Electric water pipe?

Ginger-Menace · 9 Jan 2020 at 12:15

recently moved in to our new house.
Looking under kitchen sink, this is the water pipe that connects to the dishwasher.
Can anyone tell me what this connector is and why it has an oily residue coming from it (the big grey block)?

TIA

Could it be for preheating the water? Are you in a hard water area?

Could it be some sort of ultrasonic transmitter to break down the hard water to prevent scaling in the dishwasher?

Looks a bit like a safety valve from their website

Anti-flood Aquastop appliance hose?

So it's to stop flow back into the dishwasher. Huh I would have thought a simple mechanical non return valve would be easier.

Im not sure, the wording is a bit odd, but I read it as if its not active its by default off, so a bit like a tap itself.
So when dishwasher is on its open and when turned off its off, so you cant get a water leak.

Seems a bit unnecessary but seems to be fitted to german models so maybe its a local requirement for their machines.

Thanks for this! had a look and your right, it is one of these. Basicly if the hose between this and the dish washer breaks it shuts off the water!
Thanks every one!

Could it be a bit more of a domestic RPZ?

I've seen then called aquastop valves.
