[Grammar] This machine isn't working. It broke down this morning.

[Son Ho]

Hi teachers! Please check the two following sentences. Thanks in advance.:-D

1) This machine isn't working. It broke down this morning.
2) This machine doesn't work. It hasn’t worked for years.

 

[Tarheel]

For the second one I would say:

It hasn't worked in years.

 

[Skrej]

They're both acceptable as written.
