Frequently Asked Questions

Can I keep using my GE Appliances Dishwasher when error C3 appears? +
It is not advisable. The dishwasher may still power on, but running it while C3 is active can worsen the control-board fault or damage related parts. Treat it as a soon-as-possible repair.
What most commonly causes C3 on a GE Appliances Dishwasher? +
Across reported GE Appliances dishwasher repairs, the most frequent is board component failure (55% of cases), power surge (30%), then moisture damage (15%). Check them in that order before replacing any parts.
C3 keeps coming back after a reset — what should I check next? +
A reset only clears the stored C3 fault; if it returns, the control-board problem is still present. Move on to the physical checks — power-cycle the dishwasher, then check for moisture intrusion — since the code will reappear until the root cause is resolved. This is an advanced repair involving deeper disassembly or electrical testing.
How much does it cost to fix GE Appliances Dishwasher error C3? +
