Sub-Zero EC30 with Service flashing: the ice maker has shut itself down
On 600 and 700 Series units and IC-27 columns, code 30 (shown as EC30 or EC 30 with Service blinking) means the control counted too many long openings of the ice maker's water valve solenoid and stopped ice production.

What EC30
actually means.
On 600 and 700 Series units and IC-27 columns, code 30 (shown as EC30 or EC 30 with Service blinking) means the control counted too many long openings of the ice maker's water valve solenoid and stopped ice production. Sub-Zero's pages give a limit of 15 seconds per fill, and on the 600 Series five such fills in a row.

What to do when EC30 shows on the ice makerKind of codeWater 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 toIce 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 asNo 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.

Before you book,
in this order.
Each step comes from Sub-Zero's own guidance for EC30 on its ice makers. Follow it to the end: the last card says whether this is a visit.
Switch the ice maker off at its own control so it stops trying to fill.
Look in the ice maker for a cube wedged in the mold or ejector and clear it by hand, without tools.
Write down EC30 and the temperatures shown on the display, then book a visit if the code returns once the ice maker is back on.

Door ice maker
The ice maker that feeds the dispenser on the outside of a door: tucked into an insulated box in the left door of a French door model, or at the top of the freezer side of a side-by-side, with a chute and an auger carrying cubes to your glass.
Freezer ice maker
The ice maker that sits inside the freezer compartment itself, a tray that twists or a mold with a heater and an ejector, dropping cubes into a bin or drawer you open by hand, with no dispenser on the door.
Undercounter ice maker
A built-in residential ice maker that lives under a kitchen, bar or basement counter, making clear cubes or chewable nugget ice on its own cooling system, with a water line in and a gravity drain or a small drain pump out.

Still showing EC30?
Book with the code or the blink pattern written exactly as the ice maker shows it, the full model number, and whether there is any water on the floor — when there is a code, that is where the diagnosis starts.
