I have a new Miele T4362 vented tumble drier… I’ve only had it for 5 months so it’s still under warranty but before I go to the trouble of calling out an engineer (and taking a day off work waiting for him/her!) I thought I’d ask in here if anyone has any thoughts as to what’s going wrong.
When I first got the machine it wouldn’t run for very long before the “Clean Out Airways” light would come on. Reading the manual I discovered that the vent I have is a bit longer than is recommended. However the previous tumble drier I had worked fine with this and the Miele manual said it was okay – it just wouldn’t be as efficient…
I also discovered that there was a way to program the machine to ignore the “Clean Out Airways” warning. So, sure that it wasn’t actually blocked, I turned the warning off.
The machine has worked perfectly until this week.
It now won’t run for longer that 5 mins before the “Clean Out Airways” warning comes on. I’ve checked that the override is still set – it is. I’ve checked that the airways, both in the machine (as far as I can) and outwith the machine are not blocked – they all seem fine.
Is this just a fault that I need an engineer for?? Any suggestions?
TIA

Re: Miele tumble drier won’t run for >5 mins
well i got an engineer out to look at it – his repsonse was the machine is working as it should do and charged me £70 to tell me that! 😥
I cannot convince Miele or the engineer that it’s not and I’m left with a very expensive drier that won’t (dry that is).
The air extract is not blocked.
The length and width of the air extract is within the tolerances specified by Miele. It is towards the maxium length (but still within) and I apreciate that it may consume more electricty this way but it should still work.
The machine has been ‘programmed’ to have the “clean out airways” warning disabled.
Yet after less than 5 mins of drying it switches off with the “clean out airways” alarm going off.
Any ideas on how to progress/fix this gratefully received. 😥

Are you sure that the vent hose has no sharp bends/kinks in it? This can sometimes cause a poor airflow. Try the machine in a different position, with the vent hose as straight as possible.
Check also that the duct (if it goes through the kitchen wall) is clear of fluff (it can build up!), and that the outlet on the exterior of the house is also clear. Make sure any hinged flaps are able to move freely, and are not blocked by bushes, garden furniture or rubbish bins.
If all the above checks out, get back onto Miele and politely, but firmly insist that the machine is not performing as it should; that you have complained about it before, and that the fault has not been rectified.

interesting this one
very unlucky that, being nailed for £70
its hard now for engineers in general, because there are people out there who call engineers for the slightest thing, and its increasingly difficult to be fair with people, especially since 85{e5d1b7155a01ef1f3b9c9968eaba33524ee81600d00d4be2b4d93ac2e58cec2d} of the time, the solution is in the handbook
suggestion? since u admitted the vent hose is longer than miele recommend, are you sure the vent isnt being obstructed when its pushed into its normal place? its often the case that by pulling the machine out of its usual hole, you also remove any kinks/traps in the hose, which would explain why it showed no fault for the engineer
if you need to be 100{e5d1b7155a01ef1f3b9c9968eaba33524ee81600d00d4be2b4d93ac2e58cec2d} sure its the dryer itself, pull out the machine and put the vent hose out of the window, so u can visibly see the hose has no kinks, and make sure that while the dryer is running, that the hose is emitting warm, moist air. simply by putting your hand over the end of the hose
if the problem re-occurs when u do this.. then u have a problem, and as trilobite recommends, get onto miele and politeley insist that it just isnt right. ( shouting at csa’s on the phone, doesnt lead to better service, trust me)
im surprised a miele appliance is giving trouble, these machines just dont break down like others do, and faults that do occur are generally simple
hope you get sorted

on the contrary i said it was within Miele’s tolerances. At the moment I have the kitchen unit that was beside the drier removed and I can see the back of the drier and that there’s no kink in the tube leaving the machine.
I’ve also not used the normal tube (thin plastic material with the coiled wire in it – not sure what it’s called). I’m using a rigid tube normally used for drainage. That comes out of the machine and after 6″ does a 90′ turn downwards through the floor for 12″ or so then another 90′ turn followed by a 12′ length that goes out through an air brick in the outside wall. All of this through a smooth walled pipe. 🙂
All of this when added up is still within the tolerances stated in the Miele installation instructions.
However this is missing the real issue / point.
The machine stops working when the “Clean Out Airways” alarm comes on.
The Miele can be programmed to over ride that alarm – which i have done. Despite that the drier still stops and displays that alarm.
Thanks anyway for all the helpful suggestions though. I’ll be back on to Miele in the morning (or is it Domestic s & General I never know who you’re actually dealing with nowadays!) and this time the engineer will have to deal with me when he comes and not my wife – which means a day off work unfortunately. 😥

Re: Miele tumble drier won’t run for >5 mins
so however you do it, it will cost you
i wasnt havin a go m8, you can have an 80ft vent hose, as long as its not kinked, it was only a suggestion… good luck with miele anyway

Im sure you can’t 😕 as you will get to a point where the vent air will finally drop off and thus cause condensation to form inside the hose and result in poor drying and may even start popping safety thermostats to boot 🙂

Miele will allow up to 100m if a 150mm pipe is used in a straight line. If the pipe is thinner then the max allowable distance decreases e.g. only 20m with a 100mm pipe.
If there are bends or if it’s the flexible pipe normally used then that further reduces the maxium lenghth allowed. e.g. one 90′ bend reduces the length by a further 1m.

Hi Malcolm
I stand corrected 100m (app 300ft) what a length 😯
Going back to fault, the diagrams don’t show any of the venting going downwards, whether that will have any effect on the appliance ie heat rising etc 😕Greg
