The how to fix the FD error code on your Worcester Bosch Greenstar Combi Boiler below is informational and it is important to note that working on a boiler can be dangerous and should only be attempted by a qualified technician or heating engineer.

Step 1: Turn off the power supply to the boiler

Before attempting any repairs, ensure that the power supply to the boiler is turned off to avoid the risk of electric shock. You can do this by turning off the electrical switch or circuit breaker that controls the power supply to the boiler.

Step 2: Inspect the flame detection electrode

The flame detection electrode is responsible for detecting the presence of a flame in the boiler. Over time, it can become dirty or corroded, causing the FD error code to appear. Inspect the electrode to ensure it is clean and free from corrosion. If necessary, clean the electrode with a soft-bristled brush or replace it if it is damaged.

Step 3: Check the burner

The burner is responsible for heating the water in the boiler. If it is dirty or blocked, it can prevent the flame from being detected by the electrode, causing the FD error code to appear. Inspect the burner and clean it thoroughly using a soft-bristled brush or compressed air. If the burner is damaged, it will need to be replaced.

Step 4: Check the burner gasket

The burner gasket creates a seal between the burner and the boiler. If it is damaged or worn, it can allow air to enter the burner, preventing the flame from being detected by the electrode. Inspect the gasket and replace it if necessary.

Step 5: Check the ignition lead

The ignition lead is responsible for delivering a spark to ignite the burner. If it is damaged or worn, it can prevent the burner from igniting, causing the FD error code to appear. Inspect the ignition lead and replace it if necessary.

Step 6: Restart the boiler

Once you have carried out the necessary repairs, turn the power supply back on to the boiler and restart it. If the repairs have been successful, the FD error code should no longer appear, and the boiler should be operating normally.

It is important to note that if you are not familiar with the proper procedures for repairing a Worcester Bosch Greenstar Combi Boiler, it is recommended to contact a qualified technician or heating engineer to diagnose and repair the fault. They can perform a thorough inspection of the boiler, identify the cause of the fault, and carry out any necessary repairs or replacements to restore the boiler to full working order.
