Yes, I too have a DVC in a mission critical application that gets more attention than all the rest of my stoves put together.
This stove reminds me of the space shuttle, when it's all together it is awesome but there are just too many failure points. IF, as our NC friend hoped, you are now good for another 4 years then fine. However, I very much doubt it. Now I have the pot. on the stove temp switch working intermittently. So I need spare circuit boards, pressure switches, two exhaust probes, a little spare filter (don't forget that one), 50K and 100K pots and a soldering set up and spare motors. Let's keep the fines draw clear as sometimes that fills up quickly for some reason. etc.etc.. My experience over 5 years is that it is very susceptible to power surges and protectors do not help. The circuit board blows quickly. The temperature probes need changing regularly as they get very fragile, every year is best. Be very careful when cleaning.
All these likely to go down (of course) at no notice when it's too damned cold to even think straight. All of this coupled with really c rappy local dealer non service, who even when they can be bothered to wander onto the farm (I waited 6 weeks once) and they never have a clue what is wrong. They just keep changing out everything until it works - I can do that. If I want a lesson in how to do that I can go visit my local Ford truck dealer. However, it's a looker you have to give it that. However, I already had a trophy wife and that was not worth it either.
It just should not be that hard and does not need to be. Sorry, a total POS but I paid a lot of money and I am stuck with it.
Am I beating around the bush too much? Sometimes I just need to be more direct.
