at first I thought the problem (small leak during wash) was due to the small missing
pieces around opening gasket but am now thinking it's the door itself not sealing
tightly enough with the automatic locking mechanism and water gets inside the glass
enclosure bottom.

is there a DIY guide to taking apart the door and perhaps getting some spare parts for
the Bosch Nexxt 500 series or perhaps someone can recommend an online forum that you
like.
