Sorry for the delay in getting to your question.
The rinses light flashing indicates a fault in the motor circuit.
This can be the motor, the wiring or the control board.
Check the motor carbon brushes, if they have worn out, replace them and try the machine again.
If still faulty you may have to replace both the motor and the control board to get the machine working again.
Check the motor first.
See what you find.
Hope this is of some help
Let me know how it goes or if you need more help
