Important Tips for GE Models

  • Codes such as C1–C8, H2O, PrS, 999 are specific to GE electronic control diagnostics

Possible Causes

Drain system faults (e.g., C1, C2, C3)

Part: Drain hose / drain pump / air gap

Water inlet or supply issues (e.g., H2O / E1)

How to Identify: H2O or E1 appears when low water condition or water fills too slowly, often with little/no water entering the dishwasher.

Part: Water inlet valve / supply hose / float switch

Detergent dispenser error (e.g., C8 or Cup Open)

How to Identify: Dispenser fails to open fully or stays open; Cup Open shows when detergent door not latched. (GE Appliances

Part: Detergent dispenser mechanism

Leak detection (e.g., LEAK DETECTED / 999)

How to Identify: Leak code displayed; dishwasher may stop mid‑cycle; water in base pan. (GE Appliances

Part: Leak sensor / base pan flood switch

Pressure sensor invalid signal (PrS)

How to Identify: PrS appears when the pressure sensor sends an invalid or out‑of‑range signal. (GE Appliances
