What it means
The Logic Combi2 shows it as L 0C. The Logic Max Combi and Vogue Max spell it out as Too Many Restarts.
What to check, in order
- Turn the power off and on at the fused spur
Ideal says switching the power off and on again at the fused spur switch clears it.
- Note the code that comes back
When the boiler restarts, the code it shows next is the real fault. Look that one up.
- Don't keep pressing reset
Five resets in 15 minutes brings LC straight back.
When to call a Gas Safe engineer
If the original fault keeps returning, contact Ideal or a Gas Safe registered engineer with that code.
