I had a problem with my beko dishwasher. kept trying to empty the machine in the middle of the washing cycle. a repairman visited us 3 times at last found out that the brightener liquid foams at the last rinse. the foam flows thru the overflow tube to the overflow sink at the bottom of the machine, makes the safety float thingy there rise a bit and begins to empty the machine as a safety precaution.
Put the brightener dosage to 0, try again once the water in the overflow sink has dried out (or open the front down panel and dry it up yourself). If the machine works increase the dosage until you wind the correct amount.
Hopefully this works
