My Bosch washer isn’t spinning

What if your Bosch washing machine isn’t spinning the clothes after the washing cycle?

The operation reasons

The Bosch washing machine typically won’t spin due to the wrong program chosen or the violation of simple operation rules. Are you running the washing cycles for delicate clothes and linen? They are initially designed with no spin cycle at all or with the spin cycle performed at the lowest speed. So no wonder if the Silk cycle will provide you with too wet clothes.

The second reason is the spin function turned off. The user may be selecting some spin speed and turn off the spin cycle by mistake. In fact, that is not a malfunction. Just wait till the end of the washing cycle and turn on the very spin function. The picture indicator is a spiral on Bosch washers.

The third reason lies in the wrong load put into the drum while ignoring the designed load size and drum size. One can not overload the drum, as well as underload. If your coat comes out wet – you have overloaded the small drum. If your organza blinds come out wet – you have underloaded the washer.

Take care while sorting clothes, not only color, but also the number and weight matters. Add something heavy or tennis balls to small things.

Technical faults causing spin problems in the washing machine

If the above reasons are not the case, you need to look for some malfunction. The causes may be as follows:

  • the faulty tachometer;
  • the faulty pressure switch;
  • the broken motor;
  • the clogged filter or pump;
  • the malfunctioning electronic module.

Due to the specific design features of Bosch washing machines, the drive belt fails over time. The belt of the washer undergoes slight stretching and can no longer provide a stable transmission. Due to the stretched belt the tachometer provides the electronic module with some weird spin speed data. “Weird” means the data differs from the intended. As a result, the electronic module fails just before the spin cycle, and the latter won’t start. The solution is to tighten or replace the belt.

After replacing the belt, the electronic module of the Bosch washing machine returns to normal work.

How to detect and troobleshoot the Bosch washing machine failure

Isn’t the Bosch washing machine spinning or activating the actual cycle of the washing process? Then you need to start with removing and checking the lint filter. Cleaning the washing machine filter is a must for the maintenance of any automatic washer. If it is neglected, it may result into drain problems and the activation of the spin cycle.

Next you need to disassemble the washing machine. Pull out the detergent drawer, place the washer on the left side and remove the bottom part. Get to the drain pipe and pump from below. Unscrew the clamps, remove the branch pipe and check it. Remove the pump, disassemble it and check the impeller first of all. After that, take a multimeter and check the resistance of the pump.

If the pump is all right, you need to check the motor right there, because you can get to it through the bottom relatively easily. Remove the brushes, if they are intact, and check the resistance of the motor winding.

After checking the motor, get down to the tachometer of the Bosch washing machine. The Hall sensor is located on the very housing of the washing machine motor. We can get to it also through the bottom. Remove it and check the resistance. If the sensor is faulty, it needs to be replaced.

Now check the pressure switch.

  1. Remove the screws securing the top cover of the Bosch washing machine.
  2. Remove the top cover.
  3. Carefully clean and blow the tube of the pressure switch and then check the resistance. If the malfunction is obvious, the element replacement is required.

Worst of all, if at last your troubleshooting work brings you to the control module of the Bosch washing machine. You need to find out which of the triacs is out of order. It is very difficult, almost impossible to do this with little experience in handling electronics. You’ll have to contact a qualified repairman.

How to extend the service life of your washing machine

Any appliance tends to break from time to time. Indeed, nothing is eternal. Still, oddly enough, a user can make a Bosch washing machine work longer than usual with no breakages.

The basic rules of using the washing machine:

  • Do not shove your clothes into the drum of the washing machine without checking its pockets and removing all foreign items. They can get into the tub and then clog it.
  • Stick to the average load. It is very important not to overload the washer, as well as not to start it in vain. For example, if your Bosch washing machine load size is 6 kg, let your optimal washing cycle be done with 2.5-5 kg load. It will enable the motor and the drive mechanism to serve as long as possible.
  • Start the washing machine at least once a month. If the washer will stand idle for some reason for a long time, its rubber seals will be ruined, and the user will have to pay for the repair work.
  • Do not put too much detergent into the detergent drawer. Note the washing machine will not appreciate your generosity. On the contrary, the excess powder will clog the pipes and the tubes of the pressure switch causing some damage.

Never use the detergent standards stated on the package. There are often cases, when the manufacturer increases the standards. Of course, the company pursues its business interests.

  • If possible, get a voltage regulator and further connect the washing machine to the mains only using it. This measure will keep the sensitive electronics of the washer safe.
  • After each washing cycle, remember to take care of the washing machine: wipe the rubber gasket and the detergent drawer with a cloth. Keep the hatch and the detergent drawer wide open for them to dry. Unscrew the garbage filter and drain the remaining water to avoid stagnation.
