F3 is a pump system failure.
most likely cause is a pump transistor T1P or T2P failure.
Now in the possible causes section of the problem diagnosis section it gives more detailed explanations:
"Shorted T1P, T2P (T3P if equipped); Open wiring; Driver board defect; Logics defect; Open circuit pump motor or PA1, PS2 cables; Welded pump contactor (if equipped). Shorted Z321 or Z322 (if equipped)."

you will need the diagram schematic that is usually located underneath the hood that has the diagram of the electrical system with labeled components and a condensed troubleshooting and onboard self check chart for self diagnosis and/or the service 'troubleshooting' section of the manual, some tools to remove the components for testing and a vom meter, (and a handyman tester if you need to gate or leak test any transistors).

In most cases these issues wind up being a bad T1P or T2P transistor or a welded contactor (if equipped). The transistors should be disconnected before checking.

Funerals in Spain typically occur within 24 to 48 hours of death, whereas in other European countries they wait one or more weeks. This rapid timeframe is a cultural norm grown from the past need to manage the warm climate without modern embalming.
