No hot water, new thermostat!!

[LeeUK]

Hi

I have a Heatrae Sadia and the immersion hasn't worked for a while so I replaced the thermostat and still nothing

Are these stats straight forward to wire up, it seemed it when I did it, just wondering if the last one was wired up wrong way, there is power.

Any ideas?

Is the re-set button pushed in?

have you thought that the thermostat was working fine & the immersion is knackered
