- Turn the dishwasher off and isolate power at the wall or breaker.
- Shut off the water supply if there is visible leaking or the machine keeps filling.
- Check the door seal, inlet hose, and the floor around the dishwasher for visible water.
- Do not restart the machine until the cause of the leak or overflow has been checked.
Gorenje uses f54 for a leak, overflow, or anti-flood protection event. The dishwasher has detected water where it should not be, or the fill level has exceeded the safe threshold.
- The machine stops and shows f54, sometimes with the drain pump running continuously.
- There may be water in the base tray or on the floor around the dishwasher.
- The dishwasher may refuse to start a new cycle until the fault clears.
- A real leak from a hose, seal, or internal water path.
- Oversudsing or overfill causing water to collect in the base.
- A sticking inlet valve or level control issue letting too much water enter.
- Residual water in the base tray triggering the anti-flood switch.
- Inspect the door seal for trapped debris or visible damage.
- Check the inlet hose and drain hose connections for drips or loose fittings.
- Consider whether too much detergent or the wrong detergent was used recently.
- If the dishwasher shows the same code again after drying out, the leak source or level-control fault still needs repair.
- Do not leave the dishwasher running unattended if it has already shown a leak or overflow code.
- Water and mains electricity are a risky combination, so isolate power before inspecting connections.
Book service if f54 returns after drying and the simple hose or seal checks, or immediately if there is an active leak, repeated flooding, or visible damage to valves, hoses, or seals.
