Dishwashers, actually saves water. Electricity usage is another matter. For the 12-15l used by a dish washer for the a full load, unless you installed the handy foot activated tapmaster (www.tapmasterinc.ca/residential), water consumption is on average 6 times more. The only alternative is to have a bowl sink filled with water. One with soap and one without. Wash grime off one bowl. Rinse in the other. This is Euro/Oz style manual dishwashing.

The only thing that's be aware of is placement and plumbing. The extra piping for inlet and the plumibing for outlet. As far as I know, Ikea Atlant bowl drains has dishwasher/front-loader washing machine drain spigot that allows water to drain out from the sink. Teka sinks also has them. I would suppose some of the Euro sinks will come with dishwasher/washing machine spigot to allow water to drain.

Also some models like Teka or German made Bosch uses Euro type plug. So need to change to British type 3-pin or use one of those Wonpro type adapters.

I nearly installed it once in condo. Planned the kitchen deliberately with a dishwasher in mind. Had contractor drill 2 holes on the left of the sink cabinet frame to allow for inlet/outlet and electrical socket located under sink drain (a 13A plug outlet from study was co-incidentally located directly behind the left-bottom of the sink cabinet). Cabinet has to be of the height that can take a stand-alone dishwasher ie about 85-86cm assuming that their top cannot be removed (81-82cm if possible).

Due to not knowing where to find a drain spigot, I was planning to install a Kleenguard or Insinkerator underneath the sink which has a dishwasher outlet adaptor built-in. Expensive yes but some things to think through without hacking too much in condos. Now at least I know where to look. Ikea Atlant trap/water trap (used to be RM55 way back) for all their sinks comes with two spigots so that you can have dishwasher and washing machine on either side of the sink. No need to get Ikea sink, just make sure the sink outlet is of the same diameter (90mm) so planning is involved. See image 10 of the Atlant instruction http://www.ikeafans.com/forums/ikea-instru...-annotated.html.

Disclaimer: it may not fit all sinks even though there's a Atlant double bowl trap. Chances are if adding a dishwasher is an after thought, it's better off near next to the washing machine outside in the drying area or you have decided to renovate the kitchen.

Ideally, if the kitchen is galley style like in a train ie 2 straight 'I's, the washing side can be higher from the cooking side (lower) opposite. Too high cabinetry does not suit most of us cos wok would be too high.

I still bought a Teka LP800 dishwasher. Moving to landed and planning the kitchen the same way, I had an 13A outlet brought behind the dishwasher. Plumbing was just a hack to have the outlet 40cm above the floor behind the dishwasher and a T brach off from the cold supply of the sink running out behind it as a washing machine/bidet type bib.

One more thing, when opening the dishwasher after drying is completed, some steam will come out. To prevent it from ruining the underside of you cabinetry, buy one of those Japanese rigid alumimum foil heat conserver made for hobs. Keep the magnet for something else but place that over the dishwasher top. It should fit like judge's wig. Once you open just after, pull it out. It will guide the steam away from the underside of the cabinet and into the open air. Just my 2sen.

Ya, for our use, it's mostly higher than usual. Usually free standing dishwashers are 85-86cm with top cover. Some can have it removed that it becomes 81-82cm. Integrated could be up to 81-82 in height. The height I left my sink area is 86cm so it can generally fit any dishwasher with their top intact.

This problem may not apply for those with wet and dry kitchens but rather for us who have them both integrated.

In a single wet/dry kitchen, the cooking and food preparation side is lower which is only possible in a galley style (2 parallel 'I' like in a train).

For C, G and U shaped layouts, segregation is needed with a break in height of the counter tops for washing zone from ccoking and food prepration zones. This can easily be achieved with artificial stone tops. If using concrete/tiles, marble stone, mdf board, a fridge or storage cabinet can establish a break between zones where permissible.

For an L shaped kitchen, as long as the cooking zone is on the separate L leg segment (very far away) from the washing zone, the only choice is to use aritificial stone to drop the height for cooking. Otherwise, countertop height is uniform throughout which may not suit some of us since the wok sit higher. Chopping onion and garlic would be too high for comfort also.

For existing kitchen, the next best place for the dishwasher is beside the washing machine usually outside if space allows.

For apartments with limited balcony space, some designed their kitchen to have dishwasher and washing machine on either side of the sink. The only solution I discovered without investing in an Insinkerator/Kleengard is either an Ikea Atlant sink trap or a Teka sink which usually includes a trap which has a dishwasher adapter. This solves the waste outlet issue. Tee off from the cold supply is also minor work. The only challenge is locating the 13A. So this one must be thought out from the beginning.

Here's how to DIY guide your plumber and kitchen installer if renovating.

Usage in combi with a waste disposer like Insinkerator or Kleenguard. Some maintain that an airgap here and here and here is needed in combination with dishwasher use.

Dishwasher tablets or powder
Rinse aid liquid
Salt is not required. Set the water hardness scale to the minimum. Our water here is soft.
Try Henkel's Somat tablet and rinse aid.

Proper placement of dishes, cups, cutlery and utensils are crucial. Cutlery especially need to be spaced out. The cutlery basket caddy without the space guide grille needs careful distribution such that forks and spoons don't clump together preventing reach of detergent and water.

In the past, it is true that dishwashers don't wash out stains much less stubborn stains very well for a very simple reason...the hot water is not hot enough. Today, hard stubborn stains can be removed even if left overnight if the dishwasher's intensive wash program temperature is at least 70°C. Of course, it's better to scrape off the excess.

When getting a dishwasher, ensure its highest temp meets the above criteria for the intensive wash program. Anything less leaves the dishwasher wanting in its purpose.

The other thing is the dishwasher powder/tablets and rinsing aid liquid. Some have it combined in one tablet. Commonly it's separately wash tablet and rinse aid liquid. Try different brands. So far, Henkel's Somat works very well.

As with washing machines or hot water storage heaters, filter out sediments at point of entry down to no larger than 1 micron to ensure sediments don't clog the water intake inlet which has a sediment screen like front load washing machines. Otherwise, excess sediments might play havoc with the spray pattern.
