Just fitted an intergrted Bosch dishwasher for a friend, its fitted directly next to the sink cupboard. The drainage hose is fed down to floor level, uder the cupboard where it enters under the sink. It comes up and is connected to the P trap on the sink via an appliance nosel. The problem is that after a cycle it does not drain properly and there is water in the bottom of the machine up to the bottom of the door. Annoying when you open it and water leaks onto the floor. I should mention thats its a second hand machine with no instructions. Is it not draining because of the routing of the waste pipe? Any ideas?
