An error code on these machines is either an F:XX number in a display or a combination of the spin speed led’s flashing.
Can’t say i’ve seen the combination you’ve mentioned here tbh .
You could try putting it into test mode briefly to see if that clears it.
Selector switch to 12 o’clock
turn selector switch to 6 o’clock
hold down spin speed button and turn selector 1 click clockwise – 7 o’clock and then release spin speed button.
You will then get 2 lights on RHS lit….this is appliance in test mode. Switch selector back to off and see if the lights you’re on about clear.
