dishwasher help

i have a bosch classixx dishwasher, looked for code round the door and havent found one as yet. all of a sudden its started leaking from the under tray but theres no leak round the pipes as we can see so far, the water does seem clean and its not constent. we moved it cos we are having drainage props with the sink next to it and as we moved the water came pouring out this tray. can u help me work out if i should be worried or if this is just a prob with moving whilest not fully drained…thank you
