Some appliances malfunction can be displayed in hexadecimal or in binary code.
So your device is defective and shows you what's wrong. You have to count how many times flashes red light and how many times flashes green light. Red light shows the first error number and green light the second error number.
For example: you forgot to close the door and you started washing machine. After some time (timeout) will generate an alarm. Four times will flash red light and once the green light which means error code " E41 " or "Open door"
" E20 " means "No drain water"
" E10 " means "No fill up water"

Lift lid, stick screwdriver into slot where lid latch-pin inserts and see if it goes into the cycle. If so, try adjusting position of latch.

I had the same problem before, but removing the kink in drain hose does the trick. Maybe yours is more complicated but try it.

main wash and rinse lights both flashing together and machine stopped

If the START / PAUSE button lights up red, the washing machine detects a malfunction. Now you should count how many times the START / PAUSE button lights up red and tell to us what kind of malfunction is being done.

Try to rapid reading of alarm codes when the appliance is in normal operating mode (e.g. during the execution of the washing
programme):
Press and hold down START/PAUSE and the nearest option button for at least two seconds: the LEDs initially switch off, and then display the flashing sequence indicating the last alarm.

LED indicator START / PAUSE with red light = indicates the first digit of the alarm code (family)
• LED indicator START / PAUSE with green light = indicates the second digit of the alarm code (internal number of the family)

Hi-Temp Wash, Hi-Temp Rinse, or Sanitize options.
Some models have options that may require a water heating delay, such as Hi-Temp Wash, Hi-Temp Rinse, or Sanitize. Additional time may be required to heat the water to the proper temperature. The dishwasher will continue to circulate water during this heating delay but the timer will not advance until the proper temperature is reached

The red light tell you there is a fault. You have to read the fault code and it will give you a general idea of the problem - to do this you have to enter the service mode of operation - close the door and turn the dishwasher on.

That would be the balance switch, should be located rear right under the main board. over time the switch becomes jamed in the on position and the machine always thinks its off balance. $4 to $10 for a new one.
