All-in-one tablets clean and rinse your dishes in one cycle, with one tablet.
Like living in a soft water area, using an all-in-one tablet will help reduce the usage of your dishwasher salt, but you should still ensure your machine has some.
If you’ve noticed any issues with your dishwasher not performing at its best, it might be time to get it checked over by a qualified engineer to fix your dishwasher.
