Hi, would grateful to anyone who has a parts diagram for this dryer. The local non-profit animal shelter where my kids volunteer has asked me to replace the filter housing (I'm a guy, so they think I must be able to do this, right...?). Problem is, the filter housing won't just come out the front and it looks like the only way in is though the back panel. Sure would be nice to know what it looks like inside before I start. Thanks for any help, David.
