    Unhappy HELP! BREVILLE BES870 Problem. (VIDEO)

    Gene Cafe Coffee Roaster $850 - Free Beans Free Freight
    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...?

    Nicolas, I'm having the EXACT SAME issue after replacing a solenoid valve (which was originally plastic and broke). Metal solenoid valve replacement took 1 month to arrive (backorder via 3rd party site - Breville doesn't care about parts for their machines; want you to buy $500 machine because of $5 replacement part) and machine was sitting disassembled like that for a month.

    I'm guessing all water inside dried and this exact behavior (that's in your videos) started happening after I replaced the part today.

    Did you resolve your issue?

    I'm going to check the whole solenoid now per noidle22's suggestion...

    My machine has much the same problem, makes steam at the portafilter, hot water spits and surges with steam, steam wand has negligible steam.

    Rang Breville, was told to take off shower screen to check it was clear, then part fill filter basket and put blank disc in to check pressure, pressure meter went to one o'clock which meant pump was still working.

    Took back to HN to action extended warranty, has been sent to Sydney for repair. A long list of parts to be replaced. Was offered a new machine (but no extended warranty), or store credit, or repair with extended warranty remains to 2022, took the latter and now waiting for return of repaired machine.

    Had been working, clean me light came on, ran the program, everything O.K., did a vinegar and water flush, problems started as above.

    I believe the vinegar loosened scale and created a partial blockage. Only 2 years old, used daily, say 3000 shots (2 years x 5 daily x 6 days x 50 weeks). In tank filter every two months and Gladstone tap water.
