Miele USA W1's Water Inlet Error After Prewash

Automatic Washer - The world's coolest Washing Machines, Dryers and Dishwashers

Help Support :

@Derrick

That's really strange now. Just did a second cold-fill with pre-wash without a problem. Changed to hot fill and the error happens.

Are we possibly looking at different software bugs that result in the same error? That would be too much of a coincidence.
 
New firmware posted?

Yesterday our machine prompted on power up that there was a software update available, with the option to install now yes/no. Found this thread when I was looking to find a changelog for this update, or really any info at all for it's reason. Unaware of the current issue in this thread, I allowed it to install hoping some other feature oversights might have been fixed. Not sure if this is generally available or is maybe getting pushed in stages - perhaps by SN or age, we acquired ours in Dec 2018 FWIW.

The entire update process took about three minutes and the machine only displays a simple graphic progress bar as it downloads and installs. (I unfortunately forgot to check the network logs in time to see how big this download actually was) Upon completion the machine restarts, but in factory reset form; i.e. needs to run an empty hot wash first, and all config options have been reset to default except for the wireless connection, so make a note of your settings first if much alteration had been done.

I hadn't previously run into this prewash bug, but to date don't think I'd used that feature so can't say for sure if ours was affected. A normal wash today with prewash enabled did not result in an error, and the machine did draw hot when the main wash cycle started. This update did not, however, fix the inability to set multiple options from the console - still must be done thru the app.

When the wash day is done I'll see if I can get into the service menu and read the new version.
 
The nameplate for this machine is:
Model WWH860, Material #10666200, Type HW21, Serial 11/14916xxxx

Firmware data from the service menu:
EPW 5004
LNG 12036
ELFU 4198
EZL 3966
EZU 3864
VarGT 100206982
VarBL 100197930
VarANW 100198007
VarSP 100245132
VT GT 100213391
EK 5243

This does appear to be different for some lines compared to similar entries posted on that houzz thread, so hopefully this is a real sign of an update. I have not been through all the features though to see if there are other changes, but nothing obvious has jumped out for this one day of use since the update.
 
Cyclograph:

Since you have an 860 will you tell me if the update still includes the Baby Clothes Cycle. I use this in place of the Normal cycle and do not want to lose it or have its functionality reduced. I am not having the problem that's Derrick has.

Thanks

AFAICT there have been no add/remove/rename of the wash programs, if there are subtle alterations to the options I've not noticed them yet.

It's worth noting that the Update function is disabled by default, so be sure to turn that on in the system options menu if you want to try receiving this. Also the machine must be wifi connected (obviously) and with the mile app & associated user registration working... at least that's what the manual says about the remote updates. Not sure if the Remote Control option also has any affect on this function, but it is enabled on ours.
As to how and when Miele is rolling this out... who knows. It seems likely they should know exactly what machines are affected by SN, so you'd think everyone in that category would receive it now or very soon. Assuming this release actually is The Fix, maybe the field techs can manually install this now too... could be worth a service call to expedite.
 
Thanks, Cyclograph

I have received at least 2 updates to my 860 since I have had it, but I think at least one was only to the WiFi module. When the update is available there will be a notification in the phone app. I just used the machine and no update, so I will be on the lookout.
 
I love how there is always one post that will forever accompany a Miele related thread without proffering any support.... It blows my mind.

Anyways. What is the fault code so I can do some digging?

I haven't sold any of the W1s but I have all of the service materials for them.
 
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.

MB and Miele Service

 

<span style="font-family: helvetica;">Well, luckily I haven't had to use Miele Service yet but I'm told by the local company I shouldn't have any issue getting service if I need it.  I bought an extended policy through them.  When I bought my BOSCH washer and dryer from them in 2002 (no one else sold them here back then) I had to use them a few times for service and I was very pleased.</span>

 

<span style="font-family: helvetica;">As far as MB service is concerned, I have no issues with them either.  They will come and get the car and drop off a loaner if needed, etc.  Other than scheduled maintenance we haven't had to use their service much either.   Very happy with this dealership.</span>

 

<span style="font-family: helvetica;">I think what it boils down to is whether or not you have a good dealership and/or a store that values servicing their customers well.  We are lucky here on both for a small city.</span>
