Hello, Bob again. Well switching my 'Bosch Logixx SGS09A02GB' dishwasher off at the wall only worked 4 times in a row, then the 1 minute left problem returned. The worst thing about this problem is that if you're not there to switch it off manually it just keeps rinsing for hours using loads of rinse-aid, water and power, then never switches over to drying to end the cycle.
I seem to have finally 'fixed' this by swtching off drying on the options menu. At least the stupid thing finishes automatically now and if you leave the dishes in there with the door closed for a while it does a decent job of drying them anyway just by using the residual heat left from the wash cycle.
The cause does seem to be a faulty, burnt out circuit board. If you are a bit 'handy' you can replace this yourself. Apparently the burnt part is pretty obvious. But if you don't want to do this (only for the fault to return?) then the above workaround seems to work pretty well. At least I don't need a new dishwasher now!
