Hi, I have a De Dietrich MPX 24 Compact boiler showing an error code 128, the control panel is flashing with this code. I have googled this code, and it's showing me De Dietrich error code 128 is typically a flue pressure fault, which can be caused by blockages, high winds, or issues with the pressure switch itself. A persistent error may require a technician to inspect the flue, pressure switch, and tubing, though you can sometimes resolve it by checking for obstructions, ensuring the flue isn't exposed to excessive wind, or by resetting the boiler. I have done a reset on the boiler, and this has not helped. I have checked the flue and there is no obstruction. I have tried to reset this myself, and nothing is working. Does anyone have any ideas on what I could do next without having to call a professional? :(
