Make and model of gas boiler?
Potterton Promax Combi HE A Range..
It sounds like a water pressure error code, do you know to check & recharge it?
Have a look at the gauge, it should be on at least 1-2 bar
Yes its on 1-2 bar
Nope don't know how to check & recharge it
Only thing i have done is a reset on the boiler but still get the error code
Shows E1 -68
What does error code E168 mean?
If error code E168 is being displayed on your boiler it means that the boiler has detected a problem but can't work out exactly what it is. This could be because the boiler has been reset after developing a fault or because there has been an external issue, such as a fault with the electrical supply.
If the boiler has reset, it might have been displaying a different error code before resetting. Making a note of any error codes you see is extremely helpful to any installer trying to rectify the issue.
