I switched the electricity off by accident on my boiler, now i've put it back on, you can here a noise when you plug it in but theres nothing coming on the small screen to say its working. I've phoned the gass and the boiler company but i havent got after sales care so they wont help me. I dont think theres anything big wrong with it, I haven't had any problems up to now. I was hopeing theres just some button I have to press just to restart it. Its a WORCESTER HIGHFLOW 3.5. The screen is blank, so i dont know if its working or not. { the pilot light is on.}

had the same problem with my highflow 3.5. Mine was resolved by leaving the mains power turned off for 4 hours, the problem was the LCD display on the timer, allowing it to stand unpowered for a while and i guess discharge meant that when I turned the power back on the display resumed as normal, and i was able to reprogram it. I've had to do this a number of times always after a power cut.

I do not have this model (a different highflow), but the following may work:

Remove the access cover on the front (usually lift and tilt at the top). You should gain access to the underside of the control panel (the bit with the screen and buttons), but you may need to move a couple more covers. Once you have done this look on the underside of the controls. You should see on the right hand side a small circular red housing. In the centre of this, there should be a small button. Press this, and it will reset the safety cut-off (which can go by accident when turned off).

Failing this, it may be the internal fuse. You will need to read your manual to see how to gain access to the top of the panel, and there should be a small clear fuse somewhere. Replace this.
