  • Re: Upgraditis: 2-group Grimac Commercial

    Robusto, to the hilarity of the camping community i have been known to sit on the roof of the bus with an array of syringes, each filled with a different colour food-dyed water.
    each of the  suspect spots gets a small squirt of one of coloured waters and whatever colour ends up inside the bus tells me where it comes from.
    polka-dotted window frames? sure, but they are dry now!!

    i visited the captain Tolleys website and found that the stuff is not available in Oz, other than directly from O/S supplier/manufacturer or the UK Bay of Temptations.

    good luck

      Great idea Lizzi! I guess you could also use some of the dye that plumbers use to trace leaks - wonderful non-toxic flouro green.

      Then again we might be talking about marine ply where just a few coats of marine varnish might help. Tell us more Robusto, or better yet, how about some pics?

        You must be quite a sight Lizzie. But as you say, it works.

        Unfortunately, I cannot find the suspect external points of entry to take the syringes to them. Just unbroken areas of white paint.

        Dennis, the boat is oil-based paint on the outside, and parts of the interior, plus clear polyurethane. If Im feeling energetic next spring Ill sand back and re-paint the outside. Maybe in the process the roof leak entry points will reveal themselves.

        • It's been some 5 years since I started this thread on the acquisition of my Grimac 2-grouper.

          Perhaps a quick update is in order.

          It still sits on the kitchen bench, next to the sink and taking up a lot of valuable real estate there.

          It's plumbed in to the water supply and the drip tray to the kitchen sink S-bend which also takes waste from the dishwasher.
          A couple of times, waste grounds have clogged that S-bend, so that when the dishwasher emptied, water had nowhere to go but up...up the small flexible hose from Grimac's drip tray.....spilling out all over the kitchen bench.

          The drip system is now regularly flushed to prevent reoccurence!

          The machine is very reliable, and consistent. I've replaced the group seals a couple of times. And attended to a sticking o-ring on the vacuum break valve a couple of times. Both very quick, cheap and easy fixes.

          Without intentionally doing so, we have cut back on coffee and alcohol use. Don't know why.

          So now it's switched on in the morning for a breakfast latte for me and Mrs Robusto....and mid-morning double shot espresso for me.
          It's then switched off until night for a single espresso for me, and latte for her.

          At Christmas and other family gathreings it is a godsend. I take orders for up to 20 espressos and lattes, and with the two groups I can made 4 shots at a time, flush, reload and extract with no waiting. The 5 litre boiler never goes cold or loses pressure.

          Steaming milk....we make a great team, and I must say, perfect microfoam has been second-nature for years. I look back at my first attempts with its predecessor, a Rancilo Silvia. Where do I hold the pitcher? At what angle to the wand? Tilt to the left or right, front or back? Do I move it or keep it stil?......It was a mystery whose secrets I feared would never be unlocked.

          But they were unlocked, and it's a pleasure to deliver my wife and guests microfoam which knocks their socks off.

          I should really descale it, perhaps think about a new diaphragm for the mighty Sirai pressurestat which never misses a beat. Perhaps even clean the contactors contacts. But if it aint broke, why bother trying to fix it?

          On the worry side, Grinders in Fairfield no longer stock parts. Something which may be more than a worry down the track when and if I need them.

          Looking back over this thread last night I saw recalled how JavaB and Sparky guided me during its set up. I remain indebted to them.

          • Nice to hear, I read over this today. I'm sure it's got a lot more life in it.

            What's the next upgrade?

              Next upgrade? Do they have coffee machines in heaven?

                  • I've just been given two group Grimac espresso machine. While I'm fascinated with espresso machines and want to learn more about them, I don't have a clue. I'm picking it up In the morning.
                    The lady that's giving it to me says it's not reliable. Who knows what's wrong with the thing. I guess free means I can't go wrong, right? I'll post pictures of the actual machine tomorrow. While I'm handy it's probably way over my head to try to refurbish the machine. Would love to have some feedback. Thank you
