Washer-dryer reports E14; issues with water level detection during drying or wash

Safety first: Unplug the appliance and close the water tap.

Step-by-step checks:

• 1. Check inlet filters and pressure:
  • Clean mesh filters at the AquaStop hose and machine inlet.
  • Ensure adequate water pressure at the tap.
• 2. Inspect flow meter (if integrated):
  • On many Siemens units, the flow meter is built into the AquaStop or inlet valve block.
  • Check the small wiring harness from the valve to the control module.
  • Look for damaged or loose connectors.
• 3. Replace AquaStop / flow meter assembly if faulty:
  • If the flow meter does not generate pulses (requires service test), replace the complete valve/flow meter unit.

When to call a technician: Flow meter diagnosis often requires service mode and specialized tools; professional service is recommended if basic checks do not resolve the issue.
