I have Bosch dishwasher, I used to use the all in one tabs but just switched to separate rinse aid, salt and dishwasher powder (cheaper!).
Trouble is, it doesn't say on the dishwasher instructions or the salt bag how much to put in.
Do you know much I should put in? Can I put the whole bag in (if it will take that much) and just top up when the salt light comes on? It has a screw lid at the bottom of the machine and I have filled it with water as per dishwasher instructions and just put a couple of cups in for now (and the light has gone off). Obv don't want to put too much in but also don't want to have to keep topping up often if I can just put the whole lot in.
i just fill mine until i can't fit any more in. the instruction manual should tell you how much will fit, but if you don't have it to hand then just chuck as much as you can in. be careful it doesn't all overflow though
I remember reading something ridiculously complicated in a dishwasher manual.
It was something like - phone up your local water board and ask for the <something to do with water softness figure> then multiply it by something else in this helpful table we have put in the manual, then add your shoe size and the number of times you blink per hour to get the number which determines how much salt you put in.
i dont bother with the salt i filled mine to the top when i first got it and the light was still on i filled it again a few weeks later and still not gone off so with that i just did not bother any more and my dishes still come out as clean and i have never had to have it fixed touch wood and its 4 years old
