Why Does My KitchenAid Mixer Leak Oil

Why does my kitchenaid mixer leak oil? Stop beating yourself over this problem because we have the answer, and we’re going to tell you how to fix it.

Your KitchenAid mixer might leak oil because of overheating, overuse, mismanagement, or generally high temperatures.

It shouldn’t stop you from using your stand mixer, right? Yeah, that’s the spirit!

To fix a mixer that leaks oil, you’ll need to take the machine apart one by one.

It’s a ten-step-long (Although easy!) process, and we can’t wait to show you how it’s done.

As long as you have a flathead screwdriver and a knife, you can fix your kitchen stand mixer all by yourself!

Before your KitchenAid mixer claims the second-largest oil spill in history, let’s fix it, shall we?

5 Common Reasons Why Your KitchenAid Mixer is Leaking Oil

It’s not uncommon for any mixer to leak oil. For now, we can think about five reasons why your KitchenAid mixer might be leaking oil and from where.

  • Overloading the Mixer

The oil keeps the gears well-lubricated during use. All KitchenAid mixers come with years’ worth of gear oil. But overloading can use up more oil than usual, dripping a few drops of oil here and there in the process.

  • Infrequent Use

Using your stand mixer infrequently can play out in two ways- the grease can either harden up or melt through the drip ring.

  • Hot and Humid Conditions

Your KitchenAid stand mixer is not the most weatherproof of all appliances. High temperatures and humidity can affect its internal gear, causing the mixer to leak oil.

  • Problems in the Planetary Cover

The planetary cover is what separates the main gearbox from the outside.

Nearly all the oil is inside the gearbox. Five screws secure the planetary cover to the housing. So, if the mixer is leaking oil, check the screws and the pin.

  • A Loose Drip Ring

The drip ring or the beauty ring is supposed to catch the leaking oil in the first place. If oil is leaking from the planetary and dripping down the beater, you need to look at the beauty ring.

Identify Where Your Stand Mixer Is Leaking from

Check if the location of the leak matches the ones we’ve stated below! Then, we can move on to the repairs.

  • Grease dripping off the beater
  • You see oil pooling below the rear part of the stand mixer
  • Oil is coming out of the Speed Control Buttons

The last one is likely a handling problem during the shipping.

How to Fix a KitchenAid Mixer that Leaks Oil?

If your KitchenAid mixer is leaking all over the place, don’t panic.

We’ll tell you how to fix your leaking KitchenAid mixer at home. Keep reading!
A point to note- the following repair process applies to all professional KitchenAid mixer models whose numbers begin with KSM, K45, or K5.

These are all the things you’ll need to get started.

  • A flathead screwdriver
  • KitchenAid stand mixer grease (Only if you hear a grinding sound)

After taking off the rear housing cover with a screwdriver, you can remove the cord strain relief.

Step 2: Detach the Beauty Ring and the Planetary Pin

The beauty ring will come off after a few rounds of gentle prying. Next, you’ll notice that a pin holds the planetary to the gearbox. Gently tap its head with the screwdriver, and it should come through the other side.

Step 3: Take the Planetary off and Remove the Screws

Pry open the planetary to reveal five gearbox screws. Unscrew them first and then move on to the four screws at the back. Take note of the retaining washer, as in which rear housing screw has it.

Step 4: Disengage the Motor Housing from the Stand

Lift the motor housing off the mixer stand. The gearbox should stay face-up at this point.

Step 5: Scoop Out the Old Grease with a Knife

Now, it’s time to put that putty knife to use. Carefully scoop the old, sticky oil from the gearbox.

Step 6: Apply the New Gear Oil to the Gears

Replace the old grease with the same amount of KitchenAid Stand Mixer Oil. Use a clean knife this time.

Step 7: Seat the Motor Housing on the Stand

Your work is almost finished!

From this step on, you’ll be doing precisely the opposite of what you’ve done so far.

Begin with clamping the motor housing on the stand.

Step 8: Screw All the Fasteners Back to Their Slots

You must screw all nine of the screws you’ve taken apart from the rear motor housing and the planetary.

Remember to put the lock washer in the exact same place.

Step 9: Attach the Planetary Pin and the Drip Ring

You might find wedging the pin back inside the hole a bit difficult.

All the planetary gears need to be aligned. So, it’s a good idea to lubricate their edges first slightly. Attach everything the same way you took them off.

Step 10: Clamp the Rear Housing Cover Back on

Before you get to the rear housing cover, don’t forget to clamp the drip-catcher ring around the planetary.

Be gentle and careful.

Finish by placing the rear housing at the back of your mixer. Replace the power cord’s strain relief, and there you have it!

This is how you can repair your KitchenAid mixer without damaging anything.

Trust us on this- these will minimize and even stop the leaks right away.

  • Turn up the Speed Level

Did your KitchenAid stand mixer sit unused on the countertop for months?

Then you can turn it on and let it run for two minutes at medium to high speeds.

  • Allow the Mixer to Cool Off

If you use your stand mixer often during the day, you should give it a few minutes to rest in between.

Otherwise, it could overheat the gears and liquidize the solid grease too fast.

Allow all your appliances some time to cool off before you can use them again.
