Fitting a dishwasher

[tigersaw]

Although I've survived over 40 years without one, I'm getting round to the idea that a dishwasher would be kinda cool.
I'm not afraid of a bit of plumbing, but need to know what a dishwasher requires. I'll get that sorted first, I presume a standard 15mm cold feed, and a 32mm waste pipe with a U bend like a washing machine?
Are there any condsiderations I need to make, like the waste has to be a certain height etc, special fittings/couplers required?

Its just the same as fitting a washing machine... just make sure it fits in the gap you have and that the waste pipe is nice and high with a U in it so you don't get any strange smells. Also its only cold water feed no hot (mine was), and that you have somewhere to plug it in... lol...

when you buy a dish washer it will come with every thing you need to plum it in and most fittings are now of the push fit type, you may need to have your exsiting plumbing changed if you dont have a spare water feed and waste under you sink. The machine should also come with a u bend piece that you wrap the waste pipe around and you just hang this in as high a position as possible to stop the waste water returning down the pipe to the machine.

hope this helps

All you have to do then is argue over who loads and empties it instead of who does the washing up!

It will come with a 15mm compression fiting for a cold water feed. I wouldn't bother running an additional cold feed, but just put a Y piece on the end of the existing cold feed - use a PVC Y-connector and some PTFE tape and you are well away. If the hoses the machine comes with are too short to reach, then go and get some longer ones, or connect 2 together (you should replace these every couple of years anyway).

Play your cards right and you can just alter where the washing machine drain joins the waste from the sink and take a second branch off it.

Do watch out for the power supply. It is not unusual to see kitches where people have run the washing machine and Dishwasher from the same socket. The D/W may draw 9Amp on the drying cycle. A tumble dryer, or washer dryer can draw an additional 7.5 Amp. Clearly 16 - 17 amp out of a single 13 Amp socket ain't a good idea.


You are likely to find that washing machines in the future will only take a cold water feed, and not a hot feed - it's some kind of industry standard thing going on

Its dead easy- i managed it. my dishwasher was also fine off the hot feed so i didn't bother with extra taps as the washing machine only comes off the cold

Thanks everyone.

The only place it can go is on the opposite side to the wash machine, so will need new plumbing, but that looks no probs.
Also, the countertops are all 55cm deep, seems most all dishwashers are quoted as 60cm deep, so I need to spend some valuable leisure time tramping round comets/currys/dixons/whatever with a tape measure..

As most dishwashers heat the cold water feed, you can save valuable pennies by plumbing in to the hot water. The water is unheated by rinse cycles, but will not be harmed by using hot water from your DHW.

u will find standard dishwashers are designed to fit in a gap 60cm x 60 cm unless you get a slimline unit, or an integrated unit which is designed to fit with a door over the unit to blend in with the kitchen.
