What FF Means
Bertazzoni's own use & care manual lists FF as a water inlet system failure — the dishwasher isn't detecting adequate water entering the tub within the expected fill window, so the cycle can't begin normally.
Common Causes of FF
- Water supply valve behind the unit only partially open or shut off
- Debris or mineral sediment trapped in the inlet hose's mesh filter
- A failed water inlet valve or fill-sensing circuit
🔧 One Safe Check You Can Try
Confirm the water shutoff valve behind the dishwasher is turned fully open and the supply line isn't kinked, then disconnect the inlet hose from the tap and clean the small mesh filter inside the fitting — this is the exact first check Bertazzoni's own manual lists before contacting service.
⚠ Why You Shouldn't Go Further Than That
- If the valve and filter both check out, the inlet valve itself sits inside a pressurized line, and removing it without shutting off supply first can flood the cabinet underneath.
- This can look identical to a flow-sensor or float-switch fault, and replacing the wrong part based on a guess is a common, expensive mistake.
- Reaching the inlet valve typically means disconnecting water lines and partially sliding the unit out, which frequently voids any remaining warranty.
- A hose refitted even slightly loose after inspection is a common source of a slow leak that only shows up weeks later.
- Mineral scale that's narrowed the valve can be mistaken for a simple clog, and forcing it clear without the right tools can crack the valve housing.
