Disconnect dishwasher from mains

BarraOG · 30-07-2023 6:29pm #1

I need to install a new dishwasher. I’ve turned off the compression valve but Im not sure how to disconnect the dishwasher hose from this valve. Can it be done safely? The damage visible to the red and blue plastics suggests the valve was held in place, while a visegrip was used to tighten the red connector to it. For this reason I think the valve might disconnect from the white pipe above it if I try turning the red connector clockwise with the required force. I’m therefore thinking I’ll need a plumber to connect it again and should just cut the dishwasher hose to disconnect the dishwasher so I can dump it while waiting for the new one. What would you do?

Should be able to loosen the red connection with a pair of pipe grips if you hold against it by gripping the centre of the valve. Can't see the other side pulling off as it looks like a compression fitting.

Anti-clockwise to loosen!

Yeah, just vice-grip on the red side and adjustable spanner on the flat part of the valve (from the top down its flat and can be held in place)

Or, turn off the water and replace the valve in one go (as its cracked and going to break off anyway!)

Thanks for the reply. I’m doing as you say and I can move the red connector fine. Isn’t it clockwise though? The red connector is below the valve so in my mind it’s like holding a bottle upside down and turning the the lid clockwise to remove it. Isn’t it the same principle?

The red female bit screws onto the male brass valve, so as you look at the photo you unscrew it clockwise. The female nut connecting the white pipe to the other side of the brass valve unscrews anti clockwise.

Hope you get sorted.

Anyone know what that white box bit does, only ever saw one on Miele dishwashers, ours is about 30 years old and will need replacing soon and I was wondering do I connect new one to white box or remove it?

Pretty sure it's an aquastop. Solenoid valve, think it only lets water through when the dishwasher is on.

I tested a cycle before unscrewing the hose and noticed the dishwasher is filling. Maybe that means there is dirt in the mechanical valve. So I disconnected the hose inside the dishwasher instead. At this point you can see a wire concealed within the hose which is obviously feeding that electrical valve. Anyway, I will wait for the new machine to come, turn off the water and unscrew the red connector then. Hopefully all goes well.

Well if you are looking at it from upside down, then yes it will be backwards :)
