          Gday Mal - so its reliability over the longer term that they are chasing? I suppose if I was ever brave (silly? ) enough to open a shop and take the old girl with me as a second machine that would be a compelling reason to do the mod.

          Cheers and thanks

               Is a coffee machine any more likely to blow out water wise than a dishwasher say?
              It all depends :-) How long is a piece of string ?

              Thanks for that Piccolo Late.

              I understand that flooding can happen, but what I am saying is that no one (no one I know of and I bet its less than 1%) turn off the tap to their dishwasher when they go out for an hour (and its just as likely to happen if your out for an hour compared to 2 weeks on holiday really) so likewise they wouldnt do it for a plumbed in machine...

              Cheers
              With most if not all Dishwashers and Washing machines they use a N/C solenoid valve in the water inlet lines; to manage the risk of flooding..

              Mind you it is still not 100% but much better than nothing...

              The risk is where the solenoid valve fails (remains closed) when you want to use it... For most dishwashers and washing machines... They want to see a flow rate and or water level before running... With the washing machine, there is usually NO heating, as that is from the hot water tap... Dishwashers are different and I have seen some old ones that would blow the heater element if the water level detector was not working correctly.

              Thus with coffee machines... It again comes down to what to you want and how is it made. I have seen some commercial units that are plumbed in, with the inlet having a N/C solenoid. But I can not comment for all or for home units that are plumbed.

              Thus depending on your config and setup, you could end up with a FLOOD or having pumps and heaters coming on with NO water...

              1: I power off when no intention for a coffee for a while.
              2: Tank... So no issue with water at this stage.

              As KK said... When you use the power monitor... You soon wake up to the consumption of power and teh costs..

              At teh end of teh day.. Attilio first post covers it quite well.

                I think JavaB worked out what is LM 2 group cost to run (with no lagging from memory) and it was $1 a day left on 24 hours. With lagging you could get close to halving that. When you consider how reliable well built commercials are $183 odd a year in electricity is nothing particularly if, as we do, you are pulling all the hot water out for tea cups and tea pots....ie you would have to take off the $183 the not insignificant cost of running the kettle 15 times or so a day (we are big tea drinkers aswell as coffee).

                Thanks for the info re flooding AM. Is there a way to tell what the set up is for mine re NC/Solenoid by looking at it...what am I looking for and where ?(or just stop worrying after reading this thread and turn the water off when going away for more than say a day (ie if going away for a weekend or longer, do like I always do and turn it off).

                Interestingly this has got me thinking about why there are no grates in the kitchen floor as standard. I might stick one in (highset house) and that takes care of many potential problems).

                Cheers

                  Re: Whether to turn home machines on and off or leave on all the time

                  After seeing our old Brasilia 3 group at work bite the dust due to a fault that occured over night, everyone who works there with their own machine at home turns it off once they are done with it. Our new work machine has a timer set into the switchboard for it to kill power at 10 pm (when were done for a night shift) and to bring the machine back on at 7am.

                  My boss got told when it happened to install the timer, if only because "when the sh!t hits the fan, you want someone to be standing there to deal with it".

                  Sadly twice now that person has been me :

                  Plus it doesnt take long for some machines to heat up, mine goes from stone cold to ready in 30 min, so I can wake up, turn it on, shower & dress then have coffee

                    Visually you can... but depending on access it may or may not be so easy...

                    A plumbing and or electrical schematic should identify any N/C or N/O valves in the inlet side.

                    As to floor grates.. Well ya need to make sure it is in the lowest point :-) May or may not be so easy.. if done after market.

                    I have not got one in the kitchen... But Bathrooms / Kitchen and toilets are done... Tried to have two in the garage but due to last min hitches did not even get to have a slight slope... This washing / cleaning the garage floor is a right pain.

                      Re: Whether to turn home machines on and off or leave on all the time

                      My machine isnt plumbed in; thankfully after this mornings discovery.
                      My wife mentioned shed boiled the kettle because the Expobar wasnt showing pressure on the gauge (shes learning).
                      First look; the clock; 10:15 (we were out at a 50th birthday party last night at a popular city pub that has live (loud) music).
                      Machine is on a timer and I remember filling the tank.

                      I get to the kitchen to start analysing the problem.
                      Tank definitely not full.
                      Spot water on the bench; lots (damn!).
                      Aha!! Leva is up.  >
                      I think the Alzheimers is getting worse.
                      I must have left it up when giving the front a clean; it was due for its full clean yesterday but being the long weekend I gave myself a reprieve until today.
                      Drip tray was full to overflowing.

                      I dont remember how much water was in the tray previously but luckily it must have not been much.
                      The tank is 3L but the low water cut-out switch operates around the 1L mark, giving 2L usable until the tank needs refilling; the drip tray holds 2L.

                      If the tank hadnt quite been as full or the drip tray had been empty, Id have gotten away with such a silly mistake.

                      DAMN DAMN DAMN! (file in "Lessons Learned")


                      While Im here, coincidentally we installed a new dishwasher this week.
                      The first cycle didnt seem to work.
                      Turns out Id forgotten to open up the tap again after connecting the water hose (Alzheimers again?).  :-[  :-[  :-[  :-[  :-[

                      My boiler is up to pressure faster than the jug (2 minutes) but it takes a while for the rest to heat up properly.

                      To touch, the group head can feel hot enough after 30 minutes, but attempting a shot doesnt result in the best coffee.
                      Thats why its on a timer for at least 1 hour before I get up (go back to line 1).

                          I wish Working all weekend (playing with toys) currently hailing outside anyway so may as well work

                          Data sheet for anyone interested in a bit more info on the SSRs too http://www.cosmo-ic.com/object/products/KSD240AC8.pdf

                            When you hardwire an SSR into the heating element circuit, do the pressurstat contacts cut-in in the event of an SSR failure or are the contacs bypassed altogether??

                              Mate - Mal and AM would know better than me. The way envisage it working the switching of the closed circuit via the pressure stat switch would only send a low current trigger to energise the SSR which in turn then switches on high current (ie full normal current that used to run from the pressurestat switch before installation of the SSR) to the boiler element. So as I see it being set up if the SSR failed there would be either power all the time to the boiler or no power at all to the boiler depending on whether the SSR failed open or closed (it may only be able to fail to one condition I dont know).

                              Cheers

                              PS. Hopefully someone more skilled than I will chime in

                                The contacts would be used to activate or trigger the SSR. If the SSR failed then there would be no power to the element.
