I lost my element at the weekend and of course being me I looked at every which way to replace it without going down the simple root of buying a stock replacement.
The issue started with the RCD tripping in the fuse board in the house after descaling the machine. I checked the resistance and it was fine for the 1Kw rating (50 ohms on 230v element). What I did not check initially was the insulation resistance (leakage between the element and effectively earth). That was below 0.5 Mohm at room temp. (not accurate on a multimeter but good enough). I tried to improve matters by running it on a none RCD circuit, it worked and the IR came up to 2-3 Mohms. But this morning it was tripping again. Finally found the problem, there was a tiny pin hole in the sheath and by descaling it must have holed it and contaminated the element/ammonium hydroxide and killed it's insulation properties and tripped the RCD as the current to earth was over 30mA. Quite a detective story.
Anyway I have stripped down the heater to the base plate and managed to cleanly remove the element sheath. I found a heating element out of a pump machine which appeared to be ideal (and I had one) but problem was the original holes are too close to the edge to get a nut onto the ferrule. I am now looking into re-manufacturing the element onto the base plates Just to get an idea, how many of you have failed elements (one element/2 element types in pressed steel, forged steel, 110v/230v. How many Pavoni's are out there sitting unloved and dead, with the screw on bases??. I have now asked a couple of manufacturers of elements. Has this been looked at before? Anyone doing this? Any comments?. Would anyone be interested in a re-manufactured part at a significantly lower price? Bulk buy?
