Why Is My Kitchenaid Stand Mixer Leaking Oil? Understanding Common Causes and Effective Solutions

ByHelen Stahl Updated

Why Is My Kitchenaid Stand Mixer Leaking Oil?

If your KitchenAid stand mixer is leaking oil, it is likely because the oil has separated from the grease inside the machine.

This is a normal occurrence due to the lifetime’s worth of solid grease that is used to lubricate the mixer.

While the leak may be small and if the machine sounds normal, it is still safe to use.

To prevent further leaks, run the machine at speed 10 without ingredients for two minutes and wipe away any excess oil.

It is also important to let the mixer cool completely between uses to avoid overheating and oil leaks.

The oil leak will not cause damage to the machine as the grease used is food grade.

However, if excessive oil leaking occurs and running the machine without ingredients doesn’t help, repairs may be needed.

KitchenAid offers “shipping kits” to send your mixer for repairs to their factory in Ohio, and you can also contact KitchenAid to find out if there are any service centers near you.

Key Points:

  • KitchenAid stand mixer may leak oil if the oil has separated from the grease inside.
  • Leaking oil is a normal occurrence due to solid grease used for lubrication.
  • If the leak is small and the machine sounds normal, it is safe to use.
  • To prevent further leaks, run the machine at speed 10 without ingredients for 2 minutes and wipe away excess oil.
  • Letting the mixer cool completely between uses helps avoid overheating and oil leaks.
  • The grease used is food grade, so the oil leak will not cause damage to the machine.

Did You Know?

1. KitchenAid stand mixers are designed with a built-in lubrication system that requires food-grade grease. Over time, this grease may separate or break down, causing oil to leak from the mixer.

2. The most common reason for oil leakage in KitchenAid stand mixers is overuse or misuse. When the mixer is run at high speeds for prolonged periods or is overloaded with heavy ingredients, the excess heat generated can cause the grease to melt and leak out.

3. If you notice oil leakage from your KitchenAid stand mixer, it is recommended to immediately stop using it and inspect the attachment hub. Sometimes, the oil can leak from the attachment hub cover, indicating that the attachment pin may need replacement or tightening.

4. Temperature changes can play a role in oil leakage. If you frequently store your KitchenAid stand mixer in a cold environment, such as a garage or basement, the cold temperature can cause the grease to solidify and create a pressure imbalance that leads to oil leakage when the mixer is used again.

5. Although oil leakage is generally a rare occurrence, it can also happen as a result of a manufacturing defect. If your KitchenAid stand mixer consistently leaks oil despite proper usage and maintenance, it is advisable to contact the manufacturer’s customer support or reach out to a certified service center for assistance.

1. Small Amount Of Oil Leakage In KitchenAid Stand Mixers

KitchenAid stand mixers are known for their durability and reliability. However, it is not uncommon for these appliances to have a small amount of oil leakage over time. The oil leakage may concern some users, but it is typically not something to be alarmed about. As long as the machine sounds normal and functions properly, it is safe to continue using it.

Key points:

  • KitchenAid stand mixers are durable and dependable.
  • Oil leakage is a common issue over time.
  • No cause for alarm unless the machine has abnormal sounds or malfunctions.

2. Importance Of Proper Lubrication In KitchenAid Stand Mixers

To understand why oil leakage may occur in KitchenAid stand mixers, it’s important to recognize the role of lubrication in these machines. Proper lubrication is essential for smooth and efficient operation, as it reduces friction and wear on moving components. KitchenAid stand mixers come with a lifetime’s worth of solid grease inside, which serves as the primary lubricant. This grease is of food-grade quality and is specifically designed to ensure the longevity and reliability of the appliance.

3. Understanding The Oil Leak From The Beater Shaft

In certain cases, oil may separate from the solid grease in the machine and leak out from the beater shaft. This can occur when the machine is not used for extended periods or when exposed to extreme temperatures. While the oil leakage may initially raise concerns, it is crucial to note that it will not harm the mixer. The food-grade grease remains unaffected and continues to lubricate the machine’s components.

  • Oil may separate from solid grease and leak out from the beater shaft
  • Factors causing oil leakage include extended periods of non-use and exposure to extreme temperatures

“It is important to remember that this will not cause any damage to the mixer itself.”

4. Preventing Leaks By Running The Mixer At Speed 10

To prevent oil leaks, running the mixer at speed 10 for two minutes without any ingredients is recommended. This action helps redistribute the grease and keeps it properly mixed, preventing the separation of oil. Additionally, wiping away any excess oil after performing this maintenance routine can help maintain cleanliness and minimize the chance of oil drips during use.

5. Cooling The Mixer Between Uses To Avoid Overheating And Leaks

Another important factor to consider in preventing oil leakage is allowing the mixer to cool completely between uses. Overheating the machine can cause the grease to become too liquid, increasing the likelihood of oil separating and leaking. Therefore, it is advisable to give the mixer adequate cooling time before each use. This not only protects against oil leaks but also helps to prolong the lifespan of the appliance.

6. Seeking Repairs For Excessive Oil Leakage In KitchenAid Stand Mixers

While a small amount of oil leakage is normal and should not cause concern, if you notice excessive oil leaking that persists even after running the machine without ingredients, it may be necessary to seek repairs. For such cases, KitchenAid offers “shipping kits” that allow users to send their mixers to their factory in Greenville, Ohio for professional repairs. Alternatively, you can contact KitchenAid to inquire about any authorized service centers near you that can assist with resolving the issue.

  • To minimize the likelihood of oil leaks, follow these preventative measures:
  • Run the mixer at speed 10 without ingredients.
  • Ensure adequate cooling between uses.

In conclusion, oil leakage in KitchenAid stand mixers is a common occurrence, typically resulting from the separation of oil from the solid grease inside the machine. However, this does not cause any harm to the appliance or compromise its performance. By following preventative measures such as running the mixer at speed 10 without ingredients and ensuring adequate cooling between uses, users can minimize the likelihood of oil leaks. In the event of excessive oil leakage, KitchenAid provides repair options to restore the mixer to its optimal working condition.

Frequently Asked Questions

Do KitchenAid mixers need to be lubricated?

Yes, KitchenAid mixers do require lubrication for optimal performance. Within the machine lies a generous amount of solid grease that serves to lubricate the gears and facilitate smooth mixing and whipping.

Why is my KitchenAid mixer leaking brown fluid?

When the grease inside the gearbox of a KitchenAid mixer separates, it can cause the mixer to leak brown fluid. This occurs when the liquid part of the grease separates and leaks out as an oil. There are several reasons why the grease inside the gearbox may separate, including overloading the mixer and subjecting it to excessive heat. Additionally, if the mixer is not used frequently or has been in use for a long time, the grease may also separate and cause the leakage.

Why is my mixer leaking?

A possible reason for your mixer leaking could be a loosened or damaged connection between the water supply and the tap. It’s essential to check these connections as they can weaken over time due to wear and tear. Another potential culprit could be a faulty valve within the mixer, causing water to seep out. In such cases, it would be best to seek professional plumbing assistance to diagnose and repair the issue properly.

How can I stop my oil from leaking?

If you are experiencing an oil leak, one effective solution is to try using a sealant designed specifically for this issue. These sealants are formulated to soften and condition the deteriorated rubber seals in your vehicle, effectively stopping the leak and preventing future ones. However, it is important to note that it may take some time before the leak is fully sealed, requiring several hundred miles of driving for the additive to take full effect.
