Frequently Asked Questions - WH100EW1 VOX
How do I reset the boiler after a fault?
Press and hold the reset button (usually marked with a flame icon) for 3 seconds. If the fault persists, check the error code and consult the manual.
What does the red light mean on the boiler?
A steady red light typically indicates a lockout or fault condition. Refer to your manual for specific error codes. A flashing red light may indicate ignition failure.
How often should I service my VOX boiler?
An annual service by a qualified Gas Safe registered engineer is recommended to maintain efficiency and safety.
Why is my boiler losing pressure?
Common causes include a leak in the system or a faulty pressure relief valve. Check for visible leaks and repressurize to 1-1.5 bar if needed. If pressure drops repeatedly, call a professional.
Can I use the boiler without the thermostat?
Yes, the boiler can operate without a thermostat, but it will run continuously until manually turned off. For energy efficiency, a thermostat is strongly recommended.
What type of gas does the WH100EW1 use?
It is designed for natural gas (G20/G25). For LPG use, a conversion kit is required; consult your installer.
How do I clean the boiler filters?
Turn off the power and gas supply, remove the front cover, locate the inlet filter (usually near the water inlet), clean it with a brush or water, and reinstall. For detailed steps, refer to the manual.
Why is there no hot water?
Check if the boiler is on and the thermostat is set above room temperature. Ensure gas supply is active. If the heating works but no hot water, the diverter valve may be faulty.
What does error code E01 mean?
E01 typically indicates ignition failure. Check that gas is supplied and the igniter is working. Reset the boiler; if it persists, call a technician.
Is the boiler compatible with smart thermostats?
Yes, it is compatible with most 24V on/off or OpenTherm smart thermostats. Consult the manual for wiring details.
