I can't help with all of your questions but will try a few as I have an 04 Adventurer.
1 The water pump filter- First make sure there is no water in the tank and city water is not connected. Then it is easy to get to and the top turns about 90 degrees which will open the top and you will then be able to get to the filter to clean it. Make sure when you put it back together that it is tight or leak city.
2 As far as the fridge I would be leary of shorting anything as your wiring maybe different than everyone else. two things I might try would be 1) disconnect house battery Positive terminal and then reconnect or 2) unplug fridge from AC and while pluged in replug it in. The next thing I would do is get in touch with Norcold at
www.norcold.com or get in touch with Winnebago customer service at 1-800-537-1885
3- AS for grey holding tank, I would try what someone else said put some water into it through the shower or kitchen sink and see if it comes out. I can't see a plug stopping the water. When I open mine it comes out fast and then trickles too so there may be nothing wrong.
Good luck and I hope this helps.
Tom

Thank, Tom. Do you or anyone know if the code is stored in non-volatile memory on the board? If is isn't then what you suggest would basically clear the code, but if it is then simply disconnecting won't help. I am reading the manual from Norcold for my unit now. It suggests that you need to short the #15 pin to ground to clear the error code. My research on here also indicates that this "no co" condition is fairly common. I think that I may try and install a "reset" button for the future. Of course, there are some wires that you have to disconnect
before hitting the button, but it would save having to pull the cover off the box. My unit is out of warranty, so I should be OK there.
