Grant 26e oil combi; power lost yet mains supply OK

[mgmidget]

My Grant 26e combi has mains electric power, the LED on the power rocker switch is lit, yet the power LED on the control panel is off. As a result we have lost heating and hot water.

Any ideas?

Thank you.

Tony, thanks for the reply. The fuse in the isolator switch is OK, deduced by the fact that power light on wireless theromstat sensor is on and the LED on the ON/OFF rocker switch is lit.

Is there another fuse within the boiler? Where?

Thanks again.

Ok, are you familiar with pressing to overheat button on the front panel under a black cap? Also the burner lockout button which is located inside the boiler which might be illuminated red and require resetting by pressing?

If there is a fuse, it will be a glass 1.5 amp. I only install Worcesters, so not sure.
