I got the F75 error code and researched solutions and causes. The answer seemed to be either the pressure sensor or the pump. The cost of a pump is about 200-250 so I took a chance that it was the cheaper option. I ordered the sensor and it was here the next day. Fitted it a day or so later and the problem is solved. Some tips when messing with the boiler…. Turn it off and drain it. This muppet forgot to drain it🤦‍♂️ so ended up with a lot of water in my face. Also damaged the PCB so had to replace that too. Managed to get a PCB for a good price too. All in all, replacing the sensor and PCB myself cost less than a heating engineer call out fee so I’m a happy chappy. Also learned how to drain the boiler for any future events.
