dI
Whirlpool Refrigerator
Severity: ModerateWhat Does This Error Mean?
The dI error means the ice maker in your Whirlpool refrigerator has detected a fault. The ice maker is not completing its harvest cycle as expected. The refrigerator and freezer continue to work normally — only ice production is affected.
Affected Models
- WRF535SWHZ
- WRS325SDHZ
- WRF767SDHZ
- WRX735SDHZ
- Most Whirlpool refrigerators with built-in ice makers
Common Causes
- The ice maker is turned off or the ice maker arm is in the raised (off) position
- The freezer temperature is too warm for ice production (should be 0°F / -18°C or colder)
- The water supply line to the ice maker is kinked, frozen, or the valve is closed
- The ice maker module itself has failed and needs replacement
- An ice jam in the ice bin or ejection mechanism is preventing the harvest cycle from completing
How to Fix It
-
Check that the ice maker is turned on and the ice maker arm is in the down (on) position.
The wire arm on traditional ice makers stops ice production when it is raised. Push it down to restart production.
-
Check the freezer temperature — it should be at 0°F (-18°C) or colder for proper ice production.
If the freezer is warmer than 10°F (-12°C), ice production will stop or be erratic.
-
Check the water supply line behind the refrigerator for kinks or a closed shut-off valve.
The shut-off valve is typically behind the refrigerator or under the sink. Make sure it is fully open.
-
Remove the ice bin and check for an ice jam in the bin or around the ejector arms.
Ice can clump together and physically block the next harvest cycle. Break up any clumps and reinstall the bin.
-
Press the ice maker's test button (if present) to run a manual harvest cycle.
On most Whirlpool ice makers, a small test button is on the side of the ice maker module. Hold it for 3 seconds to start a test cycle.
When to Call a Professional
If all basic checks pass but dI persists, the ice maker module itself may need replacement. Ice maker assemblies cost $50–$150 depending on the model. A technician can run a test cycle to confirm whether the ice maker or a related component (inlet valve, freezer thermistor) is at fault.
Frequently Asked Questions
How long does it take for ice production to resume after fixing the dI error?
Once the issue is resolved, allow 24 hours for the ice maker to produce a full bin of ice. The first few cycles may produce smaller or misshapen cubes as the system normalises. Discard the first batch if it looks cloudy or misshapen.
Can a dirty water filter cause the dI ice maker error?
Yes. A clogged water filter reduces water flow to the ice maker. If the ice maker does not receive enough water to fill the mold, it can trigger dI. Replace the water filter every 6 months or when the H2O indicator light comes on.
Is the dI error the same as the ice maker just being out of water?
Not exactly. If the ice maker runs out of water it will simply stop making ice without necessarily throwing an error. dI specifically means the ice maker module detected a problem completing its cycle. Both can be caused by water supply issues — checking the water supply is always a good first step.
