Hi, I have a recurring problem with my dishwasher (Hotpoint LTB 4B019) whereby the dishwasher fails to complete a normal wash cycle and displays a flashing on/off light plus lights on for F1 & F3 - I have assumed these lights concur with your listed codes above although they are 'eco' & 'heavy wash' selector buttons.

Following a lot of internet research, I thought it may have been a faulty door interlock switch, so I have changed the switch however the symptoms prevail. I am able to eventually get the dishwasher to work by resetting the programme, however it is really irritating to have to do this - appreciate any suggestions/advice.

Thanks,

Andy K
