F75 is several issues.
1. Blocked or faulty low pressure sensor.
2. Failed or failing pump. With the boiler in idle bring up the digital pressure display. - on the old type. Top right button twice on the new ones. Give the boiler a demand. You should get a 0.2 bar rise.
3. Which links into number 2. The old rubber hose connections are full of crap. Give them a squeez if they are solid replace. This causes the pump to work to hard and burn out. Personally I'd upgrade them to the new copper ones when you renew the pump.
