How Do I Disconnect A Bosch Dishwasher & Reconnect A New Bosch In The Uk?
There is a gray area at the rear which has a symbol of the tension and the water pipe also seems to be connected to this case. My new dishwasher is a Bosch. Old and new are both independent.
The grey box with the voltage symbol indicates that this machine utilises an antiflood mechanism. In the event of the dishwasher over filling, the float switch in the base of the dishwasher will signal the grey box to isolate the water supply. People often mis-diagnose a faulty dishwasher by over looking this safety feature.
Isolate both the electrical and water supply to the dishwasher before undertaking any work on this machine.
Physically remove the three pin plug from the wall socket and turn off the water isolating valve. Use a pipe pliers to unscrew the brass nut on the end off the grey box.
If you have a tiled or wooden kitchen floor, try putting a dab of liquid soap on the floor near to the dishwasher feet. It will make it easy to slide the dishwasher out as you try to remove it.
When fitting the new dishwasher remember to level the machine using the adjustable feet. I like to have the machine tilting slightly to the rear only 1 or 2 degrees max. The idea here is if your machine generates a lot of suds during normal operation, the excess volume won’t fall into the drip tray in the base of the machine and thus activating the antiflood system.
Now reconnect all services and you’re good to go.

Hope this helps!
The older dishwashers are a cold or dual fill, some more modern ones are a hot fill, a plumber would charge between £65 and £150 so what are you messing with it for, surely if you can afford an exxcellent choice like Bosch, you can afford to complete the job properly!
Dishwashers need a cold water supply, and electricity supply, and a waste outlet.
Before doing *anything* remove the plug from the mains supply.
The cold water supply should have a screw connection at the back of the dishwasher. You might need pliers or a mole grip to undo this.
The waste pipe can either go into the top of an open down-pipe, or connect into the waste pipes under the sink. The waste pipe cannot be disconnected from the machine usually.
It’s fairly straight-forward when you know what you are dealing with.
You should not be touching the back of the machine there should be a water pipe that is going from the dishwasher to a water pipe that is on screw fittings. Usually under a sink or at the back of the machine. Make sure you turn off the water by turning the connector to the off position (straight across usually)it will probably be a blue one. Unscrew and disconnect the pipe. There will be an outlet hose (waste) inserted into a pipe this will probably be next to the water supply pipe or it may be connected to under the sink. Then your electric plug. Pull out when each disconnected then reconnect your new one ensuring that all pipes tightened to ensure no leaks……..And just in case when new one fitted in place don’t forget to turn the water back on at the water connector LOL
You must turn off water supply at the mains, this will allow you to disconcert the water supply, from the pipework. This is done by using a pair of water pump pliers. Undo the plastic nut that connects to the mains usually a plastic flex able pipe,and then disconnect the waste pipe that will probably be connected to either its own pipe or the trap under the kitchen sink. You will have to isolate any electrical supply at the meter, and then disconcert the three wires from the supply (live , neutral, earth) and connect new appliance in reverse order. If i doubt contact a professional.
