Valiant ecomax 208E showing Fault code 05 and 40
Plumberpro :

Hi , does the display have an f next to those numbers?

Customer: Yes
Plumberpro :

Hi , can you confirm the model of the boiler , is it a 208e or 282,2e?

Customer: Valiant ECOmax 828 E
Plumberpro :

Hi those diagnostic codes refer to the flow temperature. A fault with the temperature thermistor could cause an overheat situation, causing lock out , then having to reset . change the temperature stats. They are relatively cheap an fairly easy to fit


many thanks

Plumberpro :

Your welcome . on the flow and return pipes , just below the heat exchanger.

Customer: Many thanks
