Modern tumble dryers display error codes to indicate specific faults. These codes are designed to make diagnosis easier, but many homeowners find them confusing. Understanding what each code means and the associated repair cost helps you plan and avoid unnecessary expense.

How error codes work

Error codes are generated when sensors or circuits detect a fault. The display may flash letters, numbers, or both. Codes vary by manufacturer, so consulting your dryer manual is essential.

Common triggers for error codes include:

  • Heating problems
  • Blocked airflow or vent
  • Moisture sensor issues
  • Motor faults
  • Door or safety switch problems
  • Control board errors

Typical UK repair costs per code type

  • Heating element fault: £110 to £190
  • Blocked vent or filter: £60 to £100
  • Moisture sensor replacement: £70 to £130
  • Motor replacement: £160 to £280
  • Door switch repair: £60 to £120
  • Control board replacement: £160 to £320
  • Call-out fee: £40 to £70

Most single-error repairs fall between £90 and £180.

Why multiple codes appear

Sometimes a dryer will display multiple codes. This usually means one fault has triggered secondary sensors. For example, a blocked condenser may cause overheating, which then triggers a thermal cut-out code.

Engineers diagnose the root cause first, then clear secondary faults.

DIY checks before calling an engineer

  • Clean filters and condenser units
  • Check that the door is fully closed
  • Inspect vents for blockages
  • Ensure the drum spins freely

Sometimes clearing the code after basic cleaning resolves the issue.

When repair costs can escalate

If the control board or motor has failed, costs are higher. Integrated dryers or older machines may require longer labour, increasing expenses.

Final thoughts

Error codes are useful but require interpretation. Most faults are repairable at reasonable cost if addressed early. Ignoring codes can lead to more expensive repairs.
