  • Leaving a 15 amp machine running?

    Thinking of picking up a small single group 15 amp espresso machine tomorrow.

    Since I have no way of putting the machine on a timer I wonder if leaving the machine running 24/7 is the best way to go.

    Turning on my machine in the morning to let it heat up before I brew is not an opinion for me.

    Yes- you can leave a commercial on if need be.

    It may be worth looking at boiler insulation if not present to decrease your heat losses/power usage.

      Yes you can do it.

      Yes you run the risk of problems occurring overnight that would not be fun to discover in the morning.

        You havent mentioned the type of machine so can only go by your pst.

        On face value seems the machine really isnt fit for your purpose.

        Again on face value, not sure about your descriptions. Most "regular" 1 group commercial machines are 10 amp (talking Oz). A 15 amp machine would not be "small", in that if the boiler size was such that a 15 amp element was required for a normal heat up and recovery time, it would be pretty big. If its a "regular" size 1 group machine, fitting it with a 15 amp element will accelerate the ramp up time aggressively resulting in the probability of the thing overshooting markedly as it cycles. A sure fire coffee burning machine. So...its more likely a 2 group machine with a 15 amp element, or a 1 group machine with a 10 amp element.

        I could be wrong, but it is a more likely scenario, unless of course it is a genuine 15 amp 1 group machine as designed and built and hopefully well controlled. Not all machines are well controlled.

        Even 2 group *compact* machines are usually only 10 to 12.5 amps.

        For the rest of it. Used machine (?), older (?), more likelihood of an old flexible inlet water line failure at some point, not good if the machine is left on 24/7 and the pipe bursts whiile you are either asleep.....or at work, either way flooding out the house while you are not there to turn it off quickly.

        Ergo: Should I leave my machine running over night? Not unless you can afford the repair bill (not just yours but the neighbours if you live in an apartment and share the floor with others) when the flood eventually occurs.

        Yes I have seen it, and I have also seen a repair bill for $18,000.00 when the water made its way into the lift well and buggered up the hydraulics for the building elevator.

        Hope that helps.

          What's the deal with the 'no timer'? And what machine is it?

                Being 15A, I assume you have or will need a dedicated circuit in the switchboard for the machine. Why not install a DIN rail timer in the switchboard such as this one?

                  Any machine that pulls 15 amps is not a home use machine and either it, or the home (if that is the situation), will need some kind of mod to make "it" work out.

                  Ergo, not fit for purpose.

                  Far simpler to source a machine that will work on a 10 amp circuit and doesnt require a water or DRAIN connection, plunk it on the bench, fill the reservoir with water, plug it in, switch it on, wait for it to warm up, and make coffee straight up.

                  Thats not the only way, but it is the easier way.

                    ...thats a 125 volt , 1800w , rated device....for USA consumers.

                    and what is the concern about flexible water lines bursting ?
                    when did you last worry about any of the flexible water lines to the taps in your house bursting ?
                    or the dishwasher feed, or the washing machine ??
                    Every house has several of those (most taps ?) and I would guess most of them are older than this machine.
                    .....but a sensible installer would fit a new $10 flex hose anyway when re installing a machine.

                      This is about coffee machines (or the types of flexible water lines supplied with / fitted to). I dont know much about other flexible water lines, and you are prefectly entitled to do whatever you like including sticking your head in the sand.

                      Just in case you missed it above:

                      I've seen it several times on coffee machines over an extensive career in coffee and machines, and in addition to the $18,000.00 example from a failed water line to a coffee machine, I also saw an occurence where a water line TO A WASHING MACHINE failed, resulting in the entire floorcoverings in a house being written off. Big inconvenience factor besides cost.

                      And of course, even an occasional NEW flexi line is FAULTY. Seen that too, bursting the next day or the day after that...

                      In a cafe, where the line should only be pressurised while people are working, if there is a failure, staff are there to catch it and turn off the stop cock. Nothing much is damaged or lost when its only been running a minute maybe even a few.

                      But that is not the case when lines are left pressurised over night and over weekends when no one is in attendance or in the case of a home, when people are at work, and the leak goes unnattended for hours or days....

                      Just because it doesnt happen often, doesnt mean it doesnt happen. Are you next?

                        Sound advice. I've just plumbed my Duetto at my office and we turn the water off at the cock each night - I can't begin to imagine the damage it would cause to a CBD office building if it leaked overnight.

                          It's called "paranoia " ...
                          It's a fair bet every tap in that building has a flex water pipe connection of similar quality to that on your coffee machine.
                          Do you plan on turning off all those isolation taps also ?
                          And washing machine hoses are usually rubber with plastic fittings (Chinese produced ?)
                          How about that water/ice making fridge, usually supplied by a 6mm nylon tube with push fit (John guest) connections ! Boy are they scary !
                          i worry more about all those flex plumbing fittings that were installed 10+ years ago by some untrained plumbing apprentice on a Friday afternoon.
                          Please try to keep things in perspective !
                          Sure, leaks CAN happen, but the probability of it happening is much lower than other possible events.!

                            I'd be fairly certain that machine runs at 10 amps like my very similar Saeco Aroma (almost the same machine with different panels). Googling shows 1 group elements for these are 2500W. And timer switches are readily available for 15 amp circuits and above - I've worked on many commercial machines that were set up with an external timer switch where the machine was drawing as much as 30 amps. If a hardwired external timer switch was set up to run a machine, there's no good reason why you couldn't have it also switch a solenoid valve so that the water supply is also switched off when the machine is switched off.

                              Not sure if this helps your case. I run a 15A 2-group machine at home plumbed to a 10L Brita filtered cask. This could alleviate your water-burst fear.
