I have a 2006 440 DA with Vacu-Flush system, the red do not flush light in the guest head is on and the Vacu-Flush will not operate in the guest head. The owners manual shows that the cause of the light means the holding tank should be emptied. However, I think this is an isolated issue related to just the guest head. To my knowledge, the tank is either empty or almost empty and the level indicator located in the breaker panel shows empty as well and the master head system is working fine. I would think if the holding tank was full both heads would show a do not flush warning. Has anyone had this happen?
