symptoms of no dishwasher salt

[abcdabcd]

I haven't used salt as been using 3 in 1. However, my dishwasher is making odd noises (like a crackling). Is this as a result of limescale build up and if so, what can I do???

i cannot solve your problem but the consumers association says you must use salt even though you use 3 in 1

you can get a rinse to put in and run when empty that cleans it out. Tesco do them.

None of the dishwasher products that claim you need not use salt are actually worth using, most especially in a hard water area. I stick to the old style classic tablets (when I can find them) and always add salt.

I dont know what the noise is, but I haven't ever used salt in my dishwasher in the last 10 years and never yet had a problem.
