not working correctly; defective
Not working in the right way because something is wrong with it inside.
用法パターン：
faulty [equipment/system/part]
よくある間違い：
Learners often use "broken" for any problem, even when the thing still works sometimes. Use "faulty" when something works badly or unsafely because of a defect inside, especially for machines, parts, or systems (e.g., "faulty wiring", not usually "broken wiring").
