I have a Kitchenaid 550 watt 6 qt. stand mixer model #KB26GIXER. I tried to use it this morning and couldn't get the beater blade to lock in place. Isn't there supposed to be a spring and washer above the locking pin? (They seem to be missing.)

Buy a new one quick. Or hide. Spent . electrical engineering. And supply of new diodes resistors and capacitors are needed.

Check different outlet. Make sure the outlet isn't at fault.

The clicking is probably a small nick in one of the gears, even the smallest chip can cause alot of noise or make the mixer click. Is the beater shaft still turning when you have a load in the mixer (bowl is full)
Or is it just clicking?

If the beater stops turning it is going to be caused by stripped gears, however if it is just clicking this would indicate just a nick in the gear. Either way I would recommend opening the mixer and replacing the damaged gear/gears.

Your mixer is considered a 5 Quart Professional, which means it has the same parts as a KitchenAid 6 quart mixer. The first thing you will want to do is take the mixer apart and disassemble the gearing. You will want to clean off the gears with paper towels and wd-40. Carefully inspect each gear once clean and replace damaged gears.

In the professional mixers when a gear strips you need to replace the grease and housing gasket, this is because the gears are all metal and there may be metal shavings in the grease which could cause the gears to strip again.

The most common gear to go bad in the Professional series mixers is the Worm Follower Gear (9706529). Here is a link to that gear on our website: http://www.mendingshed.com/wormfollower.html

Also, here is a link to the service manual for the mixer, this will aid you in taking the mixer apart and putting it back together correctly. http://lib.store.yahoo.net/lib/mendingshed/kitchenaid6qtservicemanual.pdf

You can adjust the mixer bowl up and down slightly. If you lower your bowl and look at the back you will see a little screw, it looks like a flat head screw and it is on the "neck" of the mixer.
You can raise and lower the bowl by adjusting this cam screw. You can tell that your bowl is adjust correctly by attaching the flat beater and put a dime in the bottom of the bowl, the beater should just barely touch the dime and move it around the bottom of the bowl.

The beater will not scrape the sides of the bowl, if you are wanting the sides of the bowl scraped I would recommend the Flex Edge Beater made by KitchenAid which is basically a flat beater with a rubberized edge which will scrape the side of the bowl as it rotates.

Here is a link to the flex edge beater on our website: http://www.mendingshed.com/kfe6l.html
Let me know if you have any other questions.

Make sure your Beater can slip in and out of the Beater Shaft
easily. Do not force the beater onto the Shaft if the shaft is bent.
If it cannot be removed easily by hand, use a soft rubber mallet
(not a steel hammer) to slightly tap the beater so it can be moved
up and down the shaft or from side to side. Then you can easily
turn the beater left and remove it from the shaft.

From Kitchenaid Manual:
To Attach Flat Beater, Wire Whip, or Dough Hook
1. Turn speed control to OFF.
2. Unplug stand mixer or disconnect power.
3. Tilt motor head back.
4. Slip beater onto beater shaft and press upward
as far as possible.
5. Turn beater to right, hooking beater over pin on shaft.
6. Plug into a grounded 3 prong outlet.

To Remove Flat Beater, Wire Whip or Dough Hook

1. Unplug stand mixer.
2. Place bowl lift handle in down position.
3. Attach flat beater.
4. Adjust so flat beater just clears bottom surface of bowl
when in lifted position by turning screw
(A) Counterclockwise to lower the bowl.
5. Just a slight turn 90 degrees in either direction.
Place bowl lift handle in up position to check clearance.
6. Repeat Steps 4 and 5 if necessary.
I hope I helped you.

Hi KELLYSERMAN, this should be pretty easy to do by yourself the instructions for adjusting your beater to bowl clearance is in your Owners Manual. I you don’t have the original manual you can easily download a PDF version of your Owners Manual from the KA website: (http://www.kitchenaid.com/flash.cmd?/#/page/home).
Click on Customer Care>Locate Manuals& Guides> and enter the 6 character model number, in your case KSM150 and select the file listed for your model that appears under Owners Manuals (66): KSM150PSER1 (732.33KB) and save that file to your PC. Turn to Page 14 and you will find the instructions for adjusting the mixer head height. I have extracted the instructions below:
Beater to Bowl Clearance
Your mixer is adjusted at the factory so that the flat beater just clears the bottom of the bowl. If for any reason, the flat beater hits the bottom of the bowl or is too far away from the bowl, clearance
Tilt-Head models
• Unplug mixer.
• Lift motor head.

• Turn screw (A) SLIGHTLY counter clockwise (left) to raise flat beater or clockwise (right) to lower flat beater.
• Make adjustment with flat beater, so it just clears surface of bowl.
If you over adjust the screw, the bowl lock lever may not lock into place.
I hope this helps! – Howard, Burke, VA

you need to lift the beater then twist it will come off i have the same mixer thanks from gilles

The height of the beater is easy to adjust on the tilt-head model.  Tilt the head back, and look into the pivot from the front of the mixer.  You should see a screw on the hinge.  With a flat blade screwdriver, rotate this screw half a turn counter-clockwise to raise the beater height.  Lower the head and check that the beater does not touch the bowl.  Repeat until the adjustment is satisfactory.  To lower the beater closer to the bowl, turn the screw clockwise instead.
