Intergas fault code 5
Fault code 5 on an Intergas boiler (including Kompakt Solo) means: Gas inlet pressure too low or drops out. Lower than 20 mbar. Reset the appliance once. If the code comes back, a part is usually faulty. You can check the water pressure and settings yourself; leave work on gas-carrying parts to a certified gas engineer.
After a safety alert (gas, flue gas, combustion), reset no more than once and call in a certified gas engineer. If you smell gas, call your national gas emergency number or 112 immediately.
