Bosch washing machine does not drain or spin

It can be confusing and frustrating when your Bosch washing machine suddenly stops spinning or draining. These problems can cause you to have a pile of wet clothes after interrupting your laundry routine.

The first step in solving your washing machine’s malfunction is figuring out why it’s not working properly. Determining the source of the issue can assist you in getting your machine back up and running, whether it’s a small blockage or a more significant mechanical issue.

We’ll look at the typical causes of these issues in this post and walk you through the steps to solving them.

What caused the breakdown?

When a Bosch washing machine has been in use for longer than five years, this kind of "symptom" can point to almost any kind of malfunction. To find the malfunction, you will need to examine each component of the washing machine separately. In case the washing machine is still relatively new, the drainage system should be given more importance.

Often, a blockage in the drainage system prevents Bosch washing machines from spinning and draining.

Thus, if you only use the Bosch washing machine for a year or two, check the drain system’s components for blockages first. Examining the trash filter is the simplest method. The "home assistant" might not be able to begin spinning and draining because there might be a sock or handkerchief stuck in it.

You will need to empty the "stuck" machine’s water yourself first. Set up a large, low basin to catch the liquid. The washing machine should then be tilted back, and the trash filter area should be covered by a container. Dry rags should be used to cover the area of the floor surrounding the appliance.

Next, remove the machine’s garbage filter by unscrewing it. Not fully, but just by a half turn. The basin will start to fill with water. After that, completely remove the "trash can" plug and check for obstructions in both it and the drain hole. You can consider the issue resolved if you discover a misplaced sock or glove.

The cause is different if the drain hole and trash filter are clean. Check for obstructions by feeling the machine’s drain hose. Verifying that there isn’t a traffic bottleneck in the sewer pipe is also preferable. Water from the sink and bathtub drains poorly when the riser is clogged.

The next step is to examine each of the Bosch washing machine’s primary components individually:

• drive belt;
• pump;
• Hall sensor;
• electric motor;
• motor brushes;
• control module.

The Bosch washing machine might not want to spin or drain water if one of these components breaks. In contemporary models with a display, the error code associated with the malfunction will be shown. It is advised to begin checking from simple to complex if the washing machine is "silent." First, we will instruct you on what to do.

Drive mechanism

The engine and the drive mechanism are the two weak points of inexpensive Bosch washing machines. These units’ quality and design both need a lot of improvement. Based on statistical data, one out of every fourteen Bosch washing machines experiences issues related to the motor, Hall sensor, or drive belt starting in the second year of operation.

The quickest route to the belt. It is therefore examined initially. The following will be the sequence of events:

• de-energize the automatic machine;
• close the shut-off valve responsible for the water supply;
• move the washing machine away from the wall and furniture to have access to its body from all sides;
• unscrew the screws securing the back panel of the machine, remove the wall;
• inspect the drive mechanism.

You can see the drum and motor pulleys as well as the drive belt stretched between them as soon as you remove the washing machine’s back panel. It has flown off the "wheels" and is lying beneath the machine if there is no rubber. In this instance, the reason the washing machine stopped functioning will become evident.

After the belt has been fastened, rotate the drum pulley. It ought to spin vigorously. Verify the rubber’s tension as well. It will be necessary to replace a worn-out, sagging belt with a new one.

The motor cannot spin the drum at the necessary speed if the drive belt is not properly tensioned.

The machine will not be able to begin squeezing because of a drive belt issue. The intellect will note the mistake and provide an incorrect answer. Consequently, mid-cycle freezing will occur in the washing machine.

On forums, artisans suggest adjusting the pulley’s position by tightening the motor mount rather than replacing the stretched belt. Such movements will cause the rubber to stretch and the "wheel" to move a few millimeters. Nevertheless, this approach will only address the issue temporarily—a few months—before the same problems recur.

The most common cause of a Bosch washing machine not spinning or draining is a straightforward problem like an uneven load, a clogged drain hose, or a blocked filter. Gaining an understanding of these typical issues will enable you to diagnose and fix the problem on your own, saving you both money and effort.

The drain pump is to blame

The drain pump is the next item on the inspection list. Bosch washing machines also have a pump, which has a limited lifespan and may eventually break down. In particular, washing machines that have been in use for longer than five years are affected by this issue.

The Bosch washing machine’s drain pump may catch fire. Also, if debris builds up inside the pump, normal operation is terminated. Additionally, hair coiled around the impeller blades slows down the element’s operation.

Bosch washing machine pumps typically malfunction when the apparatus is situated more than two meters away from the sewage system. In this instance, the pump’s load surpasses the upper limit of tolerance, resulting in swift component damage. As a result, be especially mindful of the washing machine’s distance from communications when installing and connecting it.

To examine the washing machine’s drain pump:

• disconnect the machine from the mains;
• close the shut-off valve responsible for the water supply to the washing machine;
• disconnect the device from the water supply and sewerage;
• pull out the drain filter;
• shine a flashlight into the hole formed after removing the filter – there you can see the impeller of the drain pump;
• clean the drain hole from debris and dirt, remove hair wound around the impeller blades;
• remove the powder receptacle from the washing machine;
• lay the machine on its right side, having first laid a blanket on the floor;
• remove the washing machine tray;
• take a photo of how the wires are connected to the pump;
• disconnect all contacts from the pump;
• loosen the clamp that secures the drain pipe to the pump;
• disconnect the pipe from the pump;
• remove the pump from the washing machine;
• disassemble the pump body, having dealt with the latches;
• inspect the "insides" of the part, make sure that the mechanism and all the rubber bands are intact;
• clean the pump from the dirt accumulated inside.

Cleaning the pump can assist in resolving the issue if it was severely clogged. As a result, assemble the pump, install it, and run a test cycle after clearing the debris.

Do not rush to replace the part even if it appears from the outside that there are no issues with the pump. Using a multimeter to verify the pump’s operation is also essential. It might have burned out.

Put the probes on the pump contacts after turning the multimeter to the voltmeter mode. The tester display will show a zero or a one if the part is out of order. It is not possible to repair the pump; a new element must be purchased and installed.

Let"s check the motor

The Bosch washing machine’s bottom must be opened to inspect the electric motor, Hall sensor, and brushes. Since the drain pump was previously inspected, the "home assistant" is resting correctly, on its side. To perform additional diagnostics, you must:

• take a photo of the wiring diagram to the motor;
• disconnect the power supply wiring from the motor;
• unscrew the screws that secure the part;
• remove the motor from the washing machine housing.

Press down on the machine, slide it back, and then slowly pull it down and in your direction to extract the electric motor.

Examine the Hall sensor first. It’s a tiny ring. A multimeter is used to test the component. It will be necessary to replace the tachogenerator if a breakdown is found.

Next, take the motor brushes off and give them a look. Install new graphite rods if the old ones are worn out. Even if one of the electric brushes is still in good condition, they must be replaced in pairs.

Using a multimeter to measure the motor winding’s resistance is the next step in the diagnostic process. Rebuilding the motor is not advised if a flaw is discovered. The purchase and installation of a new engine is more convenient.

There are a few common reasons why your Bosch washing machine might not be spinning or draining. The most common causes are a malfunctioning pump, a clogged pump filter, or a blocked drain hose. You may avoid wasting time or even paying a repair bill by first inspecting these parts.

The machine’s control board or door lock system may occasionally be malfunctioning, preventing the machine from starting the spin cycle. It may be time to seek professional assistance if you have eliminated all basic problems with your machine and it is still not functioning.

You can assist in preventing these problems from occurring in the future by routinely cleaning the filter and making sure the drain hose is clear. Maintaining your washing machine properly is essential to keeping it in good working order.
