What should I do if the ECO TUB CLEAN reminder keeps blinking?

The ECO TUB CLEAN indicator blinking after a wash cycle is not a system failure — it is simply a reminder to clean the tub. The reminder will remain active for 6 consecutive cycles until you run the ECO TUB CLEAN cycle. You can continue running normal cycles in the meantime, but it is recommended to run the cleaning cycle as soon as possible. (Page 38)
