Dishwasher displays C8; may indicate a problem with detergent or rinse aid dispensing.

Safety: Turn off power before removing the inner door panel.

• Inspect the dispenser door: Open the dishwasher door and check that the detergent cup opens freely by hand. Clean any caked detergent from the cup and surrounding area.
• Check for mechanical obstruction: Ensure that tall dishes or utensils in the lower rack are not blocking the dispenser door from opening during the cycle.
• Access the dispenser assembly: Remove the inner door panel screws to expose the back of the dispenser. Inspect the latch and spring for damage.
• Test dispenser solenoid or wax motor: Disconnect the wires and measure resistance. An open circuit indicates a failed dispenser mechanism that should be replaced.
• Replace dispenser assembly if needed: If the mechanism is broken or the solenoid is open, install a new GE detergent/rinse aid dispenser assembly.
