All,
I am on Domestic 10 elec and so my immersion tank heats the water
overnight. Yesterday I noticed that the water was cold after only a
small amount had been used, I checked the fuses etc and evrything seemed
OK. So, I put it down to using a little more than we thought and hoped
it would be hot again this morning - its not !
So, how do I go about testing the element to see if its dead ?? I am
competant with a DMM but what I am wondering is how these things
normally show they are dead - will earth short to neutral / live, will
the live/neutral resistance go up to infinity ?? If I can do this simple
test myself I can call my electrician I *know* whats wrong rather than
ask him out it tun out to be something else (like what ?!?!).

Thanks in advance,
N.
