Error E06 in Hansa washing machine

Error E06 in Hansa washing machine Error E06, issued by the Hans washing machine, indicates problems with draining waste liquid from the tank. The interpretation of the code is quite vague; in order to determine the source of the malfunction, it is necessary to diagnose the washing machine. Experienced technicians can indicate what caused the E06 error in the Hans washing machine in a few minutes. If you want to return the machine to operation with your own hands, you will have to spend more time, partially disassemble the machine and check every element of the drainage system. Let's figure out how to do this.

Cipher meaning

The self-diagnosis system of Hansa automatic machines, when a problem is detected, automatically displays a failure code on the display. Error E06 indicates that the water was not drained from the tank into the sewerage system within the allotted time. Pumping out the waste liquid occurs too slowly or does not start at all. The machine, having failed to drain the water the first time, will start a second drain cycle. If during this time the liquid is not removed from the system, the machine will issue code E06. Draining may be difficult due to:

pump failure or severe clogging;
clogged drain filter;
breakage of the pump supply wiring;
breakdown of the pressure switch;
clogging of the drain hose or its incorrect connection;
problems with the main control unit.

To eliminate error E06, you need to check all elements of the CMA that can cause this code.

You need to try to fix the problem from the simplest: first, check the garbage filter, inspect the drain hose, and then you can move on to diagnosing the drain pump and level sensor.It is better not to start repairing the control board without having experience working with electronics. Incorrect actions can completely damage the control module.

The drain system is clogged

Checking the condition of the garbage filter is very easy. Even a housewife can do this kind of work with her own hands. The filter is a plastic spiral, on the surface of which debris that gets into the drain system settles. The filter element is located at the bottom of the washing machine, in the right corner, behind a small door. To remove the garbage filter from the housing, you must:

turn off the power to the machine;
disconnect equipment from house communications;
Using a thin screwdriver, pry the door open, release the locking latches and open it;
cover the floor under the SMA with rags or place a container to collect water;
Holding the protruding part of the filter, begin to unscrew the part from left to right.

What to do with the element once it is in your hands? It is necessary to clean off all adhered dirt, remove any tangled hair and rinse the coil under running water. If the part is too dirty, it is better to pre-soak the filter element in water with the addition of citric acid.

After cleaning the garbage filter, it is a good idea to inspect the hole where it is inserted. The plaque must be washed off the walls. Then use a flashlight and shine it into the cavity. Carefully inspect the pump impeller. Hair often gets wrapped around it, which prevents the impeller from rotating and triggers code E06. It would be a good idea to inspect the drain hose. It may be kinked, or there may be a blockage in the tube. Cleaning the drain hose may help correct the situation.

Let's look at the pump

If cleaning the garbage filter does not help reset error E06, you will have to dig deeper. In some cases, the reason for the impossibility of removing water from the SMA tank lies in a failed drain pump or a broken pump wiring. You can inspect the drainage pump of the Hans washing machine through the missing bottom. For this:

disconnect the automatic machine from the power supply and communications;
cover the floor with rags;
place the machine on the back wall;

Before placing the washer on the floor, make sure there is no water in the drum and dispenser, otherwise it will leak.

disconnect the wiring from the drain pump;
connect a pre-prepared conductor with a plug to the pump;
make sure the created connection is reliable;
plug the cord directly into the electrical outlet;
monitor the situation. If the pump works, then there are no problems with drainage, and the reason will have to be looked for elsewhere - the control board or pressure switch.

You can also diagnose the pump using a multimeter. The tester probes are applied to the pump contacts. The device must be switched to resistance measurement mode. If the multimeter screen displays a value within 150-260 Ohms, then the part is working. A zero displayed on the tester display will indicate a short circuit. If the device produces a value greater than the standard value, the stator winding has broken. It is not advisable to repair the drain pump; it is better to purchase a new pump and replace the part.

There is another way to check the drain pump manually. How to diagnose:

remove the snail;
Turn the impeller with your finger; it should rotate intermittently, as the magnetic rotor moves jerkily;
try shaking the impeller across the axis to the left and right. If play is noted, the drain pump must be replaced;
Connect the motor to the electrical network using the power cord and socket. A working device will start working without making any extraneous noise.

You can buy a replacement drainage pump in specialized stores or order it online from reliable suppliers. You should select the pump by serial number. It is better to purchase components from the washing machine manufacturer, but you can also buy an analogue with similar characteristics, the same power and an identical seat.

We look at the water level sensor tube

If the situation cannot be corrected after a complete check of the drain system, it is recommended to inspect the pressure switch. The water level sensor sends signals to the “brain” of the machine about the degree of filling of the tank when filling and draining liquid.

If the pressure switch tube is clogged, contact with the control module is lost and the machine issues the familiar code E06.

You can check the level sensor like this:

turn off the power to the washing machine, disconnect it from communications;
remove the top cover of the unit by unscrewing the bolts securing it;
find the pressure switch - this is a small round box attached to the edge;
disconnect the wires leading to the sensor, remove the element from the housing;
Check the box and tube for defects or blockages.

To diagnose the sensor, you need to prepare a tube with a diameter similar to the pressure switch fitting. It connects to the pressure hose. Next you should blow into the tube. Two or three characteristic clicks will indicate that the contacts are actuated, which means the water level sensor is working. If the pressure switch does not make a sound, you will have to replace the part; repair will not help in this case.

If, after checking the pressure switch and cleaning the elements of the drain system, the washing machine still displays error E06, this is probably due to damage to the control board. It is better to invite a specialist to diagnose and repair the main control module.
