    Thanks CHRF...If I get another coffee maker, how do I prevent this happening again? It is just as I had thought. The coffe maker is fried, it now sits on my counter, a new and shiny not usable coffee maker, mocking me!!

More than likely, either the coffee maker has a fuse inside of it, or the inverters lack of a perfect sine wave a/c fried it.

    maybe you can find a coffee maker that runs on dc power, or buy more expensive inverters that have closer to a perfect sine wave a/c power. the way i understand it, most inverters sine wave is actually square wave. so alot of appliances will work fine, though some will not. usually has to do with how much electronics the appliance itself has in it to clean up the incoming power. i bet there are some web sights that can teach you more. good luck, and happy sunning. chris frost.

My LG front load washing machine, model WM3001HWA, has no power. What can I do?


Hello Kyle;

My name is Peter. I am a retired field service appliance technician.

You have 3 sensors in your unit, a thermal sensor, a position sensor and a door lock switch. These components will prevent you from running but, would not affect your power.

I assume you checked your circuit breaker to make sure you have power to your washing machine.

The slightest change in power supply, electrical power surge or power outage will knock out your boards. Magnetic fields and static electricity will knock out your boards. Are your appliances near a main power supply line in your home?

All appliance manufacturers recommend surge protectors if you have control boards in your appliance. Individual wall socket surge protectors cost about $20.00 at your local Home Depot or where ever. This is a good investment.

Ok, your have 3 control boards in your unit. One is the digital display board which has nothing to due with power supply.

The others are your main control board and your control panel board. Each of which can turn off power. The highest probability is the main control board. The part number for this board is EBR 44289820. The part cost $225.00 locally. You can probably get it for $180.00 if you search the internet. This is item A450 on the following link.

Remember static electricity can not out a board. Ground yourself by rubbing your hands over something that is steel. Either unplug your unit or turn the power off at your household fuse box. There are several clips holding the board in the casing. you must push outward to remove the board. Inspect the circuit back side for burn marks. If there are no burn marks you can still have a board component failure. DO NOT DISCONNECT ANY CONNECTOR PLUG IN. When you replace the board, you will replace one at a time.

I have a Whirlpool top loading washer. The motor does not come on on any of the wash cycles but it does come on during the rinse cycles. Does this sound like a timer problem? Could this have been caused...


sounds like it could be a fault caused by a power surge, it may be worth checking the carbon brushes in the motor if they are worn down the wont supply power to the armature especially under a heavey load such as washing or a fast spin a tell tale sign is clothes seem to be still really wet after a spin

It is showing 12 minutes but will not allow me to cancel, start, or do anything. We had a power surge and wonder if that has something to do with it.


That is quite possible..... I would unplug the power cord from the Outlet. Wait about 5 minutes and replug the washer and restart push cancel and then restart your wash. Good Luck hopefully the power surge didn't cause any permanent damage to the control board.......

The washer is only 1.5 years old and has been working fine until a recent power outage. After the poer was restored, the spin cycle quit working. Any suggestions?


Reset the motor is what you must do.

To Reset the Inverter Board: Push the timer knob in so the washer is idle. Unplug the machine for one minute. Plug back in and raise and lower the lid six times within 12 seconds.

After resetting the inverter board, put the machine in a spin cycle and see if it runs. If not, check for a green blinking light on the inverter board. It will flash failure codes according to the picture above. If no light you probably have a blown fuse built into the neutral side of the harness on the white/red wire.

Model ATF6000751. Replaced speed control board a month ago when final spin failed. Worked fine until yesterday. Could something else be causing the board to go bad?


Power Surges. In my area we suspect that 70 to 80% of the repairs here are caused by power surges. They happen all the time, andyou do not have to lose power to have one. They can happen when you have lightning, windstorms or beutiful sunny days. You have to have a 2000 joule surge protector or higher on your washer, refer, microwave oven, and gas stove or dryer if you have them. For your washer , gas dryer, and refer you have to have a rectangular box wall mount surge protector. You cannot have a power strip surge protector on a cord as moisture can get into it and cause electrical fires. I have seen three major fires caused by power strips behind washers. Lowes and Best Buy sell wall mounted box surge protectors with a 2150 joule rating that have 3 plugs on each side that rotate from front to the side so that you can plug your refrigerator into the side and not have the refer sit out from the wall any more. Good Luck, Appliance Specialists.

Been setting in storage a year when all hooked up it starts up just fine then quits and sets there with the timer running but wont wash or spin or nothing wont fill with water


When you mention that it starts up fine. Do you mean that the machine initially takes in water, but then nothing after that. Or does it simply power on, but no water comes into the machine.

If no water comes in initially, then it is most likely your inlet valve.

If water comes in but no motor action, then it could be a raft of things. Disconnect the power source. Open the top hatch and the back panel. Make sure the drive belt has not come off during transport. Also check to see if no wiring connection has come loose. NOTE: Make sure the machine is off and disconnected from the power plug.

If you can't spot anything loose then it is best to get a service technician to diagnose the problem.

Initial Power surge


look on the back of the unit, for the average numbers for volts/amps..multiply that by 1.66(for peak power) and add a factor of 25% for power factor correction from your inverter. You may want to place a resistor/diode array in line with that, so that any reverse surge from the power cycling of the washer, won't back up your inverter feed.
