  • Replacing hoses on VBM Domobar Junior

    I've had my machine for over 10 years, last year I completely serviced the grouphead and the machine is functioning great. Making really nice coffee with my Niche Zero grinder.

    I clean out the water tank regularly, however, I want to address the hoses/tubing from the water tank. It almost seems like here is some mould inside of them. I haven't replaced these since we bought the machine.

    Not sure what the funky yellow stuff is. But they've gotta go!

    Any ideas what to buy? I've heard length is massively important for heat exchange machines. I clearly can't get the OEM hoses and filter. Anyone know where I can buy from? Looks like Coffee Parts have stuff but once again, no idea what to buy.

    Any help would be greatly appreciated!

    Anthony are your photos uploaded here or to google? They appear to link to google and are coming up blank for me. Uploading here is usually best, especially for longevity

      Measure the inside and outside diameter of the silicon and there's your solution. CP should be able to assist.

      It's probably 4x7 or 5x8 I'd think.

        What about the length? The ones on CP all seem to be 1 metre long! Also, what about the filter at the end of the tubing? Haven't been able to source a replacement for that.

          Does anyone know where I can buy another filter like the one on the end of one of the hoses in the photo above?

          I actually think what I currently have is about 2x4 which is interesting.

          The overall diameter appears to be around 0.4cm.

          Hmm, not sure what to do. I guess I'd prefer to replace with exactly what came with the machine. Any thoughts?

            Anyone got any advice here, why is the diameter of the hoses in my machine so much smaller than what's available on CS! Is it bad to change the diameter? Could this damage the part or the way a HX machine works?

              Just so that I am totally clear here the inside diameter of your hoses are 2mm correct? I had a VBM Junior 12 or so year ago and I don’t remember the hoses being so thin. It’s not that I am doubting what you say it just seems??? ultra narrow…

              My VBM junior has 5mm ID x 8mm OD hoses.

            Possibly iron. Try soaking the hose in a 5% solution of oxalic acid (available from hardware shops as "Diggers Rust and Scale Remover").

              silicone hose and filter should be available from Espresso Company Australia - 1300326326 - and they can freight it to you!
