De-scaler wont wash your dishes. The simplest cause of dishes coming out unclean is over-loading, bad stacking (spray arms blocked), or using too short a programme for heavily soiled dishes.

If it's just streaky (not food remnants), you may have the rinse-aid set too low. Open the flap where you add rinse-aid and you will see a know with an arrow shaped grip. There are 5 positions for the knob marked 1 to 5. Try a higher setting (1 is low) but don't go too high as this will cause other problems. If it's on 1, try 3 and if it's on 2 or 3, try 4 or 5. You may have to adjust this a couple of times until you get satisfactory results.

Howver, If you're referring to a white powdery residue on dishes and glasses, that's an entirely different answer . . .

Glasses etched and spotted in Thermador dishwasher soft water

I have spent a 50 year career in catering using dishwashers and seen all the damage that can cause. Etching is caused by using too much detergent. They tend to be based on Caustic Potash. Use as little as you can get away with. Rinse aids don't normally cause spotting, but having the water too hot can. If you are having problems, change the detergents and lower the temperature. You can also try Calgon water softener, but only a little. Also make sure filters are clean and run a liming solution through the machine once every 6 month. Before I retired, I was manager of a Toronto Airport business class lounge, and we washed thousands of plates and glasses a day 5:00am to 11:30pm. We descaled every week.

Dishwasher salt beko

Rinse aid and salt are not necessary if you use powder that is similar to the tablets. The lights are warning you that you havent added them, you know that so ignore the lights. If you live in a hard-water (limescale) area salt can be used as well as tablets or powder to make the water kinder to the machine, but most people just use tablets without rinse-aid or salt.

My dishwasher won't clean the dishes properly - very poor cleaning results with residue left on the dishes.

Hi,
Check The Salt-Level ? Dishwashers rely, On salt and cleaning Fluids/Rinse Aids et,c. Also check for Any Blockages or Obstructions/Kinks/Bends et,c. in The External Outlet/Waste pipe.

The dishwasher is not cleaning properly, glasses look like they have a film on them, plates also do not look clean & the dishwasher has a foul smell.. like rotting food in it.. we use the top quality...

Check the main drain system connected to the dish washer hose pipe. Clean the junction if clogged. This smell might orginate from the pipe.

Check incoming water quality. If hard water is noticed, use softener attachments to the inlet.

Fill dish washer salt in the dispenser. Refer user guide. The salt will help softening the water to certain extent. Finally check whether rinse aid dispenser filled with the rinse aid liquid.

Try cleaning the machine by adding white vinegar to the wash water (before the water-fill procedure finishes). Put your stained dishes and cutlery in with the wash to remove the hard water deposits. The combination of salt and rinse aid may have helped cause this problem. Hope this helps!

Dishes not clean

hi friend,HOW TO GET THE BEST FROM YOUR DISHWASHER
Always follow the manufacturer's instructions and read the directions carefully on detergent, rinse aid and salt packaging.
Cleaning your machine about once a month will remove any grease and lime scale deposits which can build up on the inside of the machine. Special dishwasher cleaning detergents are available which are used when the machine is empty. These cleaners will often leave a fresh smell in the dishwasher too. If you want to have that fresh smell all the time, use a dishwasher freshener. These are usually supplied as hanging tags, which should be carefully positioned away from any moving arms. A freshener is essential if you load during the day and then run the machine at night.

These items can be washed in a dishwasher, with the following guidelines:
Glassware - Any ordinary glassware and ovenware such as Pyrex. Do not wash lead crystal glasses unless they carry a "dishwasher safe" label.
Tableware - Most everyday crockery is safe. Bone china usually has under-glaze decoration and should be safe. Avoid antique or hand-painted and over-glaze decorated items. If in doubt, check with the manufacturer.
Cutlery - Stainless steel and silver cutlery are normally suitable for machine washing, but it pays to rinse off any acidic food before loading to prevent any corrosion and, if possible remove the cutlery immediately after the cycle, to avoid prolonged exposure in a humid atmosphere. Do not mix steel and silver cutlery in the same basket and wash bone or wooden-handled items by hand.
Plastics - Check whether they are dishwasher safe and do not place in the lower rack, where the heating element may affect the plastic during drying.
Pans - Stainless steel is ideal for dishwashers. aluminium can be washed in the machine, but may discolour during the rinsing. If in doubt, remove aluminium pans before the rinse cycle.
Always wash cast iron and wooden handled items by hand

WHY DOES MY MACHINE HAVE A WATER SOFTENER?
If the water is soft (i.e. does not contain calcium particles), the detergent will work more effectively and there will be less streaking on dishes. Hard water can also block the washer jets with lime scale and cause deposits on heating elements, which will reduce the cleaning efficiency, increase electricity costs and shorten the life of the machine. All dishwasher manufacturers (Bosch, Miele, Siemens) and detergent suppliers want you to get the best results from the machine - and soft water is one of the most important factors in achieving this. The way to ensure water remains soft is to regularly top up the reservoir with granular salt.
Three in one salt tablets do not activate the water softener.
HOW MUCH SALT DO I NEED TO ADD?
Your machine may have a float indicator or a warning light to tell you when salt needs adding to the water softener. Often float indicators are difficult to see, and there is no accurate guide as to how much salt you need to add. Quite simply, just add granular salt to the reservoir until it won't take any more!

The softener will use the salt to replenish itself each time you wash. As an approximate guide, you should do a full top up about once a month. If your machine doesn't have a warning light, a good way to remember to check and / or top up is to do it on a regular day of the month (e.g. the first Saturday or the 15th)
CAN I USE ORDINARY TABLE SALT?
No. Table, cooking, rock and sea salts may contain additives that can actually increase water hardness. Also, the fine consistency of some of these salts mean they are likely to clog when wet. Always use granular dishwasher salt because it is very pure and is the right consistency for use in your machine.
Granular salt is the ONLY type of salt that should be used to regenerate the softener. Be aware that some varieties of ‘dishwasher salt’ use Dead Sea salt. This variety may contain minute insoluble organic matter that may adversely affect the resin within your softener over time. If you are in doubt about the origins of the salt, ask the retailer or manufacturer.
WHAT DETERGENT SHOULD I USE?
All modern dishwasher detergents are formulated to work specifically in dishwashers. On no occasion should ordinary washing up liquid be used, as it will cause excess foam, which can result in a leak. If it is accidentally used, sprinkle ordinary salt into the chamber to disperse the resulting suds. Then rinse away the excess salt before using.
There are 3 main types of dishwasher detergent - Powder, liquid or gel and tablets. Which one you choose will be down to personal preference, but most people find tablets very convenient, although using powder is usually more economical and liquids are less abrasive on more delicate items.
WHAT IS RINSE AID?
Rinse Aid is added to a special compartment in the machine and a very small amount is released during the final hot rinse cycle, to reduce the formation of water droplets on crockery etc and so ensures that the water dries away properly and evenly to avoid leaving smears.
Dual action detergent usually contains rinse aid, which is released at a different rate to the cleaning agent and so helps reduce smearing etc without the need to add separate rinse aid. Some 3-in-1 tablets contain an ingredient, which has a 'salt action', which also helps to improve cleaning, but NOTE this is not a substitute for adding salt to the water softener.

The salt action takes place in the cleaning chamber of the machine, but does not actually replenish the water softener. Research has shown that whilst 3-in-1 detergents do clean dishes effectively, their performance is improved by adding salt to the water softener reservoir.
As the performance of machines can vary, as can local water conditions, it is always best to follow your manufacturer’s advice. Some manufacturers advise that if you have unsatisfactory cleaning performance eg white powder residue, poor drying or dirty dishes, then you should return to using three separate products ie detergent, rinse aid and granular salt. Be aware that if you have not been filling the salt reservoir and relying on the salt in 3-in-1 tablets, then it may take a few cycles to re-generate the softener.
