Symptom / Description

FAULT

Leakage detected / AquaStop activated

TELEMETRY // LIVESIG: FAULT_DETECTED

Root Cause

ROOT CAUSE

Water has collected in the base pan of the appliance, tripping the flood protection float switch.

CIRCUIT // SUBSYSTEMLOGIC: ROOT_ISOLATED

Repair Instructions

UNLOCKED

1Unplug the appliance. Carefully tilt it backwards to drain the water from the base. Locate and repair the source of the leak (e.g., hose, pump seal, tub seal).

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: Schulthess F23

FAQ TREE

What does error code F23 mean on a Schulthess appliance?

Schulthess error code F23 indicates: Leakage detected / AquaStop activated.

What is the root cause of Schulthess error code F23?

The primary root cause for Schulthess code F23 is: Water has collected in the base pan of the appliance, tripping the flood protection float switch..

How do I fix or resolve Schulthess error code F23?

To resolve error code F23: Unplug the appliance. Carefully tilt it backwards to drain the water from the base. Locate and repair the source of the leak (e.g., hose, pump seal, tub seal).

Is it safe to clear Schulthess error code F23 by resetting power?

Resetting power (unplugging for 5–10 minutes) clears temporary memory errors. However, if Schulthess code F23 persists, the physical component causing Water has collected in the base pan of the appliance, tripping the flood protection float switch. must be inspected or replaced.

How do I test electrical resistance for Schulthess code F23 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 Schulthess code F23?

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.
