An LG WM4500HBA that will not turn on has a short list of causes in LG's manual: the plug is not seated in a grounded, 3-prong, 120 V, 60 Hz outlet, the house fuse is blown or the breaker has tripped, or the washer is on a shared circuit and should be on a dedicated branch circuit. Two model-specific ones catch owners out: the control panel powers itself off after a period of inactivity, and a washer that has been below freezing will not light its display until it warms up.
Differential
Likely causes of “LG front-load or top-load washer has no power or a blank control panel”, and how to tell them apart
- 1
A plug that is not fully seated or an outlet without power
What separates it Nothing lights on the control panel and no button responds
How to confirm Push the plug firmly into a grounded 3-prong 120 V outlet and test the outlet with a lamp
- 2
A blown fuse or a tripped breaker
What separates it Other appliances on the same circuit are dead too
How to confirm Reset the circuit breaker or replace the fuse; LG says not to increase the fuse capacity
- 3
A control panel that switched off from inactivity
What separates it The panel is dark after you set a cycle and walked away
How to confirm Press the Power button; LG says the panel powers off after inactivity and that this is normal
- 4
A washer that is too cold
What separates it The display will not come on after the washer sat below freezing
How to confirm Let the washer warm up before you press Power, as LG instructs
Before you touch a setting
Record this first — changing settings destroys the evidence
- Whether any light comes on when you press Power and whether the display shows a message
- Whether other outlets on the circuit work and the breaker position
- Whether the washer has been exposed to freezing temperatures
Try in this order
0 of 5 completedCheck the plug and the outlet
ReversibleMake sure the plug is secure in a grounded 3-prong, 120 VAC, 60 Hz outlet. Test the outlet with a lamp.
Check the fuse and the breaker
ReversibleReset the circuit breaker or replace the fuse; LG says never increase the fuse capacity and that an overload must be corrected by a qualified electrician. The washer should be on a dedicated branch circuit.
Press Power again
ReversibleIf the panel timed out, press Power, choose the cycle and press Start/Pause. If Start/Pause is not pressed within a set time, which LG says varies by model from 4 to 60 minutes, the washer turns itself off.
Warm the washer if it was frozen
ReversibleIf the washer was below freezing for a long time, let it warm up before you press Power, otherwise the display will not come on.
Check the door, faucets and cycle
ReversibleClose the door with nothing caught under it, turn both faucets on fully and confirm the cycle is set, as LG's Washer will not operate list says.
