Error Code AE

Leakage Error — internal water leak detected by float/safety switch in base

Moderate

Address soon - your appliance may not work properly

What This Means

Door gasket came loose or fell off; Float assembly (safety switch) stuck; Controller (main PCB) damaged; Seal assembly on sump not properly connected; Unit not leveled correctly; Wrong detergent used (non-dishwasher detergent causing sudsing); Door opened during cycle

How to Fix

1
Check if water is flooded in the base; if yes, tilt machine and drain water from base
2
After draining, inspect drain hose sealing, pump casing assembly, and vario motor for source of leak

If leak source found, reassemble or replace the leaking part
4
Check if safety switch assembly is stuck; if yes, replace safety switch assembly
5
Check if door gasket came loose or fell off; if yes, replace door liner assembly
6

8
Confirm door was not opened during cycle
9
Check if there is too much water in tub (overfill); if yes, replace inlet valve or air guide
10
If float switch stuck in triggered position with no water in base, replace main PCB assembly
11
For AE report: document unit level, mounting bracket condition, detergent type, cycle history, water supply temperature, and whether door was opened
