Before I pay huge sums of money for somebody else to fix it for me, is there anything I should be looking for?

When I start a cycle you can hear a hum/buzz, but no water is removed. The dishwasher will still clean dishes.

The outlet is attached to the sink outlet, this is clean. I've tried trickling some drain un-blocker down the discharge pipe to clear any blockage. Still no joy.

I have had Bosch dishwashers and every time you START a cycle it attempts to empty by pumping - just in case anything remains - I believe.

It would be pointless filling with clean water if something remained that OUGHT to be removed before the new cycle - that's my interpretation anyway.

If it fills & cleans after a minute let it continue.
