Why does my mixer not turn on until I place it on the highest speeds?

I am not happy with my mixer. First off, it cost a lot of money. Second, the top does not tilt backwards which makes adding ingredients very difficult. Over the years, I’ve gotten used to that only because I don’t use it a ton (usually only around the holidays). Now the problem is it will not turn on until I set it to the highest speed and I boy, that makes quite the mess especially with wet ingredients. It will go to normal speed once I turn it back down. I have switched places on my counter to try different outlets and that’s not working. Any idea what could be wrong? I have had the mixer for several years but as said earlier, I’m not using it a lot so I don’t understand what happened?
