E4 error code
Which appliance is showing it?
E4 can mean a water or door problem, a defrost fault or overheating, depending on what's showing it.
What E4 means on each appliance
The short version for each one, and the first things to check. The full guide has every step.
On a dishwasher: water supply or door latch
Depending on the brand, E4 means low water supply or a door latch problem, so it's worth checking both.
Check first: Check the water; check the door latch.
On a fridge or freezer: defrost sensor failure
The fridge can't run its defrost cycle properly, so ice builds up.
Check first: Defrost it by hand; test the defrost sensor.
On an air fryer: overheated and cut out
The over-temperature cut-out has tripped: the fryer got hotter than it's allowed to, and shut itself down to stay safe.
Check first: Let it cool right down; clean out the grease; give it space.
On a brand-name appliance?
Big brands use their own codes for the same faults. If your appliance is one of these, its own page is more precise.
- Frigidaire washing machines use E4 for their own code: E4 out of balance during the spin.
- Some Samsung washing machines show E4 instead of UE: unbalanced load.
- Some Mitsubishi heat pumps show E4 instead of E0-E5: remote controller communication fault.
- Dishwasher: Samsung 4C LG IE GE H2O Frigidaire i10
- Fridge or freezer: Samsung 5E LG Er dH

It depends on the appliance showing it: on a dishwasher, water supply or door latch; on a fridge or freezer, defrost sensor failure; on an air fryer, overheated and cut out. Each appliance's page has the checks in order.

Often, yes. How hard it is depends on the appliance (dishwasher: very easy, worth fixing; fridge or freezer: moderate, worth fixing; air fryer: very easy, usually free). Each appliance's page lists the free checks to try before you pay for a repair.
Is E4 the same on every brand?
