If the mixer was purchased from us, we will assist with repairs and getting you in contact with the right service department for your mixer brand. If you didnt purchase it from us and it is not a brand we carry, we may or may not be able to assist, depending what is broken.
If the mixer not working at all, it might be an electrical issue. If so, most electricians can fix it. If the issue is mechanical, like the gears have stripped or motor is spinning but hook is not, then it will be best to contact the manufacturer of your mixer as you may need replacement parts.
If you cannot contact the original manufacturer, we suggest to search online for planetary mixer repairs in your area
