Fault codes on these boilers are shown as alternative flashing E or E1 and then two other numbers.

If the code has an A prefix this is a PCB programming code and should not be seen; this is usually due to a power supply fluctuation and resetting the boiler should clear it.

If the code is 0 or another number without a letter prefix, these are normal operating status codes. See user guide.
