I've bought five from a Experience trade show special. Two of those have been in a completely clean medical commercial building that we clean (to lower humidity) and as of last night of of them (626 hours) came up with a error code showing that the high voltage board is not functioning. This dehu is less than a month old. Out of all of the dehus I ever run none have failed unless it is in the thousands of hours, not hundreds. Anyone else having trouble with the Revolution?
