Dishwasher crud!

Using a dishwasher is definitely proven to be more economical and more hygienic than washing up in a bowl or sink. (The cruddy deposit is obviously dishwasher clean!) I use Fairy 3 in 1 pouches, always look for the offers in Morrisons and compare unit prices. Our water is middling hard so I fill the salt and rinse aid too. There's never much food residue on our plates. We're northerners! We lick them clean! ? (Joking!!!!)

Is there crud in the door seals?

In my soft water area I don't need rinse aid or salt but am very careful about rinsing. I found tablets didn't fully dissolve in my old machine but my new one copes well. No need for more expensive gel ones but aldi 3in 1 work perfectly. No residue or Vom!

We are in a hard water area and had the same as you despite salt and rinse aid. Since starting using F---y platinum everything is sparling. Expensive but worth it.

Like many posters here, I rinse the worst of the residue off before putting dishes in the dishwasher. To be honest, I never put glasses in the dishwasher now, as they eventually end up with a cloudy appearance which doesn’t come off, (due to tiny scratches, I believe).

You need to rinse plates before putting in dishwasher. I use Aldi tablets no problem. Have softened water so no salt, If you wash glass at too high a temperature they can go cloudy which can’t be rectified. So maybe rinse the plates then wash at low temperature.

Same here. I use Ecover classic tablets which do not have salt or rinse aid (never used either over the nearly 40 years we have had dishwashers). I do clean food residue off plates though by scraping them into the compost or food waste bucket and don't put cutlery with caked-on food in before soaking it.

I stopped using salt and rinse aid as my engineer said the water here is soft so we didn't need it . I never have deposits on my dishes after the cycle

The only time I had the problem was when I tried supermarket tablets the problem cleared up when I went back to my usual 3 in 1 Finish tablets. Maybe that’s your problem?

I've never had any residue left on dishes after washing cycle is finished.
I've never used a dishwasher cleaner either. All I ever do is rinse off anything lumpy on the plates before I load the dishwasher. I use the 3 in 1 tablets.
I'm sorry that I've no answers about the crux on the cups and glasses.

I don't get dishwasher crud and never have done in any dishwasher ever owned. I use pods and don't use salt or rinse aid ever and very rarely use the cleaner. Then again I ensure the stuff put in isn't covered in crud either which simply involves a quick rinse under the tap. I certainly don't wash them but potato masher wouldn't be full of potato either as it's notorious for clinging to everything.

It won't be cheaper to wash up by hand.

Scraping the plates well seems like the way to go.

Mine does that too. Mashed potato residue left on plates is particularly bad for coating everything in the machine. A quick rinse under the tap for things with "stuff" left on them, before putting them into the dishwasher, has stopped it most of the time, and cleaning the filter helps too. I think some makes are worse than others.

Sounds like hand washing would be alot quicker, easier , thorough ohh & possibly cheaper ?
