Hi, well this Beeping, simply indicates a "Fault" however it gives NO indication of what? It maybe a sensor, the main board, the motor? but it could be many many things unfortunately. What you need to do is either DIY troubleshoot or call a professional, it is really that simple.

above is a DIY help website to assist you in troubleshooting, use the manual to isolate and hopefully repair your unit.
However if you don't wish to DIY the to get the best and cheapest outcome, is to contact an F&P local or head office, and ask for a referral to an authorised service center, now when in contact here ask for a service call, however ONLY ask for a "Quote" as to costings, now when you are appraised of these then one can make up ones mind as to what to do, repair or replace?
