Re: Hoover DYN9144DG gone bang !
Door locks often fail on these, taking the pcb with it 99{e5d1b7155a01ef1f3b9c9968eaba33524ee81600d00d4be2b4d93ac2e58cec2d} of the time.
You can usually release the door lock by removing the lid and prising the latch free, lock is usually near to the top so easy to access. No emergency release AFAIK. 🙁
There are a few different versions so the long number beginning with 3100**** is needed to verify exact model.
