Classeq dishwasher displays E10; machine may not start and base tray may contain water.

Safety first: Disconnect power and close the water supply immediately to prevent further flooding.

• Inspect base tray: Remove the front kick panel or side panel to access the base tray. If water is present, carefully sponge or vacuum it out.
• Check anti‑flood float switch: Locate the float switch in the base tray. Ensure it moves freely and is not stuck in the raised position. Clean any grease or debris. Test continuity with a multimeter while moving the float.
• Identify leak source: With the tray dry, briefly restore water and run a short fill while observing the machine with panels removed. Look for drips from the door gasket, tank seams, hoses, pumps, or boiler connections.
• Tighten or replace components: Tighten hose clamps, replace cracked hoses, and renew perished O‑rings or gaskets. If a pump seal is leaking, replace the affected pump or mechanical seal kit.
• Reset and test: Once the leak is fixed and the float switch is reset (down position), clear any stored error (if applicable) and run several test cycles while monitoring for further leaks.
