Miele G5210SC Error F13: Dishwasher Diagnosis and Solutions

⚠️ SAFETY WARNING / ELECTRICAL RISK. Before performing any physical work on the dishwasher, disconnect the 230V power supply via the main circuit breaker and turn off the water tap to prevent electric shock or flooding. ReeFix provides this diagnosis EXCLUSIVELY for educational and informational purposes.

REQUIRED TOOLS

• Miele G5210SC Aquastop solenoid valve filter
• Miele G5210SC Aquastop WPS inlet hose
• Miele G5210SC Reed flow meter sensor
• Miele G5210SC Air Gap side matrix
• Professional digital multimeter
• Long-nose pliers for filters

STEP 1: Water inlet checks (DIY: 55-60% of causes)

Error F13 indicates a water fill timeout: the control board expects filling within 2-4 minutes, but the flow rate is insufficient.

1. Wall tap test: Turn off the water, unscrew the inlet hose from the wall, and dispense water into a graduated bucket. The flow rate must exceed 5 liters per minute (minimum pressure 0.3-0.5 bar).
2. WPS micro-filter cleaning: Remove the mesh filter located inside the 3/4" collar of the Aquastop using long-nose pliers. Remove limescale and rust sediment.

This often happens when... after work on the local water network or prolonged periods of disuse, debris is pushed directly against the solenoid valve mesh filter, blocking up to 80% of the water flow.

STEP 2: Electromechanical diagnosis (Requires Multimeter: 40% of causes)

If the wall pressure is correct and the filter is clean, the fault lies in the measuring or flow-opening components.

1. Aquastop Solenoid Valve Test (WPS):

   • Disconnect the dishwasher from the power supply.
   • Access the WPS unit connector in the base and measure the resistance of the two coils using a professional digital multimeter.
   • Reference value: ~2.0–2.5 kΩ for each coil. If the reading shows infinite value (open circuit) or close to 0 Ω (short circuit), the Miele G5210SC Aquastop WPS inlet hose must be fully replaced.

2. Flow Meter and Air Gap Side Matrix Inspection:

   • Water enters but the machine still triggers error F13? The liter counter sensor is not sending pulses to the board.
   • Check that the impeller inside the Miele G5210SC Air Gap side matrix rotates freely and is free of limescale deposits.
   • Check the pulsed continuity of the Miele G5210SC Reed flow meter sensor as water flows through.

If during the fill cycle the dishwasher shows anomalies related to pressure or the level pressure switch, also consult our diagnosis on Miele G 4203 SC Error F14: Diagnosis and Solution.

Summary for your trusted technician:

Error code F13 on Miele G5210SC. Wall tap pressure verified. Check resistance value on double WPS solenoid (expected ~2.2 kΩ) and switching continuity of the flow meter reed sensor on the air matrix.

FINAL VERIFICATION

Reassemble the components, turn the water tap back on, and start a short rinse cycle. Make sure the initial count does not stall and water fills normally within 60 seconds of starting without triggering alarm F13 again.

If cleaning the inlet filter does not resolve the alarm -> check WPS assembly resistance: if winding is open, replace the Miele G5210SC Aquastop WPS inlet hose; otherwise, replace the Miele G5210SC Reed flow meter sensor.
