Ive got a Bosch dishwasher, and while its better than some machines I've had, it does have a very annoying habbit of sometimes leaving what can only be discribed as a food residue based grid on stuff, often as a splash across items, it seems to be that when its splashing water around and re-using it, its hanging onto it just a little too long instead of pumping it away and starting with fresh. Rinise aid is topped up as is salt and I use finish all in one dishwasher tablets. The issue can occur regardless of if I've given the filter in the bottom a good clean and if I've recently run one of those dishwasher cleaning cartridges with through.

I'm thinking there must be some sort of sensor that detects how dirty the water in the holding tank is... maybe a light based sensor.... I was thinking, can I somehow hobble this, so it thinks the water is dirtier than it is, so it renews it more often. Yes it'll make it a bit less green in turns of water and energy use, but its not very energy efficient to have to put half the load through again when it happens

Any one got any thoughts on this? or if I've missed anything obvious?

I think you probably have got something too big in your dishwasher and its hitting the spray arm under the top rack, or something is poking through the bottom rack and stopping the spray arm from spinning.

I have a bosch and had the same problem until I found my plates were too big when combined with wine glasses on the top rack (have to lower the top rack for wine glasses).

Yup you gotta check the thing will freely spin round before putting it on.
 
In addition to my previous post.
Check you have actually put dishwasher salt in there.

We use the 2 in 1 dishwasher biscuits - detergent and rinsa aid.

Stop using the eco wash cycle.

Let me know what happens.
 
I find our Samsung dishwasher struggles with chilli con carne and sprays it up on to the glasses leaving a skid mark. Everything is stacked correctly and free to move, it just seems to be a quirk.

So when we have that dish I scrape as much off as I can and give it a rinse.
 
Just thought of another thing.

Clean the dishwasher.
Remove and clean the spinnering bits, empty the catch basket and use a dishwasher cleaning thing from the supermarket.

Periodic preventative maintenance will keep it in working order.
 
Do you clean the filter between each cycle? If i don't rinse out the mesh filter thing in the base every time i get dirty gritty marks over stuff, also avoid the eco cycle as that seems really bad for it, i think mine only uses something like 9 litres of water on the eco cycle so it obviously gets heavily reused which doesn't lead to very good cleaning.

That seems a bit excessive. Maybe you have items blocking the spray arms too. I clean my filter maybe once a month, sometimes every 2 months. I also only use the eco cycle on my bosch.
 
I used to have a Bosch. Almost never cleaned the filter (6 monthly maybe), never used salt, always used the el cheapo Aldi all in one tabs, always ran in eco mode... and only got the gritty residue if I blocked the arms.

Same story now with the Beko I replaced it with when the Bosch died.
 
We use one of those finish in-cycle wash packs in an empty high temp cycle. Works really well, and leaves it sparkly again.

The wife gets some SUN brand dishwasher tablets from France in a big pack when we're over there. Way cheaper than the UK packs.
 
Another vote for a restricted or blocked arm.

It's either being stopped by a dish or utensil, or one or two of the ports are blocked.
 
I have always found three sources of bits
Blocked/restricted arm/filter
An upturned item thats catching and later releasing bits, something light typically that gets flipped over in the wash
Something thats particularly tricky to clean, so maybe a baking tray or something like that. It holds on to its bits way later into the wash and then can mean they are still in the water at the end
