Fit a new waste pipe?

If you buy a similar model from the same manufacturer, you can leave the sink fittings in place. Unplug the power and disconnect the waste pipe. Undo the bayonet fitting securing the waste disposal unit to the sink fitting. Fit new unit to sink fitting, reconnect waste pipe and power. Run the unit with plenty of water to check for leaks. Job done.

Yes the cold water pipe as the new models only have one supply. You connect the pipe to a cold water supply it then goes into the dishwasher and the machine heats the water up to the required temperature. Don't forget to fit the drain pipe into your waste pipe also to take the dirty water away.

Pour some bleach into the stinky backwash. I know that this is not good for the environment but it will take the stench away while you get a new dishwasher. Sorry but you have plumbing problems out of my range.

more info needed like how many pipes. however you should have 3 pipes . 1 red , 1 blue and 1 other .
the red connects to your hot water supply
the blue connects to your cold water supply
and the other pipe should come from the bottom of the machine and is your waste which will need to be connected to the sink waste or another waste pipe.you must ensure the waste pipe is fitted otherwise when you run the machine it will empty on to the floor

check inside the end of the waste pipe, i recently bought a new washing machine and had a similar problem, and checked the waste pipe last. inside the waste pipe was a plug, hope this helps you.

1. Waste Disposal/Sink trap
   • Empty your food waste disposal unit if your dishwasher's hooked up to one. If it's not empty, the old food inside it will back water up into your machine. Check that your sink trap isn't blocked by unscrewing it from the base of your sink if you don't have a food waste disposal unit. Make sure your dishwasher or any other appliances connected to it are not running when you do so.
     
   Incomplete Cycle
   • You may have opened your dishwasher's door mid-cycle before it's had a chance to drain. Check the progress indicator on your machine's control panel. The structure of this will differ depending on which Frigidaire model you're using, but it should show the point your machine has reached in its cycle. If this is the cause of the problem, close your dishwasher's door and let it finish.
     
   Drainage Pipe
   • Inspect the drain pipe that runs from your machine to your waste disposal unit or sink. If this is kinked or has been squashed under another appliance or a base unit, the waste water inside your dishwasher will be unable to escape. Check that water can flow through your waste pipe freely.
     
   Filter
   • Remove the bottom shelf from inside your machine and take out the plate covering the filter area. If you don't rinse your plates before you put them into your washer, food debris could block your filter and stop water from reaching your drainage pipe. You can unblock your filter with your fingers. Turn off your machine's power before you attempt to do so.
     

It is not advised to adjust connections.
I suggest you buy a fitting that is at 30 degrees, or one that is adjustable between 0 and 90 degrees.
These are available for waste pipes.
Failing that, PS waste pipe can be bent with a hot-air gun, and new connections made further away - but I'd go with getting the right connection.

You need to get a one way valve fitted in the pipe just before it hits the main waste pipe. This will ensure that as soon as any backpressure is exerted that the valve closes and your sink etc will not fill with waste. This is a potential health hazard to you so I would suggest it is fitted ASAP.

the error is caused by a blockage in the pump you need to drain the washer using the black tube near the pump drain or by unscrewing the pump cover next to it on excel 8kg washer these are at bottom right of machine. when all water out remove pump cover that you loosened to get water out then check for blockages inside. the pump has a device inside that should move round freely remove all debris replace and try to drain using drain cycle this will finish and hey presto back to normal!!

you haven't said a make and it is presumably a washer but:
waste pipe clips usually onto a spigot on the pump housing. should be accessible by tilting machine backwards. on some machines easier to remove the back plate
