Error code UN6 on Haier washing machine

Many Haier washing machine owners have encountered fault code UN6 or UNb. This is the same error, it may appear differently depending on the SMA model. Usually the designation is displayed during the washing or spinning stage, the machine freezes and stops working.

What kind of failure does error UN6 indicate on a Haier washing machine? How to reset the code? Will I be able to fix the problem myself, or will I have to call a technician?

Let's decipher the problem

Typically, complex repairs to the washing machine are not required in this case. Error UN6 indicates that the imbalance protection system has tripped. You should not immediately call the service center; in most cases, you can fix the problem yourself.

Drum imbalance is one of the most easily corrected SMA Hyer problems.

First of all, you need to find out why the imbalance occurred. Once you find out the reason, you can correct the situation. What should I do to reset the UN6 error?

First, open the drum door and see if the laundry is bunched up. Often small things get caught in large ones, for example, in duvet covers, so an imbalance occurs. The load goes mainly to one side of the drum, and this triggers the protective system. What to do:

• distribute the clothes evenly inside;
• start the cycle again.

Another reason for imbalance is machine overload. If too much dirty laundry has been put into the washer, you can expect the UN6 code to appear on the display. It is important to monitor the maximum permissible load weight; this indicator will differ depending on the SMA Hayer model. Take out some of the things and start the cycle again.

Often the UN6 error is displayed when, on the contrary, there are few things in the drum. For example, one T-shirt is washed. This is as harmful to the machine as overload. Therefore, it is important to observe not only the maximum, but also the minimum load weight.

Fault code UN6 may appear due to incorrect installation of the CMA. The imbalance will be constantly detected if the machine is standing on an uneven and unstable floor, for example, made of chipboard or wood. It is necessary that there is concrete or tile under the device. It is also important to straighten the position of the washing machine body to the building level - for this, the legs of the “home assistant” are twisted.

These reasons are the most common. Therefore, the first thing to check is:

• whether the laundry is bunched up;
• whether the load weight recommended by the manufacturer is observed (both maximum and minimum);
• Is the machine level and on what flooring?

If you cannot resolve the error this way, then the problem lies deeper. What else could cause an imbalance? How to repair a “home assistant”?

The problem is hiding somewhere else

Sometimes the imbalance is not a consequence of the banal “clumping” of laundry or overload. In this case, you will have to examine the washer more carefully. Let's figure out what else can provoke the UN6 error.

If your machine is new, make sure you remember to remove the shipping bolts. These clamps secure the washing machine tank in one position so that it does not dangle while the device is being transported. They are located at the rear of the tank.

It is strictly forbidden to start the washing machine with the transport screws not removed.

What consequences might there be? If you start the machine with transportation bolts inside, it may completely fail.The motor will begin to spin the drum while the container is secured with screws.

Running the washer with the transport bots not removed will void the warranty. That is, you won’t be able to count on free repairs for your automatic machine. Therefore, it is important not to forget to remove the retainers immediately after the SMA “arrives” home.

The next reason is faulty dampers. Shock absorbers dampen vibration and prevent imbalance, so if they are damaged, error is possible UN6. How to check if the struts need to be changed:

• turn off the power to the washing machine;
• remove the top housing cover;
• press firmly on the tank;
• suddenly remove your hands;
• observe the “behavior” of the tank.

Normally, the tank should immediately snap into place. If the container swings up and down for some time, it means that the dampers are not coping with their functions. The shock-absorbing elements will need to be replaced. If the reason is the weakening of the fixation of the racks, it is enough to fix the fasteners more tightly.

Another possible cause of error UN6 is damaged counterweights. Weights serve to give the machine stability. They are located in the washing machine body on the top, side and bottom - this ensures high-quality fixation of the tank on all sides.

When the counterweights become deformed, the machine begins to jump violently during the spin cycle. As a result of this, the tank-drum assembly also wobbles. The self-diagnosis system is triggered, the washing machine displays error UN6.

It is easy to check the condition of the counterweights. Remove the top cover of the washer and the back wall. If the blocks have noticeable, severe defects: cracks, chips, the weighting materials will need to be replaced.

If the damage to the blocks is minor, you can fix it yourself. For example, small cracks in counterweights can be covered with cement mortar.You can also use high-quality PVA glue to repair weights.

The next probable cause is a damaged bearing assembly. In this situation, not only the imbalance will be noticeable, but also other “symptoms”. For example, the washing machine will knock and vibrate a lot during operation, especially during the spin phase. Rusty streaks may form on the back of the tank.

To replace the bearings, you will have to almost completely disassemble the Hyer washing machine. It is necessary to pull out the tank, halve it, knock out the old rings and press in new ones. The work is quite labor-intensive, but if you follow the instructions, it can be done at home, without the help of a specialist.

Be sure to make sure that the washer is installed correctly. Stable placement of the machine will help minimize vibration and the risk of imbalance. It is best to place the SMA on a concrete or tiled floor. Experts do not recommend placing the device on linoleum, wood floors or carpet.

It is also important to align the body of the “home assistant”. You need to adjust the position of the Haier washing machine using the adjustable legs. It is also advisable to place a special anti-vibration mat under the machine. It will reduce the risk of the device sliding on the floor covering.
