I have just bought a second hand Bosch diswasher and the grey waste pipe that comes out of the machine has a "knob" on the end that is too small a diameter to fit onto the horn attachment under the sink. I have looked in the DIY shops and can't find an attachment that fits under the sink with a smaller diameter. Am I missing something, or do I just cut the "knob" bit off to leave the corrugated plastic which "should" fit on the horn?
Trouble is, once I've cut it off, there's no going back!
I have overcome the problem by fitting a old style hose fitting (non threaded taps) for garden hoses (rubber end with built in clamp)and clamped it on to the hose and then onto the drain pipe. Available Bunnings for $10.00

You said you had water under the dishwasher,did you remove the lower panel below the door and check for water in the base frame as well. Bosch dishwashers have system in the base frame that detects water in base and cuts power off to every component except drain pump till it no longer sees the water in the base.
Waste line from dishwasher to waste connects to one of
small spigot on extension pipe above the disposal up high under counter
small spigot on side of disposal directly above sewer connection, below blade
small spigot on sewer line below disposal, but above U trap
at the dishwasher end, the hose connects to the pump output, under the base of the dishwasher, usually left side of center, there is no external spigot
you have to run the waste line under from the back, and connect from the front , by removing the kick plate under the door opening
On the left hand side you will see a clear plastic panel full of tubes and small tanks. This is the metering tank. At the bottom left of this unit, is a black pipe held on with a clip. There will almost definately be a blockage between this point and the sump. You can either buy and fit a new pipe or do what I did with mine, which was to remove it and clean it with hot water and a bottle brush. Seems to work like new again now.
You'll have to get the machine onto it's right side to remove the lower end of the black pipe from the sump. I drained as much excess water as possible out of the machine by sitting it on bricks, tilting it to the left and catching the water in a dish as it came out of the float hole. Some will also come out of the funny plastic tube which runs across the top of the machine - I carefully removed this first and caught this water in a pan.
Drain the waste pipe and disconnect the water supply.
Replace the right side casing on to protect the feed to the upper spray unit and put the machine on it's right hand side. Once the machine is on its right hand side, fin the water inlet valve and carefully remove its bracket from the chasis of the machine. You will need cross head and a torx screwdrivers - one for each screw. Once this is loosened, push some of the water supply pipe into the machine so you can move the bracket to the right a little to gaine access to the waste pipe. Remove this by removing the two gold coloured screws. This should now give you easy access to the sump end of the black pipe which lead from the metering tank. Remove this and clean it out. Pop all the parts back, stand you machine upright. Reconnect the watre supply and the waste and give it a rinse cycle to test - number 1 on the dial.
Hope this helps. My apologies if any of the take apart is not completely accurate - I don't want to turn my machine over again to check!
Did you have a dishwasher before? If so, you must have had a sink tail piece with a dishwasher drain coming off the side. For the connection, you may have to get an adapter to fit the end of the dishwasher drain hose to the sink tail piece. Take all pieces to hardware store if necessary to get an adapter which fits. After you connect the drain hose, make sure that the drain hose has a "high loop", meaning that the hose curls up at least 6 inches above the connection point before it goes down again. This is important to keep sink waste from getting back into the diswasher hose if the sink drain backs up.
remove the kick plate below the door. youll see a white tray behind the kick plate. theres water in the tray thats activating a overflow switch. with a towel or 2 remove as much water from tray as possible. this will solve problem
