Does anyone know what the function of the pressure chamber is and why would there be water dribbling out of one of the spigots and activating the float switch.?The water leaks for a few seconds during fill cycle just enough to trigger the float. I suspect it is to do with the pressure of the feed as a couple of years ago I did solve the problem by backing off on the water feed. Can’t do that now as it results in no water at all. I have blown out the narrow tubes and the pressure switch which I can hear clicking. Is the pressure chamber (also known as air chamber in some places) dogy or is it another component linked to it.? It seems that the chamber is acting as a pressure relief valve but I am only guessing on this.
Any info much appreciated.

I take it that the side chamber has various black deposits in it? If so it will have a blockage and will need to be replaced.
P/no 8996464032-23/5, around £40 plus VAT etc from memory. An email to spares@ukwhitegoods.co.uk for confirmed prices and ordering.
Power off, if fitting this yourself.

Gosh that was a quick reply many thanks for the info. Yes it does have dark deposits in it. I did think of taking it off and trying to clean it but as it looked like there was a fair ammount of dismantling required to remove it I thought it might as well be replaced but did not want to do so unless it was confirmed that this was the problem and should be replaced. If any one still knows how the system works and the purpose of the part I would still like to know. I am the sort of person that likes to gain an understanding of how things work when a problem presents itself.
Thanks again.Re: Pressure chamber AEG favorit 875i
There is a main “flow path” through the chamber to allow the machine to fill. These are the wide channels through the matrix. A certain amount of water is diverted through the minor channels to pressurise the water level control system. If these minor channels become clogged, water is further diverted into an overflow system, which will vent into the undertray and trip the float switch. In a way, the system is working exactly as it should!
10 years ago, this was a regular problem – I had assumed there weren’t many of these left!
If you wish to keep this machine going, get the parts now – they aren’t going to be available for too much longer – the circulation pump is already obsolete.
Good luck,

Grateful thanks for the information it is very much appreciated. The machine is around 17 to 18yrs old but has given very little problem an element and a circuit board in the past. Although a new machine can be bought relatively cheapely these days I firmly believe that we should not dispatch things to the scrap heap if we can keep things going. Whilst there are arguments about newer goods being more energy efficient it is often forgotten that considerable energy goes into manufacture hence my desire to do my environmental bit if I can. Thanks for the tip about parts running out perhaps this will be the last repair on the machine.
Thanks again

My sentiments exactly, and your machine will probably have better quality steel (thicker!) than most of todays machines. I would imagine that your machine is a true AEG; from what I have seen in the shops, current AEG’s look positively Zanussi-ish 🙁
It is a pity that spare parts become obsolete so quickly. If the manufacturers would settle upon a robust design, and continue to implement the occasional minor improvement. Instead, they launch new ranges every few years, making the same mistakes both they, and their competitors have made in the past. Metal parts become plastic, and a 15-year lifespan is never seen again.

Hi
If manufactureres kept parts for every model they had made in the last twenty years they would need very big warehouses . And parts kept ,cost money to store . And no one can afford that.

Thats because they are part of the same group ie:- Electrolux

Re: Pressure chamber AEG favorit 875i
I wasn’t saying that.
Hoover washing machines sold in 1990, used the same basic design as the machines sold in 1980, or even before. It’s perfectly true that the control panels changed, water consumption was reduced, etc., but the machines used the same style of parts.
Then the production process was changed, and we had in quick succession:
“New Wave / Classica / Softwave” ranges
“Quattro / Performa / Excel” ranges
“Nextra / Megaload” ranges, and the strange “Vision” – a throwback to the styling of the original Keymatic.
And I presume the number of spare parts required to be held in stock, more than doubled…
Re: Pressure chamber AEG favorit 875i
Your point is valid re storage of all the parts etc, the issue is, is it necessary to keep reengineering parts.? Surely it is better to try and use as many of the original components as possible in new models it would save on development costs. The problem is that society has become a throw away society and will not persevere with mending things, it is so much easier and very often cheaper to replace. Manufacturers have paid their part in improving their production processes and costs through competition and should be congratulated as they have brought products to people who could not otherwise afford them. However we cannot keep building scrap mountains.
As for the perceived quality of new machines I have looked at Neff and even Miele but they do not seem to be of the same substance as the AEG, true they are more efficient and have more bells and whistles but will they last for as long as the AEG?

Neff products are from the BSH (Bosch) group and are largely upper middle in quality. Miele freely admit that they expect their appliances to last 20 years. This reflects in the price……..

Re: Pressure chamber AEG favorit 875i
Thanks everyone for inputs now got the part but am struggling to get the pressure chamber off the bottom outlet. Is it a push fit? How much dismantling needs to take place?. If I can get the chamber off the outlet then it should be a fairly quick job.
ThanksRe: Pressure chamber AEG favorit 875i
The original was a one-piece sump/tube/chamber moulding. Replacing it involves sawing the connecting pipe in half. Check the contents of the kit – you should have a length of rubber hose and some clamp bands to remake the joint.

Re: Pressure chamber AEG favorit 875i
Many thanks for that. I did eventually work it out when I thought about what the length of hose and clips were doing there. It was then obvious that the part also fitted other machines as the main spigot on the end of the part was too long to allow the chamber to fit properly and had to be shortened. Shame that there was no indication with the part about fitting it. It only needed a sentence to explain its universality, but then I suppose those fitting these things day in day out don’t ned the info. I have examined the chamber I took out and I am intrigued by it’s function it seems rather ingenious and wonder about how it came to be developed. I might get round to taking it apart to try and understand exactly how it works. Anyway machine functioned ok at first test wife pleased and a couple of hundred quid at least saved and a little less landfill than might have otherwise been.
Thanks again for all your inputs.
Regards 😀
