Constantino, why don't you take another careful look at the examples for 1st, 2nd and 3rd conditionals which I gave you a short while ago, and try to correct these sentences yourself?
The third sentence about the dishwasher is fine, but the conditional sentences are wrong because you didn't follow the formulae I gave you. Here's an example of a 3rd conditional:
'If you had followed the formulae carefully, you would have written some correct sentences.'
Why not try writing these sentences again, using the correct sequence of tenses?
