I had this same problem as well.  The beater was stuck like glue to the rotating arm, and it would not budge with any amount of pressure.  I tried the cooking spray and it did nothing.  But today I put a rag in hot/boiling water and then carefully wrapped it around the top of the beater.  I let it sit for 10 minutes. Then I put the rag in hot water again and repeated the process for about another 5 minutes.  When this was done, I covered the beater in a towel (to protect it) and forcefully tapped (ok... I pounded) it with the flat side of my meat tenderizer (it was all I had...you could use a mallet or hammer).  It took a little bit of work because I had to hammer it from the bottom, then the side, then the top to get the little spoke guided through the shaft.  But it did finally come off.  After cleaning with hot water, I put the beater on again and noticed that it was still a little hard to get on/off.  So, I put a little bit of veg. oil on it, and it seems to be better.  Going forward, I will be sure to clean the top of the beater & arm after each use and then coat it with a little oil to keep from sticking.  Best of luck!

Tip the machine upside down on a towel, centralise the hinge pin and tighten the grub screw that locks it into place. This is right up inside the pedestal, there is only one screw there to see.
Now stand it up and fit the mixing bowl & flat paddle, turn the machine on speed one, if the paddle is tinging on the bowl then we now need to set the head height. Turn the motor off.
Raise the motor up and from the front of the machine look in by where the motor hinges on the pedestal. You can see one screw head there. If it's tinging the bowl then you need to turn the screw anti clockwise enough so that the paddle no longer tings on the bowl.
Once it's stopped tinging put it onto max speed and make sure it still clears at high speed, if not turn the screw until it stops tinging. That's it.

You need new planetary gears in the head. Did you make a lot of bread in it, or heavy doughs? It wears them down. Contact them for professional service.

Get a round file and gently rasp it out, you are trying to remove the build up in the hole not rasp the metal away. Flour dust gets in the hole and embeds itself into the soft metal of the dough hook. Also clean the shaft if you can see any dark patches on it. The shaft is good quality steel so you can use fine sandpaper on it without really removing any metal. It's not uncommon for a paddle or a hook to become frozen onto the shaft from flour dust getting in there while mixing. The first time I encountered it I had trouble convincing myself the flour was the problem, I've seen enough of them now to know that's what it is.

If it is the worm gear then the planetary will stop turning when there is a load on the paddle but the motor will continue to run at the speed you set it at. I'd be checking the carbon brushes, checking that the field assembly has not loosened up a bit and then I would see if the speed control plate adjustment screws are loose. I'd then reset the speed and see if it stays as it should be.

Replace the motor.

KitchenAid K45SS... | Answered on Aug 19, 2017

There are lots of places to be looking, first thing I would look at would be under the rear cover to make sure the two nuts that hold the rear motor bearing housing in place are nipped up. You don't wring the neck on these nuts, if you over tighten them you will deform the rear bearing housing.
If you can find someone local who has been doing these mixers for a while they will be able to give it a once over. It's unlikely to be expensive. Best people to ask is Kitchen Aid, they should know who does their warranty work in your area. If you are in new Zealand it will be me.

You need to take the back cover off and then split the gear cases to find the mechanical reason why the lever is stuck. Take the motor off the pedestal, remove the planetary and undo the 9 screws that hold the bottom gearcase to the top housing. You will need to unplug the white and the black wires from one side of the speed control plate.

The trim ring news to be ta]ed in place with a plastic-face mallet. This type of mallet does not (if used properly) Mar the surface it striks.

Hold the trim ring in place while tapping it in place. It often takes patience to get it right.

The ring is properly in place when there is no place where you can insert a fingernail between it and the mixer body all around the ring.

Kitchenaid does not recommend using a US model mixer overseas since the frequency is different. Here in the States we use 120 Volts 60 Hertz, it Europe they use 240 Volts 50 Hertz so even if you were to feed it the correct voltage, the frequency would still be lower and the mixer would run slower and hotter causing shortened life of overheating.

Hello Heather,

Either the grooves on the bowl lock plate are worn out, or the grooves on the actual bowl are worn out. I would start with replacing the bowl lock plate. Here is a link to the part: KitchenAid Mixer Bowl Lock Plate 4163032

This part is really easy to replace, it is held into place with three screws, remove those screws (make sure to hang onto those you will need them to re-install the new part). then you should be able to pop the old plate out. To install the new plate like up the screw holes, and press into place, sometimes you need to lightly tap it into place with a rubber mallet as it is suppose to be a very tight fit.

Once that has been replaced your bowl should lock into place tightly. However there is always a chance that the bowl has been worn down and may need to be replaced. Here is a link to the 4.5 Quart bowl: KitchenAid 4 5 Quart Stainless Steel Bowl

That surely can't be the model number if it looks anything like the photo. If it's a model number it should Google and it doesn't.

There are a few parts that make up the speed control mechanism, the selector can only be the knob and lever. That moves the speed control plate which is the ********* square thing under the back cap that tilts when the lever is operated. There is a governor on the end of the armature under that control plate, that governs the speed by cutting the power through a circuit to maintain an even speed. Above the black control plate is a PCB (phase board I think they call it) that along with the other bits & pieces regulates the power to the control plate.

If the motor itself is slowing down, that is one thing. However, if you mean by "dog" that there is what sounds as if a gear is slipping then the solution is straight forward. The worm (follower) gear needs to be replaced.

There are videos on the net which show how to do this and the Service Manual can be found at:


KitchenAid K45SS... | Answered on Oct 02, 2016

If it slows down when mixing, it is most likely that the mixer is being asked to do more than it is capable of. If it slows down when nothing is in the bowl, then the motor/gears/lubrication needs looking after.

The Service Manual is at:


KitchenAid K45SS... | Answered on Oct 02, 2016

This can be caused by a number of things. Offhand, some are:

Bad line cord.
Worn brushes.
Faulty phase board.
Faulty control plate.

In any case, the Service Manual can be found at:
