Whirlpool washer shows error code F3 E1 on the screen when it cannot determine the water level. This signal constantly appears after the washing machine is switched on, and sometimes blocks it during operation. As a result, the unit does not start until the main failure is eliminated.
What does error F3 E1 refer to?
Error code F03 E01 is a system designation of a problem with determining the water level. The first letter with numbers shows a sensor malfunction, the second one – to a specific damage zone. In particular, problems can be associated with both the central board and other elements:
- an analog or electronic pressure switch;
- a hose;
- a pipe;
- an air trap.
What do you need to do first?
You should determine what error code F3 E1 is associated with – a failure or a breakdown. To do this, restart the appliance:
- disconnect it from the mains;
- let it stand for 15 minutes;
- connect it to power.
Then start the wash and see if error F3 E1 appears. If it disappeared, then electronic failure is the reason. If not, proceed to a thorough examination of the machine.
What elements must be checked?
First of all, pay attention to the pressure switch hose and air trap tube. They are often the source of the problem, since a dirty fluid leaves deposits on the walls, narrowing or clogging the gap. In the end, examine the control board because it also causes error code F3 E1.
Pressure switch failure
This subunit controls the volume of water in the tank, protects the heater from overheating, and gives a signal to start the drain pump. It consists of several parts, either of which is a potential “threat” to the normal operation of the relay.
At the first stage, check the water level pressure hose located between the pressure switch and the air trap. It can be twisted, pinched, bent, clogged, unsealed, wherefore error F03 E01 appears.
To eliminate the fault, you need to check whether the flexible tube is correctly placed inside the machine case, whether it has punctures and clamps. After a visual examination, disconnect it from the pressure sensor and blow it away to eliminate clogging. Make sure that foam or water did not clog it. If, after all, actions, the machine starts up normally and does not interrupt the cycle, then the problem is solved. If Whirlpool washer displays error code F3 E1 again, replace the pressure hose.
Another cause of failure is the malfunction of the pressure switch itself. It is located on the upper right side of the chassis and has a serial number of WPW10448876. You can get to it by removing the back wall and the unit cover. The relay is checked with a voltmeter set for direct current. A black probe is connected to the connector of the board PS8, pin 8 (GND), the red one is connected to PS8, pin 4. Under +5 V DC, the pressure sensor is changed. It costs $ 20 – 25.
Air trap pipe blockage
This is another thing to pay attention to since lime-fat deposits that fall from under the drain grate often settle inside the connecting tube. It can also be clogged with soap suds and leaking moisture, causing error code F03 E01.
When clogged, the nozzle captures air incorrectly, wherefore it presses on the pressure switch. As a result, it determines the wrong amount of water in the tank, which sends a signal to the main control board. The solution is to clean the tube with the thorough removal of blockages.
It is a frequent reason for error F3 E1. In this case, the signal appears periodically, disappearing for an indefinite time. This is due to the wearing out of the harness in the segment between the pressure switch and the control module. Such a defect is possible due to the vibration of the washing machine during operation.
Check wiring with a multimeter. If there is no continuity, strip, twist, and insulate the broken ends. Also, make sure that the PS8 connector is fully inserted into the central module and that the pressure sensor harness is securely connected.
Control module failure
The mainboard is checked last when no other action has helped. At the same time, Whirlpool washer displays error code F3 E1 either immediately after switching on the device or while fulfilling the program.
The electronic board W11201274 monitors all the functions of the machine, including tank filling. Therefore, if the elements that are responsible for the water level switch are damaged in it, they should be re-soldered. An unrepairable module is replaced entirely. Its cost is $ 271.
