Bosch Washing Machine Problems & Troubleshooting

Bosch Washing Machine Problems

Things will go wrong if you are unaware of the Bosch washing machine problems and don’t know how to fix them.

Problems are to be expected if your washer is old. But, if your washing machine is new and giving you trouble, it could be a simple problem that you can easily fix at home.

Washer not spinning, water leakage, draining issues, making noise, and vibration troubles are the most common Bosch washing machine problems.

The Bosch washing machines are very appealing and attractive to consumers due to their top quality and various new technological features.

However, many homeowners are disappointed with Bosch washers as they have encountered various issues, resulting in huge repair costs.

List of Common Bosch Washing Machine Problems

Take a look at our list of the most common Bosch washing machine problems and how to troubleshoot them.

1. Bosch Washing Machine is Not Spinning

If your Bosch washing machine is not spinning properly, there could be a number of causes.

Possible causes:

  1. The load may be unbalanced.
  2. The pump filter may be dirty.
  3. The drain may be blocked.
  4. You may have selected the “no final spin” setting.

What to do if your washer is not spinning?

If the machine detects an unbalanced load, the spin cycle will run, or it will only run at a reduced speed.

You can add some towels to help even out the weight and avoid overfilling the drum. Also, check the feet of the machine and readjust them if not balanced.

The machine will not spin if the drain pump is dirty or blocked by an object.

Here is how to clean the drain pump:

  • Turn off the water tap and disconnect the appliance.
  • Open and remove the service flap and drain the water through the hose (Warning! The water may be boiling). Then, unscrew the pump cover.
  • Clean the interior of the residue, and the impeller should be able to rotate manually.
  • It will also not spin if any metal object like a coin is stuck in the drain hose. So, you need to check and clean the drain hose pipe. Check the hose connector too.

If the drive belt is slack on the pulleys, tighten it. If it is broken or won’t tighten, replace it.

The other causes of the spin failure include broken tub bearings, damaged stator assembly, drum bearings, and worn-out basket drives. Check and replace them accordingly.

If you are still unable to fix the issues, contact Bosch’s customer service department, which will assign a technician to resolve the matter.

2. Bosch Washing Machine Leaking

Another common problem with Bosch washers is leakage. It can be frustrating if you can’t figure out what is causing the leak. However, there could be a lot of factors for leaking that you need to investigate.

How should I check and fix the leakage?

  1. Check the drain pump and clear all the blockages. If it is cracked or damaged, you cannot repair it. Replacement is the only solution.
  2. Check the drum seals, water supply valves or hoses, water pump, and tub bearings as well. If you find them damaged or broken, replace them.
  3. Ensure that the door latch on the washer keeps the door closed during the wash cycle. If the door is not fully closed, the machine will leak water. Replace the broken door latch.
  4. Pouring too much detergent into the tub can also result in leakage. Furthermore, the poor quality detergent is also the culprit of this issue. Therefore, make sure to use an appropriate amount of detergent during the wash cycle.
  5. Make sure you are running your washer on a level surface. On an uneven surface, the machine will leak water. You can readjust the feet of your machine or move it to a level surface.

3. Bosch Washing Machine Not Draining

Many homeowners also reported Bosch washer draining problems.

In this situation, you will find leftovers in the tub that may annoy you. But there is no need to worry as it is not a severe problem. You can quickly fix it at home.

But how?

  • Once again, you need to check your washer’s drain pump because it is the most prevalent reason for various washing machine problems. Clear all the blockages or replace them if there is a leakage.
  • Also, check all the plumbing lines for any clogs or blockages. Clean them if there is a buildup. Finally, make sure to clean the filter regularly to avoid any debris formation. 
  • While putting the load in the machine, double check the clothes are not carrying any metal object, which may lead to blockage or cause damage to the tub.

4. Washing Machine Making Noise

The washer usually does make noise, but noticing a sudden increase in the noise indicates a problem.

How can I figure out and fix this issue?

  • If a metal object becomes lodged in the drum of your washer, it may make a grinding noise. If you find an object in the drum, clean it.
  • Make sure the drain pumps are not clogged with debris.
  • If your Bosch washer is brand new and making grinding and whining noises, it could be due to a faulty installation. Do not hesitate to contact the Bosch customer service department to send a repair person to look into this matter.
  • Worn drum and tub bearings, worn drive pulleys, malfunctioning water inlet valves, broken tub seals, and defective drive belts are some other reasons for loud noises.

5. Washing Machine Vibration Problem

The vibration problem in the washer may cause you to worry. But, it is not as severe as it looks. It is just another prevalent issue in washing machines.

Check out the following tips on how to detect and fix the vibration problem.

  • Ensure the machine is on a level surface. On an uneven surface, the shock absorbers will not function properly, which may cause vibration.
  • If the shock absorbers are damaged, the machine will generate excess vibration while running. Firstly check all the shock absorbers and ensure they are in the right place. After that, evaluate each of them for damage and wear. Replace the one that is worn out.
  • Suspension rods are also among the reasons for excessive vibration. Replace if damaged.
  • Other things to check for vibration causes include suspension springs, rear drum bearings, tub wear pads, balance rings, snubber rings, snubber pads, shipping bolts, and bolts kits. Replace them if they are damaged or malfunctioning.

Bosch Washing Machine Error Codes

The Bosch digital series machines may indicate an error code if the washer has a problem. A single letter followed by two numbers will be displayed on the digital display as the error code.

These error codes help you to determine where the problem is occurring within the machine. It is much easier to solve a problem once you have identified it.

So, it is imperative to understand the meaning of the error codes to resolve them.

So, check out the most common Bosch washing machine error codes and how to fix them.

Watch this step-by-step video guide on how to identify and fix the Bosch washer error codes:

One more common problem is the Bosch washer’s door lock issue.

Final Words:

In this guide, we have explored the five most common Bosch washing machine problems and how you can troubleshoot them at home. There are some issues that you can fix with a little tweak.

But, if the machine has a problem with the motor or cannot detect the reason for the failure, don’t try out experiments. Instead, give a call to the Bosch customer support department to advise you on the matter.

As technology advances, Bosch has introduced digital washers. These machines display the error codes on the screen, indicating which part is malfunctioning.

So, if you know the meaning of the error codes, it will be much easier for you to fix them.

    • Hi Jullie,

      Start the fill cycle after emptying the washer and moving it away from the wall. While the machine is filling with water, check for drops around the water supply hose connection at the rear of the device. Replace any old, severely corroded, or rusty hoses with new ones before turning off the water.

  1. The worst!! I have to replace the front load drum seal at least once a year. It tears at the bottom. Horrid design and an obvious flaw that has never been addressed.

    I will never buy a front load Bosch matching again.

  2. Why does my brand new Bosch washing machine take much longer to complete the cycle than it states on display board

    • Hi Mrs Jean,

      I hope you are doing great!
      This could be an indication of a clogged drain or vent line. Either way, this means that your laundry is taking longer than usual to dry. You should consult with your local plumber about the possible causes and their solutions.

  3. I have a top loader of 2006 that floods and over-fills.

    I had a breakdown in 2020 that was due to the motor brushes end of life start. The main control board was damaged but was replaced with a lot of hassle and refusal of repairs to help.

    I was saved by finding a service manual, vital to get part codes for PCB and brushes. you can get to the motor easily from one side I replaced the shock absorbers (2) but not the faulty display, huge cost and none available anywhere. I added 2 fuses to power lines to motor so failure won’t hurt the new control panel. There are many cables to different parts of the PCB so identify each one with a label tied on wire and numbers on old PCB, but actually an easy job to replace.

    There arose a problem as new PCB had a new switch not described and no instructions. I wrote to director in Germany asking for settings. magic a lady emailed simple settings for switch to suit my machine it worked fine.

    In 2021 fresh issues. A lot of noise suggest bearings both sides of drum failing. Floods overflowing also. I tracked that to seal failure both sides of drum, so filling never stops.

    I fitted new bearings next drive from motor ordered from Germany as I had part numbered got 2 kits drawings of assembly very helpful to decision to replace NB. The first drive-end replacement took a lot of courage, as each shaft end has a special seal, might fit 2 ways and no instructions in service manual or with bearing kits I found bearings straightforward as mounted in a special carrier plate with seal fitted to rum on highly smooth face of bearing carrier. I found codes moulded on new seal and fount instructions on the Danish makers website. No advice available from Bosch.

    After reassembly I found more problems, failure of pump-out pump and still flooding on fill at start.

    Replaced pump, requiring new position of Mount holes and improved pus-fit insulated connector as old plug appalling design. It now has a poly bag electric enclosure, as old cover won’t fit over new pump .

    I find drain pipe at drum has to be checked by removal, good thing, as there is a ball at base of tank and it’s a solid block of dissolved Person mineral. Had to flex and break away deposit all down hose flex to pump.

    All drain system works fine and drum much quieter at high speed spin.

    Problems to fix other bearing I have still to do.I’m going to cut a panel opening to reach the bearing without huge disassembly of rest of panel. Water floods over that side during fill stage. I’m making a 20 Cm diameter opening for access to rearing carrier.

    Meanwhile saw note here to check Prescott for fill level. It’s terminals sense twi levels of fill. They have chance ohm readings so the contacts have become damaged i.e. end of life. New Prescott on order from Germany awaited.

    I hope this sshows what CA go wrong, but actually, apart from hassle it’s going to work soon.

    which told me to try to repair it as no other good top loader is available, unless from Bosch in India.

    Repair after 16 years hasn’t been easy, I suppose it just reached design lifetime. It’s quality of design and manufacture outstanding, but Bosch have a terribl quality of support and service information kept utterly secret Company Policy.

    That lack of support makes repair a challenge for DIY.
