You start a load of laundry, walk away, and come back to find the machine has stopped mid-cycle with a cryptic code blinking on the display. E1. F21. nF. UE. If you’ve ever stood in front of your washing machine wondering what on earth these codes mean, you’re not alone. Error codes are the machine’s way of communicating a specific problem — and once you know how to read them, diagnosing the issue becomes much faster.
At Tri-City Repairs, we service washing machines across Coquitlam, Port Coquitlam, and Port Moody. This guide breaks down the most common error codes across the major brands and tells you exactly what to check.
How Washing Machine Error Codes Work
Modern washing machines use a control board that monitors dozens of sensors throughout the cycle — water temperature, water level, drum speed, motor load, door status, and more. When a sensor reading falls outside the expected range, the control board halts the cycle and displays an error code to identify which system is at fault.
Error codes are brand-specific, so an “E3” on an LG machine means something entirely different from an “E3” on a Whirlpool. Always look up the code for your specific brand and model.
Common Error Codes by Brand
Samsung Washing Machine Error Codes
- 4E / 4C — Water supply error. The machine isn’t filling fast enough. Check that both inlet taps are fully open and the inlet filter screens aren’t clogged.
- 5E / 5C — Drain error. Water isn’t draining within the expected time. Check the drain filter (front-load machines) and drain hose for blockages.
- UE / UB — Unbalanced load. The drum detected an uneven load during spin. Open the door, redistribute the clothes, and restart the spin.
- dE / dC — Door error. The door isn’t fully latched. Close firmly and try again; if it persists, the door latch or switch may need replacing.
- OE / OC — Overflow error. The machine has detected too much water. Turn off the water supply and call a technician — this often indicates a faulty water inlet valve staying open.
LG Washing Machine Error Codes
- IE — Inlet error. Water isn’t filling in time. Check water pressure and inlet valve screens.
- OE — Outlet (drain) error. Similar to Samsung 5E — check the drain filter and pump.
- UE — Unbalanced error. Redistribute the load.
- DE — Door error. Door not latching properly.
- LE — Locked motor error. The motor has overloaded and locked. This often points to an overstuffed drum or a failing motor.
- tE — Thermistor (temperature sensor) error. The water temperature sensor is faulty.
Whirlpool / Maytag Error Codes
- F5 E2 — Door latch error. The door switch isn’t communicating with the control board.
- F8 E1 / LO FL — Low water flow. Check water supply and inlet valve.
- F9 E1 — Long drain. Taking more than 8 minutes to drain. Check the drain hose and pump filter.
- Sud / Sd — Excess suds. Too much detergent was used (very common with HE machines). Run a rinse-only cycle with no detergent.
- F0 E1 — Load size error. The machine thinks there’s no load or too small a load. Redistribute or add items.
GE Washing Machine Error Codes
- E1 — Thermistor (temperature sensor) fault.
- E2 — Control board thermistor fault.
- E3 — Motor control error.
- tE — Temperature error on water heating.
- CL — Child lock is active (not actually an error — press and hold the control lock button).
Bosch / Frigidaire Error Codes
- E17 / F17 (Bosch) — Water inlet problem. No water entering or filling too slowly.
- E18 / F18 (Bosch) — Drain error.
- E23 (Bosch) — Drain pump relay fault.
- E41 (Frigidaire) — Door open error.
- E5A (Frigidaire) — Heating circuit fault.
The First Things to Try for Any Error Code
- Power cycle the machine. Turn it off, unplug it from the wall for 2 minutes, plug it back in, and try again. This clears temporary sensor faults and control board glitches — it resolves roughly 20% of error code situations.
- Check the obvious. Is the door fully closed? Are the water taps open? Is the drain hose kinked?
- Clean the drain filter. For front-load machines, a clogged pump filter is behind many drain-related codes. Access it at the bottom front of the machine.
- Check the load balance. Unbalanced load codes (UE, UB) are always the first thing to rule out on spin errors.
For a deeper dive on spin-related issues, see Washing Machine Shaking Violently During Spin Cycle: Causes and Fixes. And if your machine is also filling slowly before displaying an error code, Why Your Washing Machine Fills Slowly and How to Fix It covers inlet valve and water pressure issues in detail.
When an Error Code Keeps Coming Back
If an error code returns after a power cycle and basic checks, a component failure is likely. The most commonly replaced parts in response to persistent error codes are: door latches, inlet valves, drain pumps, thermistors, and control boards. Some of these — like a door latch — are straightforward replacements. Others — like a control board — benefit from professional diagnosis to confirm the board is actually at fault before spending money on it.
If your washer is skipping phases entirely in addition to showing codes, see How to Troubleshoot a Washer That Skips the Rinse Cycle for related diagnostic guidance.
