Miele Electro Repair

[richmnz]

Hi,

I have managed to buy quite cheaply a faulty Miele Electro C3.

It vacuumed up water and the motor blew up.
I have replaced the motor with another but now have an issue with the control board.

As I see, there are 4 SMD resistors that need replacing.

I am capable of doing this but need to know their values.

Does anyone know what the values are?

The board has an EDW8901 sticker.


Regards

Richard

Hi Richard, is this vacuum still under warranty?

Hi, Richard. I tried to look around for a way to find the values and thought this might work.

Hopefully this helps.

Under Warranty

Alex, he bought the vacuum cheaply, ie. USED = NO WARRANTY! That's the risk you take buying used. And in this case, the cost of the motor and circuit board will have eaten up any money Richard saved by buying used.

Also, this is one issue I have with Miele canisters made 2004 with the Vortex motor - you cannot bypass the circuit board! Any other brand that uses a ordinary 2 wire motor, like Sebo, their direct competitor, it's possible to do that. That's why I personally will not recommend any Miele made after the S500 series before 2004. The quality of the double stage motors are so much better, and don't have this issue.

Bypass the motor

I've always been too scared to run a Miele motor at full power for long periods.

I will scan the internet.

Perhaps on Ebay where some "kind" person selling an EDW8901 or EDW8902 etc will post a photo with the SMD resistors showing their values.

I don't know about motors but in the diagram posted, what happens if you connect 1 and 4 to mains?

Most of the folks around here are scared of those new-fangled circuit boards... >_>

tbh, I myself won't mess with smd stuff, though to be fair, I'm simply not equipped to handle it.

Yeah my advice would be to seek out a good board, or pictures thereof.

Best of luck.

Try taking it to an electronics repair shop like for computers. None of those diodes and resistors are proprietary, and should be able to be replaced pretty easily.

You could throw a hail mary and email Miele and ask them but I highly doubt they will tell you anything.

Rob, it's not impossible to have warranty work done on a secondhand Miele. At least here in the states, I've seen it happen at least once or twice but not all the time. Also, I would not bother bypassing a circuit board. That for sure would void the warranty. And here's what I really like about the Vortex motors, they may not be as durable and reliable as a two stage motor but they are lighter and more powerful. I have a Miele Red Star S312i and it's definitely not as powerful as the Miele Classic C1 Home Care PowerLine that I've sold before when I was working at a vacuum store. As much as I love my Red Star, I definitely would buy and/or recommend a new Miele today. They're still built and designed to last up to 20 years if properly taken care of.

Richard, if I were you, I'd get another board for your Miele. I humbly think they're not worth messing around with. I tried it once on another vacuum that I was repairing, didn't work.

When you live in NZ

Warranty work does not include sucking up water.

That would be a claim on household insurance.

If I could only read the printed symbols then I could determine the resistance.
I will now trawl Polish and Russian repair websites to see if anyone has photos
of the underside.

If the worst comes to the worst, then I will buy a used PCB from ebay.

When you don't know how to choose components and SMD resistors, I hope this will help you.

I think you can take it to an offline store for testing, and then install the corresponding resistor according to the test value.
