How to Reset a Vokera Boiler: Step-by-Step Guide
A working boiler helps keep your home warm and provides hot water when you need it. If you have a Vokera boiler and it stops working, a simple reset may help clear a temporary fault. However, resetting should only be done after checking basic issues such as pressure, power supply, and fault lights. If the fault keeps coming back, you should contact a Gas Safe registered engineer.
When Should You Reset a Vokera Boiler?
You may need to reset your Vokera boiler when it enters lockout mode or shows a warning light. A reset can help if the problem is temporary, such as a short power interruption or low pressure that has already been corrected.
You should consider resetting your boiler when:
- The boiler shows a red warning light.
- The display shows a fault code or error message.
- The boiler has stopped providing heating or hot water.
- The boiler has gone into lockout mode.
- You recently fixed a simple issue, such as low pressure.
- The boiler failed to ignite after a temporary gas or power interruption.
However, you should not keep resetting the boiler again and again. If the same fault returns, the boiler may have a deeper issue that needs proper inspection.
Where Is the Reset Button on a Vokera Boiler?
The reset button is usually located on the front control panel of the boiler. Depending on the Vokera model, it may appear as:
- A button labelled Reset
- A button with a flame symbol
- A control knob that turns to a reset position
- A small button near the display or indicator lights
The exact location can vary between Vokera models such as Compact, Linea, Vision, Mynute, Unica, and Easi-Heat boilers. Therefore, always check your boiler user manual before carrying out a reset.
How to Reset a Vokera Boiler – Step-by-Step
Time needed: 5 minutes
Here is a simple way to reset most Vokera boilers:
- Check the Boiler Display
First, look at the display screen or indicator lights. If there is a fault code, write it down before resetting the boiler. This helps you or an engineer understand the problem if the fault returns.
- Check the Boiler Pressure
Next, check the pressure gauge. Most boilers work best when the pressure is around 1.0 to 1.5 bar when the system is cold. If the pressure is too low, the boiler may not work properly.
- Locate the Reset Button
Find the reset button on the front control panel. It may say Reset or show a small flame symbol. Do not remove the boiler cover or touch any internal parts.
- Press and Hold the Reset Button
Press and hold the reset button for a few seconds, depending on your model instructions. Some Vokera boilers may need the control knob turned to the reset position instead.
- Wait for the Boiler to Restart
After resetting, wait a few minutes while the boiler restarts. The fan, pump, and ignition sequence may begin again if the boiler is working correctly.
- Test Heating and Hot Water
Finally, turn on a hot water tap or increase your room thermostat. If the boiler fires up and works normally, the reset has cleared the temporary issue.
Understanding Red and Green Light Indicators
Many Vokera boilers use lights to show the boiler’s current condition. These lights can help you understand whether the boiler is working normally or needs attention.
Red Light
A red light usually means the boiler has detected a fault. This may happen because of ignition failure, low pressure, overheating, or another system problem. In many cases, the boiler will enter lockout mode to protect itself.
Green Light
A green light usually means the boiler is operating normally. It may show that the boiler has power, is ready to work, or is currently providing heating or hot water.
If the red light returns after resetting, do not keep pressing the reset button. Instead, check the manual or contact a Gas Safe registered engineer.
Troubleshooting Tips Before and After Reset
Before or after resetting your Vokera boiler, check these simple points:
- Make sure the boiler has power.
- Check that the gas supply is turned on.
- Look at the pressure gauge.
- Check whether the thermostat is set high enough.
- Make sure the heating timer or programmer is switched on.
- Inspect the condensate pipe during cold weather.
- Check for visible leaks around the boiler or pipework.
- Listen for unusual noises after the boiler restarts.
Do not remove the boiler casing or try to repair internal parts yourself. Boiler repairs should always be handled by a Gas Safe registered engineer.
When to Call a Gas Safe Registered Engineer
A reset can fix small temporary faults, but it will not repair a serious boiler problem. You should call a Gas Safe registered engineer if:
- The boiler keeps locking out.
- The red light keeps coming back.
- The same fault code appears again.
- The boiler makes unusual noises.
- There is no heating or hot water after reset.
- The pressure keeps dropping.
- You notice leaks around the boiler.
- You smell gas or suspect a gas leak.
If you smell gas, turn off the gas supply if safe to do so, open windows, avoid using electrical switches, and contact the gas emergency service immediately.
Final Thoughts
Resetting a Vokera boiler is a simple step that may help clear temporary faults and restore heating or hot water. First, check the display, pressure, lights, and basic controls. Then, follow your model’s reset instructions carefully. However, if the boiler keeps showing the same fault or locks out again, stop resetting it and contact a Gas Safe registered engineer for safe diagnosis and repair.
Frequently Asked Questions
You can usually reset a Vokera boiler by pressing and holding the reset button on the front control panel. On some models, you may need to turn a control knob to the reset position instead.
The reason your Vokera boiler is not firing up may be due to various factors such as a lack of power, low pressure, or issues with the thermostat. Check these elements before seeking professional assistance if the problem persists.
To reset a hot water boiler, locate the reset button on the control panel. Press and hold the button for 10 seconds, then wait a minute to see if the system resumes normal operation. If the error persists, repeat the process.
A red light usually means the boiler has detected a fault and may have entered lockout mode. You can try one reset, but repeated red lights should be checked by a Gas Safe engineer.
Yes, if the boiler does not restart after a safe reset, call a Gas Safe registered engineer. The fault may involve ignition, sensors, gas supply, fan, pump, or another internal component.
