Zoppas E23

Zoppas error code E23 indicates: Zoppas PWF Series / Armonia Elettronica Washer: Drain pump triac failure E23; pump runs continuously or triac circuit detects short circuit on main PCB..

The primary root cause for Zoppas code E23 is: On Zoppas (Zoppas PWF Series / Armonia Elettronica Washer) models: Electronic triac on main control PCB damaged by short-circuited drain pump coil (excess current > 2A) or moisture ingress at pump spade terminals..

To resolve error code E23: Check drain pump stator coil resistance before replacing PCB (if < 150 Ω, replace pump first!). Inspect PCB triac circuit for burned trace. Hold Avvio/Pausa and Annulla simultaneously for 5 seconds until the acoustic triple beep confirms memory clearing.

Resetting power (unplugging for 5–10 minutes) clears temporary memory errors. However, if Zoppas code E23 persists, the physical component causing On Zoppas (Zoppas PWF Series / Armonia Elettronica Washer) models: Electronic triac on main control PCB damaged by short-circuited drain pump coil (excess current > 2A) or moisture ingress at pump spade terminals. must be inspected or replaced.

Set a digital multimeter to ohms (Ω). Disconnect power and test Drain Pump Motor Stator Coils across Across pump motor spade terminals (L-N unclipped). Expected nominal reading is 160Ω–220Ω (Sync 230V) / 20Ω–45Ω (3-Phase BLDC). Tolerance: ±10% balance. Insulation resistance between coil and motor chassis must exceed 20MΩ..

Standard electrical safety protocol: 1. Disconnect 230V mains power before opening panels. 2. Verify zero voltage at test points. 3. Allow hot water or heating elements to cool below 30°C before handling.
