Fault codes related to this part (not the entire boiler). They usually have more possible causes: first rule out electrodes, wiring/connections, and gas supply. Verified with ≥3 sources.

CodeWhat does it mean?Cause and diagnosis (this part)
E01Safety lockout due to ignition failure.If the gas valve BI1013108 does not open/modulate, gas does not reach the burner and the boiler does not ionise; check the control voltage at the valve and pressure at the inlet/outlet ports during the ignition attempt.
E11Presence of parasitic flame.A gas valve that does not close tightly may allow gas to pass ('let-by') and maintain a flame signal with the burner off; check the valve's tightness (leak test/manometer) and rule out leakage to the burner after the closure command.
E20EVG lockout (gas valve control hardware fault).Fault in the solenoid/modulator of the BI1013108 valve or its operation; measure resistance of coils/modulator, presence of control signal/voltage, and continuity of wiring to the valve.
E22EVG lockout (flame after gas valve shut-off Ref. EVG).Defective closure of the gas valve allowing flame after the closure command; verify that the valve closes without residual flow (manometer on manifold/ionisation after closure) and replace if it allows gas to pass.
E23Gas valve modulator disconnected.Connector or modulating coil of the BI1013108 valve in open circuit/disconnected; check plug/modulator, continuity, and control signal (0–10 V or PWM depending on model).
E44Accumulated timeout anomaly of the gas valve without flame.The gas valve does not open/modulate in time (stuck or slow response) and retries accumulate without flame; check control voltage, opening times, and inlet pressure while it attempts to ignite.
How do I know if this gas valve is the one for my boiler?
Verify the reference BI1013108 printed and ensure your model is on the list of compatibles; also compare the connections with the original part. It is a Biasi / Biasi piece (Honeywell gas valve VK4105M).
What is it used for?
The gas valve regulates and modulates the gas flow to the burner.
Ignition faults, does not modulate, or smells of gas?
It could be the gas valve. IMPORTANT: gas handling ONLY by an authorised technician.
Which models is it suitable for?
Part shared by various models (see Compatibility). If your model does not appear, send us a photo of the marking and we will confirm it.
Installation and recommendations
Installation and pressure adjustment by authorised technician; mandatory leak check.
What does refurbished mean and what coverage does it have?
Part removed from a boiler out of service, inspected and tested. Includes 1-year warranty and 14-day return policy. Delivery within 2–4 working days in the EU.
