Can anyone suggest what is wrong with my dishwasher. It's about 3 years old and this has only started happening in the last month or so. Things are not coming out clean, well specifically china mugs - go in tea stained and come out even more tea stained (in that it's an even darker brown). I have cleaned all the filters and sprayers, run a bottle of cleaner through it, plenty of salt and use Finish powerball. At the end everything is hot so it's not that. China used to come out as clean as new.
I'm flummoxed about which bit is not working. Any ideas. please?

It's worth trying a different detergent. Sainsbury's own brand "Prism" came out well in some recent tests, so we gave it a go and are very pleased with it (compared with Fairy and Finish which we usually use).

These are bone china mugs decorated with William Morris designs!
I always thought bone China was unsuitable for dishwashers ?

It sounds like your dishwasher might have issues with water hardness or detergent effectiveness. Despite cleaning the filters and using a cleaner, if the china mugs are coming out with more stains, consider the following:

Water Hardness: Ensure your water softener is functioning correctly. Hard water can leave deposits on dishes.

Detergent: Experiment with different detergents or increase the quantity slightly. Sometimes, what works well for one water type or dishwasher might not work well for another.

Rinse Aid: If you're not already using it, try adding rinse aid to help prevent spotting and filming.

Dishwasher Loading: Make sure the mugs are not obstructed and are placed in a way that allows water to circulate inside them.

Temperature: Even though you mentioned everything is hot, ensure the water temperature is high enough (around 60°C) for effective cleaning.

If these steps don't resolve the issue, it might be worth consulting a professional to check for any mechanical faults or water supply issues.
