How to fix Ideal Logic Plus fault code E119

What does the Ideal Logic Plus E119 fault code mean?

The E119 fault code on the Ideal Logic Plus indicates low water pressure within the heating system. This can prevent the boiler from operating efficiently and may lead to further issues if not addressed promptly.

Common Causes

  • Low Water Pressure: This can occur due to leaks in the system or insufficient water in the boiler.
  • Pressure Relief Valve Issue: A faulty pressure relief valve may allow water to escape, leading to a drop in pressure.

Can I fix it myself? (DIY)

You can attempt to fix low water pressure by checking the pressure gauge on your boiler and using the filling loop to add water if necessary. However, if you suspect a leak or if the issue persists, it is crucial to call a Gas Safe Engineer for further inspection.

Estimated Repair Cost (2026 UK Prices)

The estimated repair cost for addressing low water pressure issues is around £150 to £250. This includes potential costs for refilling the system and checking for leaks, as well as any necessary repairs to the pressure relief valve.
