You need the Service Manual which shows how to adjust the speed. You will be working in the vicinity of live 120 volts if you do this. Be very careful. You can download the Service Manual from:

The screw which can be seen at the pivot when you tilt the head back needs adjusting. Turn it counterclockwise a bit at a time until the beater no longer hits the bowl.
your mixer has a specific wattage that it is rated for, If the mixer trips the breaker at your panel try using another outlet in your house to make sure that it is the mixer and not the outlet socket. Then you need to try your brushes depending on age and use of the mixer they may be exhausted and a higher wattage draw may be causing the breaker to trip, if the brushes have at least 3/8th inch of black carbon left on them then sadly it is the motor, you probably need a new armature or a new winding or both, which would be a complete motor at that point. If it is the motor parts then the repair will require a FULL tear down at which time you may as well clean it up completely and add new gear grease and a new motor gasket while you are at it. .
Unfortunately this model is not sold here so my advice can only be general advice. Over voltage will normally blow a PCB before the fuse has a chance to blow so you should be investigating that part first before looking for a fuse it may not have. It is only going to be fixed by an appliance repair technician, preferably one authorised by Kitchen Aid. As a rule I would not expect the PCB to be repairable after double over voltage. It is probably going to need for it to be replaced. Now is probably a good time to enquire with your Kitchen Aid repairman to see if conversion to your UK voltage is economic or possible as money is going to have to be spent anyway.
There ate two ways to fix this problem, but first there is the matter of understanding what is leaking. The oil you see leaking is actually a food safe vegetable based gear grease. The grease separates during heavy use (years of service) or when the mixer has not been used for an extended period of time. (months or years) The recommended way to fix the problem is to do a full tear down then clean then add new grease and a new gasket, cost (By Kitchenaid at a KA service center) around $140.00 US + or -, It involves shipping and around ten days in time. The second way is kinda simple and does not cost anything. Get a towel, thick and soft to protect your finish, get your wife or husband, get an extension cord, spread the towel out on an open counter top, plug the extension cord into the outlet, turn the mixer upside down on the towel, have your significant other hold the mixer by the base while you plug the mixer cord into the extension cord, turn on the mixer no more than 2 or the second click on the speed control switch / lever, hold the mixer upside down like this while the mixer is running and keep it running for at least three (3) minutes, turn the mixer off and turn it right side up and turn on again for two minutes, then do it again two or three more times, upside down for a couple minutes then back right side up and so on and so on, after about 15 minutes stop. put everything away, you are done. What you have effectively done is re-mix the grease and it should be good for another couple of years. When it starts to leak again re-mix again. Or send it to KA for the rare and unique opportunity to spend a hundred bucks that you don't' want. hope this helps. By the way if you get some drops in your mix it will not hurt anybody. But you do not want to eat a great deal of it or you will require the use of a laxative afterwards.
Sounds like the worm gear was stripped. This gear is designed to fail when the load on the motor is too great. This protects the motor from overheating and burning out. By the way, the mixer should not be used above the number 2 speed when using the dough hook.
The worm gear is not all that hard to replace although you will have to contend with a lot of grease. See the Service Manual:
http://www.kitchenaidparts.eu/documents/pdf/service-manual/classic-svc-manual-new-email-version.pdf
These are two separate problems.
The beater is probably being held on by dried/solidified flour. Try keeping the section where the beater joins the mixer head wet with water to loosen up the dried "glue." (Give it some time.)
The oil leak is caused by the grease separating. You can try running the mixer on high for a few minutes to re-mix the grease. If this does not correct things, you will need to clean out the old grease from the gearcase and replace it with new. See the Service Manual at:
http://www.kitchenaidparts.eu/documents/pdf/service-manual/classic-svc-manual-new-email-version.pdf
Check the motor carbon brushes, remove the back cover and check for broken or disconnected wires. Using a multi meter check the main cable for continuity from wall plug to the speed control board. That will be the black wire and the white wire at the bottom on one side of the control plate. After that check fields for continuity, that will be between the 2 wires on the bottom on the other side of the control plate and the brass insert inside the brush holders. One of the wires will be a circuit through the fields to one of the brush holders.
It is likely to be one of two things, Too much friction in one of the gear or motor bushes or a faulty motor armature. Put it on high and switch it off at the wall, if it seems to stop rather quickly then look for a binding bush. If it stops over several planetary revolutions then I'd be looking at the motor. A Kitchen Aid service person will easily be able to sort it out for you.
Unfortunately, this not an uncommon problem.
There is some substance "gluing" the beater in place. Try using some rubbing alcohol where the shaft enters the beater and letting it soak for a while, adding more as necessary.
If this does not loosen it up, the next step is to go to a penetrating oil and seeing it it works better.
When your stand mixer does not turn on the problem might be a lack of electrical power, broken wires or a failed motor or control problems. First, check the outlet's GCFI breaker and reset it if it's tripped. If the mixer still won't work when plugged into a working electrical outlet then unplug the mixer and check the power cord.
Hiya,
I am sorry to hear you are having problems with your mixer. To stop the oil leaking from the front of the mixer, you just need to remove the drip ring and give it a good clean underneath and this should stop the oil from leaking out. Below I have added a link and if you watch on the timing "1.28" you will see how to remove the drip ring.

I hope this helps!
When your mixer is not starting , you could have a motor that has overheated as the mixer motor is thermally protected. An electrical problems such as a reset GFCI outlet or electrical breaker may also be causing the problem.
The manual recommends turning off the mixer and also waiting for about 10 or 15 seconds, and turning it back on. If the mixer still will not run, wait for 30 minutes before trying again. The unit does not have a reset button, so if it still doesn't operate after a 30-minute wait, you'll have to look elsewhere for the problem.

Hiya,
I am sorry to hear you are having problems with your beater not turning.
The problem may be that you have damaged the Worm Gear inside your mixer. I have added a link below for a help video on replacing your worm gear:

I hope this helps you :)
