How to replace door seal on Bosch Logixx 8 washing machine?

Hi, yes thanks - was my 1st port of call. Unfortunately none of the video clips show exactly how to get the clip back on - there was one where the engineer was fitting without removing the front but the video conveniently cut from him starting to do it to the end, without showing how he physically managed to get the darned thing back without it slipping off one side or the other - but thanks for responding!
