Dishwashers

Just a thought , have you checked the filter and the outlet hose to make sure they're not full of gunk as if they haven't pumped out properly they don't take on more water.

No advice on a new one I'm afraid, mine is older that yours 

Definitely follow up on Lardy's suggestion.

My advice on new dishwashers: don't, if you can avoid it. This may not apply to Bosch, but many of the American-branded ones (Whirlpool, Maytag, Amana, Frigidaire, etc., EXCEPT General Electric) the inner workings are all made by the same manufacturer. There is a common part in them made of plastic, it warps over time due to dishwasher temperature, then the machine leaks. The plastic part is not available at any cost, boom, you need a new dishwasher.  This was information provided to me by an appliance repair man that services those American brands, he is highly trusted in our area.

We currently have a G.E., it's OK, not fantastic.

If there's a repair man you trust, I suggest you ask if your Bosch is repairable. Unless of course you don't care for it and want a new one.

Top cutlery tray is great.
As for makes we've currently got a Samsung not cheap, but we’re on our 3rd because we’ve had issues with the first 2  but they just replace them. Hubby thinks this is a good deal, I’m not so sure, but 5 years in & we’ve still got an under 1yrold machine, plus they give an extended 5 yr guarantee as standard

We bought a Bosch after numerous Indesit dishwashers.
So far so good after 6 years. The Bosch cost more than our Indesits did but hopefully will be more reliable. Works well if loaded as required with salt etc.

Our dishwasher is a 'Growster', and I'm told is always reliable...

I'd say 'usually' reliable, but as I always do the job, I suppose I'll have to agree!

Mine is bosch, probably about 23/24 years old. never do the filter. having cutley tray which is carriable is good and inside fold flat, so great for cleaning oven shelves.
