Hello, to who it may concern,

I am using 915 D2, which was bought last year.

Since there was some dirt and marks on the head, last weekend I cleaned my driver.

putting the head in the warm water and then taking it out and then clean with dry towel.

But one thing I found is that I could hear some sound like air-leaking, which seems to me water leaks in the head.

So, my questions are:

1. What does this sounds mean? 2. Is this normal(no problem) in terms of function 1or otherwise does it indicate the fault on the head?

If everything was tight, I don't understand how the weak points are to allow moisture to get in.

3. If water leaks in or the sound indicate some fault, what should I do? Should I go to the shop and request the change under the warranty? or just let the shop check and confirm this is no problem?

For your reference, I attach one photo, where I could hear the sound.

Please help!
