Worcester Bosch boilers have a reputation for reliability and efficiency. However, like any heating appliance, they do encounter issues from time to time. One such issue is the 9U 233 error code, which relates to a problem with the code plug in the Heat Control Module (H.C.M.).
This blog will guide the steps to follow with this error code.

9U 233 Error Code

Relates To A Problem With The Code Plug
Usually, this error code shows itself in a Worcester Bosch CDi Compact boiler and relates to the code plug within the Heat Control Module. The code plug contains vital information for the boiler's operation and performance. When a code plug error occurs, it will trigger the 9U 233 error code, which requires the intervention of a boiler engineer.

Initial Troubleshooting Steps

Seeking professional help
If the 9U 233 error code is encountered in a Worcester Bosch CDi Compact boiler, the first step is to call a professional Gas Safe engineer to reset your Worcester boiler. Sometimes, a temporary glitch or minor issue might trigger the error code, and a simple reset could resolve the problem. However, if the error persists even after the reset, that means there's something else related to the problem, and further investigation is required.

While attempting a reset might offer a quick solution, the 9U 233 error code often requires the attention of a qualified Gas Safe engineer. Gas Safe engineers are certified professionals with the knowledge and training to diagnose and repair complex issues in Worcester Bosch appliances for safety reasons.
