The unit has been excellent saving a lot of money over the past 6 years. It's running on off peak overnight as we have a premium Feed in Tariff. The big problem though was we got an E124 error. However it was easily dealt with. Pure Electric gave us the option of paying $550 for a changeover motherboard but also gave us information on what needs to be fixed which is a capacitor ZIG, T1522, PET, 105 degC, 35v, 470uF Low ESR. We were able to get a new one soldered in at our local mobile phone repair shop so it only cost us $100 (I believe the capacitor is worth around $10). Thanks for Pure Electric for sorting this out. I read a lot of comments in these review sites and forums that it is unfixable but Pure Electric has helped fix a lot of them by simply getting the capacitors swapped. Explanation they gave is that Australian grid voltages are too high especially in areas with a lot of solar and the same capacitors are dying because of it. Same thing is happening to many high end german induction cooktops and ovens.
