Hello,
DIY requesting help with diagnosing problem
My mother's storage heater has developed a fault after turning it back on for winter.
It trips the Consumer unit rcd when power switched on.
Initially I thought most likely an issue with an element. I removed all 3 elements and tested resistance, one was 64ohm (ok) the other two were no good. So I got 3 new elements and measured those (ok). Fitted them and it still has the same issue.
I have also checked the wire from the wall switch to the input at the bottom of the heater.
Further to this if I turn the input charge stat down it clicks off and I can switch it on without tripping, when I turn it up it clicks and trips out.
I run out of time today and had to leave it, also being a heater on a timed circuit it only had power for a few hours in the afternoon.
Would this likely be a problem with the button cutout switch or the stat, would they usually cause that problem when they fail?
Do I just bypass them for a test only, by disconnecting and linking the switched live at the stat/cutout to see if it stops tripping the RCD
It looks like the stat and cutout have been superseded by an all in one stat/cutout kit. Don't want to buy it until I know its needed.
Thanks

- TL;DR
- Storage heater trips RCD, new elements fitted, still have issue, could it be input stat/cutout.
