Bosch SGS56A72GB/17 aquastop.

I picked up a limited edition Bosch dishwasher last week and it worked perfectly for a few washes then stopped working altogether.
Symptoms:
The drain pump works continuously even when the door is open.
The machine is not filling unless it is rocked then it works fine.
I emptied the machine by hand and that stopped the drain pump running.
I removed the cover from the impellor and the motor did the right thing and is not blocked.
I then took off the LHS cover and found crud in 2 places as shown in the pictures below.
I also found some water in the bottom tray of the machine and since it has the Aquastop feature, I figured this was causing it not to fill….
Are there any common areas for these machine to leak?
Is it worth removing the plastic tanks at the side to clean them or not?

I found out that the O rings at the bottom of the reservoirs have leaked, causing the pool of water in the base of the machine, trriggering the leak detector and stopping it working.
I removed the reservoirs and cleaned the crud out and reseated the O rings – no leaks now, machine seems to work fine, except it’s not draining properly now.
Is there a ‘total reset’ for this machine?

If it’s not draining properly now then you will have a mechanical blockage somewhere…if you’ve had the impellor cover off and thats ok then I would start at the sink end of the drain hose and work back 😉

Problem solved, I had srewed the Impeller cover on crookedly.
