Washer-dryer does not fill with water or fills very slowly; program stops early with E02

Safety first: Unplug the appliance and close the water tap before disconnecting hoses.

Step-by-step checks:

• 1. Verify water supply:
  • Ensure the wall tap is fully open.
  • Check household water pressure by filling a bucket from the tap; weak flow indicates a plumbing issue.
• 2. Clean inlet filters:
  • Turn off the tap and unscrew the AquaStop or standard inlet hose from the tap and from the machine.
  • Remove the small mesh filters from both ends (tap and machine side) with needle-nose pliers.
  • Rinse under running water and brush off limescale or debris.
  • Reinstall filters and reconnect the hose firmly.
• 3. Check AquaStop / inlet valve:
  • With the top cover removed (unplugged), locate the AquaStop valve or internal inlet valve block.
  • Inspect for visible cracks, leaks, or burnt connectors.
  • Measure coil resistance with a multimeter; if open circuit, replace the valve assembly.
• 4. Inspect pressure sensor and hose:
  • Locate the pressure sensor (usually mounted on the side wall or near the control module) and its thin air hose to the tub.
  • Check the hose for kinks, blockages, or splits; clean or replace as needed.
  • Ensure the connector to the sensor is secure.

When to call a technician: If the AquaStop system is integrated and sealed, or if the control module is not energizing the valve, professional diagnosis is recommended.
