    Actually that's a good point - is it under the tray after back flushing or is it under the whole machine on the bench after any kind of use?

    I haven't opened one up in a long time, but I thought it was just the tube return to the drip tray when backflushing ... sometimes when hitting max pressure with blind basket it splashes over the top. ( This happened to me too but on a BEs900- thanks for reminding me to check when i replace orings all round shortly.)

    Please follow LeroyC ' s advice as I am not certain at all my 'thought' was based on fact or fiction

    There are a number of possible causes. The most likely is a leak from the top of the steam boiler. That's also the easiest to check and confirm or rule out. Other possible causes are a leaky pump, a leaky OPV, a cracked boiler etc. Start by taking the top off and turning the machine on with it off. If it's a leaky o-ring on the top of the steam boiler you'll see it spitting water as the machine heats up.

    Hi there,
    I had a similar problem and my o-ring had failed on the steamer and subsequently leaked on to the PCB and buggered the machine. I suggest you get it checked out. Hopefully it's not that.

    Thanks

    So it only happened once and you couldn't do it again? I'm guessing the drip tray want in all the way at some point. The left side at the back is where all discharge to the drip tray goes. Or the water tank wasn't in all the way when someone filled it up from the top. Or the O ring in the water tank valve is leaking?

  • Breville Dual Boiler BES920 pooling water under drip tray

    Hi all,

    I have a Breville Dual Boiler for around 3 years now. (out of warranty)

    I use the "auto on" feature of the machine to have it turn on at 7am everyday.

    Recently I wake up to find water pooling under the drip tray occasionally (Left Side) and under the machine (Left side).

    The pooling water also made the undercarriage wheel of the machine rot (No big deal).

    This isn't my photo but it is exactly what I am seeing on my machine:
    https://preview.redd.it/fzb8c5naia64...00197725c0e1da

    I tried to repeat the leak so I can see where it is leaking from with no avail.
    Tried to:

    Turn on machine and leave it
    Run steam wand
    Run water through group head - No pressure and with pressure
    Run hot water through the hot water sprout

    Has anyone had this issue before?

    The machine still works fine but sooner or later if I can't fix this I will need to tear apart the machine to figure out what is wrong.

    Thanks
Working...
