Machine wasn't starting program so I turned it off and now it won't turn on again - display is completely dead. The power socket is fine I tested other appliances.

turn the deck pto off and try again

I have a LG wt5001cw top loader washer and after it completed its cycle it shut off and will not turn back on. How do I fix it?

do the following steps: God bless you
To start test program, press and hold both POWER SCRUB PLUS and RINSE & HOLD program buttons, then turn unit on by pressing ON/OFF button. When program buttons are released, lights above them will flash. To end test program, press ON/OFF button.To check program indicator lights (POWER SCRUB PLUS, REGULAR WASH and RINSE & HOLD), press and hold each program button. When REGULAR WASH program button is pressed, CLEAN light also comes on.
To start testing, press both POWER SCRUB PLUS and RINSE & HOLD buttons a second time. When testing has ended and a fault was detected, the following indicator lights will be lit:
POWER SCRUB PLUS = Heater fault
REGULAR WASH = Water filling fault (over or under filling)
RINSE & HOLD = NTC (temperature sensor) fault ? note circulation motor stops shortly after it started during an NTC fault
To check for heater, high limit or flow switch problems, start testing until heating starts. Using a meter with a current coil, measure current going into dishwasher. If current is ~ 11 A, then heater, high limit and flow switch are OK. If current stays at ~ 1.5-2 A, then heater, high limit or flow switch are faulty.
If water level switch (f1) has failed (opened), REGULAR WASH light will come on and unit will continually fill and drain where testing won't be completed. If flow switch (e5) has failed (opened), water won't heat (to 150?F) and water won?t stop circulating. If NTC probe (f2/f4) has failed (opened), RINSE & HOLD light will come on immediately and testing will end shortly after water has started circulating.
If more than one fault occurs, more than one light will be lit.

Most times unplugging a washer for 5 min or so will reset to factory. Some units just a quick unplug works too. But I'm not totally familiar with yours.
If it's going to be hard to unplug just turn off the breaker to it.
Hope this helps

Sounds like you have a toasted battery or alternator. Have you performed a load test on the battery? Have you tried to charge the battery? First remove the battery and charge it externally from the vehicle. If the battery won't hold a charge, or won't hold a charge of 12 volts, replace it. Once you have the vehicle started, test the operation of the alternator. It should be putting out at least 13 volts back to the battery to keep it charged - if it is putting less than 13 volts or more than 16 volts, replace the alternator.

Lets start at square-one. Have you checked the plug fuse ? Have you checked that the 2-pin mains plug is firmly inserted into the socket on the back of the machine ?
If yes to the above ... are there any lights on at all ... sewing light, display backlight ?
If it's completely dead, it's most likely the power supply 'L'-print which is a separate module screwed into the back of the machine below the spool holders. Your best bet is to get the machine checked-out by a Bernina service agent.

if you mean it won`t start when you say won`t turn over then its probably the fuel pump has quit working and needs replacing.

How long did you let it charge, when the device is completely drained of power it may not turn on at first when you connect it. Let it charge for a little while and come back to see if it fixes it. Failing that, your probably going to have to contact apple for warranty help.

Hi.

Sounds more like a power supply problem. First test the on/off switch by tracing the wires to where it connects to the mother board. The plug is usually marked "pwr sw" . Unplug the wire from the board & short out the 2 pins where the switch was plugged in using a small screw driver or any other conductive material. If the pc still fails to turn on, try replacing the power supply.
Best wishes,

Diagnostic Test:
The diagnostic test is performed by using the Program Knob. To START THE TEST:
• On non-digital display models, turn the Program Knob to start position, Drain/Spin.
• On digital display models, turn the Program Knob to start position, Touch Up. (NOTE: If the model has a timer dial that
can be rotated 360°, turn the Program Knob to start position, Drain/Spin.
• Press Pause Cancel to turn off LEDs.
• Within 5 seconds, press and hold the Option and Pause Cancel buttons until LEDs start sequentially chasing, then
release buttons.
