Looking for a plumbing part...

You need cold for the dishwasher, they nearly always require cold fill only.

Are you sure about the hot only, most washing machines take either hot and cold or cold only.

Most (European) dishwashers will accept a single hot feed. However, it will usually make it more expensive to run and result in less perfect cleaning results, although it will complete a cycle more quickly. A US dishwasher requires a hot supply and will not work with a cold supply.

Dish washers should ideally be plumbed with a cold water feed if yours has a rinse & hold programme. The thinking is that a hot feed on a rinse & hold prog tends to bake the debris onto the plate.

Out of interest I've just bought a new washing machine (Siemens) Seems like most manufacturers are now making washing machine cold fill only, as the washing performance is better. The ones we looked at, were Bosch, Miele, AEG and Siemens and all were cold fill only. It's a bit annoying as the wash takes longer and obviously costs more as you are using electricity to heat the water rather than gas. As all these makes are German, perhaps it's a conspiracy!

Not convinced it is more expensive - a modern dish washer uses so little water that they are full before the hot water ever gets to them. You end up using gas to heat the pipework up a bit and then electric to heat up the cold water that was standing in the pipework.

One of the reasons I bought a Hotpoint was that it also had a hot fill. Then I resubscribed to this ng and found Hotpoint was anything but the flavour of the month. :-(
