dishwasher was not cleaning well

I TOOK THE INSIDE PARTS ABOVE THE MOTOR APART AND TRIED TO CLEAN ALL THE CALCIUM AND MINERAL DEPOSITS THAT WERE PRVENTIN WATER FROM GETTING THROUGH. THERE WAS A LOT OF CALCIUM. MOST OF IT i WAS ABLE TO CLEAN AFTER A LOT OF SCRAPING AND SOAKING IN VINEGAR AND CLR. THE VINEGAR WAS THE MOST EFFECTIVE OF THE TWO.
i BROKE THE FILTER GUARD WHEN I TOOK IT APART. I SHOULD HAVE CHECKED ONL.INE BEFORE i START IT. THE SECONDARY FILTER ASSEMBLY WAS TO FAR GONE DUE TO MY MISHANDLNG AND HEAVY DEPOSITS INSIDE THE FILTERS. PUTTING IT BACK WITH THE NEW PARTS WAS EASY BUT I HAD TO SUBSITUTE SCREWS BECAUSE THE ORIGINAL ONES WOULD NO LONGER HOLD TWO PARTS TOGETHER. THE PARTS WERE LEAKING TO MUCH WATER. ONCE I HAD IT BACK TOGETHER THE SECOND TIME IT WORKED FINE. HOWEVER I HAD REALIZED THAT THE O-RING WAS NOT MISSING (MY BAD EYES DID NOT SEE IT IN PLACE AND SO I THOUGHT I HAD LOST IT). i EMAILED PARTS SELECT FOR A RETURN AUTHORIZATION BUT NEVER HEARD BACK FROM THEM. MAYBE I NEED TO GIVE THEM A FEW MOR DAYS. THE O-RING COST $3.76 AND MY WIFE WILL NOT BE HAPPY TIL I GET THAT BACK. PARTS SELECT DIAGRAM AND PARTS PHOTOS AND ANOTHER WEBSITE WERE A BIG HELP..
