Hi All,

Wondering if anyone else has found the following problem and what they found the cause was?

BBraun Dialog+ Evolution.
Intermittent VD (SUP) alarm during disinfect. Further investigation shows hot water being fed back into the citric acid.

Checked disinfection valve  (both types) in LLC test mode all OK function as required.
Visually checked the operation of the disinfection valve all seems ok.
Fault intermittent but happening on several different machines.
