I have lost my manual for Teka DW640F1 dishwasher and im unsure how to put salt in, as i thought the salt was in the cleaning tablets i use but apparently i have to use salt aswell as i live in hard water area. Also as i no longer have the manual ive forgotten what all the symbols stand for.

Check the following when experiencing poor cleaning results:

- Dispenser (Where you put the Dishwasher Tablet or Powder)
Make sure that the flap holding the powder in is not loose.
Make sure it is dry before ever putting in powder.

- Dispenser (Flap Type)
To check if it is still opening for the Spray Arms (Spray Arms need to throw water on the Powdered contents to wash the dishes) - Put the Dishwasher in a cycle, and halfway through the cycle, open the door. if it has not opened then maybe the solenoid/actuator needs to be replaced.

- Program Selector (Not the component, the function selected)
More time consuming programs are more likely to wash more effectively, try selecting these with a higher heat setting instead of your usual programs like quick wash etc..

- Machine overloaded.
Make sure the baskets are not overloaded with dishes, mugs & glasses as this can make spray arms find it more difficult to clean between them

- Soap
In tests regarding powder vs. 3 in 1 tablets like "finish", it has been shown that powder gets dissolved much better, this is because the 3 in 1 tablets are designed to disintegrate on certain heating phases of only a select few brands of Dishwashers. So if you are unsure, or experiencing undissolved tablet - Use powdered dishwasher soap instead.

- Salt container
Refill the Salt container every 3 - 4 months depending on how frequent you use the dishwasher

- Spray arms
These can often be clogged with dirty water etc. clean these with toothpicks and pressured water.

- Filter
Clean these every time after a wash, usually found at the bottom of the dishwasher where water drains away.

- Over the counter products
These can be bought at Appliance spare outlets or even at some supermarkets. Use these as the directions indicate.

- Element (Last step if not improved)
Replacing a element is usually a last option, if no improvement was experienced by doing all of the above it could be that the element is not heating at the right temperature, or not heating at all.
Either replace this yourself (with various degrees of difficulty depending to the Make and model) or get a qualified service technician to do it with you.

Hope this helps :-)
