Continues to leak even after fixed 3 times.

Our Whirlpool Duet washer has been a problem.  We had so many leaks in the past on all over the ceramic and wooden floors.  We had extended warranty but they would come & do a quick fix but later on it would leak again.  We still have warranty, they found out that there was a hole in the boot.  The boot was replaced it but still the problem occurred. Now they are saying that the tub is sitting faulty, the gap between the tub and front is not same on the top and bottom and is too much.   It sits faulty and that is the reason it may have a problem.  We have not been to wash for months now.  I believe buying the Whirlpool was a mistake.  It is a costly machine but it has given us nothing but problems.
