Samsung Washing Machine Error Codes Guide from Appliance Repair Engineers in Accrington

Published September 2026 | Samsung Washing Machine Error Codes Guide

We asked our Appliance Repair engineers the questions Accrington homeowners ask most. If your Samsung washing machine has stopped mid-cycle and is showing an unfamiliar code on the display, this guide will walk you through what each fault means, what you can check yourself, and when to call a professional.

What Do Samsung Washing Machine Error Codes Actually Mean?

Samsung washing machines use a built-in fault detection system that monitors dozens of processes during every cycle. When something falls outside the expected range, the machine pauses and displays a code on the control panel instead of a programme countdown. That code points to a specific component or process that needs attention.

The format of the codes varies depending on the age of your machine. Older Samsung washers typically display E-prefix codes like E2 or E3. Machines made roughly from 2010 onwards tend to use alphanumeric codes like 4E, 5E, or 3C. In some cases the same fault is written differently across models - for example, 5E and SE mean exactly the same thing: a drainage fault.

What the code tells you is the category of the problem, not always the specific cause. A 4E code means water is not entering the drum as expected - but that could be a blocked filter, a closed tap, a kinked hose, or a failed valve. Our engineers across the Accrington area use these codes as a starting point for diagnosis rather than a definitive answer, and that distinction matters when you're deciding whether to tackle something yourself or book a professional.

What Does the 4E or 4C Error Code Mean on a Samsung Washing Machine?

The 4E code (shown as 4C on some Samsung models) is a water supply error. It means the machine has started a programme but has not been able to draw in water within the expected time. You will usually see it appear within the first few minutes of a cycle.

Before calling anyone out, run through these checks in order:

1. Confirm the water supply tap at the back of the machine is fully open. It is more common than you would expect to find it was accidentally turned off during a previous maintenance job.
2. Check the inlet hose running from the tap to the back of the machine for any kinks or tight bends restricting the flow.
3. Remove the inlet filter mesh, which sits where the hose connects to the machine. Rinse it under the tap to clear any debris or limescale build-up.
4. Check water pressure in the rest of the house. If kitchen and bathroom taps also seem weak, the issue may be with your supply rather than the machine.

If none of those steps clears the code, the inlet solenoid valve itself has likely failed. This is a straightforward component replacement for a trained engineer. Expect to pay typically between 80 and 150 pounds for parts and labour on a Samsung machine. The part is widely available for most models sold in the UK over the past decade.

What Does the 5E or SE Error Code Mean and Is It Serious?

The 5E code (or SE on older Samsung machines) is a drainage fault. It means the machine attempted to pump water out but could not empty the drum within the allotted time. You will typically see it at the end of a wash cycle, during a rinse, or when a spin is about to begin.

This is one of the most common fault codes our engineers deal with across Lancashire, and in a significant number of cases the fix is something you can do yourself:

1. Check the drain hose at the back of the machine for kinks. Also check how far it inserts into the standpipe - Samsung recommends no more than 15cm of insertion to prevent the machine from siphoning water back in during a cycle.
2. Locate the pump filter, which on most Samsung front-loaders sits behind a small access panel at the bottom front of the machine. Lay a towel down first, open the panel, and unscrew the filter cap slowly - water will flow out. Remove any debris, coins, hair, or small items you find inside.
3. Once the filter is clean, run a drain-only programme to test whether the issue is resolved.

If the code returns after cleaning, the pump motor has most likely failed. Drain pump replacement on a Samsung machine typically costs between 100 and 180 pounds including labour. It is a common repair and turnaround is usually quick if the part is in stock.

What Does the 3E or 3C Error Code Mean on a Samsung Washer?

The 3E code indicates a motor fault. It means the machine's control board is not receiving the correct signal from the motor or a motor-related component. Unlike the 4E or 5E codes, this one is not something you can fix with a filter clean - it needs a trained engineer with diagnostic equipment.

Most Samsung washing machines made since around 2010 use a brushless inverter motor, which is generally more reliable than older brush-based motors. However, the motor hall sensor - a small component that tracks motor speed and position - is a known failure point and can trigger a 3E code even when the motor itself is perfectly functional.

Our Accrington engineers use the Voltrade GoFIX diagnostic tool to distinguish between a sensor fault and a full motor failure before ordering any parts, because the cost difference is significant. A hall sensor replacement typically runs between 80 and 130 pounds. A full motor replacement on a Samsung machine commonly costs between 180 and 320 pounds depending on the model. Getting a proper diagnosis upfront saves you from paying for the wrong repair, particularly on machines that are over five years old where the economics of repair need careful consideration.

What Is the Ub or Ur Error Code on a Samsung Washing Machine?

Ub (or Ur on some Samsung models) stands for unbalanced load. The machine has detected that laundry inside the drum is unevenly distributed, and it has paused the spin cycle to prevent excessive vibration from damaging the drum bearings, suspension, or the machine's external casing.

This is not a mechanical failure - it is the machine's safety system working correctly. The steps to resolve it are:

1. Open the door and manually rearrange the laundry so it is spread evenly around the drum rather than bunched to one side.
2. Avoid washing single heavy items, such as a duvet or a pair of denim jeans, on their own. Adding a couple of towels to the load helps balance the weight distribution.
3. Check that the machine is sitting level on the floor. All four feet should make firm contact. Use a spirit level across the top of the machine and adjust the levelling feet underneath if needed.

If you are getting a Ub code repeatedly even with properly balanced loads, the suspension rods or shock absorbers that cushion the drum during spin may be worn out. This is common on machines over six or seven years old. Suspension rod replacement typically costs between 90 and 160 pounds with labour included.

What Does the tE or tC Error Code Mean and Should I Be Worried?

The tE code (sometimes displayed as tC) is a temperature sensor fault. It means the machine's thermistor - the component that monitors water temperature - is reporting a reading that falls outside its normal operating range. This usually means the sensor has failed, though in some cases it can indicate a problem with the heating element itself.

When a tE code appears, the machine will typically complete the mechanical parts of a cycle but without heating the water properly. That means clothes come out washed but at a much lower temperature than selected, which matters for hygiene cycles and heavily soiled loads.

In Accrington and across Lancashire more broadly, we see this fault more often on machines that are five or more years old, particularly those that have been in heavy use. Replacing a thermistor is a relatively quick repair - typically between 70 and 120 pounds all in. If the heating element has failed as well, expect to pay between 120 and 200 pounds. An engineer will test both components before replacing anything so you are not paying for guesswork. This type of fault appears on Bosch, Hotpoint, and LG machines too, but the specific Samsung parts and wiring configuration means it is worth using an engineer experienced with that brand.

What Does the LC or LC1 Code Mean on a Samsung Washing Machine?

The LC and LC1 codes are leak detection alerts. Samsung washing machines fitted with a leak sensor will display these codes when moisture is detected in the base of the machine, either from an active leak or from residual water that has accumulated over time.

Do not simply power cycle the machine and continue using it if this code appears. Even a minor internal leak can cause water damage to floor coverings and, more seriously, can put electrical components at risk if water reaches them during operation.

Start by pulling the machine away from the wall and checking both the inlet and drain hoses at their connection points. Tighten any loose fittings and replace any hose that looks brittle, cracked, or perished. If the hoses look fine, the leak may be coming from the door seal, the detergent drawer housing, or internally from the pump or drum bearing area.

Our engineers in Accrington will typically run a diagnostic cycle with access panels removed to pinpoint where water is escaping. Door seal replacement costs between 80 and 140 pounds. Drum bearing repairs, which can also cause internal leaking alongside noise, are more involved and typically cost between 150 and 280 pounds depending on the model and accessibility of the bearing assembly.

When Should I Try to Fix a Samsung Error Code Myself and When Should I Call an Engineer?

The honest answer is that it depends on the code. There is a clear line between faults caused by blockages or user error, which you can often resolve at home, and faults caused by component failure, which require disassembly and professional diagnosis.

Checks you can carry out yourself:

• Cleaning the pump filter to clear a 5E drainage fault
• Cleaning and reinstalling the inlet filter mesh for a 4E water supply fault
• Redistributing laundry and levelling the machine for a Ub balance fault
• Checking and tightening hose connections for an LC leak alert

Call a trained engineer for:

• Motor faults (3E or 3C) - testing and replacement require specialist tools
• Heating element or temperature sensor failure (tE or tC)
• Any code that returns immediately after a reset or filter clean
• Any situation where you can hear grinding, banging, or detect a burning smell
• Codes you cannot identify with confidence, particularly on newer Samsung models

Attempting to access electrical or motor components without the right equipment can cause further damage and creates a genuine safety risk. A diagnostic call-out in the Accrington area typically costs between 50 and 90 pounds, and most engineers will offset that fee against the cost of the repair if you proceed.

How Much Does It Typically Cost to Repair a Samsung Washing Machine in Accrington?

Repair costs in Accrington sit broadly in line with the rest of Lancashire. Here is a realistic range for the most common Samsung washing machine repairs our engineers carry out:

• Pump filter service or minor blockage clearance: 50 to 90 pounds
• Inlet valve replacement (4E fault): 80 to 150 pounds
• Drain pump replacement (5E fault): 100 to 180 pounds
• Door seal replacement (LC fault or physical damage): 80 to 140 pounds
• Thermistor replacement (tE fault): 70 to 120 pounds
• Heating element replacement (tE fault): 120 to 200 pounds
• Motor hall sensor replacement (3E fault): 80 to 130 pounds
• Full inverter motor replacement (3E fault): 180 to 320 pounds
• Drum bearing replacement: 150 to 280 pounds

A commonly used rule of thumb is this: if a repair quote comes to more than half the cost of a comparable replacement machine, weigh up the options carefully. Mid-range Samsung washing machines in the UK currently retail between roughly 450 and 900 pounds, putting that repair threshold at around 225 to 450 pounds. Our engineers will always give you a clear assessment of the repair's value before you commit to anything.

Can a Diagnostic Tool Help Me Understand a Samsung Error Code Before an Engineer Arrives?

Yes, and this is something we actively encourage. The Voltrade GoFIX diagnostic tool is built for exactly this situation - it helps homeowners understand what a fault code means, narrow down the likely cause, and decide on the right next step before picking up the phone.

GoFIX walks you through a series of guided questions based on the specific code your Samsung machine is displaying: what the machine was doing when the fault appeared, whether you have already tried a reset, what sounds (if any) the machine is making, and what its service history looks like. From those inputs, it can often distinguish between a maintenance task you can resolve yourself and a component failure that needs a professional.

This is particularly useful with Samsung machines because many error codes can have multiple root causes. The 5E drainage code, for example, can come from a blocked filter, a failed pump, or an incorrectly routed drain hose, and the right response is different in each case. Using GoFIX before booking means you arrive at the conversation with an engineer better informed, and it gives the engineer a head start on bringing the correct parts to the job.

Samsung washing machines are well-engineered appliances, and the error code system is genuinely useful rather than alarming. Most faults, once properly identified, have a clear and cost-effective fix. Whether you are looking at a basic 4E water supply fault, a recurring 5E drainage issue, or something more involved like a 3E motor fault, the starting point is always the same: read the code, run the relevant checks, and call in a professional for anything electrical or mechanical. With the right diagnosis, most Samsung machines can be back in service within a few days.

Frequently Asked Questions

How do I reset a Samsung washing machine after an error code appears?

Press and hold the Start/Pause button for around five seconds to cancel the active programme, then switch the machine off at the wall plug. Leave it unplugged for two minutes before switching it back on. If the code was caused by a temporary sensor glitch, this is usually enough to clear it. If the same code reappears immediately or at the same point in the next cycle, the underlying fault is still present and a reset will not resolve it.

Does a Samsung washing machine error code void the warranty?

An error code appearing on the display does not affect your warranty in any way. Samsung typically provides a two-year manufacturer warranty on washing machines sold in the UK. If your machine is within that period and displaying a fault, contact Samsung support before having an independent engineer open the machine, as independent repair work carried out during the warranty period can sometimes affect your cover depending on the terms.

Can I use the Samsung SmartThings app to read error codes?

Yes, many Samsung washing machines manufactured from around 2018 onwards support Samsung's Smart Check feature, accessible through the SmartThings app. The app uses your phone's camera to read the error code from the display and provides basic guidance on what it means. It is a useful first step for identifying codes on newer connected models, though it does not replace hands-on diagnosis for mechanical or electrical faults.

Are Samsung error codes the same across all models and ages of machine?

Not entirely. Samsung has updated its error code system across different generations of machines. Older models commonly use E-prefix codes such as E2 or E4, while machines from roughly 2010 onwards use the current format with codes like 4E, 5C, or 3C. The meaning is often similar or identical, but the display format differs. If you are unsure which system your machine uses, cross-reference the code with your model's instruction manual or Samsung's UK support pages.
