Riello Appliance Repair in Grange

What does error A07 mean on a Riello Start Condens boiler?

Error A07 on a Riello Start Condens boiler indicates an NTC heating outlet probe fault or overtemperature condition. This starts as a temporary fault but becomes definitive if it recurs. Do not attempt to repair gas appliances yourself. Switch off the boiler and allow it to cool. 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 temperature sensors and system circulation.

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.

What does error E133 mean on a Riello ALU PRO boiler?

Error E133 on a Riello ALU PRO boiler means no flame was detected during the ignition sequence. 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 and other gas appliances work. Contact a Gas Safe registered engineer for diagnosis.

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 E110 mean on a Riello ALU PRO boiler?

Error E110 on a Riello ALU PRO boiler indicates the safety temperature has been exceeded and the safety thermostat has intervened. Do not attempt to repair gas appliances yourself. Switch off the boiler and allow it to cool completely. If this fault recurs, contact a Gas Safe registered engineer to check system circulation and pump operation.

How often should the oil filter be replaced on a Riello system?

The external oil filter should be replaced at least once a year. The filter container should be thoroughly cleaned before installing the new filter.

What causes a Riello oil burner to fail to ignite?

Common causes include air in the fuel line after running out of oil, a clogged nozzle, dirty or misaligned electrodes, a weak ignition transformer, or clogged fuel filters. Nozzles should never be cleaned - they must be replaced annually. Contact an OFTEC registered heating technician if the burner fails to ignite after two or three reset attempts.

Why does my Riello burner take approximately 70 seconds to establish a flame?

This is normal operation. The integrated control system is self-checking, and the cycle from start-up to flame establishment takes approximately 70 seconds. During this time, the control box performs safety checks before allowing ignition. If the burner fails to establish a flame within the safety time, it will lock out.

What does the anti-blocking function do on a Riello boiler?

Riello boilers feature an anti-blocking system that automatically initiates a short operating cycle every 24 hours of standby. This prevents the pump and other moving parts from seizing due to prolonged inactivity, particularly during summer months when heating is not in use.

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.
