Dishwasher stops and displays i50; may not circulate or drain water properly.

Safety first: Turn off power at the breaker. Water may be hot inside the tub.

• Reset attempt: Leave the dishwasher powered off for 10–15 minutes, then restore power and try a short program. Sometimes transient control errors clear with a reset.
• Listen to pumps: Start a cycle and listen: if you hear no circulation noise and only a faint click, the circulation pump may be seized. If it will not drain and you hear only humming, the drain pump may be jammed.
• Check for obstructions: Remove filters and inspect the pump impeller area for foreign objects (glass, bones, seeds). Remove debris carefully.
• Inspect wiring (advanced): With side or bottom panel removed, check the wiring harness to the circulation and drain pumps for burns, loose connectors, or damage.

If i50 remains after clearing obstructions and resetting, the circulation pump, drain pump, or main control board may require replacement. This is typically a technician-level repair.
