In basic malfunctions you figured out. Now we need to find out how to fix the breakdowns in the Siemens dishwasher.

How to repair a dishwasher

Let's give a detailed instruction on how to start and fix the dishwasher. Let's start with the most common malfunction.

No water recruitment

The quality of water in the water supply leaves much to be desired. Dishwashers of overseas assembly are not designed for such impurities in water, so the strainer before the valve quickly clogs. To reduce the number of blockages, install a flow filter in front of the mesh. Periodically clean both elements, then the water will enter the machine normally.

How to clean the system:

  1. Shut off the water supply.
  2. Disconnect the filler hose from the PMM housing.
  3. Pull out the strainer and rinse under running water.
  4. If the contaminants are strongly eaten, leave the filter to soak in a solution of water and citric acid (in 2 L dilute 100 g).
  5. Install the elements in the reverse order.

No draining of water

If there are problems with the drainage system, the water will not go away after washing, it may happen that the overflow occurs. Also blockage causes the program to stop. For example, you start the car, water is dialed, but the car wash does not start.

How to disassemble and clean the system:

  • Unplug the machine from the power supply, shut off the water.
  • Open the hopper door, remove all the trays and baskets for the dishes.
  • From below, unscrew the drain filter.

  • Clean it from the blockage by rinsing with running water.
  • How to unlock the pump? Remove sponge of water in the area of ​​the pump with a sponge.
  • Push the pump cover until it clicks, pull it toward you.

  • Inspect the pump for blockage. Clean with gloves, as the pump could clog up glass shards.

To avoid blockages, clean the dishes of leftover food before washing. Also use special cleaning agents.

The cause of the breakdown can be not only in the blockage, but also in the breakdown of the pump. How to check it:

  • Remove the lower front panel of the machine. To do this, unscrew the fastening 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 working, if the number on the screen is 1000-1500. In other cases, you need a replacement.

Bad dishwashing

Over time, when using the Siemens machine, the quality of washing is reduced. You do the usual loading, pour the detergent, but the dishes on the output are not too clean. Why this happens:

  1. Too little water pressure in the water supply.
  2. The valve for supplying the product is clogged.
  3. Clogged holes on the rocker arms.

What to do:

  1. Wait until the normal water supply resumes.
  2. Check the filter mesh for blockage.
  3. After each cycle, clean the detergent drawer. Over time, the powder accumulates, dries up on the walls, build-ups block the passage of the valve. Simply wipe the tray with a dry cloth after washing dishes.
  4. In the dishwasher, there are two rocker arms for spraying water - the upper and lower. Unscrew the top and remove it from the seat. Lower the blade pull up and remove from the body. Clean the blade holes with a toothpick under running water.

Do not forget to care for the technique, then the breakdown will happen less often.

The dishwasher shuts down

If the indicators flash randomly on the panel, an emergency shutdown occurs, the cause is in the control module. To diagnose the breakdown of the module and even more to repair it - only the master can. The structure of the Siemens dishwasher complicates this task.

The manufacturer has concluded a control board in a soldered unit. Most specialists refuse to repair it.

The module is one of the most expensive parts of the dishwasher. Therefore, if the machine is old, it is more profitable to buy a new technique than to change the module.

Carry out an independent repair of equipment only after the warranty period is over. Use cleaning agents, clean the filters in a timely manner. Then you do not have to deal with the malfunctions and repair the breakdowns at home.
