Hoover VHD flashing display

[Pwcomp]

hi there, firstly i have gone through all the searched pages i can find on here i can think of, and looked at help pages with out luck so hopefully Ive not missed the answer, I have a hoover VHD sensor Dry washer dryer 6+5kg model, have got an odd problem on it, in that when switching to high heat dry, first i cant change the time now?, and secondly after it runs for about 10 minutes, it stops and the display and buttons flash...

 

If anyone has seen this sort of problem before perhaps you might enlighten me..

have a good day :-)
