April 2020 (25th to be precise) my washer will turn 20. This machine will get for his / her birthday a new laundryroom as we are by then (fingres crossed) at the final stage of our renovation project. This project includes a solar hot water heater.
As hot water will be readely available in the futur, I would like to upgrade my washer with a hot watervalve. The hardware is kinda available as Miele provided a punch-out hole to put a single valve and an extra "inlet spray" on the soap drawer.
Software... i'm a bit in doubt, but anything is a possibility... from tweaking the controlboard of the washer itself, to building in an arduino-type stuff.
So I turn myself to the power of this community...
Anyone who can give me some info like a plan of parts, a wiring diagram, a better idea,... please post :) This Miele Gold is actually a W963 in disguise and so part of the W800-w900 serie. People who own a US equivalent of this series, like W1918-W1926-W1930-W1966-1986, or who can provide "under the hood" pictures... I'm curious to see the waterinlet set-up.
Few notes:
I would like to opt for a system that works with the washer, meaning that I don't have to run back to change the machines inlet hoses ex. to switch for rinsing.
Last "boilwash" I did, the washer didn't wanted to spin at the end of the mainwash and after a very long "pumping the main wash water sequence", the machine showed a "drain" light. Pump clean, no obstructed pressure switch pipe, no drainpipe problem and no more problem the moment the machine cooled down a bit... any thought on this are also welcome.
Let's go...

Have a look for the service paper that will either be tucked in the control panel or tucked behind the computer if this style still has the swing open front. On my W423 which is cold fill only, it still shows the hot fill solenoid and where it wires up to. Once it’s wired in, then you just need to find the service manual to program it.
Can you find the card and then we can go from there
Cheers

The washer was regulary moved and opened for maintenance and my curiousity so I'm not sure that the diagram is still... If so "jihaa", if not google does come up with some similar diagrams... but if one could post picture I would be very happy!
Still the "hot water programming" would be challenging... any idea's to do that?
@Brisnate81 Thx for pointing out the wiring diagram

Thx... but W1986 - W1966 owners pictures request...
So the washer moved in its final position. Time to attack the "rebuild".
I looked at several wiring diagrams and found out that Miele used Y12 as code for the extra inlet valve in their schemes.
What I'm a bit confused about now is that when I look at the back of my control panel, I don't see if there is a "contact" left where i could connect (solder / hardwire) the wires to the extra valve to control i.
In fact is there somebody who happens to own a Miele w1986 - 1966 - 1926 who could pop off the worktop of it's machine and take a picture of the controlboard / motherboard? Maybe look at the partnr? Mine is an EL 200. I would really appreciate it. Note the valves are clipped at the right under corner.
