 INTRODUCTION

This manual is designed to guide in the diagnostic process and, if applicable,

repair of recent models of WHIRLPOOL washing machines with electronic board.

It is necessary to have knowledge of electricity and mechanics to be able to face the process.
repair of these equipment. The personnel performing the repairs must possess
basic knowledge such as the use of a multimeter, measuring voltage, resistance,
continuity, etc.

The delivery and design of this course responds to needs and concerns from
of the personnel dedicated to repair due to the lack of educational material and information
technique.

We will address topics such as equipment reset, service mode, and interpretation of
error codes through the control panel, testing some components,
essential for a correct diagnosis.

The control card will not be the subject of our study on this occasion, we will focus on
in detecting the problem, if it is identified that the issue is the card, it will be
to channel the repair.

This course does not aim to repair all the faults of these devices, the main objective
is to guide the technician in the repair, providing the theoretical foundations for this. However,
will have the necessary skills to undertake an appropriate diagnostic process.

The preparation of this manual is based on the technical information that appears in each
washing machine, however, experience in servicing these machines is essential, for
elaborate it.

In this first installment, we will only address the programming part, in a next one.
we will fully engage in the measurement of components and their repair.

 DIAGNOSTIC GUIDE

This part of the manual describes the procedure to be followed to address the equipment review.
washing. It is important to note the considerations that must be taken into account to carry out a
appropriate check of the unit.

Before carrying out maintenance or repair work, please check the following:

Make sure there is no current in the wall outlet.

The hot and cold water supply valve and hoses are open, without
obstructions and with good pressure?

All tests must be carried out with a multimeter (voltmeter, milliammeter) or

DIGITAL VOLTMETER (digital-voltmeter) with a sensitivity of 20,000 Ω per DC volt or
more.

The resistance tests must be performed with the washing machine disconnected.

Check all wiring harnesses and connections before replacing components.

Ensure that the connectors are properly inserted, check for loose or broken cables, and
check that the wires are securely attached at the terminals.

One of the possible causes that can cause a device to not function is corrosion or
humidity in the joints. Use an ohmmeter to check the continuity through
suspicious connections.

DIAGNOSTIC LED - MAIN CONTROL

This team has been provided with a tool for problem solving. This
the tool is located at the back of the main card and consists of a Led of
green color, this LED lit will indicate if the internal power supply of the
the card is working, if the LED does not turn on it is indicative of a fault
operation, what should be done in this case is to remove all the connectors from the

It is the main card.

 TEST METHOD FOR DIAGNOSIS

These tests allow service personnel to test and verify all inputs to the
main control card. You may want to do a quick overall check of the
washer in test mode before making any changes or measurements of any kind
specific piece.

METHOD OF INTERPRETING FAULT CODES

This sub-menu is very important as it allows you to make a

assessment of the probable components that may be damaged or
causing the failure, it is recommended that before starting to
disassemble the equipment a scan is performed through this
method, it is fast and will save a lot of time in the process of
diagnosis.

The menu of Fault and Error codes is displayed on the LED panel, alternating in
intervals of 1 second, between the Fault and Error.

All Faults and Errors have an assigned number depending on the code.

what the suspicious component indicates.

If the Sensing or Filling LED is on, then the displayed code will be the number of

 AUTOMATIC TEST MODE

It is advisable to perform the automatic test mode to ensure that the washing machine
is carrying out all functions, that is, that all components that
they intervene in the different washing cycles, performing their function in the time that it needs
it corresponds. It is also recommended for a quick test of a washing cycle, once
the repair has been carried out as a check of the equipment.

To access the automatic test mode, it is necessary to enter service mode.

First, once in service mode, turn the selector knob until it lights up.

Press the START button to begin the automatic test.

Once in Automatic mode, the washing machine will carry out a wash cycle to verify
all functions.

By pressing the START button, you will advance to the next step in the cycle.

You can exit this Automatic test mode at any time by pressing and without

 MANUAL TESTING METHOD

To enter Manual test mode, you must first access service mode.
First, once in this, the selector knob should be turned until the LEDs turn on.
Express and Ready, just as shown in the figure below.

TO FILL TO WASH RINSE SQUEEZE READY

Once these LEDs are turned on, press START to enter Manual mode.

Once in Manual mode, the washing machine will have all outputs turned off.

To select the output that will be tested, the selector knob will be used.

The START button will activate or deactivate the previously selected output.

When you select an output, its corresponding LED will flash.

At any time you can exit this trial mode simply by pressing and holding the
START button, for 3 seconds.

IMPORTANT; AS A SECURITY MEASURE, THE LID SWITCH MUST BE

CLOSED WITH THE INSURANCE ACTIVATED.

NOTE; THIS PROCESS SHOULD NOT LAST MORE THAN 5 MINUTES.

13
 CALIBRATION MODE

It is important to access this menu whenever any of the

following components: control card, tub, motor, actuator, suspension or capacitor.
If the washing machine is not calibrated, the washing cycle will be poor or insufficient.

To access Calibration mode, you must first enter the main service mode,
Once installed there, turn the selector knob until the RINSE LED lights up.

FILL WASH RINSE SQUEEZE READY

NOTE; THE NAMES OF THE LEDS MAY VARY DEPENDING ON THE MODEL.

Press START to enter Calibration mode, the Washing Machine will begin calibration.
All the LEDs will light up.

Once calibration begins, it should not be interrupted, nor should it be moved.

do not disconnect the washing machine from the power source; if something like this happens, the process is repeated

The lid switch must be in place.

The tub must be empty without clothes or water.

The Calibration cycle lasts approximately 2-4 minutes. When the lid lock is deactivated and
the washing machine enters standby, the calibration is complete.

 METHOD OF CHECKING THE TACHOMETER

To access the tachometer verification mode, you must first enter the mode of
main service, once inside turn the selector knob until the LEDs light up
WASH AND DONE, as shown in the figure:

FILL WASH RINSE SQUEEZE READY

NOTE: THE NAMES OF THE LEDS MAY VARY DEPENDING ON THE MODEL.

Press the HOME key to start the tachometer check.

To verify the tachometer, the front panel LEDs are used to indicate its frequency.
(The RPM of the tub).

For example, if you slowly rotate the tub with your hand, as the tub turns, the LEDs
READY, SQUEEZE, RINSE, AND WASH light up one at a time, repeating the cycle.
The ignition time is generated by the tachometer itself.
