Midea Dishwasher Error Code E4
Overflow — excess water detected
Common Causes
- 1Fill valve stuck open
- 2Leak into the base tray tripped the float
- 3Float switch stuck up
- 4Sump seal leaking
Standing water around the base electronics is a shock hazard. Kill 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 right away
- 2
Check whether water keeps entering with power off — that means the fill valve is stuck open
- 3
Slide the unit out and inspect the base tray for standing water from a sump or seal leak
- 4
Dry the base tray and confirm the anti-flood float moves freely and settles down
- 5
Fix the leak or replace the stuck valve, then verify the float has reset before powering up
Pro Diagnostic Tip
E4 stays latched until the base tray is dry and the float drops. Wiping only the tub leaves hidden water under it, so the code returns instantly on restart.
