Why is my Riello Array AR 2000 Boiler showing an IGNIT_ERROR?
An IGNIT_ERROR on your Riello Boiler can occur due to several reasons: * Incorrect gas supply pressure: Adjust the gas supply to the correct pressure. * Absence of spark: Check the ignition electrode position. * Incorrect combustion air pressure: Inspect the vent system and remove any obstructions. * Voltage to gas valve not being 120Vac: Replace the power control board.
What to do if my Riello Boiler displays a MAX_TEMP_ERROR?
If your Riello Boiler displays a MAX_TEMP_ERROR, it could be due to: * Faulty pump circulation: Change or restart the pump. * Closed valves on the hydraulic circuit: Open the valves. * Defective high limit switch: Replace the high limit switch.
How to fix a FLUE_PRESSURE_ERROR on a Riello Array AR 2000?
A FLUE_PRESSURE_ERROR on your Riello Boiler may be caused by: * An obstruction in the exhaust system: Remove any obstructions. * An obstruction in condensate discharge: Remove any obstruction and confirm that the condensate can flow freely.
Why does my Riello Boiler have TOO_MANY_FLAME_LOSS errors?
The TOO_MANY_FLAME_LOSS error on your Riello Boiler can be attributed to: * Damaged wires: Replace the damaged wires. * Improper combustion settings: Check for proper combustion settings. If the settings are correct, replace the spark/flame rod.
What causes a FAN_ERROR_NOT_RUNNING on a Riello Array AR 2000?
A FAN_ERROR_NOT_RUNNING on your Riello Boiler can stem from: * Absence of 120 VAC voltage: Replace the power control board. * Absence of PWM signal: Replace the power control board. * The fan itself may be faulty: Replace the fan.
What should I do if my Riello Array AR 2000 Boiler shows a GV_RELAY_ERROR?
If your Riello Boiler is displaying a GV_RELAY_ERROR: * Check the wires: If the wires are damaged, replace them. * If the wires are ok: Replace the gas valve or the power control board.
What does RETURN_OPEN mean on my Riello Array AR 2000 Boiler?
A RETURN_OPEN error on your Riello Boiler indicates: * Damaged wiring: Replace the wiring if damaged. * Defective temperature sensor: Verify the temperature sensor has the correct resistance values; if incorrect, replace the sensor.
What does SUPPLY_OPEN error mean on Riello Boiler?
A SUPPLY_OPEN error on your Riello Boiler means that: * The wiring is damaged: Replace it if damaged. * The temperature sensor is defective: Verify that the temperature sensor has the correct resistance values. If the values are incorrect, the sensor must be replaced.
What does DHW_OPEN error mean on Riello Array AR 2000 Boiler?
A DHW_OPEN error on your Riello Boiler indicates that: * The wiring is damaged: Replace it if damaged. * The temperature sensor is defective: Verify that the temperature sensor has the correct resistance values. If the values are incorrect, the sensor must be replaced.
What causes LWCO_2_ERROR in Riello Array AR 2000 Boiler?
The LWCO_2_ERROR in your Riello Boiler is caused by: * All valves are not open or the pump is not running: Verify water is in the boiler and verify a good connection between the control module and low water probe.
