Miele W828

[dave-m]

Hey all,

Does anyone know why one of these machines would take in only a small amount of water.
I’ve cleared out the pressure chamber which was clogged up and now its taking in water, but only not enough to reach the inner drum.

Cheers

Re: Miele W828

Faulty inlet valve,mor faulty pressure switch i reckon?

Re: Miele W828

The inlet valves test ok and the pressure line looks like it goes straight to the board, is there a removable press. sw on the board, is it replaceable?

Re: Miele W828

Pretty sure the pressure switch on these is oart of thr front circuit board.
You may have a blockage in the pressure switch hose though.

Re: Miele W828

The hose is clear, i double checked to be sure.
The press sw seems to be part of the board in front of the main board (it goes through a hole on the main board and then attaches) Is this repairable/replaceable?

Re: Miele W828

I have a miele w829 i use, and they dont take in a lot of water, but you can program them to take in more for either wash, or rinse.. Or both… Info in user manual here

See page 29 onwards

Hope this sorts it out

Re: Miele W828

Ok, Help,
It’s worse it’s getting….
I went back as suggested and changed the water level setting to max to see if it would help, but no change.
When I put it on it fills for about 10 seconds and then stops and moves to the wash rotation stage. And seems to carry on as normal but with almost no water in it.

Then I screwed up and added to the problem..
I was checking the voltage to the solenoids and must have shorted the terminals as I blew a fuse (and the tip off my meter probe) and now anytime I push the on/off button to on, it fills….constantly, no matter what programme is selected and when it gets to about only 1/1.5 inches in the tub the pump kicks in (for flood protection i assume) and a fill empty cycle starts and continues.
So, I’m assuming I’ve shorted a relay on the board somewhere and even If I can solve that, I still have to repair the original problem.
The press sw. Is part of the board and I’m wondering if anything else could cause the problem as the hose and chamber are clean of any debris.
If anyone can tell me what relay (I’m hoping only a relay!) I may have goosed or if there’s is something else I should check it would be much appreciated.

Cheers

Dave.

Re: Miele W828

Ok, if you have shorts the inlet valve, you have probably damaged something on the board..you should have a circuit diagram tucked away in the machine somewhere, which should tell you what you may possibly have blown on the board…

As to the initial fault i can only guess at a leaky pressure hose, or faulty pressure switch..which as you know is located on the front board of the user panel..

I have a A3 size enlargement here of my own miele w829 which only differs by spin speed i think, so will check this out for you.. Is it the type with 3 inlet valves? If so would probably need to know which one you shorted out..

Re: Miele W828

Also if you disconnect the pressure hose from th board end, see how much water it takes in then..that will prove the switch either way..

Re: Miele W828

How did you get on with this one?

Re: Miele W828

Hi Martin, thanks for the info and sorry I’ve not replied.

The customer was away for Easter and are only back tomorrow or the next day so I’ll get to have another go then.
I’m going to stick in a spare machine and take their one home so I can take my time on it as i want to ensure its working fully before I give it back.
With regard to the fault that I’ve created on the board, I was going to send it to a guy in Amsterdam (recommended by an ex Miele guy) who should give it a complete once over while repairing the fault I caused and tell me if there’s anything else that was wrong. He sends these back with a years warranty as long as you change the shocks on the machine too as apparently they cause the boards to fail also through vibration when worn!

However, the original snag of it not filling up could still be there, my ex Miele new mate said that in 6 years he never had that fault or changed a pressure board. But we’ll see.

The solenoids are the triple type with a single four wired plug connection.

I’m not sure how removing the pressure pipe from the switch will prove if its faulty. Connected it lets in a little water and I assume if its disconnected it will just keep filling, right? Does that prove the switch?

Either way, I hope to know more in a couple of days when I get my hands on it again.

I’ll keep you posted.

Cheers

Dave
