Whirlpool dishwasher badged as Diplomat ADP8322

Defective machine: the dishwasher runs for 10 minutes then pumps out. I noticed it ran an error message of a series of 4 beeps then a pause.

I'm told we need a new pcb but these are encoded by the manufacturers so that their own engineers have to be called to install
The part reference number I've been given is: Wpl.481221838615.

Can anyone help?

You don't need a pcb. Don't know who told you you did but it's 99%certain you don't need it.

4 flashes is a drainage failure.

Get a kettle, fill it and while it's boiling take out the fine filters in your machine.
Once it's boiled, pour it into the sump of the dishwasher getting as much as possible into the black grid in the sump.
Put the fine filters back, reset the machine and try it again.
If it still fails with 4 flashes you need to replace the water indicator (pressure switch).
