I had an intermittant E05 fault which seems to have been cured by changing the NTC temp sensor. It only cost around ÂŁ10 and was dead easy to change.Take the back off the machine and just two screws hold it in (two orange wires go to the sensor). I did also find that the two wires onto the sensor were a very poor connection and one actually come off its terminal, whilst changing the sensor. I changed the two 6.3mm female terminals as well. Washers been working fine now for 2 weeks.
