Siemens dishwasher repair

Siemens dishwasher repair Siemens dishwashers are rightfully considered the most reliable. Quality parts plus excellent European assembly speak for themselves. However, this technique also requires repair. For most, a Siemens machine breaks down after 10 years or more, for some it may break down after a couple of months, but sooner or later it happens. How to repair Siemens dishwashers, what typical malfunctions occur in such dishwashers and whether it is possible to repair such equipment with your own hands, we will talk about this further.

Slow water supply and program freezing

According to data provided by service center specialists, Siemens dishwashers break down approximately 2 times less often than most budget and middle-class dishwasher brands. But Siemens still has some weak points. The most common problem is considered to be a malfunction, the main symptom of which is an extremely slow water supply and a periodically freezing dishwashing program, and the choice of program does not matter.

After some time, if the operation of the Siemens dishwasher continues, it will begin to display error E16, first occasionally, then more and more often. Ultimately, the machine will freeze completely, displaying error E16, and restarting will do nothing. What kind of breakdowns give rise to such symptoms? In essence, there is only one reason - the flow filter located in front of the fill valve.

Dishwashers European-assembled Siemens are designed for well-purified water with a minimum amount of impurities and suspended matter; their flow filters have a mesh with very small cells, which quickly becomes clogged when connected to a Russian water supply. To make the standard filter less clogged with dirt, you need to install another cleaning flow filter in front of it, and you need to remove both filters and wash them every 6 months.

Important! Experienced craftsmen, in addition to the additional filter, use another protective measure - they immediately change the standard filter. Recently, the manufacturer began to produce spare parts (including filters) specifically for Eastern Europe and Russia. It is precisely these filters that experts recommend installing when installing a machine yourself.

How to restore normal water supply to the dishwasher and prevent systematic freezing of the washing program with your own hands, without the help of a specialist? Siemens dishwasher repair

We reliably shut off the water flowing into the Siemens dishwasher.
We pull out the dishwasher so that there is reliable access to the inlet hose and its connection points. But do everything carefully so as not to tear out or crush the hoses and power cord.
Disconnect the hose along with the additional filter (if any) from the tee tap.
We unscrew the hose on the other side of the dishwasher and unscrew the standard filter from there.
Wipe the filter area with a dry, clean, lint-free cloth.
Pour lemon juice (100 g per 2 liters of water) into a small basin, pour warm water and soak both filters in this solution for 2-3 hours, then rinse and clean the filters from dirt and install them in place along with the hose.

Reduced washing quality

Also, quite often, after 1-1.5 years of operation, Siemens dishwashers begin to wash dishes worse. At the same time, the user adds the same detergent in the same amount to the cuvette, also stacks the dishes, selects the same washing program, in general, does everything as normal, but the quality of the wash becomes worse and worse. What is the cause of this annoying symptom? Strictly speaking, there are several reasons:

weak water pressure;
The detergent supply valve does not work well;
the nozzles of the rotating rocker arm are clogged.

Low water pressure occurs due to the fact that the inlet valve flow filter is clogged.

We have already discussed how to clean it with your own hands in the previous paragraph. Therefore, we immediately move on to the second reason - the detergent supply valve is not working well.

The essence of the problem is as follows. Finish powder or tablets for the dishwasher are placed in a special compartment, from where they are removed gradually during the implementation of the washing program. If this compartment is not cleaned and rinsed, the valve will eventually begin to open and close poorly, and its holes will become clogged with dried remnants of semi-dissolved powder. As a result, during washing, the powder or tablet will dissolve less well, and the quality of dishwashing will only worsen.

The problem is easily solved. You should make it a rule to wipe the detergent dispenser with a clean, dry cloth after each dishwashing. and then this problem will never visit you again. It would also be a good idea to use it periodically dishwasher cleaning products, which will prevent the accumulation of dirt in the dishwasher and remove all unpleasant odors.

The same thing happens with clogged rocker nozzles on a Siemens dishwasher.They must be cleaned once every 4-6 months, otherwise there will be no water pressure and the quality of washing will decrease. The injectors can be cleaned with a regular toothpick. Push it one by one into all the holes of the rocker arm, and then run a cold wash with dishwasher cleaner.

Problems with waste water disposal

We have considered the malfunctions associated with reduced washing quality, now we move on to problems with the removal of waste water. Why can water drain poorly from Siemens dishwashers? There are two main reasons: either there is a blockage somewhere in the drain path, or the pump has failed. We have discussed cleaning the dishwasher from clogs several times. This process is well described, for example, in the article Replacing and cleaning the dishwasher filter, we will not dwell on this point again. Siemens dishwasher pump

In general, the dishwasher, like any equipment, must be looked after; if this is not done, quick breakdowns are inevitable. A pump breakdown is a much more unpredictable situation. You can take good care of your Siemens dishwasher and still end up in a similar situation. How to replace a dishwasher pump You can read it yourself in the article of the same name, it’s not too difficult. But first you need to check the pump, maybe it’s not broken, but is it an electrical or electronic issue?

We arm ourselves with an ohmmeter and remove the front bottom panel of the Siemens dishwasher.
We disconnect the machine from the network and tilt it back a little (about 20⁰).
Now we can clearly see the pump mounted on the body of the circulation pump, set the ohmmeter to the minimum value, and then install its probes on the contacts of the pump.
We measure the value, if the number is in the range of 1000-1500 - everything is fine, if less, the pump is faulty.

For your information! A faulty pump is not necessarily “silent” while the dishwasher is running. It may hum, but at the same time not fulfill its function of pumping water.

Problems with indicators, emergency shutdown

Another problem with modern models of Siemens dishwashers is spontaneous emergency shutdown, which is preceded by flashing indicators and sound signals. Moreover, if the dishwasher is unplugged and then turned on again, the problem repeats, it is completely impossible to wash the dishes. What is the cause of the problem?

Unfortunately, this breakdown is one of those that cannot be repaired with your own hands. If your car is under warranty, experts advise getting rid of it altogether. The fact is that such symptoms indicate a breakdown of the control module.

At Siemens, it is much more difficult to repair the control unit, since the board is sealed by the manufacturer into a non-separable module. For this reason, only some craftsmen undertake to repair it; mostly everyone refuses and suggests replacing the entire unit, which is almost half the cost of a new dishwasher. If the car is old, then it is better not to repair it at all if such a breakdown occurs, although it is up to you to decide.

In conclusion, we note that Siemens dishwashers are very, very reliable; their malfunctions are largely due to improper use by users. Therefore, if you take care of your dishwasher, it is very likely that it will work for many years without any problems.
