Hotpoint Washer dryer BHWD149 door wont open and there’s no emergency door release tab from what I can see. I tried putting it on a drain programme but all the lights just flash on the machine? Emptied the pump still nothing and turned it off at the wall and still won’t open. I did try start an actual wash programme as well but again the lights on the display just flash and no programme starts. Any ideas? Thanks in advance
