Beko WMB 81241LB Washing Machine

Beko WMB81241LB Main control module had blown components and burnt circuit board, DC control module did not look good. Fitted replacement main control module and DC control module. The machine would not start on any programme, the start indicator flashes continuously. the only thing that happens when the start/pause/cancel button is pressed is the degrees C indicator flashes off/on momentarily. holding the button in for 3-5 seconds changes the display to 0.00 from 0.39 with the start indicator flashing. during this time the door is locked but nothing else happens.
On entering Diagnostic/test Mode the display indicates error code E17 on releasing the start/pause/cancel button the display indicates all symbols, on pressing the start/pause/cancel button the display does not go into flashing mode but continues to be on steady, further pressing of the start/pause/cancel button does nothing at all. during this time the door is not locked.
I have checked the solenoid coils of the water valves and they both give a reading of approximately 3.5 K ohms.
I would appreciate any help you could give me to rectify this problem, i.e what to check for, or items to test/replace.
Kind Regards
