Common Causes of Oil Leaking in Your KitchenAid Mixer
Oil leaks in your KitchenAid Artisan mixer are typically caused by worn or damaged internal seals, especially around the gear housing or the transmission area. Over time, these seals can degrade due to age, misuse, or cleaning with improper solvents. Other causes might include over-lubrication or accidental damage during cleaning or maintenance.
Understanding the root cause is essential before attempting repairs. In most cases, the leak is from the gear case or the transmission housing, which contains lubricating oil necessary for smooth operation. If this oil escapes, it can cause messes, attract dirt, and impair the mixer’s functionality.
