I posted yesterday re: why dishwasher would not start. After disassembling the machine and cleaning out tons of gunk and impacted glass fragments, plastic tags, etc, I am puzzled about how to reassemble the lower wash arm. I cannot figure out how to reattach it to the water supply. There just doesn't seem to be adequate clearance to get the two pieces back together again. Please help as it is the only step left to reassembling and testing. Thanks!
