Service test and error codes for Hansa PA4510A520/PA4510B421 washing machines

Error table for CM Hansa PC series

Frequent malfunctions

Although the quality of Hans washing machines is excellent, they still have weak points, the presence of which can be judged by the occurrence of typical faults. Most often, owners of devices of this brand contact us about the following problems:

• Drain pump failure. The most common fault with Hansa machines.
• Dirty drain filter and pipes.
• Controller failure. The malfunction is manifested by spontaneous shutdown, failure to complete the selected washing programs, and rotation of the drum in one direction.
• Aqua Spray system failure.
• Temperature sensor short circuit.
• The machine freezes due to voltage surges.
• Worn brushes or bearings.

You can see the repair of the Hansa washing machine control unit in the following video.

SM Hans PA series error codes

In the photo, the buttons (light bulbs) that are used in decoding errors are indicated in Latin letters A, B, C, D. See the table for how to find out about a breakdown, focusing on the light bulbs:

Once you understand the reasons for the breakdown, you will understand why Hans’s washing machine displays an error code. In most cases, repairs can be done yourself.

Checking the operating modes of the washing machine using a service test

The check is performed in the following sequence:

1. Set the program selection switch to the position corresponding to the selected test (except “0”).
2. Press and release the START button.
3. Control the execution of selected operations.

Short service test

A shortened test procedure is provided to check the performance of the main functions of the SM during statistical tests on the production line. CT can also be used to quickly check the SM by service specialists.

To carry out the test, the washing machine must be connected to the water supply network with the ability to manually shut it off.

The procedure for launching a shortened ST is as follows:

• set the program switch to position 1 (see figure above);
• press and hold button 17 (START/STOP). At the same time, the programs are switched as follows: 1 (initial position) - 2 - 3 - 2 - 3. The switch is held in each position for at least 1 s;
• after this, indicator 18 (START/END) should blink;
• release button 17;
• alternately (with a delay of 1 s) move the program switch to the following positions: 16 - 15 - 14 - 13 - 12 - 11 - 10 - 9 - 8 - 7 - 6 - 5;
• press and hold button 17;
• The program switch is moved to position 4;
• release button 17.

If the CT startup is successful, indicators 19 (OPERATION) and 20 (DOOR LOCK) on the front panel of the SM should light up, and indicator 18 (START/END) will flash.

Then perform a shortened ST in the following sequence:

1. Move the program switch to one of the positions other than 1 and 4.
2. Within 60 s, the drum begins to rotate at maximum speed (for each specific SM model, the rotation speed may be different).
3. The water inlet valves are turned on alternately in the following sequence: for 6 s through the pre-wash chamber - pause 6 s - through the softener chamber (6 s) - pause 6 s - and then through the main wash chamber to the first pressure switch level (about 8 l for SM with a laundry load capacity of 5.5 kg).
4. Within 35 s, the water heating element is turned on.
5. Within 2 minutes, the water in the tank heats up to 30°C. At the same time, the drum begins to rotate as follows (as in washing mode): 12 s clockwise - pause 3 s - 12 s counterclockwise - pause 3 s. Then the cycle repeats.
6. The valve for filling water through the softener chamber is turned on until the maximum tank level is reached. After this, the shortened ST is completed.

Note.

1. One of the disadvantages of this CT is that after its completion, water remains in the SM tank. Therefore, after starting step 6 ST, manually turn off the water, otherwise you will have to drain more than 8 liters of water (as after performing step 3).
2. The execution of ST can be interrupted at any place. To do this, you need to press and hold button 17 for 3 seconds - indicator 19 will go out and indicator 18 will light up.

Full service test

A full service test allows you to check the performance of most modes and functions of the washing machine.

To carry out the test, the washing machine must be connected to the water supply network and to the sewerage system.

The procedure for running a service test is as follows:

1. Set the program switch to position 1;
2. Press and hold button 17 (START/STOP). At the same time, switch programs as follows: 1 (initial position) - 16 - 15 - 16 - 15. The handle is held in each position for at least 1 s;
3. After this, the G1 indicator (START/END) should flash;
4. Release button 17;
5. Alternately (with a delay of 1 s) move the program switch to the following positions: 14—13—12—11—10—9—8—7—6—5—4—3—2;
6. Press and hold button 17;
7. Turn the program selection knob to position 2;
8. Release button 17.

If the service test has been started correctly, the G2 (OPERATION) and G3 (DOOR LOCK) indicators should light up on the front panel of the washing machine.

1. Then the verification operations of the service test are performed in the following sequence:
2. Move the program selection knob to one of the positions other than 1 and 11-16.
3. Press and release button 17 (START/STOP).
4. Monitor the execution of the selected service test operation (depending on the position of the program selection knob - see Table 4). During the test, indicators G2 and G3 are illuminated, but indicator 17 (START/STOP) is not.

Tips and prevention of breakdowns

• External cleaning of the machine body is carried out only with the use of a soft cloth and delicate detergents. Do not wash the machine with abrasives or solvents.
• Since failure due to contamination of the drain filter is a fairly common problem with Hansa machines, it is important to clean the filter regularly. It is recommended to do this approximately every twenty washes.
• Also periodically (once a year) clean the drain hose by removing it from the machine, having first unscrewed its back wall.
• Once a month, clean the compartment where detergents are loaded. After opening the compartment and pulling it by the handle, simultaneously press its stopper. After removing the compartment, wash it under the tap using a rag or brush, and then replace the compartment in its place.

Simple preventive measures described in the Ukrainian program “Everything Will Be Good” will allow your assistant to serve for a very long time.

The lights are on

This situation is also possible. The indicator lights up or blinks, but the machine does not start in any mode. On older models with a command device, the knob turns continuously.

Are you unplugging your washing machine?

Oh yes! No

Crash

First of all, try resetting the program. The machine may have frozen or there has been a power failure. Different brands and models have different reset mechanisms. You must read the instructions. Try unplugging for a few minutes.

On older Indesit models, to reset, do the following:

• put the switch on the point;
• launch;
• wait 3-5 seconds - the lights should blink several times;
• transfer to the washing program;
• turn it on.

Expert opinion

I work in the household appliance repair industry. Extensive experience in restoring washing machines and dishwashers.

Ask a Question

It is very difficult to reset an error in Bosch cars. Different models have their own algorithms.

Error code

On machines without a display, indicators indicate an error code that corresponds to a specific malfunction. It is deciphered using special correspondence tables. For Samsung SMA, the error values ​​can be found here.

If any difficulties arise, it is better to contact a repair specialist.

A leak

Quite often, the reason for the strange behavior of the machine is an electrical leakage to the body. First of all, it occurs on the heating element or motor, but it is necessary to check all elements of the washing machine. To do this, you need a high-quality tester with a high “resistance” limit - 40 MOhm.

Control module

Module

The lights may light or blink due to the module. If the combinations do not match your machine's fault code and there is no leak, then the control board most likely needs to be repaired or replaced.

As you can see, there are trivial reasons why the washing machine does not turn on and which you can fix yourself. But at the same time, a number of breakdowns cannot be eliminated without an experienced specialist from the service center.

Feeding key

After the power cord and FPS, the power button is checked. This key “sticks” and burns out rarely, but when operating the machine in a room with high humidity, this is possible. Especially if the Hansa model does not provide protection for the dashboard from moisture. In this case, water penetrates the case, oxidizes the contacts and disrupts the internal power supply. To check, the button must be removed:

• remove the top cover from the machine;
• Find the power button on the back of the dashboard;
• take a photograph of the location of the wires connected to the key;
• unhook the terminals from the button;
• pry up the plastic with a flat-head screwdriver and, pressing the latches, disconnect it from the body.

First, the button is called for breakdown, then the resistance on it is measured. If there is a deviation from the norm, we diagnose the breakdown and change the key. Sometimes cleaning the contacts helps restore the functionality of a part, but it’s better not to risk it and install a new one right away.

Necessary tool

Before you begin disassembling and repairing Hansa, prepare the following tools:

• screwdrivers – Phillips and flathead;
• wrenches (flat) - 19 and 8/10;
• clamp pliers;
• pliers;
• wire cutters

You will also need a special tool - a service hook.

If you need to replace bearings, stock up on a set of end tools, an extension cord for them, and a screwdriver. You will also need bearing pullers and special lubricant - a repair kit for waterproof bearings.
