Rogue Water Urn
blog entry for Saturday, 12 May 2018
Wonders will never cease! I always seem to have trouble with kettles or water urns. Previously I had one that kept leaking all the time necessitating that water was needing to be wiped up on a continued basis.
Now while my current one is working well I have encountered an intriguing (and slightly annoying problem relating to it.
Namely, the temperature dial keeps moving up of its own accord (so what this means if you leave it alone it will just creep up over a period of a couple of hours so that the water gets to a boiling point and most of the water would evaporate away! My temporary solution is that I turned it off and only boil water when I need a cup of tea.
I'm curious as to what might be the cause of this problem?
