There are also a number of error codes that typically show up on Worcester Bosch boilers.
Gregor Heating’s expert explained: “With most Worcester Bosch boilers, the first step is to consider the fault errors.”
Locking error: This will show a flashing fault code. A warning triangle is also likely to show up.
According to Gregor Heating: “You will need to press the reset button to stop this.”
Block error: In the event there is a blocking error, no data will be shown, but your boiler will stop working.
The expert said: “You will be able to find the cause code by pressing the spanner or return button.”
Cause code: This will show up as a three-digit number. According to the experts, you can find this by pressing the spanner or return button on your boiler.
Fault error: This will show up as an alphanumeric code. Gregor Heating states this code “will indicate the error by showing the fault group.”
These typically vary by boiler make and model.
Maintenance code: This begins with an H and “will tell you that there is an issue that will not stop the boiler working but will need the attention of an engineer”, according to Gregor Heating.
