All that happens is the top panel lights keep flashing……
I’ve tried all sorts of button combos but nothing seems to work
it does however say on L/H/S it shows either LL or 0 R/H/S shows either L or 9
Can’t find any reference to those codes only one referring to LL &. L which is display locked – press and hold alarm button to release
if it’s new then book a service call with Smeg
