Error F02 in Whirlpool washing machine

The longer we use the washing machine, the higher the risk of various problems. Error F02 in a Whirlpool washing machine is considered one of the most common. It signals that the system has detected a leak or blockage in the intake valve. In such a situation, the aqua-stop will work, and household appliances will block the current operating cycle. We list the main causes of this problem, as well as what can be done about it at home.

Why did Aquastop work?

Fault code F02 informs the user that his downstairs neighbors' floors and ceilings have just been protected from flooding using the AquaStop system. This smart system works on both sides of the washing machine at once: an electromagnetic valve is installed in the filler sleeve, and a sensor with a float is located below in the tray. If the “home assistant” detects a leak, the following will happen in the system:

• the liquid will flow down the body and tank directly into the pan;
• when the water level is exceeded, the float will rise up;
• when the float moves to a vertical position, the sensor will operate;
• the valve mechanism will receive a signal about a leak in the system, as well as an order to stop fluid intake;
• the valve will stop the water;
• the CM control module will stop working;
• The machine will switch off immediately.

Thus, the AquaStop system is activated in a situation where an excessive amount of liquid accumulates in the tray of a Whirlpool washing machine. Aquastop almost never works for no apparent reason, so it is usually activated during leaks. Why could water collect in the pan?

• The tightness of the drain or fill hose is broken - they could tear or fall off the tee.
• The clamps on the pipes are loose.
• The washing machine tank is damaged.
• The powder receptacle is clogged because the pipe in the hopper is clogged, or a foreign object is stuck in it.
• The seal has moved.
• The tympanic cuff is deformed.

If the aqua-stop is triggered, the operation of the machine will be stopped, and fault code F02 will appear on the display. When the equipment does not have a display, the machine will inform the user about the problem with a bright indication. All possible causes are listed, let's move on to diagnostics and repair.

We eliminate the breakdown of Aquastop

Immediately after the aquastop is activated, the “home assistant” must be carefully checked. To do this, you first need to turn off the control system, get rid of the waste fluid and find out what exactly is leaking in the CM housing. The easiest way is to call a service center specialist, but you can deal with this simple problem yourself. What to do to fix the problem at home?

• Interrupt the activated work cycle, which can be done by turning the program selector knob to the “Off” position.
• Activate drain mode.

If the instrument panel does not respond to user commands, drain all waste fluid using a waste filter.

• Unplug the washing machine.
• Tilt the body of the device until all the liquid has poured out of the pan.

Only after all the manipulations have been done can you begin to diagnose the “home assistant”. The aquastop system turns off automatically immediately after the water is removed from the pan and the float returns to its original position.However, the same problem will return in the next work cycle if the situation is not corrected. Therefore, you need to carefully check all possible causes of the problem.

You should start with the inlet hose, because sometimes it can fall off the clamps or even crack, which is why leakage occurs. If everything is in order with the filling hose, then it is necessary to check the condition of all other pipes going to the tank, pump and powder receiver, as well as the tightness of the main drain hose.

Then you need to study the pump and volute, because if these parts of the drainage system are faulty, then the outflow of water will be stopped, the washing machine will begin to overflow, and a leak will form. Then you should evaluate the cuff and dispenser for cracks. If after this the cause of the malfunction is not identified, you will have to partially disassemble the unit to check the oil seal and tank. Turning on the aquastop with a dry sump indicates that the sensor itself is damaged, so you need to test it using a regular multimeter. If it turns out that the aquastop itself is to blame, then repairs in this case are not needed - you just need to replace the element.

Inlet valve clogged

What to do if all the elements are working properly, including the aquastop system? In this situation, it is necessary to additionally inspect the filter mesh installed in the inlet valve. If the filter element is clogged, this can also cause fault code F02. Follow the instructions to check the filter.

• Disconnect the “home assistant” from all communications.
• Provide free access to the rear wall of the CM.
• Remove the inlet hose.
• Find the filter element at the location where the filling hose is installed and remove it, first securing it with pliers.
• Rinse the mesh under a powerful stream of hot tap water or soak it in a citric acid solution for several hours.
• Reinstall all parts.

After these manipulations, the collection of water should become much faster, as you can see during the idle cycle. If error F02 disappears after this, then the repair was successful.
