Bosch dishwasher (Saltdean BN2)

2 years old. Had been working fine but recently started making a noise when draining. Not attempted to fix it as we are having new kitchen put in with integrated dishwasher.
I think this is probably fixable if someone knows what they’re doing but we don’t have time.
Really was working totally fine and this came out of blue so probably something simple like a blockage somewhere.
