I have a Samsung front loading washing machine. This is the 2nd year I have owned it. I regularly clean out the filter, but lately while the clothes are being washed there is really bad funky smell that comes out of it. What is the best thing to clean the inside of it with?

I'm converting a detached garage into living space. The garage is 30' from the main house. The city requires me to connect the sewer line leaving the garage to the sewer line for the house. The main house has only one bathroom, right above the main 4" cast iron sewer line exiting the house (on the far side of the house, about 50' from the garage). The main problem is that I don't have a downward slope from the garage to the main house sewer line. I think that means I need an ejector or macerating pump of some type. I need to understand the best way to do this before I submit for a plumbing/sewer permit. I already have the building permit and have started framing. The bathroom of this garage conversion will have a toilet, shower, sink and washer/dryer. The kitchen will have a sink and dishwasher. Can all these six things go into one ejector pump basin? I like Zoeller sump pumps and notice they have some pre-assembled sewage systems that are not too expensive: [url=http://www.zoellerpumps.com/ProductByCategory.aspx?CategoryID=21]Package Systems & Basins | Zoeller Pump Company[/url] My plan is to bury one of these pre-assembled sewer ejector basin and pump systems just outside the garage building and run all six things into it and then exit the ejector pump basin and go through the foundation wall of the house into the basement, across the basement and then connect to the main 4" sewer pipe for the house. I'd really appreciate any suggestions on things I might run into here and if I'm thinking through this correctly. Thanks!
