The four digit code on the display of your Whirlpool appliance is pretty easy to decipher. The first two signs stand for the sensor failure, while the second half of the code specifies the area where it is located. In case with F3 E1 Error code your machine I pointing your attention to the pressostat, which is responsible for the control of the water level.
What can cause the F3 E1 Error?
In simple words, the F3 E1 code indicates you machine has problems with determination of the water level. In most cases, it can be caused by the issues with the water-level sensor, such as damage to the detector or problems with the wire connections.
The same error can be caused by the damaged or clogged hosepipe and air trap, or by a breakage of the control unit (whether a one-time or a more serious).
How to fix the F3 E1 Error?
First of all, you have to eliminate the one-time control panel malfunction from the list of possible reasons. Switch off the device and unplug it from the socket for a few minutes. Restart it and see whether the error code is still indicated on the display. If no — lucky you, it was just a system glitch and now you can start your washing process.
If this rebooting the appliance didn’t help, start an examination of the pressure switch and other elements — air trap and the pressure pipe. They might have been clogged at damaged, so check them thoroughly and clean if necessary or replace the damaged components. The pipe of the pressostat can be displaced, so fix it, connect it properly and tightly.
If all the above checks didn’t help you in resetting the error, then it’s either the control unit or the water level pressure switch causing the error. To begin with, inspect the wiring connection of the pressure switch. Some contacts can be loosened or burned, so they have to be fixed or replaced.
The multimeter will be very useful in checking the wires, along with the pressure switch itself.
If you made sure the error is caused not by pressostat and the connected components, then its most likely the failure of the main control module, which is the most important element of your device and has to be diagnosed properly and repaired or replaced by a professional. Sometimes the issues can be solved quickly, just by fixing one or two contacts, but in the worst cases, the whole unit has to be replaced.
