My max 325 Kitchenaid Artisan Mixer was leaking oil and was making a grinding noise in all speeds it made a loud pop sound and now it won't do nothing. What is the problem?

If it is leaking you are going to have to go inside the gearbox to change the grease so whatever is wrong inside may become obvious when you take it apart. Remove accessory cap from the front and look for any dryish grindings inside there.

A bunch of things could be wrong.

The Service Manual below does not specifically reference the Artisan Series but the motors and service details are the same:

It sounds like two issues, the first is going to be the phase board, you will need to replace it, that should fix your speed issue.

The second issue will be a stripped gear, in that mixer there is a nylon gear that commonly goes bad, that would be the worm gear.

Here is a link to the phase board: http://www.mendingshed.com/kaphaseboard.html

The service manual will show you how to take apart the mixer, and put it back together.

Try a different Receptacle outlet if it trips that breaker you know its the mixer, and there will prob be a short/loose connection somewhere

Your guess is correct. Get it cheap on Ebay.

Kitchenaid mixer are supposed to make a slight grinding sound while operating under load. This is simply the gears meshing together while the motor is turning them, but if the sounds gets worse or is already a metal grind type sound this could indicate a broken worm gear inside the unit, and shouldn't be run any longer. However if your mixer isnt on SOLID ground this could cause the tremble as well.Hope this helps

Thanks

It very likely sounds like a plastic gear that is worn. If this is the case, then a replacement is very likely stocked by the manufacturer only.

I advise opening the unit to identify which one you need, then 'phone the manufacturer with the make model and year of the product.

If they say they do not stock it - then I'm afraid that's as far as you can go with this.

Leaking of oil in a stand mixer is not necessarily indicative of a large problem.

Kitchenaid stand mixers are overpacked with oil to last the lifetime of the motor. If the motor sits idle for some time (is not used), the oil may begin to drip from the gears and settle. Oil leakage may primarily be seen from around the beater shaft or planetary action.

A stand mixer can lose up to a 1/4 cup of oil before it needs to be serviced.

It is recommended to run the mixer on speed 10 for 2 minutes in order to redistribute oil back into the motor. In order to prevent future occurences, this is recommended to be done every 3 weeks if mixer is not being used.

Hi. These mixers normaly make a lot of noise when in operation. Go to the shop that sold it to you, or any place that has these units on display and ask them to turn on the mixer for a demonstration. If their mixer does not make the same noise, then contact Kitchenaid Customer Service and ask for a replacement under warranty. If this solution assists you, please rate it. Good luck! ricardok45

The repair manual says that the mixer can make this grinding sound at slow speed, like stir or 2. This is normal, especially until it warms up. This is the sound of the gears turning at slow speed.
