Miele Replaced WWH 860 WCS- due to Prewash/Add Laundry Error
So I found this thread a little while back and was waiting for a resolution with my appliance vendor/Miele. I took delivery of a W1 WWH 860 WCS in February and immediately had the Prewash and Add Laundry errors. Over the last six months Miele had my appliance vendor replace both pumps and both control boards, during multiple diagnostic and repair trips. When I saw this thread pop up a couple months ago, I realized it was a problem for many. My machine was connected to the internet and never got any updates.
Finally, Miele approved a new machine a couple weeks ago, coincidentally just as they were rolling out updates to the W1 line. The equivalent of the WWH 860, the WXI 860, now occupies the second tier under the new top-of-the-line WXR 860, which appears to differ only in the new full touch display. I chose the WXI as I felt it was easier to walk up and select the cycle with a dial and press start, then to dig into menus.
So far, so good. I have not been able to create any water intake errors. So it looks like a new machine solves the issue.
Differences between the new machine and the old seem minimal:
1) Wrinkle Free has been replaced on the dial with Proofing
2) TwinDOS defaults to Whites on Normal cycle (??)
3) A new AllergyWash extra option
4) There's a new section in the manual about PowerWash. I never noticed PowerWash working with the WWH, but now on certain cycles (eg Normal) on small loads a jet comes on and sprays into the load while the drum is spinning at medium speed. Not to be confused with the jet that spray on the glass. Maybe this was active before and I never notcied it.
5) Selecting more than one option from the display is still not possbile, and the suggestion that you can select more than one option has been removed from the manual. You can still select as many as you want from the app.
6) Dress Shirts now defaults to having a SteamFinish
7) There's more cycle information in the manual now. Certain cycles add rinses if needed. Maybe this existed before, but now it's documented.
In any event, if you have the water inlet issue, I suggest you press for a replacement machine. If you have the WWH 860, you should be able to get the new top of the line with the full touch display (WXR) if that floats your boat.
