Elco fault code 13
Fault code 13 on an Elco boiler (including Rendamax) means: Faulty flue gas temperature sensor/locking input was interrupted. Reset the appliance once. If the code comes back, a part is usually faulty, often a temperature sensor. 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.
