    Sorry to hear you are having such problems mate.

    Are you running it off the water tank or is it plumbed in?

      +1 to not use Wifi switch unless rated for wattage.

      I have used A Wemo for 18 months plus here in Oz on the 10Amp Pro 700 flawlessly.

        Plumbed in , but regulated to 2 bar as per factory instructions.

        Would have have liked to get the Wemo as it’s got a slightly higher amp rating than the TP-Link but it would appear that they’re not making the 240v ones anymore.

          I have this same concern a couple of years ago when I first bought my 700. Initial startup time was a bit sluggish and recovery time was slower than I would have liked. The main drawback though was not being able to Steam and pull shots at the same time which is a main reason for having a dual boiler.

          I initially raised the issue a couple of years back on this thread https://coffeesnobs.com.au/brewing-e...pressions.html

          After changing the PID, I was running the machine on a 15a line for about 6 months before an electrician doing a seperate job assured me that a standard 10a outlet had more than enough overhead to handle the machine running both elements at once. We looked over the specs on the outlet, ran the machine and no problem. I double checked it with another electrician and have been running it on a 10a output for the last 1.5 years.

          I highly recommend the "15a" setting. The machine can pull shots and steam all day with no downtime or loss of pressure (the way the machine was intended to run)

          EDIT: a quick note on the Wi-Fi switch. I was running a 10 amp timer switch for about a year before it crapped out. Electrician said it wasn't made to as high spec as the outlet and would eventually give out and the worst that would happen would be it would just stop working (ie. no fires or explosion possible). I suggest you ask a professional and likely get a second opinion regarding the electrical side of things.

            Can not be recommended by any qualified person here I can assure you.
            It may not cause a problem in the short term but in the long run it may lead to insulation deterioration and then be at risk of causing a fire.
            Just NOT worth it...

              Unless you're a licensed electrician, your advice on electrical matters isn't useful. I had two seperate electricians advise me based on my conditions. I suggest OP does the same rather than listening to anyone in this thread.

              On the matter of constant steam pressure and stable brew temp. I can assure you that the upgrade to simultaneous heating is a worthy one. If your electrician recommends a 15a line based on your conditions, I'd recommend paying to have it installed.

                Very precise definition of who to listen to! As I understand Mail is an electrical engineer. I am not an english teacher but I believe separate is spelt with an a as a fourth letter - and I would be right.

                Separately, congratulations on putting forward a simple solution, which seems easy to implement. As you are aware the op is in NZ, I am not sure if they use the same variance ( +10%, -6%) as us on their 230v. As it seems switching to 15amp mode solves the problem, I would test while watching the machine, if that works just put the circuit in. Small cost to have machine working as you would want, combined with peace of mind.

                  Suggest you check Mals profile, you will find he is an electrical engineer.

                  Just had a look at yours, certainly didn't have to spend much time reading.

                    Not sure who he is, but AFAIK electrical engineer ≠ licensed electrician.

                    Indeed, which is why I hired a licensed electrician and would encourage OP to do the same.

                    @WindAddict
                    I'd recommend changing the 4 hole steaming tip for a 3 or lower. Even at full 1.4 bar pressure (I'm assuming you don't have the 2.0 upgrade), the default nozzle doesn't deliver enough pressure with the supplied tip. I use a 1 hole tip and it's often a little too strong, a 3-2 would be my suggestion.

                    Another neat change you can do to improve your milk on the 700 is to remove the plastic inside the steaming wand. I've found when the wand runs much hotter it improves the milk. It should be noted that the plastic insert is to stop the wand getting too hot so you can hold it while steaming, something I don't find useful. You can pop the plastic part back in if you change your mind.

                      I'm a licensed electrician in NSW, you can read my advice above in post #2, which 338 has summarised nicely in post #22.

                      Also, in my professional opinion Mal knows what he's talking about. Not only that but he's qualified to give advice on loading and circuit sizes. You're correct in saying an electrical engineer and a licenced electrician are different, Mal is not licenced to install a 15A power point for you, but he can tell you it needs to be installed (just like I can).

                      P.S. see if you can get your licenced electrician to give you the same advice they gave you above in writing. It will help with getting the insurance company to pay in the event of a fire.

                        Aside from your insulting tone, your ignorance in commenting on potentially dangerous practices is worse. Maybe less arrogance would be a good start when dealing with long term and respected site members.

                          Amen to that.

                            The 700 has a 1200W coffee boiler element and a 1400W steam boiler element.

                            1200W + 1400W = 2600W

                            Your 10A outlet can safely deliver a maximum of 2400W, which is a 10A draw. 2600W is 10.8A. Add to that the motor to run the rotary pump which draws around 100W (i'm assuming, full size motors in commercial machines pull around 200-300W and the motor in the 700 is a smaller one) then you're well over a full 10A loading.

                            If your electrician said that the machine can operate both elements at once with still room to spare, I would highly suggest using a different electrician for any future work.

                              Agreed. I have always been of the opinion that PM is the most appropriate medium for those intent on delivery of insults. I'll take one Mal over 100 dodgy sparkies any day.
