Dishwasher displays E16 and may not fill correctly; sometimes fills continuously or not at all.

Safety first: Disconnect power and close the water tap before handling the inlet hose.

• Inspect Aquastop hose: Check the external Aquastop box on the inlet hose for damage or signs of overheating.
• Check for continuous filling: With power off and water tap open, see if water continues to enter the dishwasher. If so, the valve is mechanically stuck open and must be replaced immediately.
• Test valve coil: Remove the lower panel to access the inlet valve (if not integrated in the hose). Measure coil resistance with a multimeter. Replace if open circuit.
• Replace Aquastop/inlet valve: If the valve is stuck or electrically faulty, install a new Arcelik-compatible Aquastop hose or inlet valve assembly.
• Control board check: If a new valve does not resolve E16, the main PCB may not be controlling the valve correctly and may require professional service.
