Identifying the fault: How to know if the pump is damaged? Early warning signs: ⚠️ The squeezing phase does not start. – The machine stops in the middle of the program. ⚠️ Buzzing or whistling noise During water drainage ⚠️ The drain hose is hot to the touch. – A sign of friction in the pump motor ⚠️ A strong smell of burnt plastic While the machine is running Initial checks before replacing the pump: Cleaning the filter: Open the bottom panel (front right corner) and remove any coins, socks, or foreign objects that may be stuck. Checking the drain pipe: Make sure the hose is not bent or clogged. Manual operation: If you hear a humming sound but the water doesn't drain, the pump is probably defective. Locating the model sticker: Where to find the model number on the washing machine? Sticker location: (I.e. On the inside of the door – Open the machine door and look at the inner right lip (I.e. On the back of the machine – In the upper back (requires machine indentation) (I.e. On the left side – In rare cases, under the side panel Essential details on the sticker: �� E-No. (Model number) – For example: WAV28M73EX/01 �� FD (Serial number) – starts with FD followed by digits �� Product Number – 12-digit long code �� Pro tip: Take a picture of the sticker on your phone before ordering – this way you can send it for quick verification if a question arises. Installation: Is this your task or for a technician? Complexity level: High ⚙️⚙️⚙️ Replacing the pump requires partial disassembly of the machine, disconnection of electrical and water connections, and precise installation with new seals. We strongly recommend using a certified technician from the official service. For the following reasons: ✔️ Comprehensive diagnosis – Make sure that the fault is indeed due to the pump and not the control card or water meter sensor. ✔️ Special tools – A special Torx wrench and voltage tester are required. ✔️ Tightness test – Improper installation may cause water leakage and electrical short circuit. ✔️ Responsibility for work – A certified technician gives a 3-month warranty on the installation For those with technical experience: If you decide to install it yourself, make sure the machine is unplugged. And from the waters, route an emergency drain through the lower pipe, and document the wiring order in a photograph before dismantling.

How do I know that the pump is original and not an imitation? Every original Bosch/Siemens pump comes with Hologram label on the packaging and a serial number engraved on the plastic body. In addition, the electrical and water connections are marked with standard colors (blue for water, red for electrical). Non-original pumps often lack these markings, and their plastic tends to be harder and more brittle. 2. Is it possible to repair an existing pump instead of replacing it? In most cases – no. Modern pumps of this type are built as a sealed unit, and dismantling them risks damaging the internal seals. In our experience in the service laboratories, customer repair attempts have ended within two weeks in complete failure of the pump. If you have heard an unusual noise or seen an E18 code – the recommendation is immediate replacement. 3. How long does it take to replace the pump? An experienced technician from the official service completes the replacement in 45-60 minutes, including a leak test and running a trial cycle. Independent installation for experienced people may take 90-120 minutes, provided you have the right tools (torque wrenches, pliers, resistance measuring device). 4. Does the pump come with a gasket kit? The pump itself comes with original rubber seals pre-installed on the connection ports. Yet, it is important to purchase Diphon kit 00425075 Separately if you want to reduce noise and vibrations. This kit includes 4 bushings and 4 screws that support the pump and prevent noise transmission to the machine casing. 5. How do I prevent repeated clogging of the pump? ✅ Emptying pockets before washing – Coins and pins are the most common cause of pump damage ✅ Using bags for delicate laundry – Small socks and underwear may slip through the drum ✅ Cleaning the filter once a month – Open the bottom panel and wash the filter under the tap. ✅ Running a cleaning program – Once a quarter, run an empty cycle at 90°C with washing machine detergent (from Bosch) 6. What do you do if the machine still doesn't drain after replacing the pump? In such a situation, you should check the Water level gauge sensor (Pressure Switch) – A thin rubber tube that comes out of the drum to the sensor may become clogged with soap residue and prevent the machine from “realizing” that it is full of water. In addition, check the Electronic command card – Power surges or water leaks can damage it. A qualified technician will check both of these components during a service visit. 7. Is there a warranty on the pump? 90 day labor warranty – This means that if the problem returns within 3 months, the technician will return at no additional cost. It is important to keep the purchase invoice and service certificate. �� Remember: Using an original part is not just a matter of quality – it is also about maintaining the integrity of advanced systems such as EcoSilence Drive and-ActiveWater Plus Which come with an extended 10-year motor warranty. Don't risk your warranty and performance with an unapproved part.
