SERVICE TEST waterproof error & speaker sounds bad after waterproof

[Jras87]

Good morning, my Xperia Z sounds bad after waterproof, not always but sometimes...

And I can see with the service code, calling  *#*#7378423#*#*

Appear a screen ans select the options -> SERVICE TEST

aND SELECT WATER PROOF ->      and the result is that...

Can anyone explain to me why?

Everything are working but the WATER PROOF test say this...

- the waterproof test is not functional. i don't think there is a built in funtion for this test.

- the low volume is normal because the speaker vent is covered/filled with water. sound cannot travel because it's been blocked. when the water in the speaker vent has dried, sound will return to normal.
