Whichever wash program is selected it eventually returns a lit ecowash light, makes a noise like it is doing something which carries on until I turn the machine off, and the on/off button flashes rapidly. It doesn't release the tablet but does fill and empty the machine. I presume that ecowash light being lit indicates a particular problem - it is the 4th program button. I don't recognise the lights combinations mentioned in the manual troubleshooting section as being this particular one.
