Symptom / Description

FAULT

The washing machine does not work. No error code is displayed, or error code E23 is displayed instead of error code EF3 (Water Protection System). The washing machine interrupts the current program and starts the safety drain cycle. Water is drained, and the machine stops with the door locked. If the temperature in the drum is too high, water is drained to 2/3 full to reduce the temperature before the door can be opened.

TELEMETRY // LIVESIG: FAULT_DETECTED

Root Cause

ROOT CAUSE

Due to a software error, error code EF3 (in the service test program) and the corresponding error code EF0 (on the display) are not shown. Instead, error code E23 is displayed in the service test program. The underlying issue that EF3/EF0 would indicate is a water leak or leakage, related to the water protection system.

CIRCUIT // SUBSYSTEMLOGIC: ROOT_ISOLATED

Repair Instructions

UNLOCKED

1Start the service test program (refer to the corresponding service manual). 2. Skip the first steps in the service test program and set the program selector to 'error code display'. 3. Check if error code E23 is stored (check all 3 error codes). 4. If error code E23 is present, check the machine for water leaks/leakages. 5. If no water leak/leakage is found, continue troubleshooting normally as if looking for error code E23 (according to the procedure in the service manual).

1. Pre-Intervention Electrical Safety Protocols

!Electrical Safety Protocol: Isolate 230V mains power before accessing the lower pump housing.
!Prepare a shallow basin and absorption towels: expect 3 to 10 liters of stagnant trapped water upon filter opening.
!Beware of sharp foreign objects (broken glass, needles, screws) trapped inside the impeller cavity.

3. Preliminary Mechanical & Visual Checks

Unscrew coin trap filter and clear all foreign debris (coins, hairpins, bra underwires).
Rotate pump impeller manually: synchronous magnetic rotors should snap cleanly in 90° intervals without jamming.
Check drain hose for kinks, blockages, or unpunched sink spigots; verify drain height is between 65cm and 100cm.

Frequently Asked Questions: Princess E23

FAQ TREE

What does error code E23 mean on a Princess appliance?

Princess error code E23 indicates: The washing machine does not work. No error code is displayed, or error code E23 is displayed instead of error code EF3 (Water Protection System). The washing machine interrupts the current program and starts the safety drain cycle. Water is drained, and the machine stops with the door locked. If the temperature in the drum is too high, water is drained to 2/3 full to reduce the temperature before the door can be opened..

What is the root cause of Princess error code E23?

The primary root cause for Princess code E23 is: Due to a software error, error code EF3 (in the service test program) and the corresponding error code EF0 (on the display) are not shown. Instead, error code E23 is displayed in the service test program. The underlying issue that EF3/EF0 would indicate is a water leak or leakage, related to the water protection system..

How do I fix or resolve Princess error code E23?

To resolve error code E23: 1. Start the service test program (refer to the corresponding service manual). 2. Skip the first steps in the service test program and set the program selector to 'error code display'. 3. Check if error code E23 is stored (check all 3 error codes). 4. If error code E23 is present, check the machine for water leaks/leakages. 5. If no water leak/leakage is found, continue troubleshooting normally as if looking for error code E23 (according to the procedure in the service manual).

Is it safe to clear Princess error code E23 by resetting power?

Resetting power (unplugging for 5–10 minutes) clears temporary memory errors. However, if Princess code E23 persists, the physical component causing Due to a software error, error code EF3 (in the service test program) and the corresponding error code EF0 (on the display) are not shown. Instead, error code E23 is displayed in the service test program. The underlying issue that EF3/EF0 would indicate is a water leak or leakage, related to the water protection system. must be inspected or replaced.

How do I test electrical resistance for Princess code E23 using a multimeter?

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..

What safety protocol must be followed before servicing Princess code E23?

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.
