Hansa washing machine errors - what they mean and how to fix them

Error codes for SMA "Hansa". Hansa washing machines are excellent value for money, which is largely undervalued in our market. A special feature of these washing machines is the presence of two series, which differ technologically. And the display of faults in them is implemented differently. Therefore, the information is presented in two sections and summarized in tables for convenience.

Do you wash by hand?

Oh yes! No

Checking the tachometer

To try to fix the problem yourself: you need to correctly determine the cause of the problem. In most cases, error E21 is caused by a faulty tachometer. It is located directly on the engine and is “responsible” for the intensity of the drum revolutions. To get to the sensor, you will have to perform a number of actions.

Disconnect the machine from the power supply, sewerage and turn off the water supply tap.
Provide free access to the unit by moving it away from the wall or pulling it out of the cabinet.
Remove the back wall by unscrewing the corresponding screws with a Phillips screwdriver.
Remove the drive belt by pulling the rubber towards you while rotating the pulley.
Mark the conductors connected to the motor and disconnect them.

Important! Do not neglect markings or photographs so that during reassembly you do not mix up the contacts and perform correct installation.

Unscrew the bolts holding the engine and, loosening the engine, remove it from the housing.
Inspect the Hall sensor attached to the motor, checking the fixing force and the existing contacts. If any of the above are loose, you need to tighten the terminals, restore connections and return to their original position.

When there are no doubts about the contacts and fastenings, we test the tachogenerator for performance. To do this, it is enough to measure the existing resistance or voltage. First of all, we check the resistance force by opening the connectors and applying the multimeter probes to the contacts. If the display shows numbers within 60-70 Ohms, then the sensor is working. Another option is to measure the current production. We switch the device to a new indicator and attach the connectors, turning the engine. The optimal value is about 0.2 Volts.

A negative result requires replacement of the tachometer. It is important not to make a mistake here, so we remove the removed part and take it to the store for clarity. The device is installed back in a similar way.

Fault codes for HANSA PC series washing machines

In this series, the company produces two lines of washing machines: Comfort and Optimum. They differ in their set of functions and technical characteristics. The Optimum SMA does not have a display, and therefore information about the presence of errors occurs by illuminating the indicator light. In the figure below, the buttons with which fault codes are generated are marked with letters.

Control Panel

And here is a summary table for the entire line of PC washing machines.

Testing the thermal switch

If the result is positive, we leave the tachogenerator alone and continue to search for a breakdown of the Hans washing machine in the thermal switch. We again disconnect the machine from all communications, open the back cover and pay attention to the heating element. Disconnect the wires going to the external thermostat and loosen the retaining fasteners. Then we remove the water heater and take out the thermistor located inside.

Now we check the sensor for sufficient resistance:

If the available numbers are far from normal, you will have to replace the thermistor. To repair the sensor, you cannot just purchase a new copy, focusing on the serial number and model of the washing machine. Subsequent installation of the device and assembly of the machine will not cause any trouble: we simply proceed in the reverse order.

Successfully passed tests with a thermostat and tachogenerator indicate one thing: the control board is to blame for the E21 error that appears on the display. Here it is better not to experiment with DIY repairs, since the control module is too sensitive to third-party manipulations. Any wrong movement will lead to large-scale consequences with an expensive call to the service center. It is recommended not to try to fix the breakdown yourself, but to immediately call a qualified specialist.

How to get rid of the problem?

Don't immediately think about the worst. The control board breaks down extremely rarely; more often it is much easier to fix the “E10” error. In most cases, problems that can be resolved without repairs and lengthy diagnostics lead to failure. To make a “diagnosis” of Hansa and begin “treatment”, you will have to consistently check all possible breakdowns, starting from the simplest.

First of all, we check whether the error will repeat a second time. It is possible that there was a short-term technical glitch. To diagnose, just restart the machine and assess the condition of the equipment. We proceed like this:

If, after rebooting, Hansa did not generate an error at the same point in the cycle, then the failure was short-lived and does not require further diagnostics. Otherwise, you will have to immediately determine the cause of E10. You cannot continue trying to reset the code - you can aggravate the situation, even to the point of death.

The second step is to check the electrical network. Ideally, you should call a qualified electrician, but if you have experience, you can do it yourself. The main thing is to follow safety precautions and be extremely careful. If the power supply to the house is unstable and voltage surges occur constantly, then it is better to include a stabilizer in the circuit.

The third stage is checking the outlet and extension cord. Here, signs of a breakdown will be obvious: burnt out wiring, melted insulation, a burning smell, dark spots. If there are no suspicious “symptoms”, we move on to practice: we connect a working device to the electrical network or remove the “adapter” from the circuit. Works? Then the problem is found. If checking the electrical network does not reveal any problems, then the problem is an internal failure - the control board has failed. Here, amateurish work is dangerous: you need to contact a service center for professional diagnostics and repairs.
