Haier Dishwasher Error Code E3 — Water Level Incorrect
What this means
Error code E3 on Haier dishwashers indicates the water level is not correct — either too low or draining during the wash phase. The cycle stops to prevent pump damage from running dry. Common causes include a drain hose that is positioned too low (below 40 cm from the floor), allowing water to siphon out during operation, a leaking drain valve, a faulty water level sensor, or a problem with the inlet valve not maintaining water supply.
Alternate codes: Err3
Step-by-step fix
3 stepsCheck drain hose height
Ensure the drain hose loop is positioned at least 40 cm (16 inches) above the floor. If the hose goes straight down to the drain without a high loop, water will siphon out of the dishwasher during the wash cycle.
Most Haier dishwashers require either a high loop in the drain hose or an air gap fitting to prevent siphoning.
Verify water inlet supply
Ensure the water supply valve is fully open and the inlet hose is not kinked. Run a fill test — the dishwasher should fill to the correct level within about 2 minutes.
Low water pressure can cause the dishwasher to underfill, triggering E3 during the wash phase.
Test the water level sensor
Locate the water level sensor in the sump area. Check its wiring connections and test with a multimeter according to your model's specifications. A faulty sensor will misread the water level.
On some Haier models, the turbidity sensor doubles as a water level indicator — check your model's service manual.
When to call a professional
If the drain hose is correctly positioned and the inlet supply is good but E3 persists, the wash pump or control board may have an issue. A technician can run diagnostic tests.
