Bosch Dishwasher Does Not Drain

click fraud protection

If your Bosch dishwasher does not draw water, do not rush to blame around the manufacturer. Perhaps it's not a breakdown, but an easily removable problem. Where to look for the cause, read below.

Sometimes users encounter such problems: loading dishes in a tank and starting a dishwasher, they hear a buzz. Water intake does not occur. We will understand how to fix the damage. . ContentsHow to understand that the cause of the problem in the intake capacity of the dishwasher? Look at the panel, the indicator may blink there or the error code E3 will be lit on the display - this is how the system writes that there is no water.

If there is no water in the car, there may be a minor problem. Removing it yourself is easy, for this check:

  1. The presence of water in the faucet. Perhaps the water supply was turned off, so the dishwasher responds accordingly. Wait until it is restored.
  2. Density of closing the door. For the sake of safety, the technician will not start washing until the door is closed and locked at the electronic level. If you can’t close the camera tightly, you should check the condition of the lock on the door.

  3. Twist the stop valve. It is located on the water pipe. It happens that it accidentally overlap.
  4. Inlet hose. If it is transferred, pinched, clogged, then the water in the dishwasher does not pass.

Have you done all the manipulations, but the water indicator still flashes? So, the reason is more serious damage. What could happen:

  1. Intake valve defective. After receiving the signal from the electronic module, the membrane on the valve opens, allowing water to flow. After reaching the desired level, the valve closes. You need to check the part and make sure it is in good condition.
  2. The pressure switch does not work. The sensor informs the module about the amount of water in the tank. If the pressure switch sends incorrect readings, then the module does not give a command to dial.
  3. There was a problem with the Aquastop system. If this is the case, then the machine does not supply water due to the blockage of Aquastop. The cause may be leakage or malfunction of the float sensor.
  4. The control module has broken or burned. Perhaps one of his triacs out of order. Requires diagnostics and repair.

Hard water in the pipes contributes to the formation of scale and clogging. There could be a filter that stands between the inlet hose and the valve.

Solving problems with a set of water in the ASM

If you have already checked all that is possible, but the water still does not pour into the system, then you need to inspect the individual parts. Start by cleaning the filter and the hose:

  • shut off the shut-off valve;
  • unscrew the inlet hose;
  • behind it is a mesh filter;
  • wash the parts under pressure from a tap; a small brush can be used to clean the hose.

At the same time you can check the rest of the details.

Filling valve

If no water is supplied to the Bosch dishwasher, the intake valve is inspected first. Visually look for any mechanical damage on the surface of the part. To check the electronics, you need to apply a voltage to the element, which will show whether the membrane opens or not.

The electrical part is called by a multimeter, the resistance is measured and a verdict is made.

The intake valve cannot be repaired. It will take a complete replacement of the element, which can be carried out independently. Disconnect the wiring and loosen the screw securing the part. The main thing - pick up the original spare part for the brand and number of your car.

Door hopper

Until the door of the camera is tightly closed, the machine will not start. What if the door does not close to the end? Check:

  1. Compactor. When it is deformed or climbs out of the seat, it can interfere with the normal closure.
  2. Latch. A broken lock will not bring the door "to the click", and the system will not start.
  3. Placement of baskets and other camera elements. Perhaps something is preventing the door from closing.
  4. Installation PMM.Check the placement of the machine using the building level.

How to install a new lock on the door:

  • open the door of the bunker;
  • remove the bolts around the perimeter of the inside;
  • remove the outer panel;
  • disconnect the wiring;
  • remove the fastening screws and remove the lock;
  • install new item and connect wiring.
  • reassemble in the reverse order.

We do not recommend replacing individual broken parts, trying to repair the old lock. It does not guarantee long-term operation.

System "Aquastop"

First of all, check whether there is no water in the pan. When a leakage occurs, the protection float pops up, presses the switch and the water intake is blocked. When the Aquastop is activated in the dishwasher, the fault code E15 may appear on the display.

What to do:

  • unscrew the hose from the body( if you have a mechanical "Aquastop");
  • look at the valve inside: if it is tightly pressed against the walls of the hose, then you need to replace the protection;
  • for this, disconnect the old hose and install a new one.

If you have an electromagnetic device, then additionally connect the wire to the sensor.

level sensor Incorrect pressostat readings can also cause a lack of water. How to replace the level sensor, we wrote in one of the articles. Most often, the device is a plastic box that is attached to a circulating pump. Checking his mechanics is very simple - blow into the pressure tube. If you hear clicks, the pressure switch is normal.

The electrician is called a multimeter.

Electronic module

Modern Bosch dishwashers are equipped with a control module. He manages all the processes in the car and gives commands to the nodes. For example, drain the water from the bunker or start a water intake. If one of the triacs of the board burns, then some part ceases to function. Therefore, the module requires a flashing or replacement.

Only a specialist can diagnose and repair an electronic board.

You can handle the details in the Bosch dishwasher by yourself. Sometimes the reasons for the lack of water lie in a small blockage, so before calling the master, make sure that the breakdown really exists.
