Professional inspection is recommended.

Urgency

High

Quick answer

F68, or A68 for a permanent lockout, indicates a BCC Service key file loading error on the BlueHelix Pro. This is a technical operation involving combustion settings: contact the service engineer and do not experiment with keys or files.

Safety first

Stop and check this first

  • If you smell gas while F68 is displayed, leave the home without operating switches or creating flames or sparks; call the gas emergency service from outside. Do not use the boiler again until the situation has been assessed.
  • With F68, a CO alarm or headache, dizziness or nausea calls for moving into fresh air and seeking urgent help from outside; the absence of a gas smell does not rule out carbon monoxide. Do not stay indoors to try a reset.

Safe checks you can perform

  • Identify F68, A68 and the previous service work
  • Leave BCC loading to the authorised service
  • Give the technician the specific diagnostic record

Leave these tasks to a qualified professional

  • Do not attempt this professional task: Repeat loading within the specified interval
  • Do not attempt this professional task: Establish whether the service key needs replacement

What a technician must be able to justify

Technician visit

These are the steps they must carry out and show you. Tick them as they work: if steps are skipped, do not accept a part swap.

These are not instructions for opening or handling the equipment yourself. They are the checks that should support a technical conclusion.

  1. Repeat loading within the specified interval

    What they doAn authorised gas technician repeats BCC loading within five minutes after powering the boiler, following the kit instructions referenced in the appliance manual.

    They must show youthe result of repeating the BCC KEY procedure.

    In writingthe procedure used, compliance with the five minute interval and the final displayed code.

  2. Establish whether the service key needs replacement

    What they doIf loading still fails, the authorised gas technician assesses whether to replace the BCC Service key as the fault table permits and checks the subsequent loading result.

    They must show youthe loading failure that led to inspection or replacement of the BCC key.

    In writingthe work on the service key and the parameter loading result.

Before accepting a part or repair

Nothing has been shown yet. Do not accept a part swap based on the code alone.

Follow these steps

Note: Follow the documented order. An error code identifies the affected system, but it does not prove by itself which part has failed.

  1. Identify F68, A68 and the previous service work

    No special tools

    Who:
    you, reading the screen and available service paperwork.
    How:
    note whether F68 or A68 appears and whether the paperwork records an electronic board replacement or a BCC KEY loading operation.
    Result that matters:
    the file warning and the service operation that needs review.
    If a board replacement record exists:
    pass it to the engineer with the code.
    If that history is unavailable:
    still report the warning without assuming the board was replaced.
    Evidence to keep:
    an F68 or A68 photograph and any relevant job record.

  2. Leave BCC loading to the authorised service

    No special tools

    Who:
    you, without handling service accessories.
    How:
    retain the F68/A68 indication and contact the engineer; do not use a BCC key or attempt to load board files.
    Result that matters:
    combustion parameter work remains with the professional.
    If F68 appears:
    report the F prefix, which denotes a temporary lockout.
    If A68 appears:
    report the A prefix, which denotes a permanent lockout.
    Evidence to keep:
    the sequence of prefixes seen before the service visit.

  3. Give the technician the specific diagnostic record

    Tools required

    Who:
    an authorised gas technician.
    How:
    match the model to the F68 fault row and perform the professional checks set out below.
    Result that matters:
    an explanation of F68 based on inspection rather than the display alone.
    If the fault is established:
    correct the documented cause before concluding the visit.
    If it is unresolved:
    record the outstanding diagnosis without assigning a failed component.
    Evidence to keep:
    the F68 inspection report with findings and work performed.

    F68 inspection involves internal components; the user must not remove the casing or make electrical or gas connections.

What it means

F68 and A68 share the BCC Service key file loading error on the BlueHelix Pro RRT 24 C. The manual explains that BCC KEY updates combustion parameters and is used when replacing the electronic board on certain models. The fault table calls for repeating the loading procedure within five minutes of powering the boiler and replacing the key where appropriate. This warning does not independently establish a defective board: the loading procedure and service key require professional assessment.

Warnings and stop conditions

  • Criticaleditorial warning

    If you smell gas while F68 is displayed, leave the home without operating switches or creating flames or sparks; call the gas emergency service from outside. Do not use the boiler again until the situation has been assessed.
