How to fix Ideal Mexico HE fault code F48

What does the Ideal Mexico HE F48 fault code mean?

The F48 fault code on the Ideal Mexico HE indicates a condensate fault, which typically arises when the condensate drain is blocked or frozen. This prevents the proper drainage of condensate water, leading to system shutdown to prevent damage.

Common Causes

  • Blocked condensate pipe: Debris, dirt, or ice can obstruct the condensate pipe, preventing water from draining away.
  • Frozen condensate pipe: In colder temperatures, the condensate pipe may freeze, causing a blockage that triggers the fault code.

Can I fix it myself? (DIY)

While you can attempt to clear any visible blockages in the condensate pipe, it is highly recommended to call a Gas Safe Engineer for any gas or electrical issues to ensure safety and compliance with regulations.

Estimated Repair Cost (2026 UK Prices)

The estimated repair cost for addressing a condensate fault on an Ideal Mexico HE is around £150 to £200. This includes clearing blockages or thawing frozen pipes, as well as any necessary labour charges.
