E060 Boiler Fault Code: What It Means on Every Brand

The E060 fault code appears on 2 brands — Navien and Vokera — and it does not mean the same thing on each. The same two or three characters can signal a pressure problem on one boiler and an ignition fault on another, so identify your brand first and use the table below to jump to the right page.

E060 brand by brand

Navien E060

The E060 fault code on Navien boilers and water heaters indicates that the unit has detected an abnormality with the dual venturi system. The dual venturi is a precision component that controls the mixture of air and gas entering the burner — getting this ratio right is essential for safe, efficient combustion. When the boiler runs its self-check routine and the dual venturi actuator motors cannot open and close the valves correctly, or when the wiring to the venturi is disconnected or damaged, the E060 code is triggered. The boiler enters lock-out mode, begins a continuous post-purge cycle, and activates the dual venturi circulation pump. On some Navien models, E060 can also relate to a fan motor fault where the fan fails to reach the required speed — always cross-reference with your specific model's service documentation. Either way, this is a lock-out fault and the boiler will not fire until the underlying issue is resolved.

Vokera E060

The E060 code appears on Vokera boilers when the control board cannot obtain a reliable temperature reading from the domestic hot water (DHW) probe — also known as a thermistor. This small sensor continuously monitors the temperature of your hot water supply by measuring changes in its electrical resistance; as water heats up, resistance drops, and those readings are fed back to the PCB to regulate output. When the signal falls outside expected parameters — due to a failing sensor, damaged wiring, or a PCB issue — the boiler flags E060 and may display fluctuating hot water temperatures or refuse to produce hot water altogether.

Frequently asked questions

Is the E060 fault code the same on every boiler?

No. E060 means different things on different brands — see the table above. Always identify your boiler's brand (it is printed on the front casing) before acting on any advice about the code.

Can I fix a E060 fault myself?

Not usually. On every brand listed, E060 points to a fault that needs a suitably registered engineer to diagnose and repair. A single reset to rule out a transient glitch is reasonable; repeated resets are not.

Who should I call about a E060 fault?

For gas boilers, a Gas Safe registered engineer — it is a legal requirement for any work on the appliance. If you smell gas at any point, leave the property and call the National Gas Emergency line on 0800 111 999.

General guidance only — not a substitute for professional advice, and not certified by a registered engineer. Any work on a gas appliance must be carried out by a Gas Safe registered engineer. If you smell gas, call 0800 111 999.
