Dishwasher adp 4601 when switched on the pump activates.and after 2 mins start lamp bliks and pump goes off

The number of flashes indicates the fault. Reset machine by holding down the start button for 3 secs, then start a new cycle. If fault reoccurs, the number of flashes indicates fault eg 3 flashes, stop, 3 flashes stop, indicates F3 fault.
Faults listed below- advice on repair depends on which fault your machine is indicating, but may give you an idea of what to look for
1flash=NTC (temperature sensor) break- NTC outside normal range.
2flash=water leakage-float switch in base activated.
3flash=heating fault(check element.NTC,control board).
4flash=drain error-blockage in pump or drain system,or faulty water indicator switch.
6flash=water inlet fault-check inlet valve, check inlet hose not kinked
7flash=flow meter failure (flow meter measures water intake volume-large plastic weir located on left hand side of machine-reomve side panel to access)
These a most common faults, but further advice on repair requires counting flashes when fault occurs.
