DDR missing

[Tobbe]

Hi hope you can put some light for me :-)
I run Apex AOS version 5.05 BA19, and one strange thing is one of the two DDR goes missing and not come up, i didn't mind as i fill it every other week but then it come up after a few months. Then after a few weeks was gone again and after a few weeks it comes a notice in fusion "new title" i looked and there it was again
I don't have any clue why its act this way. I also had some other strange things happen like MP 40 went of and reinstall and it was ok , ATK alarms but it was water in one of the sensor replaced it yesterday and its looks like its ok now but thought it would last more then 2 years.

The DDR is notorious for going missing. This is usually due to either a failed optical sensor or liquid damage to the circuit board just below the top of the unit. Neptune repaired my DDR 3 times within one year, each time replacing the optical sensors.
