Cannot see any reference to a ‘door light’ in the info I have. The picture of the console is not brilliant but there is no mention of a door light. The digital display should show error messages if a fault is detected.
You could also try a reset, press & hold the Start/Reset button, display should show a line of dashes after two beeps.
Also, admittedly stating the obvious, check the door switch. 🙂
Your right it hasnt got a door light on this model only the lcd display, which has DOOR flashing on it, tryed reset option no joy also changed switch still the same. ❓
