Rinse pump or rinse solenoid fault; display shows E8 and no final rinse water sprays.

Safety first: Turn off power and close the rinse water supply. Hot water under pressure can cause burns.

Step-by-step checks:

• Inspect rinse nozzles: Remove and clean the final rinse nozzles. Mineral scale or debris can block spray and mimic a pump/valve failure.
• Check rinse line strainer: Locate and clean the rinse line strainer or filter. Flush with water to remove sediment.
• Test rinse solenoid valve: With power OFF, check the coil for continuity. Inspect for scale buildup or a stuck plunger. Replace the valve if the coil is open or the valve is mechanically stuck.
• Rinse pump (if installed): Verify the pump spins freely and is not leaking. Test motor windings with a meter. Replace the pump if seized or electrically open.

When to call a technician: If the control board is not energizing the rinse circuit or if plumbing modifications are needed, contact a CMA service technician.
