Quick Assessment
Answer to continue safely
Is it safe to keep using?
Yes. No water entering means no immediate hazard, but the dishwasher cannot clean dishes until the water supply issue is resolved.
Can I reset the code?
Yes. Restoring proper water flow and running a new cycle will clear the error. No power reset needed.
When to stop immediately?
Stop if you notice: Water supply is confirmed on but unit still will not fill, Inlet valve buzzes but no water enters.
Symptoms You May Notice
Dishwasher stops early without washing
The cycle begins but halts before any spray arm activity — dishes remain dry.
No water sound during fill phase
You do not hear the usual rushing water sound at the start of the cycle.
Error appears within first few minutes
The F4-E3 code displays shortly after pressing Start, during the initial fill stage.
Possible Causes
Water supply valve closed
The shutoff valve under the sink or behind the dishwasher is partially or fully closed.
DIY PossibleClogged or failed water inlet valve
Mineral deposits have restricted flow through the inlet valve solenoid.
Requires ProfessionalSafe Checks You Can Do
-
1
Verify water supply is on
Check the shutoff valve under the sink — turn it fully counterclockwise to ensure full flow.
Run the kitchen faucet hot before starting a cycle to confirm strong water pressure.

2
Inspect the fill hose
Pull the dishwasher out enough to check the fill hose for kinks, and verify the screen filter at the inlet valve is not clogged.
A small wire mesh screen inside the valve connection catches debris — clean it with a toothbrush.
Tools required
When to Call a Professional
Contact a qualified technician if:
- Inlet valve gets power but does not open
