Miele PW6055 Supervisor Code lock out.

I purchased a Miele PW6055 on the used market a few months ago, the problem with it is the previous owner has forgotten what the supervisor code ( usually 000 ) is, and it will not let me in to set the timer and other functions, unfortunately also the display light is constantly flashing whilst on sleep mode. I have been quoted well over £100 for a tech to come and rest the code with software but I cannot afford that at present. Does anyone know if there is a trick to access this code - it won't even allow me to set the clock without accessing the advance functions. Any help appreciated. The washer gives you three chances and locks you out for an hour and it could be 1000s of different codes I've tried 123 , 321 etc with no luck.
