⚠️ Safety Warning: Appliance repair involves electricity, gas, and moving parts. Always disconnect power before working on any appliance.
Error Code: EB4 Difficulty: Hard
Problem: Zero Watt relay alarm; low power supply voltage.
How to Fix EB4 Error (Step-by-Step)
- Unplug the washer from the power outlet and confirm the error stays cleared during a full test cycle.
- Use a multimeter to test the wall outlet to confirm it is providing the correct voltage (approximately 120V). Do not proceed if you are unsure how to do this safely.
- If the outlet is functional, remove the washer’s top panel to access the main control board.
- Visually inspect the power cord and its connection to the control board for any signs of damage, burns, or loose wires.
- If the wiring appears secure, the issue is internal to the main control board, which will require replacement.
- Disconnect all wiring from the old board and carefully transfer them to the new board.
- Reassemble the washer, plug it in, and test its functionality.
- Turn the appliance off, wait about 2 minutes, then turn it back on.
