Turn off the water supply to the dishwasher. If it comes back, it needs a visit. ### Do I need to reset the flood switch after E4 on my ZLINE? No, ZLINE explains that the switch resets itself when the bottom of the unit dries out and whatever let the water in is fixed. Clear the water out of the base pan before you run it again. ### Can the wrong detergent cause E4 on a ZLINE? Yes, suds from the wrong detergent are on ZLINE's list, as is a machine that is not level. Shut off the water supply before checking either. --- **[Read on the site: ZLINE dishwasher showing E4 | DishwasherRepair.center](https://dishwasherrepair.center/error-codes/zline-e4/)** **[Book a visit with DishwasherRepair.center](https://dishwasherrepair.center/schedule/)**
