Lochinvar FAQ

What does Lochinvar Error Code E004 mean?

E004 usually indicates ‘Flame Failure’ or an ignition issue — the boiler attempted to light but failed. This can be caused by lack of gas, a dirty spark igniter, or a flame sensor issue. A technician needs to verify gas pressure and clean the combustion assembly.

What does Lochinvar Error Code E010 mean?

E010 typically points to ‘Low Water Flow’ or a temperature rise issue — water isn’t moving through the boiler fast enough, causing it to overheat. This could be a failed pump, a closed valve somewhere in the system, or air trapped in the piping that needs to be purged.

How often should I service my Lochinvar boiler?

Lochinvar recommends annual maintenance — critical for high-efficiency condensing boilers. Service includes cleaning the condensate trap, inspecting the igniter and flame rod, checking combustion levels (CO/CO2), and flushing the heat exchanger if scale has accumulated.

Why is my Lochinvar boiler making a loud banging noise?

This is often ‘kettling’ — mineral deposits on the heat exchanger trap water that boils and creates steam bubbles. When the bubbles collapse, they bang. It means the system needs to be flushed and descaled immediately. Book a service call before it causes heat exchanger damage.
