National 675 Coffee getrting heavy condensation inside cabinet

[cvending]

Went to my location and found the inside of my machine covered with moisture. I assumed it had overheated. Waste bucket was not full.  Temp sensor displays correct temp. Temp set at 185 degrees (FD machine).  Cleaned machine. 2 days later same thing. Crane has techno idea but will pass myt situation  on to lead tech for a possibl;e answer. 3 hrs--- no answer-- shocking.  ASny ideas?

It sounds like it's overheating.  It might only last for a short time and has cooled to normal by the time you get there.  Do make sure your exhaust fan is running and it's filter is clean.  You could also have a bad tank lid gasket.  Maybe replace the triac to rule that out.  While it's solid state and when it fails it stays failed maybe it's iffy?  That or a bad relay board.  I'd also replace the thermostat to be safe.

Thanks for the insight AZ. I have changed the Triac, exhaust fan is working, cabinet fan is working, no leaks. I did lower temp setting yesterday. Decimal point disappears when water gets to set point. Temp sensor seems to be working properly but will try that next

A leaky tank lid gasket seems the most reasonable spot for steam to be leaking out and collecting on the walls, cooling and condensing.

I will be visiting the account again tomorrow. I kind of doubt the gasket as it would then be a constantbuild up of moisture. But I am up for anything. Ifg I learned nothing else over the years... 

Don't rule out anything!!

That's the fun part about repair.  You never really know what you're getting into that day but you can bet it'll be sticky.
