after washing my octavia 2004 Is not starting and there is no issue found by dealer or mistri what i do 

 

Well I'd say water has found its way into some electrics somewhere! I'd start by checking connectors and the fuseboxes under the bonnet maybe....

 

Was it an Automatic wash? Or a power wash? 

Or... a hose and bucket of water job?

 

Does it happen evrey time you wash or was it a once off?

Did power return after a period of time? Or a bump start?

 

Need somemire detail... 

No problem found for a month by mistri . The car washed through personal water motor pump . Please post some detailed  article that helps me  to find fault 

 

it happens first time and no power return

What happens when you try and start? Does anything light up? Do the lights on the instrument panel come on, do the external lights work, does the radio work, what about other electronic loads? When you turn the ignition on, do you hear anything before you try and crank and while you are trying to crank. When you crank, does the situation with the lights change?

 

Did your dealer and mistri tell you what they did? If so, no point repeating what they did.

No changement takes place in lighting or any other things

So, nothing happens at all when you turn the key to any position? The whole car is dead?

Im going to presume you tried changing the battery?

It really sound like water has got into pretty important electrics, shorted everything or causing a really bad earthing.
