The Ideal Icos boiler has many problems, the most common being faulty controls.
If you have power to the control but the display is blank or there is a sunken area on the plastic casing, the chances are your control is faulty and needs changing.
With the orange v9 control the boiler maybe operating but with no display, again this is a common fault with the control.
Sometimes the failure of the control is down to the failure of the fan. A good sign the fan is faulty, is if the fan just judders back and forth without spinning.
