2200 Valve 2 failure Error 1. Open the DGA monitor cabinet
and locate valve 2. See Interior
parts (page 22).

manual lock on valve 2. If the
grey knob is pushed down, the
valve is locked and that is
causing the error.

clockwise 90 degrees to open
the lock and resolve the error.
If the lock is open the valve must be
replaced to resolve the error.
