Firstly is the breaker which is tripping an earth leakage breaker?
Secondly did you let any (and by any I mean just a few drops) of water / decaling solution get near the ends of the element (where the white ceramic bit is..... is so it "wicks" up into the ceramic and causes a leakage path to earth..... and trips the breaker. To test this put your meter on the highest ohms range ( say 20 Meg ohms) and measure from the outer sleeve to where the power connects - it should be open circuit... if not - thats your problem. Do this with the leads disconnected both ends (and of course power off!!!)
Check that first before changing anything else.
