Safe checks, in order
Start with the simplest non-invasive check. Stop as soon as the error clears; repeated resets can hide a condition without correcting it.
Check the supply
Confirm the dishwasher water valve is fully open.
Inspect the accessible hose
Look for a tight bend or damage without pulling out the machine.
Check household flow
Verify the nearby sink has normal water pressure.
Restart once
After correcting an obvious issue, reset power for the interval stated by the manufacturer.
Know where to stop
Turn off the circuit and water supply before reaching beneath the dishwasher. Do not move a hardwired unit while energized.
When to call a technician or support
Request service if supply and hose conditions are normal but the fill code returns.
When you call, have the exact product model, the complete code or light pattern, and when it appeared.
