Sub-Zero ice maker display · also shown as 30, EC 30 What to do when EC30 shows on the ice maker ### Kind of code Water supply and fill The ice maker asked for water and got too little, too slowly or none at all, or water kept arriving after the fill should have ended. A closed shutoff, a kinked line, a clogged filter and low house pressure are ruled out before the water inlet valve is replaced or the fill tube is thawed. If water is on the floor, close the supply valve before reading anything on the display. ### Usually leads to Ice maker water inlet valve repair The electric valve that lets water into the ice maker, tested and replaced when it will not open, opens only partway, or keeps dripping after it should have closed. ### Shows up as No Ice Coming From the Ice Maker The mold sits empty or holds one frozen batch that never drops, the bin stays bare for days, and the dispenser gives water as usual: an ice maker not making ice while the rest of the appliance carries on normally. ### Make Sub-Zero Sub-Zero ice maker service, for ice makers in built-in units and those under the counter. ### Source Sub-Zero answer: 600 or 700 Series EC 30 and Service flashing 600 Series, 700 Series and IC-27 integrated columns with an automatic ice maker.

Switch the ice maker off at its own control so it stops trying to fill. If it comes back, it needs a visit. ### Why did my Sub-Zero ice maker stop after EC30 appeared? The control shuts the ice maker down on purpose when its water valve has been energized too long, too many times. That protects the freezer from an overfilled mold and spilled water. A stuck cube in the mold is the first thing to look for. ### Can a jammed cube really cause EC30 on a Sub-Zero 700 Series? Yes. Sub-Zero's own first step for code 30 on the 700 Series is to check the ice maker for jammed cubes and clear them. A cube that holds the mold or ejector out of position can keep the fill cycle from finishing normally. ### Should I keep using the freezer while EC30 is showing? Yes, the code concerns ice making only, so frozen food can stay where it is. Keep the ice maker off until a technician has looked at the valve, the fill tube and the ice maker module. --- **[Read on the site: Sub-Zero EC30 with Service flashing: the ice maker has shut itself down](https://icemakerrepair.center/error-codes/sub-zero-ec30/)** **[Book a visit with IceMakerRepair.center](https://icemakerrepair.center/schedule/)**
