1. Is there a right way to load my dishwasher?

When it comes to loading your dishwasher, there is a proper way to load your dishwasher to ensure that you get both amazing results and protection for your dishware, cookware, flatware and glasses. As always, you should always follow your manufacturer's recommendations when loading your dishwasher, but here are a few simple guidelines to follow:

  • Before you put anything in the dishwasher, scrape off the large food particles and do not pre-rinse. Your dishwasher detergent’s job is to cling to food and help wash it away.
  • With cutlery, make sure to avoid nesting so that water can rinse all surfaces.  Since safety comes first, long/sharp knives should face downwards. With spoons and forks, mix it up!
  • Load your large soiled dishes on the bottom rack of the dishwasher so they get good water flow. Be sure to load stemware and cups on an angle so water can run off the bottoms and dry properly. Always face stains towards the spray arms, and as long as pots and pans are dishwasher safe, they can be cleaned.
  • If your dishwasher has an exposed heating element, plastics go in the top rack, but if it has a concealed heating element, plastics can go anywhere in the dishwasher. But be sure your plastic is dishwasher safe!

2. Dishwasher or Sink: Which uses more water and energy?

With energy bills going through the roof in recent years, consumers are rightly looking for ways to economise. Some are obvious such as turning off lights when not in use. However, one measure that could surprise many is to use a dishwasher to wash up.

Leaders in dishwashing Bosch and Finish have joined forces and calculated that the cost to run a dishwasher can be only 37 pence on average, including detergent, water and electricity. In fact:

-          The energy cost for running a full dishwasher cycle is only 14pence, the water is 3p and detergent products make up the rest

-          A typical half hour of ironing uses MORE energy than a dishwasher cycle (Source Eureko)

So how is this efficiency possible? 

When washing up by hand we need hot water, changing it on large loads to get any kind of clean result. Doing this several times a day can make the energy useage really add up.

A dishwasher on the other hand uses and heats only the exact amount of water needed, cleaning and re-circulating on average 12 litres of water for a 12 place setting.  In fact, its like 4000 litres of water being re-circulated around the dishwasher’s spray arms. Combined with powerful detergent the modern dishwasher gets everything clean without being an expensive luxury.

So next time you think about how to reduce those energy and water bills, make sure you keep using the dishwasher!


Calculate your savings!

Extensive studies have been undertaken by Bonn University comparing the water and energy consumption, cleaning performance and also time spent to wash a full dishwasher load by hand vs in the machine.  The full results and an interactive comparison calculator are here

3. How can I reduce energy and water use?

A dishwasher uses typically 1.2kwH of energy per wash, about the same as half an hour of ironing. It also uses just 14litres of water, about a bowlful, with some using as little as 6litres! To minimise energy and water use, follow these tips:

- Use 50°C, ECO or AUTO as your every day program.
- Do not pre-rinse dishes by hand, it’s not needed and only wastes water.
- Always run a fully loaded dishwasher.
- Check and clean drains and filters regularly to ensure efficient operation.
- Recycle product packaging.

4. How can I get best cleaning results?

  • Avoid low quality and old/damp detergent.
  • Use the detergent brand recommended by your manufacturer.
  • Always place tablets in the dosing chamber.
  • Load and sort dishes to allow wash water to circulate and run off freely.
  • A cleaner dishwasher means cleaner dishes. Use Finish Dishwasher Cleaner to clear build-up of grease and limescale.
  • Load dishes correctly so wash water runs off freely.
  • Regularly add Finish Shine and Dry rinse aid to the rinse aid dispenser.
  • Add Finish Salt if you live in an area with extremely hard water.
  • To maintain performance of your machine, remove and clean filters regularly.

5. How can I stop my glasses clouding?

  • In hard water areas, avoid limescale deposits by adding Finish Salt into the salt chamber.
  • Determine your local water hardness and adjust the machine setting accordingly.
  • Such limescale clouding can be removed by cleaning with white vinegar.
  • White streaks on glasses could be surface corrosion. Unfortunately this is irreversible but can be avoided by using low temperature, glass cycles or using dishwasher proof glassware.

6. What detergent should I use?

For best results use the detergent recommended by the manufacturer of your machine.

Most put their name to Finish Quantum which is our most advanced formula containing 9 powerful cleaning actions including salt and rinse function.

In very hard water aeas we also recommend the use of seperate Salt and Rinse aid to protect your machine and achieve the best result. 

7. Do I need to add salt and rinse aid?

Rinse aid is required to

  • Ensure spot-free, shiny dishes
  • Assist the drying function

Salt is required to

  • protect your machine from limescale
  • soften the water for better cleaning

With multi-benefit tablets such as Finish Quantum and Finish All in One, rinse aid and salt functions are included. However, in very hard water areas we also recommend the use of seperate Salt and Rinse aid products to protect your machine and achieve the best result. 

8. What does Finish Dishwasher Cleaner actually do?

  • Remove limescale and grease that can build up in your dishwasher over time
  • Eliminate odor caused by build up in your dishwasher’s filter and freshen your machine
  • Maintain the mechanical power of the sprayer arm
  • the machine reach the optimal heating temperature
