The activator buttons are stuck

Spray some WD40 into the eject button. The wait 10 minutes and turn it upside down and spray WD40 down the side of the beaters Leave 10 minutes and try again/ If that doesn't work, you will need full disassembly

..

Instructions say to "press" (push in) the head tilt button. If the button wont move, try moving head up and down while applying pressure to the button.

The safety switch activated or damage

You will most likely have to take this apart to get it out again. Over all not really that hard.....about 6 screws to get the top off. If you don't want to go that route the only suggestion I have is to get a really strong magnet and try to manipulate it out with that.

Look for a stuck relay or contactor that is siezed closed.

I dont think the button is the problem.I suspect the side switch on the contactor is bad.Give me a little more info like when the problem started.

Sounds to me like the start switch contacts are welded shut.If you have a multimeter set it to ohms,remove 1 wire from the switch,put your meter leads across the switch and if you get a reading that switch is bad.If you dont get a reading i would check the side switch on the contactor.Im a hobartt tech and repair these mixers alot.Let me know.

Unplug power cord. Plug back power and keep pressing the eject button repeatedly while the unit starts up. Do this a couple of times, if you succeed in activating the eject before the system starts reading the disk, then it will eject.

If you do not get the disk out in this way, the only alternative is taking the unit apart, and removing disk from inside manually.

dont put gift card info on the internet please. if those cards were active someone could do online purchases just like a credit card.

You will have to have the transmission serviced. sounds like the gears were ground out. you can do the service work yourself its not to difficult.
