Baumatic BDW 45.1 Leaking From Door

I’ve got a BDW 45.1 slimline dishwasher, which I inherited on moving into a new flat last week. The first time I used it, I put it on a rinse just to clean it out, and after about 5 minutes, water started leaking out the bottom. I thought it might just be a bit clogged up so cleaned out the filter and cleaned up all the seals around the door, but this made no difference. It’s only a couple of years old I’d guess, and the seals at the sides and bottom of the door don’t look damaged at all. The water doesn’t leak out immediately, but a few minutes into any programme water slowly begins to drip out, mainly from the bottom corners of the door I think – as it’s integrated it’s a bit difficult to see exactly where it’s coming from.

Any ideas what the problem might be? From what I’ve read elsewhere on here the BDW range aren’t exactly brilliant build quality, but has anyone got any suggestions?
