Miele Prestige Plus 6 problem

[PaulaD]

I’ve just bought the Miele PP6 washing machine and there seems to be a problem with the cotton wash programmes. Although the duration of the cycles are given as 1 hr 55 mins and 1 hour 49 mins, the timer skips forward when the machine has been going for 10 minutes or so, and the cycles run for about half an hour less than they’re supposed to. This has happened with partial loads as well as full loads. Is it normal? I’ve been told by Miele that if the engineer comes out and doesn’t find a fault I’ll be charged £99 call out fee so I don’t want to rush into a service call. All the other wash programes seem to work fine. 🙁
Can anyone give me any advice please?

To me it sounds that the machine is finishing the programme early, maybe because of your water pressure is high. If theres a lot of water pressure the machine will be filling up quickly. Other than that i have no other suggestions

Is that your ‘fuzzy logic’ kicking in adam, :rolls:

haha, nope, that was just a commom sense idea

Re: Miele Prestige Plus 6 problem

have to make a note of that one ( high water pressure = half an hour off wash times ) 😆 😆 😆

For other readers of this post, Adam is NOT an engineer and so please disregard the BS he has just offered as an answer for the problem :rolls:

Re: Miele Prestige Plus 6 problem

What may be happening:

The machine meaures the time taken for the first water fill. This inlet is usually absorbed into the dry load and the water level drops, requiring a re-fill. The electronics can deduce from the number of fills and the time taken how large a load is in the appliance. It will also consider the temperature of the incoming water and simply re-calculates the time required.

I can’t confirm this is true, because, as an independent repairer, Miele won’t tell me anything. It seems very disappointing that, as a paying customer, they won’t tell you either.

spot on mr p

as the machine has NO inclination as to your water pressure/temperature.. it can only give a rough estimate of time , working with the information at its current point in time

as water pressure and temperature have been calculated, a more accurate reading can be given, and adjusted accordingly to suit

its not a fault, its a ‘feature’

you may find the times may differ at different times of the year, as water temperature changes with the climate

have you noticed a poor wash performance? if not, then its not a fault, its technology at its best

please, ignore adam, he basically hasnt got a clue, for some reason, because hes got a job designing kitchens on a pc in his gap year, he somehow thinks that makes him an expert

hes also not 20 yet

Hi Paula,

The guys are correct, the machine will vary the time dependent on conditions and, as said, this is often referred to as “fuzzy logic”.

Depending as said, on water inlet pressure, incoming water temperature and also both the absorbency of the clothes and amount of them the machine will recalculate the time required on the fly and automatically update. Many, many machines with countdown timers will work in the same manner and it isn’t a fault so, if you call Miele, they will charge you for the privilege of their company to check it.

These countdown timers are intended as a guide and are for information only, they will almost never give the same result twice due to the amount of variables in any given wash.

I hope that helps.

You see Adam, you didn’t even notice the cryptic message in my answer. 😛

You obviously don’t read the Miele brochures as carefully as you think. 😀

Re: Miele Prestige Plus 6 problem

If the machine has advanced ‘Fuzzy Logic’ intelligence, it may even skip a rinse cycle or two, if it can detect that the rinse water is clear of detergent residue and/or foam. I had an AEG that seemed to do just that.

You may notice that a load of towels might take a longer time to complete than a load of shirts and underwear. This is because the towels will absorb more water, taking a longer time to heat it up. Also, the towels will probably require the usual three rinses, at least; possibly executing a further rinse if excess foam is detected.

And as other posters have mentioned, the cold water is warmer during the Summer (less time to heat up), than it is in Winter.

Re: Miele Prestige Plus 6 problem

Some top of the range stuff has an infrared turbidity sensor incorporated, which will measure water clarity. Don’t think this particular one has though, as manufacturers will brag about it in the sales blurp.

Re: Miele Prestige Plus 6 problem

In that case, it probably only has basic foam detection; instigating an extra rinse if required.

Re: Miele Prestige Plus 6 problem

Thank you all very much for your help – especially putting me straight on Adam’s solution as I’d have believed him otherwise! 😳
The clothes have been coming out clean so it must be ok. Thanks for putting my mind at rest – I don’t understand why Miele couldn’t have explained it to me as simply.
This is a great site and I only wish I’d found it beforehand as I might have gone for the ISE!
Thanks again.

I did think of absorbing times and water temperature, but didnt know how to word it. 😉
The sensor controls would also as Trilobite says possibly remove a rinse by a ‘turbidity’ sensor, but this is rarely found on washing machines and is more common on dishwashers. Another factor that will affect cycle times is the load balance when spinning, if the load isnt balanced the machine will try distributing it several times to rebalance it, usually if they can’t they just stop and you have to do it by hand, that was just another idea.
