I bought a LM900 along with the LitterWorks combo online in February. The Littermaid LM900 worked fine the first few months, in the past month the rake keeps on getting stuck and won't finish the cycle. I contacted LitterMaid Warranty and they said I have to give them a date code, even though I have a copy of my invoice. My date code was scratched from the machine. They won't assist me unless I can identify the date code. I can only make out a "3 or 8" and what looks like an "E" out of the what looks like 3 or 4 digit date code on the battery department. Does someone own a LM900 that was manufactured over the 1 and 1/2 year or so? Can you please tell me what the date code is? I really want to get my littermaid working again since I spent so much on the Litterworks combo
