Not nessecarily. A loose neutral in a shower switch can smoulder for months undetected.I agree that there could be an electrical fault in the wiring, but that would more likely trip the RCD and/or MCB.
I have low pressure from my electric shower.
That's flow not pressure.I have read kevnurse's instructions about turning the shower to cold and to see if pressure increases. I tried this and it did. when i decrease the temperature the pressure increases.
Now i know what the problem is but i need a little advice on how to fix it.
