When a kitchen mixer starts making a grinding noise, it can be both alarming and disruptive. We know how frustrating it is when your trusted appliance begins acting up out of nowhere. That sound often signals something mechanical inside is no longer moving the way it should. Therefore, it’s worth taking a few moments to investigate before the issue gets worse.
Sometimes it’s a quick fix. In other cases, it might call for professional attention. However, knowing what you’re dealing with can help you decide what step to take next. Let’s walk through the common causes of grinding sounds and what you can do about them.
Worn or Stripped Gears Inside the Mixer
Mixers rely on a series of internal gears to transfer motor power to the beaters. These gears can wear down over time, especially if the mixer is frequently used on thick batters or doughs. In other words, if your machine is grinding through years of use, the internal components might be giving out.
That grinding noise is often the sound of teeth slipping on worn-out gears. Likewise, if grease has leaked out from the gearbox, the gears could be rubbing together dry, making the sound even worse. Replacing the gear or re-greasing the assembly can help, but you’ll need to open the casing to confirm. If you’re unsure how to do this safely, booking mixer repair services in Calgary might be your best bet.
Loose Planetary Assembly or Shaft Components
Another possible cause is the planetary assembly—the part that spins around and drives the beater shaft. Over time, this section can loosen or misalign. Consequently, it starts rubbing against other internal parts, which can lead to a persistent grinding or clicking noise.
We’ve also seen cases where the beater shaft isn’t seated correctly. When that happens, the spinning parts inside don’t engage smoothly, and the misalignment creates a grinding sound. You can try removing the beater attachment and reinstalling it with a firm push. If the noise persists, the problem likely goes deeper.
Additionally, if the retaining pin or collar has slipped, that could contribute to the unwanted noise. A simple tightening or realignment may be all that’s needed. But if the grinding continues even after checking the outside parts, it’s a good idea to stop using the mixer to prevent further damage.
Old Grease or Lack of Lubrication
Grease plays a big role in keeping your mixer running smoothly. However, grease does not last forever. Over time, it can dry out, become sticky, or simply migrate away from the parts that need it most. As a result, metal components start to grind against each other, causing noise and wear.
Most stand mixers use food-grade grease inside the gearbox to cushion the gears. If that grease has broken down, you’ll often hear a harsher sound when mixing, especially under load. You might even spot grease leaking around the seams of the mixer head, which is a clear sign it needs replacing.
Servicing the mixer by removing the old grease and applying new lubricant can restore quiet operation. This process involves opening the casing and cleaning out the old grease thoroughly. We usually recommend that step be handled by those with the right tools and know-how. If you’re unsure, our mixer repair services in Calgary can safely handle a full regrease for you.
Bearings or Motor Issues
Bearings help keep the moving parts of your mixer stable and spinning with minimal resistance. But if these bearings are worn or dirty, they can create a scraping or grinding noise that’s easy to confuse with gear problems.
One way to narrow this down is to listen closely. If the noise happens even when the mixer is running without any attachments, the problem could be inside the motor or bearing assemblies. On the other hand, if it only happens under load, the strain could be highlighting an issue in the gearbox or beater mechanism.
Motor brushes may also play a role here. These components wear down over time and can start making contact in unintended ways. Therefore, it’s a smart move to check both bearings and motor components if the sound doesn’t seem to match other common causes.
Foreign Objects Inside the Mixer
This one might sound strange, but it happens more often than you’d think. Small pieces of metal, food particles, or even broken bits from a past repair can find their way into the mixer’s internal components. Consequently, these objects cause a noticeable grinding sound as they interfere with normal movement.
If you’ve recently opened the mixer or changed any internal parts, this possibility becomes more likely. Likewise, if you store your mixer in a space where dust, flour, or debris collects easily, some of it might work its way inside.
To clarify, opening the machine without knowing exactly what to look for can sometimes make the issue worse. In these cases, a professional eye can spot the issue quickly and make sure nothing’s missed. If you’re unsure how to proceed, you can contact Mixer Repair Services Calgary and ask for a quick diagnosis.
When to Stop Using the Mixer
We always say this—when in doubt, stop using the machine. If the grinding sound appears suddenly and loudly, it might be a sign something serious has gone wrong inside. Continuing to run the mixer in this state could lead to bigger damage or even motor failure.
Sometimes, we’ve seen mixers that came in with small issues that turned into expensive repairs because they were used too long in a damaged condition. Therefore, it’s worth taking a break, unplugging the unit, and either opening it up carefully or reaching out for help.
There are DIY repair videos out there, but be cautious. Not every mixer is built the same, and trying to fix one without knowing its layout can lead to more broken parts.
How to Prevent Grinding Issues in the Future
Most grinding sounds are avoidable with regular maintenance. We suggest checking your mixer’s attachment connections often and listening closely to how it sounds when mixing.
In addition, try not to overload the bowl. While mixers are tough, pushing them past their design limits wears out parts much faster. Use the right speed setting for the job and give the mixer time to work through heavy batters.
Every year or so, it’s smart to have a check-up done. Just like any machine, mixers benefit from inspection and cleaning. If it’s been a while since yours was serviced, booking reliable mixer repair services in Calgary can extend its life and keep it quiet for years to come.
Quick Tip: Smell the Mixer
One insight most people overlook is the smell test. If your mixer is grinding and you catch a faint burnt or metallic smell, that’s a red flag. It often means the motor is overheating or internal grease is breaking down. That detail can help you figure out the urgency of the issue even before opening anything up.

Frequently Asked Questions
What causes my mixer to grind only at higher speeds?
This could point to worn gears or inadequate lubrication. At high speeds, the strain increases, making weak spots more noticeable.
Is it safe to keep using my mixer if the grinding sound is faint?
Not really. Even faint grinding means parts are rubbing or slipping. Using the mixer may make it worse over time.
Can I open the mixer myself to check for issues?
You can if you’re familiar with appliance repair and have the right tools. However, many internal parts are delicate and easy to damage.
What’s the cost to repair a grinding mixer?
It depends on the part involved. Simple fixes like re-greasing are less expensive, while gear or motor replacement costs more.
How long does a mixer repair typically take?
For common issues like gear replacement or lubrication, most repairs are done within a couple of business days if parts are in stock.
