I have an industrial size Daikin AC unit installed in my villa in Marbella. To cut a long story short the construction company who built my villa didn't pay Daikin for the unit. Daikin Spain are refusing to fix my unit under warranty because of this but I am left with no AC in my house despite paying all the bills to the construction company.

The unit is displaying the fault code FL and I am told it needs a new flow switch which Daikin Spain will not supply under warranty but Daikin UK can supply through a wholesaler.

The model number I have is EUWYB16KAZW1
The part number I believe I need is 510023P with a S10L wiring diagram.

Can anybody tell me where I can source these parts in the UK?
