Take it we are discussing an intregrated washing machine? With a kitchen door to hide the appliance?
Where did you buy the intergrated door from?
I'm a kitchen designer and not a fitter so don't take this as gospal.

Just go into any major kitchen company and ask for "hob appliance door, for an intregrated extractor"
They are all standard sizes now a days. H394 x W600 x D18
However, in the past there was at least two different lenths. But to be sure just take the measurments.
Not sure what...
