HELP No power to my boilermate 2000

Hello, I hope someone can point me in the right direction.
My boilermate 2000 is just over 10 years old and we have never had any issues with it. Yesterday we realised there was no hot water. Today I have checked the boilermate and the power light on the front is not on. We have no heating either. I have done the obvious and tried powering off and then back on which has made no difference. What would you suggest is the issue???? im hoping just a fuse. Many thanks Lisa

Check the main ACB
Big PCB inside the unit.
It may have failed.
Read through the posts on here, lots of info ref your unit.
And you will, well I hope learn a lot.
