Common Washing Machine Error Codes and What They Mean for Andover Homeowners

Published September 2026 | Common Washing Machine Error Codes

When a washing machine throws up an error code, most people assume the machine is done for and start shopping for a replacement. That assumption costs homeowners serious money, often for no reason at all. The truth is that most error codes are your machine's way of flagging a specific, diagnosable fault - and in many cases, it's something an engineer can sort quickly and at a fraction of the cost of buying new.

Myth: An Error Code Means Your Washing Machine Needs Replacing

The Reality

Error codes are diagnostic signals, not death notices. Modern washing machines - whether you have a Bosch Serie, a Samsung AddWash, an LG Direct Drive, a Hotpoint, or a Beko - are packed with sensors that monitor everything from drum rotation and water temperature to door latch position and pump performance. When a reading falls outside normal parameters, the machine logs a fault code and stops the cycle to protect itself from further damage.

That stopping behaviour is the machine working correctly. Our engineers visit homes across Andover regularly to look at machines the owner had already written off. More often than not, the machine is perfectly repairable - frequently with a part that costs less than 60 pounds and a single call-out visit.

Washing machines typically last 10 to 15 years with reasonable maintenance. If your machine is under eight years old and showing an error code, the default assumption should be repair, not replace. A new mid-range machine from a brand like Hotpoint or Beko will typically cost 350 to 500 pounds. A repair for most common faults will come in at 80 to 200 pounds. The maths usually points in one direction.

The key shift in thinking is this: an error code is your machine asking for help, not surrendering. Treat it the same way you'd treat a warning light on your car - investigate before you write the thing off.

Myth: You Can Just Reset the Machine and Carry On

The Reality

Switching the machine off at the wall, waiting 30 seconds, and turning it back on will clear the display. A lot of people do this and assume the problem has gone away. It hasn't.

Resetting a washing machine clears the active fault display but does nothing about the underlying issue. The sensors that triggered the code are still picking up the same problem. What typically happens is the machine restarts, runs for a while, and then the same code appears again - sometimes mid-cycle, leaving your laundry sitting in a drum full of cold water with no way to open the door.

Worse, running the machine repeatedly through reset cycles while a fault is present can escalate the damage. A machine flagging a motor overload and being continually reset can burn out components that would otherwise have been fine. Think of the error code as a warning light. Resetting without investigating is like covering that warning light with tape - the light disappears, the problem absolutely does not.

If the same code returns after a reset - particularly within the first part of a new cycle - treat that as confirmation the fault needs a proper look, not another reason to hit the off switch again.

Myth: All Washing Machine Error Codes Mean the Same Thing

The Reality

There is no universal standard for washing machine error codes. Each manufacturer - and sometimes each product range within the same brand - uses its own coding system. An E1 on a Hotpoint typically indicates a water fill issue. An E1 on a Beko can flag a thermistor fault. On some older LG machines, E1 relates to the door lock. Same code, three completely different faults, three completely different fixes.

This is why searching an error code online without first knowing the exact make and model of your machine will often send you in entirely the wrong direction. Our engineers always start with the model number - usually printed on a sticker inside the door aperture or on the back panel - before interpreting any fault code. Without it, the code alone tells you very little.

Here is how common codes typically break down by brand:

• Bosch / Siemens: F codes throughout. F17 typically flags a door fault. F21 commonly points to a pump blockage. E18 means drainage did not complete in time.
• Hotpoint / Indesit: Both F and E codes used. F05 commonly indicates drain pump issues. F08 usually flags a heating fault.
• Samsung: DC codes relate to drum imbalance. ND means no drain. A 4C or 4E code points to a water supply problem.
• LG: LE is a motor error. OE means drainage failure. IE indicates a water inlet fault.
• Beko: E-series codes, though these vary significantly between model generations - always check the specific model.

When you log a fault through the Voltrade GoFIX diagnostic tool, it cross-references your machine's make, model, and reported error code to identify the most likely causes before an engineer arrives - which means faster diagnosis and fewer wasted visits for everyone.

Myth: F Codes and E Codes Always Signal an Expensive Repair

The Reality

F codes and E codes cover the full spectrum of fault severity - from a clogged filter that takes minutes to clear, all the way through to a failed motor controller that might cost between 150 and 300 pounds to repair. The letter prefix tells you almost nothing about cost. The specific number after it, combined with your machine's make and model, is what actually matters.

Some of the codes our engineers across Hampshire encounter most frequently include:

• E18 / F18 (Bosch): Drainage did not complete within the expected time. Most commonly caused by a blocked pump filter or a kinked drain hose. Engineers typically clear these in under 20 minutes. If the filter just needs cleaning, you pay the call-out fee and nothing more.
• F21 (Hotpoint / Indesit): Again, a filter or pump blockage in the majority of cases. When the pump motor itself has failed, replacement parts commonly cost 30 to 60 pounds plus labour.
• ND (Samsung): No drain detected. Start with the filter before assuming pump failure - this code is frequently triggered by blockages, not mechanical failure.
• dE / dE1 (LG): Door error. Often a worn door seal pressing against the latch mechanism, or a small item of laundry stopping the door from clicking shut properly.
• F08 (Hotpoint): Heating fault. This can mean a failed heating element - typically 50 to 90 pounds for the part - or a thermistor sensor, which commonly costs under 20 pounds to replace.

Even on higher-end machines like a Bosch Serie 6 or a Samsung ecobubble, many of the most frequent error codes point to maintenance issues or inexpensive components rather than major faults. Proper diagnosis is everything - which is why jumping to conclusions about cost based on a code alone almost always leads homeowners astray.

Myth: A Drainage Error Always Means a Broken Pump

The Reality

A drainage error tells you the machine detected that water did not drain within its expected time window. The pump is one possible cause - but it is not the first thing to check, and in our experience it is often not the culprit. This is one of the most persistent assumptions our engineers encounter across Andover and the wider Hampshire area, and it regularly leads people to authorise pump replacements they did not actually need.

Before suspecting the pump, work through this sequence:

1. Check the filter. On most front-loading machines, it is behind a small access panel at the bottom front. Unscrew it slowly with a towel underneath - water will come out. Clear any debris, coins, hair grips, or accumulated fluff. This single step fixes drainage errors in a significant proportion of cases.
2. Check the drain hose. It runs from the back of the machine into a standpipe or under-sink trap. If it is kinked, squashed by the machine being pushed too close to the wall, or partially blocked with lint, water cannot drain efficiently regardless of whether the pump is working.
3. Check the standpipe height. The drain hose outlet should ideally sit between 60cm and 100cm from the floor. If it is positioned too high, the machine may struggle to pump water up to that point.
4. Listen during the drain cycle. If you hear a low hum or whirring, the pump is running. Complete silence suggests the pump may have failed. A grinding noise suggests something may be caught in the impeller - often a coin or small hair clip.

A pump replacement on most common machines - Hotpoint, Beko, Indesit, mid-range Samsung - typically costs between 80 and 180 pounds including parts and labour. It is a sensible repair when the pump has failed. It is wasted money when a blocked filter was the actual problem all along.

What Actually Matters - Expert Advice

Error codes are useful tools, but only when you interpret them correctly and start with the right machine information. Here is what our engineers would tell any homeowner before they call anyone out:

Get the exact model number first. It is on a sticker inside the door aperture or on the back of the machine. Without it, any code lookup is largely guesswork. The same code means different things on different machines from the same brand, and acting on the wrong interpretation wastes time and money.

Do not repeatedly run the machine through the same fault. If it is stopping on a code, let it stop. Forcing it through cycle after cycle can turn a minor fault into a significantly more expensive one, particularly with motor and heating-related errors.

Check the obvious things before calling anyone. Blocked filter, kinked drain hose, overloaded drum, items caught around the door seal. These account for a substantial share of the error codes our engineers in Andover are called out to diagnose, and many of them are things you can check yourself in five minutes.

Know which faults need a professional. Codes relating to the heating circuit, motor control, or the main PCB (printed circuit board) are not DIY territory. A main PCB replacement on a Bosch or Samsung can cost between 150 and 350 pounds - and buying the wrong part after a misdiagnosis wastes that money entirely. For these faults, proper diagnosis before ordering anything is essential.

Apply the half-price rule. If the repair estimate exceeds roughly half the cost of a comparable new machine, replacement starts to make more financial sense. For a budget Beko bought at 300 to 350 pounds, that threshold is reached fairly quickly. For a premium LG or Bosch bought at 600 to 800 pounds, most common repairs fall well within it.

Myth-Busting Questions

Does turning a washing machine off and on again actually fix error codes?

It clears the display, but it does not fix the fault that triggered it. If the same code comes back after a reset - particularly within the first part of a cycle - the underlying problem is still present and needs diagnosing. Repeated resets while a fault is active can also cause additional component damage, particularly with motor overload and heating-related errors. A reset is a useful first step, not a solution.

Are some washing machine brands more reliable common error codes?

All major brands - Bosch, Samsung, LG, Hotpoint, Beko - generate error codes when sensors detect faults. Reliability differences tend to show up in how often specific components fail over time, not in the coding systems themselves. Bosch and LG have strong track records for motor longevity. Hotpoint and Beko are known for accessible part availability across the UK, which can make repairs more cost-effective when something does eventually go wrong.

Can I look up my error code online and fix the problem myself?

For some codes, yes - particularly drainage errors where the fix is cleaning the filter or repositioning the drain hose. For anything involving the heating element, motor, PCB, or internal wiring, it is worth getting a qualified engineer to assess it properly. Misidentifying the faulty component and ordering the wrong part is a common and costly mistake, and some repairs involve live electrical components that carry real risk if handled incorrectly.

Frequently Asked Questions

How much does it typically cost to repair a washing machine error code fault in Andover?

Costs vary depending on the fault. A blocked filter causing a drainage error might cost nothing beyond a call-out fee, which typically runs to 60 to 85 pounds in the Andover area. Pump replacements commonly cost between 80 and 180 pounds including parts and labour. Door seal replacements typically come in at 60 to 120 pounds. Main PCB or motor control faults sit at the higher end - commonly between 150 and 350 pounds, depending on the machine brand and model.

My Bosch washing machine is showing an E18 error code - what does this mean?

An E18 on a Bosch washing machine means the machine failed to drain within its expected time window. The most common cause is a blocked pump filter - the removable filter at the bottom front of the machine. Unscrew it slowly over a towel, clear any debris, and retry the cycle. If E18 persists, check the drain hose for kinks or blockages. If neither resolves it, the drain pump itself may need inspection by an engineer.

Should I repair or replace my washing machine if it keeps showing error codes?

If your machine is under eight years old and the repair estimate is less than half the price of a comparable replacement, repair is usually the better option financially. Recurring error codes after a repair can sometimes indicate an underlying electrical issue, particularly on older machines. Our engineers can carry out a proper assessment before you commit to either repair costs or a new purchase - getting that informed view first is nearly always worth doing.
