Thanks for the response but this model only has 3 lights that run vertically on right hand side of fascia.
wash,dry and end! So it’s the top (wash) and bottom (end) lights that are lit along with the adjacent start button.
At the same time the salt, rinse aid and on/off lights which are situated on the left hand side of the fascia are flashing.
Ignore the on/off, salt and rinse aid lights, the start button is one of the four lights used for error codes plus the other three, the lights you say are flashing are 1+3+4. Error E11.
