Step-by-Step DIY Fix Guide
- SAFETY: Unplug the refrigerator before checking water line connections at the back of the unit.
- Check the water supply line at the back of the refrigerator — confirm it is connected and the shutoff valve is fully open.
- Check the ice maker arm (if your model has one) — it should be in the down (on) position. Raise it and lower it once to confirm it moves freely.
- Replace the water filter if it is overdue — Haier recommends replacement every 6 months.
- Plug in and power cycle the refrigerator, then wait 24 hours for the ice maker to resume production.
- If no ice is produced after 24 hours and the water supply is confirmed good, contact Haier service.
If it's still not filling correctly
- If normal household water flow looks good but the code returns, the inlet-valve or fill-sensing path becomes more likely.
- Er persists after checking water supply, arm position, and replacing the filter
- Water supply line is frozen solid — professional defrost and insulation inspection recommended
What This Error Means
Error Er on your Haier refrigerator means: The ice maker has encountered a fault and stopped producing ice. The error covers a range of conditions from a simple water supply issue to a failed ice maker module. The refrigerator's self-diagnostic system has flagged this condition.
The most frequent cause is water supply line not connected or the shutoff valve is not open — no water reaching the ice maker. Work through the checks below before calling a technician.
Some cases of Er can be resolved by the homeowner. The steps below cover all DIY checks — if they do not clear the code, a technician is needed.
Water supply issues account for the majority of ice maker faults. Confirm the shutoff valve is fully open and the water filter is within its service life before suspecting a hardware fault — these two checks resolve most Er codes without any tools or disassembly.
Most Likely Cause by Symptom
The Haier refrigerator may stop, pause, or refuse to complete the cycle normally.
Likely cause: Water supply line not connected or the shutoff valve is not open — no water reaching the ice maker
Check first: SAFETY: Unplug the refrigerator before checking water line connections at the back of the unit.
Performance may drop because airflow, filtering, or draining is restricted.
Likely cause: Frozen water supply line — water has frozen in the line running to the ice maker
Check first: Check the water supply line at the back of the refrigerator — confirm it is connected and the shutoff valve is fully open.
Common Causes
- Water supply line not connected or the shutoff valve is not open — no water reaching the ice maker
- Frozen water supply line — water has frozen in the line running to the ice maker
- Water filter clogged or overdue for replacement — restricts flow below the threshold needed for ice production
- Ice maker arm in the raised (off) position — the arm physically prevents ice production when raised
- Failed ice maker module — the ice maker itself has a hardware fault
What Not to Do
- Do not use a heat gun or open flame to thaw a frozen water supply line — use a hair dryer on low heat only, keeping it moving

When Not to Keep Troubleshooting
Er persists after checking water supply, arm position, and replacing the filter
- Water supply line is frozen solid — professional defrost and insulation inspection recommended
How to Prevent It Recurring
- Replace the water filter every 6 months — a partially clogged filter is the most common cause of reduced ice production before a full Er fault appears
