Regular washing machine maintenance extends appliance lifespan by 4 to 6 years according to ADEME and prevents 70 percent of common breakdowns. This guide details the complete maintenance routine to apply monthly, quarterly and annually, as well as wear signs to monitor to anticipate technical intervention.
Why regularly maintain a washing machine
A washing machine runs on average 4 to 5 cycles per week in a French household, or 240 cycles per year according to the GfK 2025 study. Each cycle leaves detergent residue, limescale and textile fibers that accumulate in the drum, seal, filter and pump. Without maintenance, this residue reduces washing performance, generates bad odors and accelerates component wear.
Preventive maintenance extends the average lifespan of a washing machine from 8 to 14 years according to ADEME (2024 data). On a new appliance at 480 euros or a best refurbished washing machine at 349 euros, this extension represents real savings. The most frequent breakdowns (bad odors, minor leaks, reduced spin) are avoidable with proper maintenance.
Areas to maintain
Five areas concentrate washing machine maintenance needs:
- The drum, in direct contact with laundry and wash water
- The door seal, which retains moisture and promotes mold
- The detergent tray, often clogged with product residue
- The drain filter, which captures coins, hair and fibers
- The drain hose and pump, downstream of the water circuit
Each area requires a different frequency and maintenance method, detailed below.
Monthly maintenance routine
This routine takes 30 minutes per month and covers essential operations. It can be scheduled on the same day each month to avoid being forgotten.
Drum cleaning
Drum cleaning is performed via an empty cycle at 90 degrees Celsius with a descaling product. Two methods depending on budget and preference:
- White vinegar: pour 250 ml into the detergent tray, run a cotton 90 degree empty cycle. Cost: about 0.30 euros. Effective against light limescale and odors.
- Specific washing machine descaler: sachet or bottle dosed for one cycle, poured according to manufacturer instructions. Cost: 2 to 5 euros per dose. More concentrated, recommended for very hard water areas.
Hot water dissolves limescale, detergent residue and eliminates bacteria responsible for odors. This operation maintains washing performance and prevents dark spots on light laundry.
Door seal cleaning
The rubber door seal retains water after each cycle, which promotes black mold in its lower fold. Seal cleaning is done with:
- A clean sponge soaked in pure white vinegar
- Meticulous wiping of the inner fold, lifting the rubber
- Rinsing with clean water using a cloth
- Complete drying, door left ajar after use
This step takes 5 minutes per month. Mold established for more than 6 months resists vinegar and requires the use of an anti mold product or seal replacement (cost: 30 to 60 euros for the part, 80 to 150 euros with installation).
Detergent tray cleaning
The removable detergent tray is cleaned by completely removing it (consult the appliance manual), rinsing it with hot water and brushing residue with an old toothbrush. The softener and pre wash compartments are the most clogged. Recommended frequency: once a month.
Quarterly maintenance: the drain filter
The drain filter captures small objects (coins, buttons, clips) and textile fibers before they reach the pump. It is located behind a hatch at the bottom front of the appliance. Frequency: every 3 months or as soon as a weak spin appears.
Filter cleaning procedure
- Unplug the washing machine
- Place a flat basin and cloths in front of the hatch (1 to 2 liters of water may flow out)
- Open the hatch and slowly unscrew the filter
- Empty the contents, rinse the filter under running water
- Check that no object is obstructing the housing
- Screw back firmly and close the hatch
A clogged filter is the primary cause of drain errors displayed on modern washing machines. Quarterly cleaning avoids 90 percent of these alerts according to Murfy 2025 data.
Annual or semi annual descaling depending on water hardness
Descaling frequency depends directly on local water hardness, measured in French degrees (TH). To know the hardness in your municipality, consult your water supplier’s website.
| Water hardness | TH | Descaling frequency |
|---|---|---|
| Very soft | 0-7 TH | Every 18 to 24 months |
| Medium | 7-22 TH | Every 12 months |
| Hard | 22-32 TH | Every 6 months |
| Very hard | more than 32 TH | Every 4 to 6 months |
The hardest water zones in France are the Paris region, the North, Burgundy and parts of Provence (over 30 TH). In these zones, semi annual descaling is mandatory to preserve the heating element and motor.
Descaling method
Descaling uses the same products as monthly drum cleaning, but at reinforced doses:
- White vinegar: 500 ml poured directly into the empty drum
- Citric acid: 100 to 150 g dissolved in 1 liter of hot water, poured into the drum
- Concentrated commercial descaler: according to manufacturer dosage (often 2 doses for descaling)
Run a cotton 90 degree empty cycle. The acidic water dissolves limescale fixed on the heating element, the main degradation point of a poorly maintained washing machine. A limescale clogged heating element consumes up to 30 percent more electricity according to ADEME (2024 study).
Wear signs to monitor
Beyond preventive maintenance, certain signs announce imminent breakdown and require rapid intervention. Ignoring them worsens the breakdown and increases repair cost.
Mechanical signs
- Excessive vibrations during spin: indicates drum imbalance, worn shock absorbers or poorly distributed load. Repair cost: 80 to 250 euros if shock absorbers.
- Clicking or friction noises: worn drum bearings. Expensive repair (250 to 400 euros), often the appliance replacement threshold.
- Drum that turns poorly during washing: distended or broken belt (20 to 40 euros for the part, 80 to 150 euros installed).
Electrical signs
- Water not heating: heating element broken or clogged with limescale. Cost: 80 to 180 euros replacement.
- Cycle interrupted without reason: faulty electronic board. High cost, sometimes over 300 euros.
- Recurring error display: consult the code in the manual or Murfy database to identify the cause.
On an older washing machine or a refurbished washing machine, preventive intervention at the first signs significantly extends lifespan. On a new appliance still under warranty, contact the manufacturer before any handling.
Practical tips to extend lifespan
Beyond scheduled maintenance, several daily habits extend washing machine lifespan:
- Do not overload the drum (respect the indicated capacity, generally 5 to 9 kg)
- Empty pockets before each wash to avoid clogging the filter
- Dose detergent correctly (overdosing clogs the appliance and reduces efficiency)
- Leave the door ajar after each cycle to dry the drum
- Run an empty cycle at 60 degrees Celsius if laundry is very dirty or after a particular wash
As reminded in our comparison where to buy a refurbished washing machine, serious refurbishment players systematically replace wear parts (seals, belts, heating element), which extends appliance lifespan. A well maintained appliance after refurbishment lasts on average 8 to 12 years according to the Syndicat de l’Electroreconditionnement 2025 data.
Common mistakes to avoid
- Using bleach to clean the drum: damages seals and internal coating
- Skipping door seal cleaning: 1st cause of persistent bad odors
- Descaling too often (every month): acid prematurely degrades seals
- Ignoring a clicking noise for several cycles: worsens bearing breakage
- Excessive detergent dose: clogs the appliance, counterproductive
Frequently asked questions
How often should a washing machine be maintained?
Complete washing machine maintenance is performed monthly for drum and seal cleaning, every 3 months for the drain filter, and every 6 to 12 months for descaling depending on local water hardness. Average usage of 4 to 5 cycles per week requires this rhythm to reach the 12 to 15 year lifespan of a well maintained appliance.
How to clean a washing machine drum?
The drum is cleaned by running an empty cycle at 90 degrees Celsius with 250 ml of white vinegar in the detergent tray, or with a specific washing machine descaler. This operation eliminates limescale, detergent residue and bacteria responsible for bad odors. Recommended frequency is once a month.
How to descale a washing machine without chemicals?
Chemical free descaling is done with 200 to 300 ml of white vinegar poured into the detergent tray, followed by an empty cycle at 90 degrees Celsius. Baking soda (100 g) can complement the action by absorbing odors. This method costs less than 1 euro per descaling and remains effective when repeated every 6 months in hard water areas.
What to do if the washing machine smells bad despite maintenance?
A persistent odor after standard maintenance generally indicates a clogged drain filter (to be cleaned manually), a siphoned drain hose or a deeply moldy door seal. The seal is cleaned with a sponge soaked in white vinegar, focusing on the lower fold. If the problem persists after these operations, intervention by a specialist technician such as Murfy’s may be required to check the pump and condenser.
How much does annual washing machine maintenance cost?
Annual washing machine maintenance fully performed independently costs between 10 and 25 euros per year: white vinegar (5 to 10 euros), optional commercial descaling products (10 to 20 euros), possibly a seal to replace every 5 to 7 years (30 to 60 euros per part). A technician intervention for professional descaling costs 80 to 130 euros, justified only in case of advanced breakdown or on a very clogged appliance.
