Identify the Source of the Leak
- Unplug the mixer and move it to a clean workspace.
- Remove the tilt-head lock and gently lift the head to access the internal components.
- Inspect the area around the gear housing, drive shaft, and bowl hub for visible oil or grease leaks.
- Check if the oil is coming from the gear box, seals, or other internal parts.
- Note the exact location of the leak for targeted repairs.
Disassemble the Mixer Carefully
- Use a screwdriver to remove the screws securing the top cover or gear housing, following the manufacturer’s guide.
- Gently lift off the cover, taking care not to damage any internal components.
- Inspect the internal seals, gaskets, and oil levels.
- If you notice cracked or worn seals, these are likely the cause of the leak.
Replace Worn or Damaged Seals
Identify the seals or gaskets that appear damaged or worn out. You can order replacement seals from KitchenAid or authorized parts suppliers. Carefully remove the old seals using a small flat-head screwdriver or seal removal tool. Lubricate the new seals lightly with food-grade silicone grease, if recommended, and install them securely. Reassemble the gear housing, ensuring all screws are tightened properly.
Reassemble and Test the Mixer
- Reattach the top cover or gear housing, tightening all screws firmly but not excessively to avoid damage.
- Lower the tilt-head and lock it in place.
- Plug in the mixer and run it at low speed to check for leaks.
- Observe the area around the gear housing and bowl hub for any signs of oil escaping.
- If no leaks are present, gradually increase speed and test with ingredients to ensure proper operation.
Tips and Warnings for Ongoing Maintenance
- Regularly inspect seals and gaskets for wear and replace as needed.
- Keep the mixer clean and free of dust and debris that can damage seals.
- Always unplug before disassembling or cleaning internal parts.
- If your mixer continues to leak after replacing seals, consult a professional.
- Use genuine replacement parts to ensure compatibility and safety.
