Step 2: Access the Gear Housing
To locate the source of the leak, you need to open the gear housing. Use a Phillips screwdriver to remove the screws around the base of the mixer’s head, carefully lifting the top cover. Be cautious not to damage the wiring or internal parts.
Once open, inspect the gear housing for signs of oil seepage or damage. Wipe away excess oil with a clean cloth to see where fresh leaks might be occurring.
Step 3: Inspect and Replace Seals
- Identify the rubber seals or gaskets inside the gear housing. These are designed to keep oil contained.
- If seals are cracked, hardened, or missing, replace them with new ones compatible with your model.
- Apply a small amount of food-grade or manufacturer-recommended lubricant if advised, but generally seals should be dry and tight.
Step 4: Reassemble and Test
- Carefully reattach the gear housing cover, ensuring all screws are tightened evenly to prevent future leaks.
- Plug in the mixer and run it at low speed without any attachments to check for leaks.
- Observe the gear housing and attachment hub for signs of oil seepage during operation.
Tips and Warnings for Safe and Effective Repair
- Always unplug your mixer before opening or working inside it to avoid electric shock.
- Handle internal parts gently to avoid damaging delicate components.
- Use only manufacturer-approved seals and parts to ensure compatibility and safety.
- If you’re uncomfortable with disassembly or if the leak persists after replacing seals, contact a professional technician or KitchenAid support.
