      Hi there

      From my reckoning and brain racking here I seem to remember coming accorss this problem before and the end result was to set the two thermostats at differing temperatures such as the bottom one at say 60 Degrees C and the top one at 50 Degrees C – given that the top one is only really a booster element anyways and will only readily heat the top section of the tank to provide a little hot water quickly – the bottom element is the one that really does all the work. If you set both stats to the same temp the top stat will run into overheat once the bottom thermostat reaches temperature due to the fact that hot water is les dense than cold water and rises to the top thereby overheating the top thermostat sensor.
      Give this a spin and see how you get on with it – let me know how it works for you will ya????

      I think Peter is on right track, but also make sure the sluge is cleaned out of bottom of WH, while you have lower element out look and see if it is clear,I use a wet vac with a piece of water hose tapped on and clean mine out that way. let us know.
