If your Intergas Boiler displays a sensor fault after a self-check, replace S1 and/or S2.
Why is there no heating (CH) in my Intergas Boiler?
If your Intergas Boiler isn't providing heat, consider the following troubleshooting steps: * Replace the thermostat if it's faulty. * Check the wiring against the diagram. * Check the connector X4 if there's no current (24 V). * Replace the faulty manager. * Check the power supply at connector X2. * Replace the faulty pump if it's not running. * Replace sensor S1 or S2 if the burner isn't firing on CH. See fault code. * Refer to the 'burner does not ignite' section if the burner isn't igniting.
Why does my Intergas Combi Compact HRE 36/30 Boiler burner ignite noisily?
If your Intergas Boiler's burner ignites noisily, it could be due to several reasons: * The gas supply pressure might be too high. The house pressure switch may be faulty; contact the gas company. * The ignition electrode gap may be incorrect; check the ignition electrode gap. * The gas/air adjustment may not be correctly set; check the setting (refer to gas/air adjustment guidelines). * There might be a weak spark; the spark gap should be approximately 4.5 mm.
Why is my Intergas Combi Compact HRE 36/30 not producing hot water (DHW)?
If your Intergas Boiler is not providing hot water, consider the following: * Replace the flow switch if the DHW flow is less than 2.0 l/min. * Check the wiring according to the diagram if there's no current at the flow switch (5V DC). * Replace S3 if the burner isn't firing on DHW. * Refer to the 'burner does not ignite' section if the burner isn't igniting.
Why is the burner resonating in my Intergas Boiler?
If your Intergas Boiler's burner is resonating, consider these potential causes: * The gas supply pressure may be too low. The house pressure switch may be faulty; contact the gas company. * There might be recirculation of combustion gasses; check the gas flue and the air supply. * The gas/air adjustment might not be correctly set; check the setting (refer to gas/air adjustment guidelines).
Why does the hot water from my Intergas Combi Compact HRE 36/30 not reach temperature?
If your Intergas Boiler's hot water isn't reaching the desired temperature, consider the following: * Adjust the inlet assembly if the DHW flow is too high. * Set the hot water circuit depending on the desired temperature, if the temperature setting for the water circuit is too low. * Descale or flush the exchanger DHW side if there's no heat transfer due to lime scale or fouling in the heat exchanger DHW side.
Why is there no flame signal in my Intergas Combi Compact HRE 36/30?
If your Intergas Boiler is not showing a flame signal, make sure the gas tap is open, check for correct ignition gap, ensure proper gas supply pressure, and verify the gas valve or ignition unit is powered.
What to do if the temperature is too high in Intergas Combi Compact HRE 36/30 Boiler?
If your Intergas Boiler is overheating, possible solutions include: * Removing air from the installation. * Ensuring the pump is running. * Verifying sufficient flow in the installation, checking that radiators are open, and ensuring the pump setting isn't too low. * Checking if the flow switch is sticking.
How to restore power if it's reduced in Intergas Boiler?
If your Intergas Boiler's power is reduced, check the appliance and flue system for fouling and clean them.
What to do if my Intergas Combi Compact HRE 36/30 displays sensor fault S2?
If your Intergas Boiler displays a sensor fault S2, check the wiring for any breaks and replace S2 if necessary.
