What it is
The code plug 1138 is a small configuration component used on Worcester Bosch Greenstar Junior combi boilers. It tells the boiler's control board which fuel the appliance is set up to run on, in this case LPG. Fitting the correct code plug ensures the control electronics apply the right operating parameters for the fuel type.
Signs this part needs replacing
- The boiler does not fire correctly after conversion to LPG
- Combustion readings do not match the expected values for the fuel type
- Fault codes relating to fuel type or combustion setup appear on the appliance
- The boiler locks out following control board work or a fuel conversion
- The existing code plug is missing, damaged or fitted with the wrong reference
Before you order
- Confirm the appliance model against the fit list above
- Check whether the boiler is set up for LPG or natural gas, as the code plug differs by fuel type
- Verify the code plug reference 1138 matches the one required for your appliance
- Inspect the existing code plug and its seating on the control board before ordering
