Quick Answer
Washing machine error codes generally fall into five categories regardless of brand: water inlet faults (won't fill), drainage faults (won't drain), door/lid lock faults, motor or drive faults, and sensor or control board faults. The exact code (E10, E20, F5, dE, UE, and similar) varies by manufacturer, but the fault category it points to is usually consistent.
Exact codes and their meanings vary between brands and even between models from the same brand — always check your specific model's manual where possible, and treat the categories below as a reliable starting point rather than an exact universal code list.
A washing machine flashing an error code is actually more useful than one that just stops silently — the code is the machine telling you roughly where to look. The challenge is that every manufacturer uses its own numbering, so the same underlying fault might show as E20 on one brand and dE on another.
This guide groups the most common washing machine error codes by what they generally mean, with real example codes from major brands sold in Melbourne, so you know roughly what's wrong before booking a technician.
Water Inlet Faults — Machine Won't Fill
These codes appear when the machine can't detect enough water entering the drum within the expected time. Common examples: E10/E11 (LG, Samsung), F1 (Bosch), IE (LG/Samsung 'inlet error'), and WF or H2O-style codes on some European brands.
- Check both hot and cold water taps behind the machine are fully open
- Check inlet hoses for kinks or a blocked mesh filter where the hose connects to the tap
- Rule out a general water supply issue by checking another tap in the house
Drainage Faults — Machine Won't Drain
These are among the most common codes seen, because the drain path is the part most likely to be blocked by lint, coins or fabric. Common examples: E20/E21 (LG, Samsung), F5 (Bosch), dE or 5E-style codes, and OE ('outlet error') on several Asian brands.
- Check the drain hose isn't kinked or crushed behind the machine
- Clean the drain pump filter — usually a small hatch at the front-bottom of front loaders — this alone resolves a large share of drainage codes
- Check nothing is visibly blocking the drain hose outlet
Door and Lid Lock Faults
These appear when the machine's sensor can't confirm the door or lid is fully closed and locked, which is a safety interlock — the machine won't run without it. Common examples: E40/E41 (LG, Samsung), dOOr or dr codes, and F0-style codes on some brands. If the door is closed but the machine still shows this fault, or the door has become physically stuck locked, see our dedicated guide on a washing machine door that won't open or unlock.
Motor and Drive Faults
These point to the drum not spinning as expected — either not turning at all, turning too slowly, or the machine detecting resistance it shouldn't. Common examples: E3x-range codes (LG, Samsung), F3/F4 (Bosch), and UE or dU codes, which usually specifically mean an unbalanced load rather than a motor fault itself.
- An 'unbalanced load' code (often UE or dU) usually just means redistributing the washing evenly and restarting — not a genuine fault
- A motor or drive fault that persists across multiple empty-drum test runs is more likely a real component failure
Sensor and Control Board Faults
These are the least predictable category and the ones most worth calling a technician for rather than guessing — they can relate to temperature sensors, water level sensors, or the main control board itself. Common examples: E5x/E6x-range codes, and generic 'PF' (power failure) or communication error codes that sometimes clear on their own after a full power cycle but return if the underlying sensor is failing.
What's Safe to Check Yourself vs When to Call a Pro
Safe to Check Yourself
- Note the exact code shown and check it against your specific model's manual if available
- Check water taps are open and inlet hoses aren't kinked (for fill-related codes)
- Clean the drain pump filter (for drain-related codes) — this is a normal homeowner-safe maintenance task on most front loaders
- Check the door is fully closed and nothing (fabric, drawstring) is caught in the seal
- Try a full power-off, wait 60 seconds, then power back on — this clears some sensor/control faults but won't fix a genuine hardware fault
Always Call a Licensed Technician
- Diagnosing and replacing a faulty water inlet valve
- Replacing a failed drain pump or motor
- Diagnosing door lock mechanism or interlock sensor faults
- Diagnosing and replacing a faulty control board
Frequently Asked Questions
Why does the same error code mean something different on different brands?▼
Manufacturers design their own fault-detection logic and numbering independently, so there's no single universal standard — codes need to be checked against your specific brand and, ideally, model.
Can I look up my exact error code online?▼
You can, but results vary widely in accuracy. The categories in this guide (fill, drain, door lock, motor, sensor) are a reliable starting point regardless of brand, even where you can't confirm the exact official meaning of your specific code.
My washing machine shows an unbalanced load code every time — is that a fault?▼
Not necessarily. If it clears after redistributing the load manually and restarting, it's the machine working correctly. If it appears even with a small, evenly distributed load, that points to a genuine drum or suspension fault.
Is it safe to keep restarting the machine when an error code appears?▼
For a one-off unbalanced load code, yes. For drain, fill, or door lock codes that repeat after a proper check (clearing the filter, checking hoses, checking the door), repeated restarts without addressing the cause can worsen the fault — it's a sign to book a washing machine repair.
How much does it cost to fix a washing machine error code fault?▼
It depends entirely on the underlying cause — a blocked filter is often resolved on the spot at minimal cost, while a control board or motor replacement is a larger repair. We diagnose the exact code and part needed before quoting.
