Tells me may be a different issue, the smell usually is not from the unit itself it is from the waste water filter back into the unit at the end of the cycle. Look at your drain hose and make sure it is in a high loop. It must loop higher than where it connects to the drain like a roller coaster or waste water will siphon back in at the end of the cycle. I would run a cycle of distilled vinegar as well once a month to keep bacteria out too.
