Ice Maker Not Making Ice? Water Pressure, Filters and Hard Water
Updated
Short answer
- Water on and line not kinked; do not push the fridge so far back it pinches the line (Whirlpool).
- Freezer cold enough; too warm means slow production, small cubes or none (Whirlpool).
- Ice maker switched on (wire arm down or button on).
- Filter current; an old one restricts flow.
- Pressure: Whirlpool says below 20 psi the valve cannot feed the ice maker; at 20 psi or more, the valve may need replacing. Freestanding units want 30 to 120 psi, and reverse osmosis can drop pressure too low (Whirlpool).
Hard water
GE says minerals build up on freestanding ice makers' freezing plates, and they may need cleaning as often as every six months depending on hardness (GE). Angi notes inlet valves are prone to mineral buildup (Angi).
Repair costs: inlet valve $90 to $225, control board $150 to $300, motor or gear $120 to $400 (Angi). See ice maker repair.
Quick answers
What water pressure does an ice maker need?
Whirlpool says at least 20 psi for a refrigerator's inlet valve, and 30 to 120 psi for its freestanding ice makers.
Can hard water stop an ice maker?
Yes. GE says mineral buildup on the freezing plate can stop ice from releasing, and Angi notes inlet valves are prone to mineral buildup.
