I write to tell you we had exactly the same problem with a new beko machine intermittently leaking, it could be ok for 2 weeks or so and then leak again, not a massive leak from the right side but no washing machine should leak at all despite what customer services say. We had the beko engineers out 3 times, 1st time he said there was too much soap suds and we should use more comfort to kill the foam, did this with no improvement, 2nd and 3rd visits they could find no fault with the machine, 3rd guy admitted he had been to a few with the same problem, this shouts manufacturing fault. Retailer just refered us back to the engineers.
The problem remained so as a retired engineer I had a go myself and couldnt find a problem, it was driving us both crazy as I cant live with any machine that is faulty, we had a little lottery windfall and scrapped it, 10 months old and leaking from day one, then bought a Bosch machine which is brilliant so far.
I know its extreme but that machine was obviously a lemon and we couldnt live with it.
