Show stop conditions
  • The inlet hose or valve leaks
  • Water continues entering when power is off
  • Internal valve or electrical testing is required

Likely causes

  • The water supply valve is closed
  • The inlet hose is kinked or restricted
  • The door latch is not confirming closure
  • The overfill float is stuck in the raised position
  • The inlet valve, wiring, or control has failed

Quick checks, in order

Open the supply valve fully

Verify water is available at the sink.

safe

Inspect the inlet hose

Check for kinks, crushing, freezing, or a leak-stop device that has activated.

safe

Check the door and float area

Remove obstructions and confirm the user-accessible float moves as described in the manual.

Listen during the fill stage

A hum with no water suggests a supply or inlet restriction; silence may indicate a control or valve issue.

What happens after the drain stage?

You hear a valve hum

Check the supply valve, hose, pressure, screen, and inlet path.

There is complete silence

The latch, float switch, inlet valve, wiring, or control may need diagnosis.

Only a small amount of water enters

Low pressure, a restricted inlet, or an early level-sensing signal is possible.

Stop and get qualified help when

Do not continue troubleshooting if any of these apply:
  • The inlet hose or valve leaks
  • Water continues entering when power is off
  • Internal valve or electrical testing is required

Frequently asked questions

Does a dishwasher fill all the way to the door?

No. Modern machines use a relatively shallow amount of water below the door opening.

Can a stuck float stop filling?

Yes. If the overfill system indicates a high water level, the control may keep the inlet valve closed.

Keep diagnosing

Dishwasher does not clean well

Blocked spray arms, incorrect loading, low water temperature, weak filling, poor detergent use, or a circulation problem can leave food and film on dishes.
