Did you run the taps to remove any air from the system (after making sure the drain valve on the water heater is closed). The first time I used mine (on EHU), I had a similar problem, it overheated due to an airlock, and a thermal cutout kicked in. No amount of resetting on the control panel would clear the lockout. Just had to wait for it to cool down again, 20-30 minutes I think it was. Then it just started working again.

I can’t really suggest anything further, but when it happened to me, switching the PSU off and back on again did not clear the fault. But, I did have another odd thing happen once. I was on hookup and the water heater was on, then I switched on the space heater which ran for a couple of minutes then stopped with a lockout. It would not reset on the control panel, I tried a few times. Running out of things to try, I switched off the water heater, and the space heater lockout disappeared. Then I switched both back on, and they ran normally! So I’m not sure what that demonstrates except those circuits are not necessarily as independent as you might think. Or it’s a bit glitchy.

Incidentally I know it says to switch off the PSU before connecting the mains, then switch it back on again afterwards, but I generally don’t, not on UK mains anyway. I wonder if most people do, or don’t. My reading of that is that it is more important on continental hookups where reverse polarity is a possibility. I’m not suggesting you shouldn’t carry on doing it though, maybe I should be too!
