Beware of this model of machine. I bought mine 3 years ago, within 4 months red lights flashed and stopped working (luckily it was still within its warranty so I didn't hesitate to call out engineer). He said it was a faulty sensor. This month, machine stopped working again due to same problem. Phoned Zanussi to be told it would cost £130 to fix this one time only or £170 to take out a year's insurance (which includes replace with new if unable to repair). I always clean filter, empty filter and clean out condenser yet the machine still displays a fault. Do your research on this common problem before purchasing!
