SELF SOLVED: FOUND THE CURE FOR A NON EXISTENT FAULT!
now this might seem obvious to some BUT...
It seems h11 IS NOT A FAULT!!
It means the TIMER DELAY is SET FOR 11 HOURS DELAY!!
It is described here on the Hoover Site as H11 (upper case H)
> 'H' and a number in the display > The delay start is active
BUT the machine displays it as h11 (lower case h)
However despite repeated pressing of the delay timer button, at the top right of the LCD display, it would not change to setting to zero! (maybe the button was stuck internally?)
THE CURE WAS:
SWITCH OFF THE POWER THEN SWITCH BACK ON
WHILE PUSHING HARD ON THE TIMER DELAY BUTTON!
THAT SEEMED TO RESET THE PROBLEM
BACK TO NORMAL OPERATION!
Hope that's of some use to someone that has this baffling problem
BUT WHY it did a similar thing a few times over just before going
into spin mode remains a mystery? At least hopefully it won't do it
again, but if it does hopefully this "cure" will work again!
