We recently bought a Trioliet Solomix 2-2400 tub mixer (2011) and there is an intermittent issue with the door and conveyor working. Sometimes it works fine and then just cuts out. And other times it won't work at all. Seems more electrical than hydraulics as the rear door and side shift works fine. Just wondering if anyone else has had a similar issue and how did you overcome it as I'm a bit stuck on what to try next other than to get the dealer out. Thanks.
