If you’re a coffee enthusiast in the U.S., you know that a Keurig coffee maker is more than just a machine—it’s your daily companion, delivering that much-needed caffeine kick. But what happens when your Keurig frother stops working? Don’t worry; you’re not alone, and most issues can be resolved with a little troubleshooting.

Common Keurig Frother Problems
Before diving into solutions, let’s identify the typical issues users face:
- Frother not turning on: The frother remains unresponsive.
- Milk heats but doesn’t froth: The milk warms up but doesn’t achieve the desired frothy texture.
- Whisk not spinning: The whisk inside the frother isn’t rotating.
- Lights flashing: Indicator lights blink without the frother functioning properly.
Keurig Milk Frother: Step-by-Step Troubleshooting
1. Ensure Proper Milk Level
Always fill the frother below the maximum fill line. Overfilling can prevent proper frothing and may cause the machine to malfunction.
2. Check for Milk Presence
The frother requires milk to operate. Ensure you’ve added milk before starting the frothing process.
3. Verify Whisk Placement
The whisk should be securely placed at the bottom of the frother. An improperly seated whisk can hinder the frothing process.
4. Properly Seat the Frother on the Base
Ensure the frother is correctly positioned on its base. Misalignment can prevent the frother from operating.
5. Use the Correct Milk Type
Different milk types froth differently. Whole milk and 2% milk generally froth better than skim or non-dairy alternatives.
6. Avoid Simultaneous Brewing and Frothing
Attempting to brew coffee while frothing milk can overload the machine. Wait for the brewing process to complete before starting the frothing.
7. Clean the Frother Regularly
Milk residue can build up and affect performance. Clean the frother after each use to maintain optimal functionality.
8. Perform a System Reset
Unplug the machine, wait for 30 seconds, then plug it back in. This can resolve minor glitches.

Deep Cleaning Tips
Over time, milk residue can accumulate, affecting the frother’s performance. Here’s how to deep clean your frother:
- Disassemble the Frother: Remove the whisk and lid.
- Soak Components: Place the whisk and lid in warm, soapy water for a few minutes.
- Clean the Base: Wipe the base with a damp cloth.
- Rinse Thoroughly: Ensure all parts are free from soap residue.
- Dry Completely: Allow all components to dry before reassembling.
Tips for Frothing Non-Dairy Milk
Non-dairy milks like almond, soy, or oat milk can be trickier to froth. Consider these tips:
- Choose Barista Blends: These are formulated to froth better.
- Use Fresh Milk: Older milk may not froth well.
- Adjust Temperature: Heat non-dairy milk to a lower temperature to prevent separation.
Advanced Troubleshooting
If basic steps don’t resolve the issue:
- Check for Obstructions: Ensure there are no blockages in the frother’s components.
- Inspect for Damage: Look for any visible signs of wear or damage.
- Consult Customer Support: If problems persist, contact Keurig’s customer service for assistance.
