Hi,
My immersion was tripping. I isolated it.
I have a sink/bath switch, with a digital 7 day timer off it.
I opened the sink/bath switch and all looked clean and tight.
I took the top off the immersion heater, and it was full of water.
I turned off the cold feed and I drained a few litres from the hot taps, it started to stop flowing from the taps relatively quickly.
I managed to carefully remove the element.
The tank was still nearly full of water! I think my cold feed gate was not closing fully. It was messy but I managed to work around this.
I went and bought a new element of the same size.
I cleaned up the area (there was paste and a dry broken gasket). I used a file on the surface.
I fitted it but there was the tiniest of weeps.
I refitted it with a new gasket and (sadly) smeared a small bit of Tec7 around both sides of the gasket. The weep is gone.
I opened the cold feed again.
I rewired it up, comparing to the photos I took of the switch insides.
I turned the power back on and turned on the timer.
The red light came on and I heard the immersion 'hissing'.
About 30 seconds later it just turned off, but no power trip.
I found that my timer had a stray 'off' setting at exactly the time that I had turned it on, by fluke!
I turned it on again and the red light was on, but I noticed it was not hissing. I put this down to the new one being new!
The next day my kids are complaining it's not working, and indeed it's not.
I have checked the visible reset button and it seems to be depressed.
There is water coming out of the hot taps. But it's only residual heat from having the central heating on (I was fooled but this when testing)
Looking for advice. As you can see I'm somewhat competent but I'm not super knowledgeable, especially with electrics, I can do it all but would need guidance.
At this stage I'm thinking:
- When I wired it back to the switch something has come loose. I can check this obviously
- There is an airlock or something. But I don't really feel any heat from the tank (the insulation is scraped away from some of the top, so I genuinely think it's not heating it
- There is something wrong with the wiring in the element
- The element needs to be reset somehow even though I think it has
- The element is just faulty
Any guidance on what to test and how is greatly appreciated.
