Hi , does the display have an f next to those numbers?
Hi , can you confirm the model of the boiler , is it a 208e or 282,2e?
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
where do the temp stats go
Your welcome . on the flow and return pipes , just below the heat exchanger.
