The initial sound you get after selecting a program will be the drain pump removing any water present, before then letting in water.
After the 5 seconds do you still get a wiring sound, or does it go silent? When you open it do you see any water in the sump where the water sits?
It sounds most likely there is an issue with the inlet valve, can you confirm you have check the supply pipe isnt kinked and the water service valve hasnt been shut off in error?
Good morning do you still require assistance?
I havent heard back from you in a while, do you still require assistance?
