Identify the Source of the Leak
Before attempting any repairs, determine where the oil is leaking from. Common areas include the gear housing, the attachment hub, or the tilt-head mechanism. In my testing, a visible oil spot near the base of the mixer or around the tilt-head joint indicates a leak.
Make sure the mixer is unplugged and placed on a stable surface. Carefully tilt the head back to inspect the internal components. If you notice oil pooling or seeping from seals or gaskets, this confirms the source of the leak.

Gather Necessary Tools and Parts
You will need a few basic tools: screwdrivers (Phillips and flat-head), a clean cloth, and possibly a replacement seal or gasket specific to the KitchenAid Artisan Series (refer to your model number and parts list). It’s advisable to have a small container or tray to hold screws and small parts during disassembly.
Ensure you have the correct replacement parts, which can be ordered from authorized suppliers or directly from KitchenAid. Using original parts ensures compatibility and safety.
Disassemble the Mixer to Access the Seals
- Unplug the mixer and remove the attachment hub cover. Use a screwdriver to loosen screws if necessary.
- Carefully tilt the mixer head back and locate the gear housing and seals. Depending on your model, you may need to remove the top or bottom panels to access internal components.
- Gently disconnect the seals or gaskets that are leaking. Take care not to damage other parts during removal.
Replace or Re-Lubricate Seals
If the seals are worn or damaged, replace them with new ones designed for your model. Apply a small amount of food-grade lubricant if recommended, especially around the new seals, to ensure a proper seal and smooth operation.
In my experience, replacing the seals is straightforward if you follow the manufacturer’s instructions and use the correct parts. Make sure the seals fit snugly and are seated properly to prevent future leaks.
Reassemble and Test the Mixer
Once the seals are replaced, reassemble the mixer in reverse order. Tighten all screws securely but avoid overtightening, which can damage parts.
Plug in the mixer and run it at various speeds to check for leaks. Keep an eye on the repaired area for a few minutes of operation. If no oil appears, the fix has been successful. If leaks persist, review your assembly or consider professional service.
Tips, Warnings, and Preventative Maintenance
- Always unplug the mixer before disassembly or inspection to prevent electrical shock or injury.
- Handle internal components gently to avoid damage, especially gears and seals.
- Periodically check for oil leaks or unusual noises, which may indicate worn seals or other issues.
- If unsure about any step, consult a professional repair technician or contact KitchenAid support.
- Use only manufacturer-approved replacement parts to ensure safety and compatibility.
