Remeha fault code E00.04
Fault code E00.04 on a Remeha boiler (including Gas) means: Return temperature sensor has been removed or measures a temperature below the range. 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.
