HELP! BREVILLE BES870 Problem. (VIDEO)
We have a Breville BES870. A few days ago I noticed that I no longer get any water from showerhead, instead it is coming out in the bottom tray. Steam wand kinda works, but does not produce enough pressure anymore. Also, machine makes a weird noise when it operates.First I thought a tube inside the machine was clogged, opened the machine and checked all the tubes. All were OK.I've attached some videos to further depict the problem. I'm hoping someone could advise which part/s needs replacement. http://imgur.com/gallery/9t8I41a http://imgur.com/gallery/kwfN8tV http://imgur.com/gallery/WbzxZ8n

The water coming out the bottom says solenoid valve to me. The steam not heating says some part of the heating circuit (relay, thermal fuse, element). Can't give you part numbers sorry, hopefully someone like noidle22 will chime in.
Scale blockage or malfunctoning three way solenoid is the root cause. Scale in these machines is a catastrophic problem as it causes a cascading selection of faults once the scale comes away from the thermoblock and moves down the system.
The symptom of water into the tray is the safety valve on the pump opening as the water can't flow to the group and needs to go somewhere.
Descaling probably wont work in this case as it's got no water flow at all.
You'll need to disasssemble and manually clear the solenoid, check the surrounding tubes and fittings as occasionally there can be a blockage in them.
Once clear, descale the machine. A similar fault may reoccur in a few days, just descale again. You need to keep doing it to get all the scale out.
If you get into the solenoid and there is no scale problem, the solenoid will need to be replaced as it is faulty.
Appreciate for the replies. I have taken some photos from the inside, just wanted to share them with you in case you have some further recommendations.Seems there is some damage to that part on the right...?
