Does nest thermostat override immersion when boiler broken?

[Louise3]

Hello. Our Google nest controls both our heating and hot water. Our boiler broke down on Friday leaving me without both, however next to our water tank I have noticed a water heater switch. I’ve tried turning it on (light on switch turns on) but it doesn’t seem to work. Is it being overridden by the Google nest (currently switched off) and can it be easily resolved so that I can at least have some hot water? Many thanks for any advice!

Hi there @Louise3

Thanks for reaching out. Could you tell us please if the Heat Link is receiving any power? What is the color of the LED on it?
