There is no trouble-free technique - even premium representatives fail. There are malfunctions in the Siemens dishwasher. According to consumers, they break twice less often than other brands.
What to do when a breakdown occurs? Pay attention to the work of the Siemens PMM, diagnose the problem and fix it yourself. How to do this, read below.
Error codes for Siemens dishwashers are compiled and described in detail in a separate article.
Causes of damage to Siemens dishwashers
The main causes of damage to the Siemens dishwasher:
- The machine does not work, the display does not light, or the program freezes. The reason may be the lack of voltage at the outlet. If you press the button and the program is not selected, the contacts may have burned out.
How to connect a car? It is necessary to disassemble the panel, clean or replace the contacts. - PMM is not collecting water. Check for water in the water supply immediately. Then inspect the inlet system: the cause may be a blockage in the inlet hose, flow filter, intake valve.
- Why is a dishwasher washing dishes poorly? Perhaps the water supply valve is clogged, then the water pressure is too small, so the dishes are poorly washed. The nozzles on the beam that spray water can also become clogged. It is necessary to clean the system for normal water intake.
- The equipment turned on as usual, but water intake does not occur, the washing does not start. The reason is the door is not tightly closed.
How to adjust the door? It is enough to tighten the loops of its fastening so that the lock normally passes into the hole. - When problems arise with the drain, the entire drain system is checked: filter, pump, hose. Details are cleared of a blockage. If the pump breaks, then the part changes.
- If the machine draws water, but the washing does not start, the problem is in the circulation pump. Need diagnostics and repair.
- The dishwasher includes an emergency shutdown. The reason is the control module - in this case, it is better to contact the wizard.
- Water does not heat up. Need to check the heater, thermistor. The heater rings, in case of malfunction it is replaced. The thermistor must also be replaced.
- The dishwasher does not dry the dishes. If your model has a drying function, then the cause of the breakdown is in the drying fan or its wiring.
You figured out the main faults. Now you need to figure out how to fix breakdowns in the Siemens dishwasher.
How to repair a dishwasher
We give detailed instructions on how to start and repair the dishwasher. Let's start with the most common malfunction.
No water intake
The quality of the water in the water supply leaves much to be desired. Dishwashers of an overseas assembly are not designed for such impurities in water, so the filter mesh in front of the valve is quickly clogged. To reduce clogging, install a flow filter in front of the mesh. Periodically clean both elements, then water will enter the machine normally.
How to clean the system:
- Shut off the water supply.
- Disconnect the inlet hose from the PMM body.
- Remove the filter screen and rinse under running water.
- If the stains have become too full, leave the filter to soak in a solution of water and citric acid (dissolve 100 g in 2 l).
- Install items in reverse order.
No draining water
If there are problems with the drainage system, the water will not leave after washing, overflow may occur. A blockage also causes the program to stop. For example, you start the car, water is collected, but the washing does not start.
How to disassemble and clean the system:
- Unplug the machine, turn off the water.
- Open the hopper door, remove all trays and baskets for dishes.
- Unscrew the drain filter from below.
- Clean it from obstruction by rinsing with running water.
- How to unlock the pump? Use a sponge to remove any remaining water in the pump area.
- Press the pump cover until it clicks, pull it towards you.
- Inspect the pump for blockage. Clean with gloves, as the pump could become clogged with broken glass.
To avoid blockages, clean dishes from food debris before washing. Also use special cleaning products.
The cause of the breakdown can be not only a blockage, but also a breakdown of the pump. How to check it:
- Remove the bottom front panel of the machine. To do this, unscrew the fixing screws.
- Lay the machine on its side or tilt it back.
- It is necessary to measure the resistance at the contacts of the pump.
- Attach the ohmmeter probes to the pump contacts.
- The device is serviceable if the number on the screen is 1000-1500. In other cases, a replacement is needed.
Poor dishwashing
Over time, when using the Siemens machine, the quality of the sink decreases. You do the usual loading, pour detergent, but the dishes at the outlet are not too clean. Why is this happening:
- The water supply is too weak.
- Closing valve
- Clogged holes on the rocker arms.
What to do:
- Wait until the normal water supply resumes.
- Check strainer for blockage.
- After each cycle, clean the detergent drawer. Over time, the powder accumulates, dries on the walls, growths block the passage of the valve. Just wipe the tray with a dry cloth after washing the dishes.
- In the dishwasher there are two rocker arms for spraying water - the upper and lower. Unscrew the top and remove it from the seat. Pull the lower blade up and out of the housing. Clean the holes of the blades with a toothpick under running water.
Do not forget to look after the equipment, then breakdowns will happen less often.
The dishwasher shuts off
If the indicators blink randomly on the panel, an emergency shutdown occurs, the reason is in the control module. Diagnose the breakdown of the module and even more so repair it - only the master can do. The structure of the Siemens dishwasher complicates this task.
The manufacturer enclosed the control board in a soldered unit. Most specialists refuse to repair it.
The module is one of the most expensive parts of a dishwasher. Therefore, if the car is old, it is more profitable to buy new equipment than to change the module.
Carry out an independent repair of equipment only after the warranty period. Use cleaning products, clean the filters in a timely manner. Then you do not have to deal with malfunctions and repair damage at home.
