Only green or red lights.
The start button flashed red 5 times, then went back to flashing green.
There is no display to show numbers. The button to the left of the start/pause button is the auto half load button (just to be clear) and I've pressed both at exactly the same time.
Oops - sorry. When I hold both buttons it's already flashing green and continues for another 2 flashes. That stops and the red flashes 5 times. Then it flashes green 4 times, then a wee break, before continuing to flash green. Checked a couple of times ;-)
