EC 30: Ice Maker Fill Valve Held Open Too Long

EC 30 is what a later 600 Series control stores once the ice maker's water valve has stayed open longer than fifteen seconds on five separate fills. On the panel it shows as ICE and SERVICE flashing together, and the bin stops filling. Sub-Zero Repair Redmond checks the ice maker, the supply and the valve in turn; call (425) 905-2822.

EC 30 at a glance — Sub-Zero Repair Redmond, (425) 905-2822
Means Five times, the control kept the ice maker's water valve powered for more than fifteen seconds, and it logged that count as a stored fault.
Check first
  • With the ICE key switched off, look into the ice maker for a cube wedged in it and lift it out.
  • The shut-off valve on the water line turned fully open, not left partly closed after other plumbing work.
  • Whether ICE and SERVICE are flashing together on the display.
Needs a technician
  • Ice maker level, and the fill cup moved if it sits in the path of the ice.
  • Supply pressure at the unit, which has to hold steady between 20 and 100 psi.
  • The water valve: it must open when 115 V reaches it and shut completely when the power is taken away.
  • The white-wire circuit from the valve solenoid back to the control board.

Where the water comes in

The ice maker sits inside the freezer section; its water arrives on copper rising through the floor near the back wall, or through the wall low down. Nothing in this code points at the panels or the cabinetry.

What keeps the valve open

Sub-Zero’s service manual tests the ice maker before the water or the valve: a jammed cube, an ice maker out of level, a fill cup in the path of the ice. Supply pressure comes next, then the valve and its wiring.

Early and later controls

A 600 Series built before serial number 1810000 flashes the same ICE and SERVICE pair but stores no code. On the later control EC 30 waits in Diagnostic Mode.

Series, readout,
then a price

Give us the model off the tag and whatever the display is showing. When the fix is a clean condenser or a reset you can do yourself, you will hear that on the phone. When it needs a technician, the visit is $89 and it comes off the repair bill; the price for the work is in writing before anything is opened.
