Where to refill rinse aid?
Your dishwasher will tell you when it is running low and needs refilling. You will also notice if your dishes are not as shiny after the last rinse. Most dishwashers will have an indicator light. The reservoir is always on the inside of the door, next to the compartment that holds the detergent. Do not confuse it with where you refill the salt, which is always at the bottom.
What amount of rinse aid will ensure that no stains are left behind?
You do not need to worry about overfilling with rinse aid. Every dishwasher has a mechanism that regulates the amount of rinse aid needed each time you wash.
If your dishes still have spots and streaks on them you can choose to adjust the settings.
If your dishes do not dry well, you can choose to adjust the dosage. You can increase the dosage if your dishes do not dry properly and decrease it if there is a sticky residue.
Is separate rinse aid better than an all-in-one dishwasher tablet?
If you use an all-in-one dishwasher tablet with rinse aid, there is basically no need to add rinse aid. If you are having trouble getting the best results, it is a good idea to add detergent, salt and rinse aid separately, as this allows for better metering. This way you can be sure you are using enough detergent even for a small wash with few dishes.
The amount of rinse aid a dishwasher uses
How much rinse aid a dishwasher uses varies by type. With average use, which equates to one dishwash per day, you should refill the rinse aid once every three months. You can go as crazy as you want with this. There are half-litre bottles of rinse aid available for less than £1, but some premium brands will charge up to £5 for the same amount.
Check out whether using an all-in-one dishwasher detergent can make a difference. In some cases, this can be cheaper than using separate detergent, salt and rinse aid.
