ASKO 3350 Dishwasher F4 After About 60 Seconds of Filling

An ASKO 3350 that fills for about 60 seconds and then stops with F4 should not be diagnosed from the timing alone. ASKO's opened US cleaning guide places F4 in its no-water section: verify the accessible water shutoff is open, document the code, and use the guide's five-second Start/Stop reset only once if the unit is dry and there is no leak or other hazard.
