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.
Record the code
Photograph the display or count the full flashing pattern.
Cancel safely
Allow any drain routine to finish and check for visible water.
Reset once
Switch the dishwasher circuit off for 30 seconds, then restore power.
Stop if it returns
Do not remove the dishwasher or access internal components.
Know where to stop
Dishwashers combine water, heat, and line voltage. Internal component checks belong to a qualified technician.
When to call a technician or support
Contact the manufacturer or an appliance technician when the component code returns after one reset.
When you call, have the exact product model, the complete code or light pattern, and when it appeared.
