If you’re facing an error code or your Ideal boiler isn’t functioning as it should, a reset may help. Here’s a quick guide to safely resetting your Ideal boiler in 2025.
Step 1: Check the Display
First, look for any error codes on the boiler’s display. Common codes include “L2,” which usually indicates a flame failure. These codes can guide you on whether a reset is appropriate or if further inspection is needed.
Step 2: Locate the Reset Button
On most Ideal boiler models, the reset button is situated on the front panel, usually near the display. It may be marked with the word “RESET” or have a small icon that resembles a circular arrow.

Step 3: Press and Hold the Reset Button
Press and hold the reset button for about 3-5 seconds until the boiler restarts. Some Ideal models may emit a small click or show a change on the display, indicating the reset process has started. If the boiler restarts and operates normally, your reset is complete.
Step 4: Observe the Boiler
After resetting, let the boiler run and monitor for any unusual noises or error messages. If the problem persists or the boiler doesn’t ignite, it may indicate an issue requiring a professional inspection.
Troubleshooting Tips
- Repeat Only If Necessary: Avoid frequent resets, as it may signal a more serious issue with the boiler.
- Refer to the Manual: Always consult the user manual specific to your Ideal boiler model for reset instructions.
