Reply to Loftus. Who unfortunately does not state the product code so I picked one version of L76685NWD purely at random “From looking online the ducted fan assembly is a complete unit including the fan for £70” Via AEG website the fan motor is £56 as opposed to £75.91 from Partm*ster Sharks and the heater air duct housing is £63 from AEG as opposed to £81.45 from Par*master Sharks ( of `we make spending over the odds a pleasure` fame! + p&p ) – if you hit the picture dots you`ll discover no fan motor comes with it only the plastic fan, which on reflection, is the one you really mean but is probably not the culprit ( but could be if the plastic fan blade warps ) i.e. the electric fan bearings might be shot. Actually you might even have have a dodgy outlet pump – runs for perhaps 2 hours, gets hot, makes noise, nuked pump bearings = new pump! Could consider that being the cause too! All guess work unless you prove otherwise and the trouble there is disconnecting the supposed offending part i.e. the electric fan motor will just flash up a fault code (?) so you might not prove anything `cause the machine will abort the programme – modern stuff, don`t ya just love it?.
