The problem is the solinoids that activate the water coming into the trays. One is not woorking, and needs to be replaced.
Please provide the full model number from the manufacturers lable on the unit. It should be just behind the door on the chassis.
Checking for 857051415597 I am sorry but it is not showing as a good number in my database.
At this point I will opt out and this will open the question up to other experts to answer. Sorry for the inconvinence.
Sorry to jump in here.
It is a UK model.
Your question has now appeared on my screen in the UK appliance category.
I know you've checked some of this.
Take the dispenser drawer out and look into the dispenser and up to the roof of it.
Is it clogged?
If it is, scrub it out and use garden tying wire to poke the holes clear.
Try it again.
If it still doesn't work then it's likely the dispenser top will have to be removed to thoroughly clean it out or, the inlet valve supplying the conditioner compartment has failed.
Check this out and see what you find.
Hope this helps
Let me know how it goes or if you need more help.
Unplug the appliance and pull it out from under the worktop.
Take the top off.
Take the dispenser drawer out.
Take out any screws revealed.
Take the hoses off the dispenser (make a note of where they fit and label them).
Take the complete dispenser out of the appliance.
You can try cleaning it in the bath, use a shower hose and see if you can back flush the holes. (Sorry, you're going to get wet).
Once cleaned out, refit the dispenser and try the machine again.
At the rear, do you have 2 hoses supplying 2 valves or does the cold hose have two valves?
Good luck with it.
There's nothing wrong with your valve.
It will only ever take in hot water on the hottest wash and even then it's very little.
The rest of the time the machine only takes cold water and heats it as required.
If the valve was faulty then the appliance wouldn't work on the hot wash and it the electrical coil on the valve was faulty, the machine wouldn't work at all.
If you've cleared the jets and got the conditioner working, you're sorted.
Well done on the achievement.
You're very welcome.
Thank you for the payment, it is appreciated.
