We have got the same problem... we have had ther unit for 5 years, we had Hotpoint out 3 years ago (we didnt pay the extended warranty), the engineer reccomended a defrost (funny, they are supposed to be automatic, sold under a misconception!), has worked fine until now, we have an engineer scheduled for next week, we will let you know what the answer is. What gets me is that the legend says 'intelligent care', this unit is neither, i hope Hotpoint read this, there is obviously a problem but no error code, obviously the unit is microprocessor controlled so why no warning to guide to the fault! Totally crap.
Sorry it doesnt give you an answer, I feel better though. I design control systems for a living, thats why I find this 'Inteligent care' even more annoying because it gives no guidance other than 'get the engineer out' at god knows how much for the first hour or part thereof. If at least there was an error code, one could check what it meant and how much, this would then help with 'do I go buy a Bosch!'.
