Stand Mixer Repair 201: Why is My Stand Mixer Leaking Oil

If you've noticed oil leaking from your stand mixer, several factors might be at play, affecting its performance and longevity. Understanding the causes and remedies can help you maintain your appliance effectively.

Idle Periods and Overheating

When a stand mixer stays idle for extended periods, experiences overheating during use, or encounters permanent decomposition of grease in the gearbox, oil separation can occur, leading to leaks from the mixer shaft. To prevent this, it's crucial to use the mixer regularly. Regular use helps in avoiding the separation of oil and grease, which could otherwise leak along the mixer shaft.

Preventive Measures

If your stand mixer has been unused for a month or more, consider running it on the highest speed for at least 2 minutes before actual usage. This process effectively remixes the separated oil and grease, preventing leaks during subsequent operation. Use a pouring shield or a protective towel to minimize potential oil splashes while remixing. After the 2-minute run, inspect the mixer, wiping off any oil along the shaft or in the bowl.

Heat-Related Leaks

Continuous operation for more than 30 minutes can cause oil to leak down the beater shaft due to grease overheating. In such cases, it's essential to halt the mixer, allowing it to cool before resuming use. If oil continues to leak during constant, heavy use, it might indicate a need to change the grease. Consider replacing it with food-grade grease designed for stand mixers.

Persistent Oil Leaks

For those who regularly use the mixer and experience frequent oil leaks even during light operation, changing the grease becomes imperative. The oil may have permanently separated from the grease, necessitating a switch to stand mixer food-grade grease for optimal performance.
