Thanks again Mike, picked up the mail today and there was your package. Always nice to be able to read the manual when all else fails I also picked up a bunch of o rings to replace a couple springs. One was missing and another broke as soon as I touched it.
You mention the t1/t2 switch, in the WD manual it says that controls the for the heater T1 - 25 min green LED, T2 - 8 min yellow LED. If you are missing the WD operation manual I can send a scan.
I think I see what you mean by silver deposits in the last tank. The rollers are very shiny and the is a lot of black deposit on the metal. I did find a Kodak pub on cleaning this up, it should help.
