As you all probably recall I got my new Miele W3033 in January, and absolutely love it. I've got over 300 hours on it so far :-) Anyway, about a month ago the LED drum light started to not work all the time. Not sure what to expect, I contacted Miele and explained that I'm very capable of such a simple repair, so they agreed to send me the LED drum light assembly. While it was in route, I took the top, front and sides off to do a bit of inspection to see what the problem was. Come to find out it was not the LED drum light assembly, rather the wiring harness connection had a finicky connector where they were pressed together. When the machine was on, a jiggle of the wiring harness connector was clearly the source of the intermittant short. I contacted Miele again and said that I found the problem was actually the wiring harness, and they shipped that out to me. I spent about 2 hours carefully disassembling the machine which was very easy, replaced the harness, new LED light, photographed the insides and put her back together. She's been running perfect ever since. :-) Here are some pics!

Problem with LED Light

Bad press fit connection - happens, can't get too upset. Nothing is perfect in life :) It's fixed now!

Transformer

Interestingly, a lot of the components like the water valves, water control motor, main control board all run off 220. I'm not sure what parts run off 120 though, other than the heater. I'd guess this would be called a step-up transformer :) Makes sense - that way Miele doesn't have to manufacture special 120V valves, boards etc. Just throw a transformer in.

Drain pump and wiring harness connector under cover that connects the 220 volt transformer to the rest of the unit.

Imbalance Sensor (I think). This gizmo is mounted to the drum cradle, so if the drum is out of balance too much, it causes something inside to shake and create pressure fluctuations that route up to the pressure sensor on the main board, telling her to rebalance. (From what I could understand from studying the machine and reading the service manual).

Air pressure assembly, which routes to the imbalance gizmo above, and then to the main board pressure switch.

1060 Watt Heater Assembly - 159F / 70C Max, and it actually reaches target temps, unlike LG's :) Thermistor is in the middle with the brown wires.

Motor cover, with another sexy Miele Logo. The connector just directly under the "L" in Miele is the tachogenerator cable that tells the mainboard current motor RPMs. (W3033 is default set for imbalance monitoring with a combination of the tachogenerator + imbalance switch for monitoring).

Sump float. If anything starts leaking, water will pool in the sump area and send a may-day to the mainboard. Display will say "Waterproof system activated". This better not happen until I'm about 50...

That's it

Ok I'm done :) Thought you all would like to get an inside view of a Miele. I've scoured the internet for photos of similar models but they are very hard to find. Wanted to share the inner workings!

It's simply wonderful! In my opinion nothing can compare with Miele care in building its machines. I'd love to have a look inside my W4446 too! :-) Thanks for the beautiful photos!

Beautiful machine!!I Love my Miele! This is one of the best machines on the planet in my humble opinion. I am still thrilled with it.

Sump float

Andrew,

I'm afraid you'll have to wait longer than your 50s to see any water in the leak-detect sump :)

I haven't ever had a leak in both my machines (bought in 1984 and 2000). Nothing (hoses, gaskets, other rubber parts) has ever ben replaced.

Is'nt that the pressure switch telling the controlboard the waterlevel in the drum?

That washer is so clean and new! It's a dream! And yes the MIELE logo is sooo sexy! ;)

**********

I'm not 100% sure how the 2 devices work together. I know the white air gizmo down by the heater has an air hose that connects to the little round gizmo mounted to the front cradle, and then from there it goes up to the mainboard pressure switch. I wasn't about to take the thing apart to see how it worked, digital photos only :)

Thanks for sharing this!

Hi, Andrew, thanks so much for taking the time to share all of these great photos.

Boring? No way!

Because of great advice from people like you, I'd (very recently) decided to buy a Miele washer, too — same model as you: W3033.

We love it, too!

Thanks!

Bernina,

No problem. When I bought it, I even fell asleep in front of it a few times watching and listening to it. *I'm in need of a Miele Intervention*. When my partner returned from Antartica in March, he thought it was awfully small vs our LG. It's exactly 1/2 the capacity but washes so much better. It actually uses WATER! It's hefty build, and high quality components will outlast the LG's I had previously by 15 years I hope.

I will post more pictures of it and it's matching dryer and pedestals once I get the basement finished.

Andrew

ha!

My husband definitely laughs at me for watching ours, too. But you have to, if you really want to learn what's going on with all the cycle options... and it's just fascinating. :-)

I couldn't fall asleep watching ours, though... it's on a hard slate floor. Not so comfortable.

Andrew, that's great, but...

:P

If it has a LED drum light and a wireless port, yes! LOL

Every component in your machine screams "QUALITY!".

It looks very robust.
