Good morning, I am a retired appliance engineer now living abroad and a friend asked me to repair a leak on their DFN16420B beko dishwasher. The leak was on the drain hose so I simply replaced it, (5 minute job). Now the appliance will fill, heat, and empty but won’t wash. It has an inverter wash pump so no chance of checking the electronics on it. I’ve checked the obvious, flood switch, loose plugs, etc. Can anyone assist me with this fault please? Thank you in advance.
