This is a SURE SHOT Solution for F40 problem.... thanks to Paul Barker.....

If you get f40, hold in the reset button for approx 10 seconds until ts appears. Then press the reset button again. P-01 should flash. Press the top + button. Then press the minus button to change the parameters. You should then see 00 appear and the boiler may kick in if the water pressure is run on a switch. If it is run on a sensor you will need to press the top + to get it to 01. The boiler may again kick in if it's run on a sensor. If the boiler kicks in hold the reset button for approx 15 seconds to set these as the parameters.

Also... if 01 is not working and the LCD is still flashing.....then put it to 00 and then press reset button for 10 seconds.... it will definitely get sorted.... thats how i did mine...
cheers

I thought pressure needs to be at 1. Try bringing pressure down lower and then switch everything off electricity supply and then restart

before you refilling the system make sure it is off and cold , then refill the pressure to 1bar, with the power off,  turn the power on and wait for the boiler to modulate and see.
