You started the wash for 1 hour, but after 2 hours the drum is still spinning and the display shows “5 minutes”? Or did the machine suddenly add an extra 30 minutes to the program for no apparent reason? This problem is familiar to many owners of washing machines - from budget Indesit and Candy up to bonus Bosch and LG. In 80% of cases, this is not a breakdown, but a feature of the equipment or an operating error. But in the remaining 20%, delays indicate malfunctions that can lead to serious repairs.

In this article we will look at all possible reasons, for which the washing machine exceeds the specified washing time - from a banal overload of laundry to failures in the control module. You will learn how to diagnose the problem yourself, when you can do without a technician, and in what cases it is dangerous to delay repairs. We also compiled table of common errors for popular brands and have prepared a checklist for quickly checking the machine.

1. Drum overload: the most common cause of delays

Washing machine manufacturers always indicate the maximum load in kilograms - usually from 5 to 12 kg, depending on the model. However actual drum capacity often less than stated: for example, in a 7 kg machine it is comfortable to wash 5–6 kg of dry laundry. If you load more, the weight sensors will not work correctly and the program will automatically extend the wash time.

How does it work? In case of overload:

  • 🌀 The drum cannot distribute the laundry evenly — the machine spends extra cycles trying to balance the load.
  • 💧 Water penetrates into fabric less easily — the turbidity sensor detects poor rinse quality and adds additional cycles.
  • ⚡ Engine running at maximum power - this can cause overheating and an emergency stop with subsequent restart of the program.

Overload is especially critical for machines with vertical loading (for example, Samsung WD80K5410OW or Electrolux EWT 1064 ILW). In them, laundry accumulates at the bottom of the drum, blocking rotation. Some models even give an error UE (Unbalanced Error) and stop until things are manually redistributed.

⚠️ Attention: If the machine systematically adds 20–40 minutes to each wash, check not only the weight, but also fabric type. Down jackets, blankets and rugs take up more volume than cotton T-shirts of the same weight. For example, 5 kg of down jackets can take up the entire drum of an 8 kg machine.
💡

To avoid overload, use the “palm” rule: place your hand on the laundry in the drum - if there is a space of 2-3 fingers between the clothes and the walls, loading is optimal.

2. Wrong program selection: hidden time settings

Many users do not pay attention to actual duration of programsspecified in the instructions. For example, in cars Bosch Serie 6 the "Cotton 60°C" mode takes 2 hours 45 minutes, and not 1 hour 30 minutes, as it seems on the timer. Manufacturers often include in programs hidden stages:

  • 🔄 Pre-wash (if the option is enabled Extra Rinse or Pre-Wash).
  • 🌡️ Heating water to the exact temperature (in machines with a temperature sensor, e.g. LG F4V9RWP2T).
  • 💦 Extra rinse (automatically added when foam level is high).

Another trap is modes with automatic weighing (for example, AutoDose in Siemens or AI Wash in LG). The machine can automatically increase the time if it finds the laundry too dirty. In this case, the display will show the original time, and the actual time will be longer.

How to check? Start the wash program Quick 30 minutes (if any) with half the normal load. If the machine meets the deadline, the problem is the choice of mode, not a breakdown.

3. Problems with water supply: low pressure or blockages

If the washing machine takes a long time to collect water or does it in jerks, the program is automatically extended. Normal tank filling time is 2–5 minutes. If the process takes 10–15 minutes, check:

Reason Signs How to fix
Low water pressure in the system The machine draws water with pauses and makes “grunting” sounds. Check the pressure in the tap, open it completely
Clogged inlet filter mesh Water flows in a thin stream, the machine gives an error E1 or 4E Clean the filter (located on the back wall, behind the hose)
Kinked or clogged inlet hose The sound of water, but the tank fills slowly Check the hose for kinks, blow it out
Intake valve malfunction Water does not come in at all or drips very slowly Valve replacement required (part costs RUB 800–1,500)

In cars with the system AquaStop (for example, Miele W1) with low pressure, leakage protection may be triggered, which also increases the washing time. If the water pressure is normal but the problem persists, check water level sensor (pressostat). If it malfunctions, the machine “thinks” that the tank is empty and constantly adds water.

How to clean the mesh filter?

1. Turn off the water and disconnect the inlet hose from the machine. 2. Using pliers, carefully pull the mesh out of the inlet hole. 3. Rinse it under running water using a toothbrush to remove plaque. 4. Reinstall and check the tightness of the connection.

4. Sensor malfunctions: temperature, balance, turbidity

Modern washing machines are equipped with several sensors that directly affect the duration of the wash. If at least one of them does not work correctly, the program may go into a loop or artificially lengthen.

Top 3 sensors responsible for delays:

  • 🌡️ Temperature sensor (NTC) - if he lies, the machine will heat the water for a long time or, conversely, overheat it, which will trigger an emergency pause. Typical error: H1 or HE.
  • ⚖️ Balance sensor - if it breaks down, the machine will endlessly try to distribute the laundry, adding rotation cycles. Error: UE or UB.
  • 💧 Water turbidity sensor - if it is dirty or broken, the machine will decide that the water is not clean enough and will run additional rinses. Error: OE or E2.

How to diagnose? Run test mode (for most models this is holding the buttons Start/Pause + Temperature within 5 seconds). If the machine gives a sensor error, it needs to be cleaned or replaced. For example, in Samsung WW60J3260FW The turbidity sensor is located at the bottom of the tank and often becomes clogged with lint.

⚠️ Attention: If the machine suddenly starts washing longer after power outages or a power surge, the problem may be resetting the sensors. Try full reset (unplug the machine for 10 minutes, then turn it on again).

5. Malfunctions of the heating element and water heating

If the washing machine takes a long time to heat water or does not heat it at all, this directly affects the washing time. Normal heating time to 60°C is 15–20 minutes. If the process takes 40–60 minutes, check:

  • 🔥 Condition of the heating element — there may be scale on it (especially if you wash at 90°C less than once a month).
  • 📉 Mains voltage — at low voltage (less than 200V), the heating element heats water 2–3 times longer.
  • 🛠️ Heating element contacts - oxidation or broken wiring leads to intermittent operation.

How to clean the heating element? Use citric acid (100 g per empty drum, Cotton 90°C mode) or specialized products like Magic Power. If the heater burns out (checked with a multimeter), it will have to be replaced. Average cost of heating elements for cars Indesit or Ariston — 1200–2000 ₽, for Bosch or Siemens — 2500–3500 ₽.

In cars with inverter motor (for example, LG FH4G1BCS2) a faulty heating element can cause an error HE and a complete stop of the program. In this case, a code will appear on the display and the washing time will freeze.

Check the voltage at the outlet (should be 220-230V)|

Start the wash at 60°C and touch the sunroof glass after 20 minutes (should be warm)|

Shine a flashlight into the drum - if a thick layer of scale is visible on the bottom, the heating element requires cleaning |

Test the heating element with a multimeter (resistance should be 25–40 Ohms)

6. Control module failures: when the electronics are to blame

If all mechanical reasons are excluded, but the machine still takes longer to wash, the problem may lie in control module (control board, the “brains” of the machine). Typical symptoms:

  • ⏱️ The timer resets or “freezes” at one value.
  • 🔄 The program starts again after a pause.
  • 📛 Random characters or errors like E67 (for Samsung) or F18 (for Bosch).

Reasons for module failures:

  • 🌩️ Power surges - even one sudden blackout can damage the microcircuits.
  • 💦 Moisture ingress — condensation or leakage onto the board leads to corrosion of the contacts.
  • 🕰️ Outdated firmware - in cars with Wi-Fi (for example, Samsung WW90T554DAW) software bugs can cause freezes.

What to do? If the machine is under warranty, contact the service center. Repairing a board yourself requires soldering equipment and knowledge of electronics. In some cases it helps flashing (for example, for models LG with the system SmartThinQ), but it's risky without experience.

⚠️ Attention: If after a module failure the machine starts turn on independently at night or run programs without a command, this is a sign critical board damage. Immediately disconnect it from the network and call a technician - further operation is dangerous!
💡

In 60% of cases, control module failures are caused by unstable voltage. Use a surge protector or voltage stabilizer (for example, Resanta ASN-2000 N/1-C) to protect equipment.

7. External factors: water, foam, ventilation

Sometimes the reason for delays lies not in the machine, but in her working conditions. Here's what can affect wash time:

  • 🧼 Excess foam - if you use too much powder or the wrong detergent (for example, for hand washing), the turbidity sensor will detect "dirty" water and add rinses. In cars AEG or Electrolux this may add 30 to 50 minutes to the time.
  • 💨 Poor ventilation — if the machine is in a cramped closet or next to heating devices, it may overheat. In this case, the control module artificially slows down the programs to avoid overload.
  • 🚰 Hard water — a high content of calcium and magnesium salts leads to the rapid formation of scale on the heating element and sensors, which increases the heating and washing time.

How to minimize the influence of external factors?

  • 📏 Use measuring spoons for powder - 1 tbsp is enough for 1 kg of laundry. spoons (20 g) of concentrated product.
  • 🌡️ Install the machine in a ventilated place, leaving gaps of 5-10 cm on all sides.
  • 💧 For hard water use softeners (for example, Calgon) or magnetic filters.
💡

If the machine often freezes during the rinsing phase, try running the program Rinse + Spin without underwear. If the execution time exceeds 20 minutes, the problem is with the turbidity sensor or drain pump.

FAQ: Frequently asked questions about wash delays

The machine adds time during the “Rinse” stage. What's the matter?

Most likely, the water turbidity sensor has tripped. Reasons:

  • Too much powder or conditioner.
  • The drain pump filter is dirty (needs to be cleaned).
  • The sensor itself is faulty (diagnostics required).

Try running the program without detergents - if the time returns to normal, the problem is in the dosage.

Why does the machine wash longer at night than during the day?

Probably at night in your house water pressure drops (for example, due to heavy use by neighbors) or network voltage decreases (many people wash at night, creating a load). Check:

  • Tap water pressure at night.
  • The voltage in the socket (must be at least 200V).

If the problem is confirmed, wash in the daytime or install a voltage stabilizer.

Typewriter Indesit shows error F05 and washes for 4 hours instead of 1. What should I do?

Error F05 means water heating problem. Reasons:

  • The heating element has burned out (needs replacement).
  • The heating element relay on the control module is faulty.
  • Open circuit in the heater circuit.

Disconnect the machine from the network, check the heating element with a multimeter (resistance should be 25–40 Ohms). If the part is burnt out, replace it.

Is it possible to interrupt the wash if the machine has already added extra time?

Yes, but with caution:

  • Click Pause/Start and wait for the hatch to unlock.
  • If there is water in the drum, drain it through the emergency hose (usually located below the hatch).
  • Do not pull the plug from the socket - this may damage the control module.

In cars Bosch and Siemens a forced interruption may reset the program settings. After restarting, select the mode again.

Washing machine LG with function AI DD always erases longer than specified. Is this the norm?

Yes, in cars with artificial intelligence (for example, LG FH6G1BCH2N) washing time can be automatically adjusted depending on:

  • Weight and type of fabric (sensors analyze the load).
  • Pollution level (determined by the turbidity sensor).
  • Temperatures of water in the water supply.

This is not a breakdown, but a feature of the work. If the difference with the stated time exceeds 30–40%, check the program settings - options may be activated Extra Rinse or Steam.
