Calling PigletJohn - Dishwasher woes

[kippersmum]

My Bosch dishwasher isn't cleaning properly. I have cleaned out all filters, spray arms etc etc. It is the bottom right hand corner that isn't getting stuff clean, especially pans.

I think the arm is turning OK. All the top layer stuff gets washed fine. I've googled stuff but nothing seems to help.

So I'm doing the MN tried & tested approach, when nothing else helps ask PigletJohn for advice :)

TIA

Run it empty, open the door a few times and look to see if the arm really is spinning, and if it is getting fully hot, and that the tablet falls out when the hatch opens.

Take the basket out to see if there is anything sticking out that could obstruct it.

How did you clean the arms?
