What it is
The Worcester Bosch code plug 1105 is a configuration plug used on the Greenstar 25SI Combi boiler family. It tells the appliance's control electronics which gas type the boiler is set up to run on — in this case LPG. It is fitted to the control board and is checked or replaced during commissioning, servicing or a gas type change.
Signs this part needs replacing
- Boiler locks out or fails to fire after a gas type change
- Appliance is configured for the wrong gas family
- Code plug is missing, loose or visibly damaged on the control board
- Combustion readings do not match the gas being used
Before you order
- Confirm the appliance is a Worcester Greenstar 25SI Combi.
- Check whether the boiler is set up for LPG or NG — this is the LPG code plug.
- Compare the existing plug against part number 87144311050.
- Make sure the plug is seated correctly on the control board before deciding it needs replacing.
