What Causes Error 10
Error 10 on Immergas boilers often points to electrical problems. Loose wires or a faulty power supply can stop the boiler from working right. Small issues like these can cause big trouble.
Sensor failures are another common cause. Sensors check temperature and pressure inside the boiler. If a sensor breaks or gives wrong signals, the system will show Error 10. This helps protect the boiler from damage.
Both electrical issues and sensor problems need quick attention. Fixing these errors usually requires checking wires and testing sensors. Simple steps that keep your boiler safe and running well.

Safety Precautions Before Fixing
Always turn off the power before starting any repair. This stops electric shock risks. Use the main switch or unplug the unit. Never work on the system while it is live.
Wear protective gear like gloves and safety glasses. It protects you from sharp parts and hot surfaces. Dress in clothes that cover your arms and legs. Safety first, always.
Step-by-step Quick Fixes
Resetting the boiler can often clear error 10. Turn off the boiler and wait for 5 minutes. Then switch it back on. This simple step may solve the problem quickly.
Checking water pressure is important. The pressure gauge should read between 1 and 1.5 bar. If the pressure is too low, add water using the filling loop. Too high? Let some water out until it is right.
Inspecting wiring connections helps find loose or damaged wires. Turn off the power before touching anything. Tighten any loose wires and check for visible damage. Safe and secure wiring keeps the boiler running well.
When To Call A Professional
Signs of serious problems include persistent error codes and unusual noises. The boiler may stop heating water or show a flashing error 10. Strange smells or leaks also signal trouble. These signs mean the boiler needs expert care.
Avoiding further damage means not trying to fix complex issues yourself. Turn off the boiler to prevent more harm. Keep the area clear and do not use the appliance until a professional checks it. Quick action can save money and keep your home safe.
Preventing Error 10 In Future
Regular system checks help keep your boiler running smoothly. Check the pressure gauge weekly. It should stay between 1 and 2 bars. Look for any leaks or strange noises. Clean dust and dirt from the boiler’s surface to avoid blockages. Test the thermostat to ensure it works properly. Use a soft cloth to wipe it gently.
Check the pilot light color. It should be blue, not yellow or orange. Yellow flames may signal a problem. Keep vents and flues clear to allow good airflow. Blocked vents can cause Error 10. Schedule annual professional servicing to catch hidden issues early.
