Step 01
Signs
• Dishwasher stops mid-cycle and displays C8 error code on control panel
• No water spraying from upper or lower spray arms during wash cycle
• Dishes remain unwashed or only partially cleaned
• Humming sound from motor area but no water circulation
• Error code may appear intermittently or persistently
• Dishwasher may not start a new cycle until error is cleared
• Water drains normally but circulation does not occur during wash phases
Step 02
Possible Causes
• Wash motor has failed or is not receiving proper 120V electrical power
• Circulation pump impeller is broken, damaged, or jammed
• Debris, food particles, or mineral buildup blocking the pump intake
• Loose or corroded electrical connections to the motor or pump
• Defective door latch preventing proper cycle engagement
• Control board failure preventing motor activation signal
• Clogged or kinked inlet hose restricting water to the pump
• Worn pump bearings causing motor to seize
Step 03
Safety Checks You Can Do
• Check your home's circuit breaker to ensure the dishwasher breaker is in the ON position; reset if tripped
• Turn off the dishwasher and allow it to sit for 60 seconds, then turn the breaker off for 60 seconds before turning back on to perform a full reset
• Verify the dishwasher door closes completely and latches firmly with an audible click
• Open the dishwasher and inspect the upper and lower spray arms for debris, food particles, or mineral deposits; clean spray arm holes with a small brush or pipe cleaner if needed
• Check that spray arms rotate freely by hand when you gently spin them
• Remove and rinse the dishwasher filter at the bottom of the tub to ensure no blockages
• Inspect the dishwasher interior for foreign objects such as broken glass or utensil fragments that may have fallen into the pump area
• Ensure water inlet hoses connected to the back of the dishwasher are not kinked, twisted, or pinched
• Run a cleaning cycle with white vinegar in a bowl on the top rack to help dissolve mineral buildup in the pump system
• Check that your control panel settings are correct and you are selecting an appropriate wash cycle before starting
• If error persists after these checks, contact GE customer service or a certified USA technician for motor and pump diagnostics
