Broken dishwasher

[mylittlehouse]

Hello all
I have a Bosch classic dishwasher and over the last few weeks it's been making a racket when the pump runs.
As of last night it's not draining water but everything sounds ok pump sounds like its running etc
There are no error lights or codes on the machine.
What cai do to check everything before getting it repaired?
Thanks so much
