Using this Westinghouse main control PCB module is straightforward. First, make sure your washer/dryer is turned off and unplugged from the power source. Then, carefully remove the old control module and replace it with this new one. Connect all the wires properly according to the original setup. When the module is in place, plug the appliance back in and turn it on to check if it's working. Here are some important notes. Always double - check for other possible faults in the machine before installing this module. Water leaks, problems with the main motor, or other components connected to the module could have caused the previous failure. If there's damage due to external causes, the warranty won't apply. For maintenance, keep the module clean and dry. Avoid exposing it to excessive moisture or dust. If you notice any strange noises or malfunctions after installation, turn off the machine immediately and contact a professional for help.
