Why Riello Appliances Need Specialist Repair
Riello appliances incorporate advanced proprietary systems that require certified engineers with brand-specific training to diagnose and repair correctly.
Riello appliances use integrated electronic diagnostics. Our engineers connect directly to Riello control boards using brand-specific tools to read fault codes and pinpoint issues accurately.
Every repair uses genuine Riello spare parts sourced directly from authorised distributors. Original components ensure compatibility, performance and longevity — backed by a manufacturer warranty.
Riello appliances must meet strict UK safety regulations. Our certified engineers follow Riello service procedures and test every repair to BS EN standards before sign-off.
Many Riello appliances feature Wi-Fi connectivity and smart home integration. Our engineers can diagnose firmware issues, reset connectivity modules and restore remote control functionality.
Common Riello Error Codes
What does error E077 mean on a Riello Family KIS boiler?
Error E077 on a Riello Family KIS boiler indicates a flow/return sensor differential alarm, which may signal a circulation or sensor fault. Do not attempt to repair gas appliances yourself. Switch off the boiler immediately. If you smell gas, do not operate any switches, ventilate the area if safe, leave the property, and call the Gas Emergency Service from outside. Contact a Gas Safe registered engineer to diagnose the fault.
What does error E020 mean on a Riello Family KIS boiler?
Error E020 on a Riello Family KIS boiler indicates low water pressure requiring the system to be charged. Do not attempt to repair gas appliances yourself. Switch off the boiler first, then check the pressure gauge. If pressure is below 1 bar, you may repressurise to between 1 and 1.5 bar using the filling loop, then press OK to charge. If pressure drops repeatedly, contact a Gas Safe registered engineer to check for leaks.
What does error E010 mean on a Riello Family KIS boiler?
Error E010 on a Riello Family KIS boiler indicates a flame lockout or ACF electronic fault. Do not attempt to repair gas appliances yourself. If you smell gas, do not operate any switches, ventilate the area if safe, leave the property, and call the Gas Emergency Service from outside. Check externally that the gas supply valve is open. You may attempt a reset by switching the boiler off and on again. If the fault persists, contact a Gas Safe registered engineer.
What does error A02 mean on a Riello Start Condens boiler?
Error A02 on a Riello Start Condens boiler indicates a limit thermostat alarm causing a definitive lockout. The boiler has exceeded safe temperature limits. Do not attempt to repair gas appliances yourself. Switch off the boiler and allow it to cool completely. If you smell gas, do not operate any switches, ventilate the area if safe, leave the property, and call the Gas Emergency Service from outside. Contact a Gas Safe registered engineer to check system circulation and heat exchanger condition.
What does error E118 mean on a Riello ALU PRO boiler?
Error E118 on a Riello ALU PRO boiler indicates a pump fault - the primary pump is on but the flow switch input is open. This suggests the pump is running but water is not circulating properly. Do not attempt to repair gas appliances yourself. Switch off the boiler. If you smell gas, do not operate any switches, ventilate the area if safe, leave the property, and call the Gas Emergency Service from outside. Contact a Gas Safe registered engineer to check the pump, flow switch, and system for blockages.
Frequently Asked Questions
How often should the blast tube be cleaned on a Riello burner?
The blast tube should be regularly cleaned using a stiff brush, compressed air, or a neutral cleaner to remove debris. This is typically done every 1,000-2,000 operating hours or during annual servicing.
How do I know if my Riello burner's photocell needs attention?
The photocell detects the presence of flame. Signs of photocell problems include random lockouts, lockouts shortly after ignition, or the burner failing to detect a visible flame. The photocell should be cleaned during annual servicing by an OFTEC registered heating technician. Do not attempt to access internal components yourself.
How does boiler frost protection work on Riello condensing boilers?
Riello condensing boilers have built-in frost protection that activates when the water temperature drops below approximately 5°C. The boiler automatically heats the water to around 10°C, then switches off. This cycle repeats as needed to prevent freezing. Note that this only protects the boiler itself - external pipework still requires separate insulation.
What are the electrode gap settings for a Riello oil burner?
For Riello 40 series oil burners (F3, BF3, F5, BF5, R35), the electrodes should be positioned 5mm above the centre of the nozzle, 2-2.5mm in front of the nozzle, with a 4mm gap (+/- 0.3mm) between electrode tips.
What should I do if my Riello boiler shows a low pressure warning?
If the pressure gauge reads below 1 bar, you need to repressurise the system. Locate the filling loop (a flexible braided hose with valves), open both valves until the pressure gauge reaches 1-1.5 bar, then close both valves. If the pressure drops repeatedly, this may indicate a leak in the system - contact a Gas Safe registered engineer to investigate and repair the fault.
