Frequently Asked Questions
•What is the resistance value I should expect across the door lock switch when the door is locked?
The resistance should be very low, close to 0 ohms, indicating a closed circuit when the door is locked.
•How do I test the communication between the MCU and the UI board?
You'll need a wiring diagram. Look for the communication wires (often labeled 'communication' or 'data'). Use a multimeter to check for voltage pulses on these wires while the washer is attempting to start. The voltage level will vary depending on the specific model, usually between 3-5V DC.
•Where is the door lock switch located on my Hotpoint washer, and how do I access it?
The door lock switch is typically located inside the washer cabinet, behind the front panel near the door. To access it, you'll need to disconnect power, remove the top panel (usually held by screws at the back), then remove the front panel (often clipped in place; use a putty knife to release the clips). Be careful not to damage the clips.
