EUAR error in Haier washing machine

EUAR error in Haier washing machine Most washing machine errors are displayed as a letter and a number, but there are unique cases. One such example is the EUAR error in a Haier washing machine, which alerts the user to critical issues with the washing machine's control module. This error is considered one of the most frustrating, as when it occurs, the washing machine stops working, makes no sounds, and doesn't respond to commands. Let's explore whether there's anything you can do yourself in this specific situation.

Repair or replace the module?

Perhaps the most serious problem that can occur with a washing machine is a malfunction of the control module, the "brain" of the entire appliance. There are only two options if your appliance displays the EUAR error code, and both are extremely costly.

Repairing the control module at a service center. In Haier appliances, the module isn't so complex that it's impossible to repair, but it will cost around $50, if not more. Besides the cost, another drawback is the short lifespan, as even repair technicians only offer a 4-8 month warranty. So, if the part fails again within a year, you'll have to pay for repeat work.

You shouldn't try to repair the board yourself, because without the proper experience and knowledge, you can accidentally damage the component so badly that you'll have to throw it away.

Buying a control module and replacing it yourself is a more reliable, but not cheaper, option, as a new component can cost between $50 and $100, depending on the Haier washing machine model. The advantage is that you can replace the component yourself at home, and it's relatively quick. Hiring a professional will cost an additional $20–$30.

Both options have their pros and cons, so everyone must decide for themselves what's most important. In the next section, we'll detail the replacement process for those who prioritize long-lasting repairs.

We are rearranging the control boards

All Haier home assistants have a control module located behind the front panel of the case. The exact location of the board depends on whether the machine has a top-loading or front-loading system. This element is large, so it's fairly easy to locate inside the case. What should I do to remove it?

Disconnect the automatic washing machine from all communications.
Remove the bolts holding the top panel of the washing machine, slide it back and pull it up.
Remove the powder receptacle so that it does not interfere with the dismantling process.
Remove the screws located near the powder receptacle opening.
Remove the bolts securing the CM control panel.
Remove the panel itself, having first disconnected the latches and wires.

Be sure to take a couple of photos of the wiring so that you can refer to the example of how to properly connect the element during reassembly.

Remove the screws that secure the control module.
Remove the unit from its seat.

Carefully inspect the board for damage. This could include traces of carbon, rust, scorched elements, or mechanical damage. In rare cases, a simple soldering of traces or replacement of a capacitor can restore the module's functionality, but more often than not, a much more complex repair is required, beyond the capabilities of the average user. If the warranty card for the washing machine If Haier is no longer in service, you can try to fix the module yourself; otherwise, it's best to call a service center specialist.

Installing the new module is hassle-free, as we follow our instructions in reverse order. Secure the circuit board to the housing, connect the wiring, reinstall all other components, connect the appliance to the power supply and water supply, and then immediately run a test cycle. If the machine responds to user input and operates properly, the repair has been successful.
