you’re using the wrong milk, your Keurig frother will stop working. This is surprising to many, but using the wrong kind of milk in the Keurig frother will yield that it isn’t properly frothed. Not all kinds of milk are similar, as others contain more protein, sugars, and fat than others.

Typically fattier milk kinds like 2% milk or whole milk work the best in Keurig frothers. The fattier the milk, the more smooth and perfectly textured the froth will be. Generally, plant-based milk, like soy, coconut, rice, and macadamia, aren’t the best for Keurig frothers as they form bubbles that dissipate just as quickly as they were formed. Almond milk is considered the better non-dairy milk for a Keurig frother, although the quality of the output won’t match that of dairy milk. If you had placed a plant-based in the frother, try replacing it with dairy milk, like 2% milk.

The frother’s whisk is dirty.

Another reason your Keurig frother isn’t working could be because the whisk contains build-up dirt or gunk. If you don’t clean your Keurig frother after every use, then you risk dirt, dust, and guck sticking on the appliance, including the magnetic whisk. This dirt could be from dust or milk residue and could interfere with the magnetic force, making the Keurig frother stop working.

If you think this might be the case for you, add a tablespoon of salt to a cup of vinegar and soak the whisk inside the mixture for up to 24 hours. After which, you’ll gently scrub any remaining dirt with a soft brush, then rinse the whisk under water, dry it thoroughly, and place it back in its place. Alternatively, simply soak the whisk in warm, soap water and gently scrub it after a few hours.

A faulty heating element

A burn-out heating element can also be the cause of why your Keurig frother has stopped working. If you suspect this is the issue, it’s best to call a professional to do it, as it involves electricity. However, if you’re good at fixing electrical appliances, simply contact the company’s customer care desk, and they’ll guide you on how to fix it.

A faulty whisk

A broken whisk can also be the reason your frother isn’t working. If this is the case for you, you’ll have to buy a replacement whisk, as a broken whisk cannot be repaired. Replacement frother whisks are easily available online as well as in stores.

You haven’t placed covered the frother with its lid

Your Keurig frother might have stopped working because you didn’t put the lid on. Without its lid, a Keurig frother won’t work, so simply cover the frother properly if this is the case for you.

The frother isn’t properly attached at the base.

Lastly, if your Keurig frother isn’t placed properly on the base, the frother won’t work. An unstable Keurig frother won’t work since there’s no electrical contact to power the appliance. Note that this instability can also be because of the build-up of dirt and dust on the appliance.


Do I need to replace a Keurig frother that is not working?

Not after carefully examining the possible reasons why this occurred because most of the issues can be resolved at home.

Which parts of a Keurig frother can be replaced if it’s not working?

The parts that are typically replaced are the whisk and frother lid. Without these parts, the frother won’t work.

How long do Keurig frothers last before they stop working?

Before it stops working, Keurig frothers can last up to 3-5 years, depending on how well the appliance is cared for.

What milk should I use in my Keurig frother?

Dairy milk is arguably the best for Keurig frother or any other dairy milk.

How much milk can I put in my Keurig frother?

The milk should be poured into the frother without exceeding the bottom line.
