LOCF error code on a Haier washing machine

What does the LOCF error on a Haier washing machine mean? This is a standard system notification reminding you to enable the "Child Lock" feature. It's not considered a fault code, but rather a simple informational message.

To clear the message, you need to turn off Child Mode. We'll explain how to get rid of the LOCF code. We'll also discuss what to do if the message won't clear from your washing machine's display.

Turn off the protective function

The LOCF notification is not considered an error. The information message does not indicate a breakdown, but rather the launch of child mode. The washing machine panel is locked, which prevents accidental button pressing.

To remove the LOCF message, you must deactivate the Child Protection option.

How do you disable the baby mode on Haier washing machines? To deactivate this option, simultaneously press and hold the "Delayed Start" and "i-Time" buttons on the control panel. This combination is common on most Haier models.

It's best to check the instructions for your washing machine. They'll tell you which buttons to press to exit child mode. The button combination may vary on other models. On some automatic machines, the feature is activated by pressing "Child Lock" once, and deactivated in the same way.

If you don't have instructions, carefully examine the Haier washing machine's control panel. Users typically intuitively understand which keys are used to lock the washing machine. The required buttons are marked with a corresponding image or text.

Problems with the control board

Although rare, there are cases where you can't clear the LOCF message. Neither pressing the appropriate buttons nor restarting the Haier washing machine helps. In this situation, repairs may be required, so you'll need to run a microcontroller diagnostic.

Repairing the electronic unit will cost a pretty penny. A technician will charge $10-$20 for an inspection, and another $50 for troubleshooting. A complete control module replacement will cost around $100. So, if your washing machine is no longer under warranty, you might want to try fixing it yourself first. Here are detailed instructions.

The control electronic module of the Haier washing machine is located in the front part of the body, behind the control panel.

To access the electronic module of a Haier washing machine, you need to:

• de-energize the washing machine by pulling the power cord out of the socket;
• turn off the water supply to the appliance by turning the tap on the pipe;
• disconnect the inlet hose from the washing machine;
• remove the detergent drawer from the machine;
• remove the two screws securing the top panel of the washing machine housing;
• remove the "top";
• unscrew the bolts around the perimeter of the washing machine dashboard;
• remove the control panel by releasing the latches;
• take a photo of the wiring diagram connecting the instrument panel to the electronic module;
• disconnect wires and connectors;
• remove the dashboard and put it aside;
• unscrew the screws holding the control module;
• remove the electronic board from the washing machine housing.

The next step is to inspect the control module. Often, defects on the board are immediately noticeable. The unit may have bulges, dark spots, burnt areas, or traces of corrosion.

If the control module appears intact, a thorough inspection of the board is required. A multimeter is used to test all semiconductors on the unit. If you have no experience working with electronics, it is better to call a qualified technician for diagnostics.

Replacing a burned-out semiconductor on the board, re-soldering the track, or cleaning the contacts often helps fix the problem. Sometimes, replacing the entire electronic module is the only solution.

A new control unit is purchased for a specific Haier washing machine, based on the model name and serial number. The module is installed in its original location, secured with screws, and wires are connected. Afterward, you can begin reassembling the washing machine housing.

After repairing or replacing the electronic module, you should test your Haier washing machine. Start the machine. Next, press the buttons on the dashboard one by one, and rotate the programmer. If the washing machine is operating correctly and the "brain" responds to your commands, then everything went well. Activate the idle cycle and watch the machine complete the program.

Don't disassemble the machine yourself or attempt to repair it if it's still under warranty. In this case, call the service center immediately. Specialists will diagnose and repair the washing machine free of charge if the problem is not the user's fault.
