I have no idea what that error code represents but I can only suggest you check all the usual (motor,heater,base flood switch etc) to see if anything shows up?
You will need the relevant spin speed led that’s flashing too.
I.e if it’s the middle spin speed LED and the bottom 2 progress LED’s (spin and end ?) then that’ll be F:43 – motor fault .
The combination of LED’s is important so if you post the correct one’s here , i’ll try and point you in the right direction.
P.s If it is F:43 motor fault , you’ll need to also reset the machine via the test program after sorting the problem
