Hi, have one of these shower units which has suddenly started running at significantly reduced heat, no other symptoms and unlike some of the previous questions, although we live in a small village and are subject to frequent power cuts/brown-outs, I can't tie in the recent problem with the shower to any of these.



Since having the shower we have had the heating element/can replaced 3 times, each approx. 1 year apart and at a cost of £90-ish a go this is fast becoming unreasonable.



The price of your replacements are better, but of course I'll have to replace it myself. (I can do this).



Anyway to the actual question; is there a conclusive test to confirm that the heating element has actually gone or at least one of the two within the can? A basic continuity check on both elements gives me a dead short which I'm assuming is correct, I have also tested the TCO on top of the can (as per your video) and it too shows up as dead short (no resistance in either case).



Don't want to pay out another £70-ish without being certain.



The previous 2 times (Triton engineer) the wiring had overheated and burnt out (from mains in junction block to heating element), this was replaced each time, this time this has not happened.



Was actually starting to think there was a design flaw, but a scan across the net didn't reveal anything.



Sorry for the ramble, but I'm beginning to think a replacement might be the best option.



Any help/pointers would be much appreciated.
