Error code 9U showing on your Worcester Boiler? This normally means there’s fault with the code plug, either it’s disconnected, faulty or there’s a problem with the wiring harness. First thing to try is the reset button but more than likely, it will require a Gas Safe engineer to attend to diagnose correctly and repair.

A 9U fault code display on a Worcester boiler is showing a problem with the code plug within then boiler. The most likely cause is it has been disconnected or the connections/wiring are faulty. As with most Boiler fault codes a Gas Safe registered engineer would need to investigate further to diagnose the issue.
