Vax carpet cleaner - works but needs a bit of attention (Goldington MK41)

Vax carpet cleaner with tools. Electrics working but needs a little fix to a small non-electric part. See pics 1 and 2 - the black rubber grommet that seals the clean water outlet has come loose from its housing. It should look like pic 3. The machine works ok if you put the grommet in place and make sure the clean water tank is firmly in place on top of it, but needs a proper fix. Maybe a handy person can sort it out. Failing that, it's ok for parts as the model is still in production. Instruction leaflet included. Has been used within the last week.
