Indesit washer dryer light flashes 13 times

“I have an Indesit WD12 washer dryer. The programmer keeps turning/clicking around and i note that the on/off red light flashes on a cycle of 13 times on and off as the dial gets to a certain point. I have tried to reset it as in your suggestions ie turning the power off turning it to one of the ‘off’ black dots (there are 3 of these0 then turning it back on again but to no avail. Any ideas please?”I have an Indesit WD12 washer dryer.
