Spin Belt

Top loading Bosch washers are fitted with a belt that runs the transmission. The belt could be the source of problem if the Bosch washer ceases to agitate. How do you determine if theBosch washing machines drive belt needs to be replaced:

  1. Disconnect your Bosch’s power source before you begin.
  2. You’ll need to cut off the clamps that hold the drive belt in place. That is attached to the drive motor is the drive belt. To access the drive belt, you’ll have to remove the back panel or cabinet.
  3. Once you have removed it check the belt for signs of fraying, cracking, burning, or any other damages.
  4. You can replace your belt using Bosch replacement belt If you experience any issues.

Pump Belt

Some top load Bosch washers use a belt to operate the drain pump. The belt is a typical V-shaped belt that is attached to the pulley of the drain pump. A pulley with an idler can be used to tighten the belt. If you experience a burning rubber smell from the inside of your Bosch washer, inspect the pump belt. How do you determine whether the belt on aBosch washing machine is in need of replacing:

  1. Disconnect your Bosch washer from its power source and open the cabinet in your washer.
  2. Find and then remove the pump belt in order to inspect it. The pump belt will be tied to the pulley of the motor that drives it. To take it off, you’ll need to take off the clamps that hold it in the place.
  3. Examine your pump visually for signs of wear, burning cracks, fraying or other damage.
  4. It is necessary to replace the Bosch pump belt If your belt shows any of these indicators.

Motor Pulley

The drive motor uses an incline to rotate the pump and drive belts. Motor pulleys are constructed of metal or synthetic materials in order to ensure the best contact with belts. If the pulley wears out or rusty, it might cause excess friction, and then overheat or damage the belt, causing a burning smell. How to examine the motor pulley of the Bosch washing machine:

  1. Before beginning this inspection, disconnect the plug on your Bosch washer.
  2. Locate and remove the motor pulley in order to closely inspect it. To achieve this, you’ll have to remove the cabinet, and then remove any belts that are attached to it.
  3. Take a look at your motor’s pulley for any accumulations of grease, dirt, or other materials, as well as for signs of damage, wear, or burning. If your pulley is damaged or wear, you’ll have to replace it with a Bosch replacement.

Drain Pump

The drain pump of a Bosch washer machine is used to remove the water out of the wash tub before and during the spin. The pump may be motor driven, belt driven, driven, or possess an electric motor. A burning smell coming from the Bosch washing machine either during or after the spin cycle might signal that the drain motor is stuck, which prevents it from rotating. The burning smell is typically caused by the movement of the belt onto the pulley for the pump in belt-driven models. Models with an electric drain pump will smell more like an electrical motor. How do you check the drain pump on aBosch washer?

  1. Disconnect the appliance’s power supply , and then pull out the front or cabinet. Once you have found the pump, check the connections and hoses that are flowing out of it to identify the source. R
  2. eplace the connector or hose in case there are any problems.
  3. If the leak originates directly from the pump then you’ll need a Bosch replacement pump.

Idler Pulley wheel and Idler Pulley Arm

Top load Bosch washers use an idler pulley for tensioning the drive belt or pump. If the idler pulley becomes blocked or the idler arm fails to move freely, then the correct tension for the belt will not be obtained and friction or belt slippage will happen, causing the belt to overheat, causing an unpleasant smell. How to inspect the wheel of the idler pulley & arm of a Bosch washing-machine:

  1. Examine and locate your idler pulley wheel and arm. You are looking for any indications of wear, damage cracks, burning, or cracks.
  2. To examine the pulley, you’ll have to take off the drive belt from the pulley. To take off the belt, turn your idler pulley to the drum in order to decrease the tension, and then allow it to slip it off.
  3. To make sure that the operation is smooth, inspect the wheel of the pulley. It should not wobble or sway.
  4. You’ll need to replace the idler pulley wheel/arm when you find any issues with the previous checks.

Direct Drive Motor Couplement

Top load Bosch washers use direct drive motor couplings instead belts to transfer power from motor to the transmission. The drive coupling is made comprised of two drive forks, as well as the rubber coupling. It joins the motor to the transmission. One drive fork connects to the drive motor shaft and the other to the transmission’s input shaft. The rubber coupling between the drive forks absorbs the force and stops them from breaking when the motor shaft rotates. The coupling will wear out over time. At some point, the drive forks may slide and release the smell of burning. How to examine the direct drive motor coupling of a Bosch washing-machine’s direct drive motor coupling

  1. Similar to other inspections you should verify that your Bosch is not connected to the power source.
  2. For a thorough inspection of the condition of your Bosch washer, you’ll be required to disengage the coupling. It is necessary to remove the whole cabinet of the washer. In accordance with the model you will also have to take out the motor or drain pump.
  3. Examine your motor coupling for damage, cracks or wear. Also, look for burning.
  4. If you have any issues in your motor coupling, you will need a Bosch replacement direct drive motor coupling.

Clutch Assembly

Certain top-load Bosch washers feature a clutch assembly that drives the washing basket through the spin cycle. If your Bosch washer is emitting a burning smell, it could be caused by the worn-out clutch. The machine could also make the sound of scraping loudly during the spin process. A worn clutch can also be evident by the presence of shavings and brake dust that are found under the Bosch washing machines. How to examine the clutch assembly inside aBosch washer:

  1. Once the appliance is removed from the power source, you can open the cabinet of the Bosch washer to see the clutch assembly.
  2. Remove the clutch assembly of your Bosch appliance to inspect it in detail. It’s located under the tub’s outer surface that is connected to the basket drive unit. Depending on your model you might need to take off the drive motor as well as the transmission to gain access to it.
  3. Check your clutch assembly for indications of burns, wear and fraying or other signs.
  4. If you observe any of the above signs then you’ll need an Bosch replacement clutch assembly.

Glide and Spring

Some Bosch washing machine models use spring and glide for their drive motors for belt tensioning. Typically, the drive motor has a pivot mount to the base frame and an internal spring that provides the tension. In order for the motor to slide across the Bosch washer base frames, a nylon or lubricated glide is attached to the bottom. This will allow the belts of the pump and drive belts to slide a bit when the motor starts to turn on. It functions as an automatic clutch. If the belt does not glide freely, the belts could get overheated and emit a smoky smell. How to check the slide and spring on a Bosch washing machine.

  1. Before starting, unplug the Bosch washer.
  2. Remove or remove the front panel of the washer to discover the spring(s) or glide(s). The springs for the drive motor and glides are normally placed on top of the frame and can be found by taking off the front panel.
  3. Verify that the motor’s pivot point is properly The springs are not stretched and ensure that the motor’s surface is free of dirt or corrosion.
  4. Check the glide(s) to look for signs of burning, wear, or damage. Lubricate them as needed.
  5. Bosch replacement springs might be required if you discover any problems or broken parts during these checks.

Drive motor

The main drive motor of most Bosch washers is used control the mechanical functions of the washer, like spin, tumble, and agitation. It may also be used to control the drain pump. If a problem or defect occurs with one component of the motor driven components, it can cause the drive motor to overheat causing burnt smell. If the problem is serious the motor could overheat to the point of failure. A failing drive motor can be identified by hearing a loud, ringing sound at the time it starts. How do you check the drive motor of a Bosch washing machine:

  1. After verifying that you removed the plug from your washer, take it out of the cabinet of the Bosch appliance.
  2. Take the drive motor off to test it. There will be several wires connected to it. You can remove them by pulling on the connectors that are made of metal and not the wires themselves.
  3. Test the connection to ground as well as the continuity of the motor. For both of these tests, your multimeter must be set to Rx1.
  4. To verify continuity, connect the probes to the terminals of the motor. You should receive a reading near or even zero. You can test for a grounded connection by placing one probe on the terminal, and then touching the other one to its housing made of metal. This should not produce any readings.
  5. If your multi-meter readings do not match those above, you’ll require a Bosch replacement drive motor.
