What EC30 means.

EC30 means the controller energized the ice-maker water valve and the valve did not de-energize within the expected window (typically 15 seconds on most Sub-Zero models). This is a flood-prevention code. If the valve is stuck open, water will keep pouring into the ice mold or the dispenser line until it overflows onto the floor. Once EC30 logs, the controller usually cuts ice production until the fault clears, which is why the ice bin will be empty for days alongside this code.

Most common causes.

  • Water inlet valve solenoid stuck open (failed open).

  • Ice maker mold thermostat jammed (calling for water that the valve cannot deliver).

  • Wire harness short between board and valve.

  • Control board valve-driver transistor failed.

Try this first: safe DIY troubleshooting.

  1. Shut off the water supply to the fridge at the saddle valve or shut-off behind the wall.

  2. Pull the ice bin and look for an overflow trail of ice down the back of the freezer.

  3. Leave water off until a technician can verify the inlet valve is closing.

  4. Do not keep running the unit with the water valve suspected open. Kitchen flood damage is the real risk here.

  • Ivan is the only repairman I would ever trust with our appliances! We have used him 3 times (for our dryer, our dishwasher, and most recently our oven). We called him when our oven unexpectedly stopped working and he got us scheduled right away and had it fixed immediately! He is prompt, incredibly knowledgable, very friendly, reasonably priced, and honest! Look no further if you have any appliance repair needs! Thank you again Ivan!! - Kate

  • Our ice maker in our GE Profile refrigerator stopped working. We contacted several vendors through Yelp and Esquire was quick to respond and were able to come out the next day. Our ice maker was back up and running right away! They were able to buy the proper part and install it all in one day. They were courteous and reasonably priced. I couldn't be more pleased with how it went.
