Purchased the PDT755SYVFS diswasher and on the first wash, set at the normal settings,  the washer took forever to finish... AND, the dishes were still wet!  We tried the 1hr. cycle for the second  load and added the heat boost, which increased the total time to almost 2hr.  Towards the end of the wash lots of condensation formed on the top panel of the maching and started running down onto the hardwood floor!  Called the serviceman and he said there was a "tech bulletin" for the particular problem.  The fix turned out to be a tube of caulking which he applied.  That seems to have solved the problem and besides the length of time it takes to wash it is now working ok.
Question?  Does GE ever test these machines before offering them for sale?  Had serveral issues with the GE frig we purchased at the same time.  Seems quality control is almost non existant anymore.
