Common Appliance Error Codes Explained for LG, Samsung, Bosch, GE, Whirlpool and More

An appliance error code is helpful only if you know what it is trying to tell you. A washer flashing `OE`, a dishwasher showing `E24`, or an oven beeping `F2` can look serious, but many codes point to simple issues like a blocked drain, an unbalanced load, or a door that is not fully latched.

This guide explains common appliance error codes across major brands, including LG, Samsung, Bosch, GE, Whirlpool, Maytag, and Frigidaire. Codes can vary by model, so always check the manual or the label inside the door for the exact meaning. Still, these are the codes homeowners see most often.

What appliance error codes usually mean

Most error codes fall into a few common categories. The letters and numbers may differ by brand, but the problem is often one of these:

Code category	Common meaning	First thing to check
Drain error	Water is not leaving the appliance	Filter, hose, pump area, drain line
Fill error	Water is not entering fast enough	Supply valves, inlet hose, water pressure
Door or lock error	Door is open, misaligned, or not locking	Door seal, latch, lock area
Temperature error	Appliance is not heating or cooling correctly	Airflow, sensor area, element, vents
Motor or spin error	Drum, fan, or motor cannot run properly	Load balance, obstruction, belt area
Leak or overflow error	Water is where it should not be	Hoses, seals, drain pan, float switch

Before taking anything apart, try a basic reset. Turn the appliance off, unplug it if safe to do so, wait a few minutes, then restart it. If the code returns, treat it as a real fault.

Common washer error codes by brand

Washers produce some of the most searched error codes because they stop mid-cycle with clothes and water inside. Here are the common ones.

Brand	Code	What it often means
LG	`OE`	Drain problem
LG	`UE` or `uE`	Unbalanced load
LG	`dE`	Door error
LG	`FE`	Overfill or water level issue
Samsung	`4C` or `4E`	Water supply problem
Samsung	`5C` or `5E`	Drain problem
Samsung	`dC`	Door not closed or not locking
Samsung	`Ub` or `UE`	Unbalanced load
Whirlpool	`F8 E1`	Long fill or no water detected
Whirlpool	`F9 E1`	Long drain
Whirlpool	`F5 E2`	Door lock issue
Maytag	`F8 E1`	Fill problem
Maytag	`F9 E1`	Drain problem

For a drain code, check the drain hose for kinks and clean the pump filter if your model has an accessible one. Coins, hair pins, and lint can block the pump. For a fill code, make sure both hot and cold water valves are fully open and the inlet hoses are not crushed.

For an unbalanced load, pause the washer and redistribute heavy items. One bath mat or a few towels can throw the drum off balance.

Common dishwasher error codes by brand

Dishwasher codes often involve water movement. A dishwasher needs to fill, spray, drain, and heat in the right order. If one step fails, the control board may stop the cycle.

Brand	Code	What it often means
Bosch	`E15`	Water detected in the base or leak protection triggered
Bosch	`E24`	Drain issue
Bosch	`E22`	Filter or sump area needs cleaning
Bosch	`E09`	Heating problem
Samsung	`OC` or `OE`	Over-level water error
Samsung	`LC` or `LE`	Leak sensor triggered
Samsung	`5C`	Drain issue
Whirlpool	`F8 E4`	Float switch or water in drip tray
Whirlpool	`F9 E1`	Drain problem
GE	`H2O`	Water supply issue
Frigidaire	`i20`	Drain problem
Frigidaire	`i30`	Leak or overflow condition

A Bosch `E24` does not always mean the drain pump has failed. It can be a clogged filter, blocked drain hose, or plugged sink connection. A Samsung `LC` or Bosch `E15` needs more caution. If the machine thinks there is a leak, do not keep running cycles to “test it.” That can cause water damage.

Clean the filter first. Then check where the dishwasher drain hose connects under the sink, especially if a garburator was recently installed or replaced.

Common fridge, freezer, oven, and dryer codes

Not every code involves water. Refrigerators, ovens, and dryers use sensors to track temperature, airflow, fans, and door status.

Appliance	Brand	Code	What it often means
Refrigerator	LG	`Er IF` or `IF`	Ice maker fan issue
Refrigerator	Samsung	`5E`	Defrost sensor issue on some models
Refrigerator	Whirlpool	`PO`	Power outage detected
Oven	GE	`F2`	Oven temperature too high or sensor issue
Oven	GE	`F3` or `F4`	Temperature sensor problem
Oven	Whirlpool	`F1`	Control or keypad fault on some models
Dryer	Samsung	`HE`	Heating error
Dryer	Samsung	`tS` or `tO`	Temperature sensor issue
Dryer	LG	`d80`, `d90`, `d95`	Restricted dryer airflow
Dryer	Whirlpool	`AF`	Airflow problem

Dryer airflow codes deserve quick attention. A code like LG `d90` or Whirlpool `AF` often means lint is blocking the vent, the outside flap is stuck, or the vent run is too long or crushed. Poor airflow can make drying slow and may create a fire risk.

Oven codes are different. If an oven shows a temperature sensor or control fault, avoid guessing with parts. High heat, wiring, and electronic controls make oven diagnosis more technical.

What to do before calling for appliance repair

Some error codes have easy causes. Others point to parts, wiring, or sensors that need safe testing. Use this quick checklist before booking service:

Read the full code carefully
`5E` and `SE` can look similar on some displays.
Reset the appliance once
If the code clears and does not return, it may have been a temporary control error.
Check the basics
Look for blocked filters, kinked hoses, closed water valves, overloaded drums, and clogged vents.
Stop if there is water, burning smell, or repeated tripping
Power and water are a bad mix. Do not keep restarting the appliance.
Write down the model number
The same code can mean different things across models.

A good rule is simple: if cleaning, balancing, or checking the supply does not fix it, the appliance likely needs diagnosis. Replacing parts based only on the code can get expensive fast.

The takeaway on appliance error codes

Error codes are clues, not final answers. LG `OE`, Samsung `5C`, Bosch `E24`, Whirlpool `F8 E1`, and similar codes usually point to a system that needs attention, such as draining, filling, locking, heating, or airflow.

Start with the safe checks: reset once, clean filters, inspect hoses, balance the load, and check vents. If the code comes back, stop guessing and use the model number to narrow the fault. That approach saves time, protects the appliance, and helps a repair technician get to the right fix faster.
