Error E25 in a Bosch dishwasher - what to do

Error E25 in a Bosch dishwasher is a fairly common malfunction in PMM operation that owners of this equipment encounter. But is it as scary as it may seem at first, and how can you eliminate it at home on your own?

What does code E25 mean?

Deciphering the error generated by the electronic control system on the PMM display is simple - this code signals the user that the pipe connected to the drain pump in the drainage system. In a number of PMM models, the base of the drain hose itself, which is connected to the pump, becomes clogged.

Causes of problems

Error code E25 can appear on the display most often due to the drainage system being clogged with food debris or debris, when the owners themselves neglect the basic rules of operation when working with the equipment. So, in the drain of the PMM system itself, a blockage can form from:

1. bones (even the smallest and softest meat/fish);
2. fruit seeds;
3. peels and napkins, as well as toothpicks;
4. fragments of broken dishes and so on.

And even if, before putting it into the system itself and starting the dishwasher’s wash cycle, you clean the dishes from food residues, this, as practice shows, may not be enough. The blockage of the pipes itself can occur due to the fact that they have not been cleared of accumulated fat for a long time. And, as a result, it can accumulate in the steam chamber and thereby create a traffic jam.

Respectively, the pump cannot pump out water in this case. And in this case, the only question arises - what to do? The only way out is to clean the pipes and remove the blockage.

Restoring the operation of the Bosch PMM

Before you begin directly to work, rule out a failure in the electronic system at the very beginning. In this case, the equipment may mistakenly display this code on the display screen. And to reset such an erroneous “action” of the machine, follow these steps:

1. Disconnect the equipment itself from the power supply system to ensure the safety of all work - compliance with safety rules has not been canceled.
2. Let the equipment stand for 15 minutes - this will allow you to reconfigure the system during the next startup and return the settings to the previous operating parameters.
3. Connect the system to the power supply - if this code appears on the display again, you will have to have the equipment professionally disassembled and clean the blockage.

If the reason is precisely the blockage and not a failure of the electronic settings - at the very beginning you remove the water that accumulates at the bottom of the dishwasher. But at the very beginning, so as not to electrocute you, be sure to de-energize it by disconnecting it from the power supply. And then proceed to these steps:

• Take out the basket with dirty and unwashed dishes and also remove the lowest trough so that it does not interfere with the cleaning process.
• Scoop out the remaining dirty water from the machine and carefully unscrew the filter cover without jerking.
• Next, remove the filter glass itself from the system.
• Inspect it and blot up excess moisture with a rag.
• Take long and preferably thin tweezers and carefully remove the flap covering the impeller of the nose.
• Inspect and remove the blockage itself and then check the operation of the impeller itself.

After cleaning, put all the parts back in their working places in the dishwasher. And if this does not help, you will have to clean either the drain hose itself or the branch pipe, reaching through the bottom of the machine.

After that, put it on the back wall, open the bottom, remove the panel and disconnect the wires. When the bottom is removed, the filling of the unit is visible. Having disconnected the formwork, clean it. There is a hose connected to the pump - disconnect it too, wash it completely. For this, it is worth using a special cable with a brush. And after cleaning, return all the parts to their place, connect the unit to the power supply.

In the event of a drain pump failure, much will depend on the nature and type of breakdown. If the impeller breaks, it is replaced with a new one. But if the winding itself burns out in the system, the pump should be replaced completely. Although, as many dishwasher owners and craftsmen note, if you do not have sufficient experience and knowledge in repairing equipment, it is better to call an experienced specialist. How to prevent clogging in the future? In this case, it is worth following a number of simple rules and recommendations:

Thoroughly clean the dishes after eating from food residues before placing them in the dishwasher chamber itself.

After each dishwashing, dishwashing cycle - make it a habit to clean the drain in the machine from food residues, fat accumulation.

1. Every six months, carry out a complete professional cleaning using both physical and chemical methods. So all parts should be cleaned manually and after installation, run the machine idle.
2. similar entries from this sectionUpon completion of cleaning, all parts are placed in their working places in the system in the PMM. And if this does not help, then you will have to clean either the drain system hose itself or the pipe, reaching through the bottom of the machine.
3. Having freed the PMM from any remaining dirt and water, carefully pull it out to a free, open place and be sure to disconnect it from the water supply and sewerage system.
