Float switch error; machine may continuously fill or will not fill and E14 is displayed.

Safety first: Disconnect power and allow hot water to cool. Be cautious when reaching into the tank.

• Locate and inspect float: Find the tank float assembly (often in a corner of the tank). Lift and lower it by hand to ensure free movement. Remove any debris or scale that may cause sticking.
• Clean float guide: If the float rides in a guide tube, descale and clean the tube so the float moves smoothly.
• Test float switch: With the float in the up and down positions, test continuity across the switch terminals. Replace the switch if it does not change state reliably.
• Check wiring: Inspect the harness from the float switch to the control board for damage or loose connectors.
• Reassemble and test: After cleaning and replacing parts, run a fill cycle and verify that the water stops at the correct level and E14 clears.
