Bosch dishwasher error code e25 informs the user that there is garbage in the dishwasher system. Namely: drain pump problems or the drain pipe blockage.
The problem with the pump can be connected with the impeller locking, caused by foreign objects. They could get into the drain pump while washing dishes.
Foreign objects:
- bones;
- peel from fruits and vegetables;
- pieces of napkins;
- toothpicks;
- shards of dishes.
Even if you clean the plates of food residues carefully, anyway the fatty filter clogging may occur. If the dishwasher is not cleaned periodically by special means, the fat from the appliances accumulates in the drain system. As a result, it clogs the drainage filter, hoses, and branch pipes.
The drain pump itself may also fail. Here you can read the description of the E25 error code, by Bosch itself.
How to fix error code E25
Filter
The first thing to do when an e25 error occurs is to check the filter inside the dishwasher and the pump impeller. If the code appeared during the dishwashing, prepare for the fact that there may be too much water on the floor.
- Disconnect the drain hose from the dishwasher body and put it down into the container to drain the remaining water.
- Pull out the bottom basket for the dishes.
- After accessing the drain filter, unscrew it, as well as the metal mesh that is located behind it.
- Rinse the filter under running water.
- The impeller of the drain pump is placed behind the filter.
- Try to turn the impeller with your fingers or any subject. If the impeller does not turn, then something is blocking it.
Be careful, a small sharp piece of dishes or glass can block the impeller and injure you.
Drain pump
If cleaning the filter did not help, or you were unable to free the impeller of the pump from clogging, then proceed to disassemble the dishwasher. To do this, you need to turn the dishwasher upside down and gain access to the unit of circulation and drainage of water. In some models of dishwashers, you can access the drain pump by removing the panel under the door. To remove the pump, it must be rotated clockwise.
Also, do not be superfluous, check the pump with a multimeter. For this multimeter probes attach to the terminals of the pump. The value on the multimeter should be in the range of 100-300 Ohms. If the Ohms value is greater or less, the drain pump is out of order. In the video above you can see the whole process of extracting the pump. But if you need a new pump, then you can buy it on Amazon or Partmaster.co.uk
Drain Hose
Also additionally, check and clean the drain hose that is attached to the circulating pump.
There is also a universally popular method of cleaning the drain hose.
You will need a wet and dry vacuum cleaner to apply this method. Remove the drain hose of the dishwasher from the siphon and connect it to the vacuum cleaner. The diameters of the hoses of the dishwasher and the vacuum cleaner may not match, but you need to try to put them together manually. Then turn on the vacuum cleaner at full capacity for pumping out water from the dishwasher. The vacuum cleaner should get all the water from the dishwasher. You will be surprised that besides the water you will see a lot of unseen debris. Add some more liters of clean water to the dishwasher forcibly and repeat this action to best effect. Such a hose cleaning do not require a long disassembly of the dishwasher. As a result, the appliance will not bother you for a long time.
Many additional components and accessories that are out of order can be purchased on the official website of Bosch.
User tips: how to get rid of the error code E25
Sometimes the Bosch dishwasher error code e25 may occur due to a float. It is located in the water heating section on the left behind the panel.
This problem may occur after several years of operation of the dishwasher. This float (“ball”) often gets stuck. After the system has drained the heated water, this ball does not return to its place. So the dishwasher fails to identify the working condition and won’t drain any dirty water. As a result, the E25 error code is displayed.
For troubleshooting, add the KILL ROCK-BIG W liquid into the dishwasher. Start the standard operating cycle. Repeat it up to 5 times. Then proceed with 3 cycles using the HG SERVICE ENGINEER powder. Use special cleaning agents once a month to avoid the problem in the future.
Some users say you can shake out the stuck ball if you pull out the dishwasher and shake it. Well, this advice is troublesome and hard to try.
