My beko 5410 dishwasher has stopped working properly?

At some point during a cycle my dishwasher stopped working. It did not drain the water, and instead kept churning the water in the bottom every couple of seconds whilst all the lights flashed on and off in time to the churning of the water. Now when I try to put it on, I may get a couple of minutes of it working before it reverts back to the lights flashing on and off and the water at the bottom churning.
