Dish washer won't start wash cycle

Hi there, I’m new to this forum game so excuse me if I’m not using the correct lingo.
I’m in need of some help and advice. If i can’t find an answer then its payout time for a new dishwasher:mad: .When i start the dishwasher(on any cycle) the drain pump kicks in as it should then the water should enter the machine. It never happens, and then the machine beeps and lights 4 &5 flash (fast wash &pre wash). I have checked that the water is coming into the machine with no kinks in any pipe work, cleaned all filters, replaced the water inlet valve and the drain pump with brand new items yet still nothing:confused: :confused: :confused:
Can any body help me coz I ain’t paying hotpoints £100 call out fee!!!
Cheers in advance:)

Unfortunately it is very hard to find any on-line information for non American models.
