Yes, that’s a much better answer. Your original answer was:
Try to recreate the problem, check the water inlet valve to see if the valve is sticking
You got 50% because you did identify the valve as needing to be checked, but didn’t talk about what measurement you would make, which is critical.
Recreating the problem is an important thing to do before beginning troubleshooting, but it’s not a troubleshooting technique.
NOTE: I’m going to hide the question in your post to make sure it doesn’t just give other students the answer.
