Bosch maintenance, error codes and after-sales service in Belgium: the practical guide
A well-maintained Bosch appliance lasts a long time. Here are the simple jobs you can do yourself, the programmes to know, the most common error codes with what you can check, then everything about warranty, after-sales service and spare parts in Belgium.
- Cleaning : filter, seals, drum, descaling, pyrolysis
- Error codes : E15, E24, E25 and what you can check
- Warranties : 2 years statutory, motor and tub 10 years (registration required)
- Bosch after-sales service : 02 475 70 01, parts available for up to 15 years
Washing machines
Programmes to know
- Eco 40-60 : the reference programme on the energy label. It washes mixed cotton at 40 or 60 °C using as little energy as possible, but it takes a long time (3 h 33 on the WAN2827AFR). That's normal: it heats less and agitates for longer.
- Express 15/30 min : for a small, lightly soiled load.
- Drum cleaning : run it empty, roughly once a month. The WUU28T69FR reminds you automatically.
- Adding laundry : the Start/Pause button lets you add a forgotten sock at the start of a cycle.
Routine maintenance
- The drain filter, behind the bottom-right flap: empty and rinse it every two to three months. Have a mop and a dish ready, as there is always a little water left.
- The door seal : wipe it after each wash and remove any small objects caught in it. Leave the door and detergent drawer ajar to prevent odours.
- The detergent drawer : it pulls out completely; rinse it under hot water.
- Limescale : dose your detergent according to your water hardness (often high in Wallonia) and run the cleaning programme regularly.
Heat pump tumble dryers
- The lint filter on the door: empty it after every drying cycle. This is the most important step for keeping drying times short.
- Easy Clean Filter (condenser filter, at the bottom): rinse regularly, as indicated by the light.
- The condensation tank : empty it whenever the light comes on, or replace it with a drain connection.
The dishwasher
- The filters at the bottom of the drum: unscrew, rinse under the tap, once a month.
- Regenerating salt and rinse aid : even with all-in-one tablets, salt protects the machine from limescale. Set your water hardness in the menu (the manual explains how).
- The spray arms : if a hole is blocked, remove the arm and clear it with a cocktail stick.
- A hot empty cycle with a cleaning product every two or three months.
Fridges and freezers
- No Frost : no defrosting needed. Simply clean the inside with warm water and white vinegar two to three times a year.
- LowFrost and 4-star freezer : defrost when the layer of frost exceeds a few millimetres.
- The door seals : clean them and check they close properly (a sheet of paper caught in the door should not slide out easily).
- The rear grille on freestanding models: dust it once a year.
- The settings : 4°C in the fridge and -18°C in the freezer are the right benchmarks.
The oven, hob and cooker hood
- Pyrolysis : remove shelves and drip trays (unless the manual says they are pyrolytic-safe), run the cycle, then wipe away the ash once cool. A pyrolysis cycle every one to two months is enough for family use.
- CleanCoating and EcoClean : heat the empty oven for a few minutes after cooking something greasy. Never use a caustic cleaner on these walls.
- Induction hob : a soft cloth and a ceramic hob cleaner. Scrape off sugary spills straight away with a scraper.
- Hood : metal grease filters can go in the dishwasher about once a month. For recirculating models, replace the charcoal filters as stated in the manual.
Common error codes
| Code | Device | What it means | What you can check |
|---|---|---|---|
| E15 | Dishwasher | Water protection activated (water in the base) | Switch off the appliance and the tap, look for a leak, check the detergent dose (too much foam). If it recurs: contact after-sales service. |
| E24 | Dishwasher | Difficult drainage | Filters clean, hose not kinked, siphon not blocked. |
| E25 | Dishwasher | Drain pump blocked | Remove the filters and carefully take out any debris (glass, stone) in front of the pump. |
| E16 to E28 | Washing machine | Code range (door, water, drainage…) | Door firmly closed, drain filter clean. Bosch details each code on its online help page. |
Codes taken from the official Bosch Belgium help pages. Depending on the model, the display may vary: check the manual. Never dismantle an appliance while it is powered on.
Warranty and after-sales service in Belgium
- Statutory conformity guarantee : 2 years, provided by the seller.

- Free extended warranties (MyBosch registration): SilentPowerDrive motor on washing machines 10 years, dishwasher tub 10 years against corrosion. AquaStop: water damage cover for the life of the appliance.

Contact Bosch after-sales service
The Bosch Belgium service can be reached on 02 475 70 01 (Monday to Friday, 8:30am to 5pm) and offers online booking. Keep to hand the E-Nr and the FD of the rating plate (inside the door of the dishwasher or washing machine, inside the fridge, on the oven frame). Out-of-warranty prices are published: call-out and diagnosis fee of €99.99, and all-inclusive repair caps depending on the age of the appliance.
Spare parts
Bosch sells its genuine parts online, by E-Nr number. For large appliances made since 2023, essential parts remain available for up to 15 years. Cooker hood filters, baskets and shelves: these accessories are easy to order.
Home Connect and remote diagnosis
If your appliance is connected, after-sales service can, with your permission, check its status remotely via Home Connect and arrive with the right part. A real time-saver.
Maintenance schedule at a glance
| Frequency | To do |
|---|---|
| After every use | Tumble dryer lint filter, washing machine door seal, hob wiped |
| Every month | Dishwasher filters, cooker hood grease filters, drum cleaning programme |
| Every 1 to 2 months | Oven pyrolysis, depending on use |
| Every 2 to 3 months | Washing machine drain filter, dishwasher empty maintenance cycle |
| 2 to 3 times a year | Fridge interior cleaning, door seal check |
| Once a year | Dusting the rear grille of freestanding fridges |
| According to the manual | Charcoal filters for recirculating cooker hoods, defrosting a freezer without No Frost |
These frequencies are guidelines for family use. A household running two washes a day or cooking a lot of fried food will need to go more often; a single-person household can space them out. If in doubt, your appliance's manual remains the reference.
Take a photo of the rating plate on the day of installation and register the appliance on MyBosch straight away. The day you need it, you'll save valuable time. For a French model bought from us, ask us for the procedure.

Frequently asked questions
What does error code E15 mean on a Bosch dishwasher?
The AquaStop water protection system has triggered: water has been detected in the base. Switch off the appliance and the tap, and check there is no visible leak or excessive foam. If the code returns, call the aftersales service.
What should you do with an E24 or E25 code?
These are drainage problems. Clean the filters at the bottom of the tub, check that the drain hose isn't kinked and that the siphon isn't blocked. On E25, the pump may be blocked by debris, which should be removed carefully.
How much does a Bosch repair cost outside warranty?
Bosch Belgium announces a call-out and diagnosis fee of 99,99 €, labour packages of 134,99 to 204,99 € and all-inclusive repair caps of 359,99 to 479,99 € depending on the age of the appliance. Every repair is guaranteed for 24 months.
How do I register my Bosch appliance?
Create a MyBosch account on the Bosch website and enter the E-Nr and FD numbers from the rating plate. This is essential for the extended warranties (motor, tub).
Should I use descaling tablets in a washing machine?
In Belgium, the water is often hard. A Drum Clean programme, empty, at high temperature, once a month is enough in most cases. Follow the manual for recommended products.
