Subject: [TN] MOV issue

Hi,
 
I need help on issue regarding the MOV. We are using this MOV on one of our
PWA. This PWA goes through the cleaning process (aquawash).  Then the PWA is
subjected to various tests.The MOV failure happens during a high voltage
test due to hydration of device during cleaning process. 
 
I am attaching the datasheet above. the Part number being used is
CU3225K275G2K1.
 
Has anyone observed this before? Can anyone let me know what can be done to
prevent this failure. (At the moment, we cannot stop the cleaning process
during the PWA build).
 
Looking forward to comments and help.
 
Rgds
Prashant
