I had a similar issue with three lights remaining on
E6 in the manual - the dishwasher is unable to discharge the water from the tank...
I tried the pressing the select button 4 times straight after switching on the appliance (below the lamps come on), then switch it off and then press select button one more time on power up and bingo.... it was reset
Thank you Mr P as that save me money and MFI are no longer in business
