    Pull out the top drawer and push up the stove top.
    It’s just Velcro in place. Have a look at the water connections under there......should be bone dry.

    Here is a couple of pics if helpful; these are behind the refer but for a 400DA which may be similar. There are multiple potential sources for leaks in this area and they can get into that locker in front of the refrigerator. The hot and cold water hoses are for the galley sink. The leak here was from the windshield screws above which to fix was removed and rebedded. Another common leak area is the portlight above the galley.

    Thanks so much. This is great information. The starboard side rollers on the top track of mine are completely gone and I don't think there's much left of the port side top track roller. The bottom rollers I believe are in fairly good shape, but I haven't really checked them. I'd like a better understanding of the "prepackaged 5/8" metal brace". Where did you get that? I checked Home Depot for the 5/8" rollers and the only one they had was out-of-stock. The others were mostly 3/4" or 7/8". If the roller is 5/8" and the bracket is 5/8", does that mean that the surface of the bracket touches the track as well?
    Also the door lock is pretty much shot, too. I wonder whether someone well-intentioned or otherwise decided there was a need to force entry and ended up destroying the top track rollers and very nearly the lock mechanism. It's marked "KCS" and I think I read elsewhere here that those locks and the parts for them have been discontinued for some time. Do you know of a "plug-and-play" replacement?

    Thanks again for all the help. I've been eyeing the 400 EC for a few years now and finally found one in decent shape (except the door) that they accepted my offer for. I know I'm really going to enjoy having her.

    Thanks for all of the great tips and advice on my QS 7.5 generator. I think I am going to pull it so it will be easier to work on and try to see if I can identify the problem. I'll let you know how I make out.

    Here in Mass. the leaves are starting to fall and it was 41 degrees this morning so I'll be spending the next two weekends winterizing and shrink wrapping.

    Thanks again

    I got the brace from Ace Hardware (any hardware store should have them). Think of it as being half of a door hinge that is used to hold or support two pieces of wood/metal together. I used something like this:

    Hardware / Angles, Braces and Brackets / Metal Plates

    I drilled a hole in the middle to accommodate the machine screw into the door. For the lower track I did use the 3/4" rollers I purchased while leaving the 5/8" rollers on the top track. The 3/4" rollers were these from Amazon:

    Prime-Line Products M 6151 Tub Enclosure Rollers, 3/4-Inch, 4-Pack

    The track is actually about 3/4", so the metal brace/bracket is close to the track on the bottom, but when the assembly is tight, it does not hit the track.
    Also, the OEM setup is better described as a slide not a roller (at least on mine). It is a piece of plastic that slides in the track and is screwed to the door frame. Hence, the use of grease to try to make it slide easier.

    Sorry, but I do not know of any replacement for the lock assembly. I discovered the loop on the door frame of mine is broken and I will need to figure out a fix, at some point, too.

    Great lead. Thanks. My cabin door is one messed up piece of work. If I can get the rollers just to get (and stay) in the track and get a secure lock on there, I'll be set.

    Thanks for the link. I've been looking for a replacement lock for three years.
    I've use a cable lock to secure the door, it will be nice to have a standard lock.
