What This Code Means

F20 appears when the control system determines that water flow into the appliance has not reached the expected level within a programmed time window. The washer monitors both fill duration and internal water level signals. If the system does not detect the required increase in water level, it interrupts the cycle. This code reflects a fill-condition monitoring response rather than a confirmed mechanical defect. It does not automatically indicate that a component has permanently failed.

Where Users Usually See This Code

At the beginning of a wash cycle
During the initial fill stage
On the appliance control display

Why This Code Appears

Fill time exceeds programmed threshold

Intake monitoring timeout triggered

What Typically Happens Next

The cycle pauses

The machine may attempt a brief retry before stopping

What This Code Is Not

It is not a drain system fault
It is not a motor malfunction
It is not a heating issue

Troubleshooting Checklist

□ Confirm that the water supply is active
□ Allow the appliance to reset

Notes And Edge Cases
