Modern machines have a warranty, as stated above. You open the machine without proper certification , you void it. Simple as that. It's best to have a service manual if you want to tinker. That's why so many people love the more simplistic, mechanicals and vintage machines. They can easily be maintained and serviced, saving you a ton of money over its life time.
