I installed a Franke geyser in September 2011, replacing an older kwikot (upon the advice of Builders Warehouse and what a mistake it has been). About a month ago I started having problems as it didnt heat the water... I replaced both the thermostat and element as they claim was that we had probably burned the element as it couldnt be set higher than 55degrees. I had both the element and thermostat tested and to my surprise nothing wrong with either.

It heated the water for 2 days and then same problem, so I unconnected the electrical wiring and reconnected it and wow to my surprise it heated the water within 20 minutes... A month later still the same, work for two day and then problems, I deconnect and reconnect and walla working again...

Not sure if anyone else has had this problem?
