Common Ideal Issues and What They Mean
We frequently encounter L2 ignition lockouts, F1 low pressure warnings, and diverter valve wear on higher-mileage Ideal Logic units. An L2 lockout might be a relatively simple igniter or flame sensor replacement, but repeated occurrences can point to deeper combustion issues. F1 low pressure is often a symptom, not the cause, indicating a system leak or expansion vessel fault. Diverter valve wear, particularly on older Logic+ and Isar/Icos models, can manifest as inconsistent hot water or heating, and while repairable, it's a key indicator of age.
- L2 Ignition Lockouts: Can be minor or hint at bigger problems.
- F1 Low Pressure: Often a symptom of system leaks.
- Diverter Valve Wear: Common on older models, affects hot water consistency.
