why is my kleenmaid now leaking after I cleaned out bottom filters ?

I had help from Peccavi for my kleenmaid (super silent system DW5 dishwasher because it was not cleaning dishes at all and I did what he suggested but however now the machine is leaking and flooding the floor dripping from under neath in several places. I actually reassembled it twice to make sure everything was secure. What could be causing this now and I dont think the top arm is doing anything to wash the glasses on the top rack but not sure how to check this as it wont work until the door is closed if it does work at all. thanks again for your help guys cheers Sue
