Hi Jamie,
I've checked the user manual for the dishwasher but it does not mention just the eco light flashing. Have you tried to reset the dishwasher as mentioned in other posts regarding this unit.....instructions below. I hope this helps.
Turn off at the power button and leave for 10 seconds.
Turn on power button and press the program button 4 times
I found that you had to be very quick pressing the program button four times after powering up. You know you've hit it right when then two outer lights stay lit.
Then push the program button once.
Then power off (without closing the door).
Wait 15 seconds then power up and the reset should have taken place.
