Common Causes
- 1Leak into the base tray tripped the float
- 2Fill valve stuck open
- 3Sump or hose-clamp leak
- 4Float switch stuck up
Base water sits next to the electronics — shut power at the breaker before pulling the unit out or drying the tray.
Step-by-Step Troubleshooting
- 1
Unplug the dishwasher and close the supply tap
- 2
Slide the unit out and check the base tray for standing water
- 3
Dry the tray and trace the leak at the sump gasket, hose clamps, and door seal
- 4
Confirm the anti-flood float moves freely and drops when the tray is dry
- 5
Repair the leak and verify the float resets before restoring power
Pro Diagnostic Tip
E4 latches on the base float and only clears once the hidden tray water is gone. Drying the visible tub is not enough — the water sits under the tub liner.
