Dead after power outage

Hello. I need the make/model number to help you most accurately. From the symptom you describe, there might be a main fuse located on or near the main control board which has opened, killing power to the unit. Clues: totally dead--no lights--an open door will not affect indicator lights, the unit won't do anything though--safety(nothing will happen until the door is closed) Have you had a power outage recently? Usually 3-4 weeks after an outage, the damaged chips on the boards start to fail. This can be evidenced by blown control panels, blown main boards, etc. Make sure 120 volts *is* getting to the dishwasher--check the power connections below(be careful). If the breaker has tripped, reset it and see if the unit runs. Troubleshooting starts from the outside and proceeds inward, eliminating the obvious and moving to ever more complex problems until the culprit is found. Definitely supply me with that model number so I can see what I'm dealing with and guide you correctly. Thanks!

If the unit is totally dead, the main board most likely is blown. You say you checked the "fuse"--is there a fuse on the dishwasher or are you referring to the electrical panel fuse box in your house? Did you recently have a power outage? Usually, within 3-4 weeks after having one, appliances will start failing due to damaged chips on the main control boards. The problem could also be a damaged user interface board. If 120volts is getting to the main board but the unit is dead, I'd highly suspect the board is bad. I've also seen lots of bug infestation damage to boards--classic signs are roach tracks in and around the boards--they're attracted to the warmth and will walk across the live boards, shorting them out.

Make sure your circuit breaker in the main breaker box has not tripped, or "poped". It will be one a little out of place and a bit loose if it has tripped. Turn it off and back on to reset. If it tripps immediately, you have a short somewhere, possibly in the dishwasher, so you will need an electrician and or Appliance tec. to find and fix.

Has the circuit breaker / fuse in the meter box tripped or blown as well? If the machine tripped or blew a fuse, it is common for the heater element to be the cause or you have a water leak internally and its shorted something.

please follow this steps and fix it. God bless you

1. No power to the dishwasher
Make sure there's power getting to the dishwasher. Check for a tripped circuit breaker or a blown fuse. Check the wall socket for power. Sometimes the power cord disconnects at the dishwasher (inside the junction box, behind the bottom kick panel), if this is the case, the wiring must be repaired or replaced.

2. Door switch
Replace if defective.

3. Timer or Control Electronic
Replace if defective (note: uncommon problem).

4. Selector switch
Replace if defective (note: uncommon problem).

Appears to be a short in tank circuit probably cause by a water leak in tank. These usually wear a rusty hole in the tank inside the cover and are not seen unless the thermostat covers are taken off. I would remove them and do a visual thoroughly. Anytime a fuse blows or a breaker trips is always a dead short unless you have a bad breaker. I would check those as well for vibrating, chattering noises, and/or smoking. If any of this persist, replace breaker. A melted heat element could trip them, but not usually for it leaves an open circuit instead of a shorted one.

Most Whirlpool manufactured dishwashers have a thermal fuse, located inside the operator console. When tripped, the dishwasher will not run. A power outage can cause the thermal fuse to trip. It cannot be reset and has to be replaced, if bad. Please post back with your COMPLETE MODEL NUMBER (located around the door opening) so I can determine the configuration of your dishwasher and explain how to access any potential fuses. -->

from online Microwave Repair Manual: Totally dead oven (no lights, no clock, no display, no fan, no heat...)First, check power to the outlet using a lamp or radio you know works. The fuse or circuit breaker at your service panel may have blown/tripped due to an overload or fault in the microwave oven or some other appliance. You may just have too many appliances plugged into this circuit - microwave ovens are high current appliances and should be on a dedicated circuit if possible. If you attempt to run a heating appliance like a toaster or fryer at the same time, you *will* blow the fuse or trip the circuit breaker. A refrigerator should never be plugged into the same circuit for this reason as well - you really don't want it to be without power because of your popcorn!

If you find the fuse blown or circuit breaker tripped, unplug everything from the circuit to which the microwave is connected (keep in mind that other outlets may be fed from the same circuit). Replace the fuse or reset the circuit breaker. If the same thing happens again, you have a problem with the outlet or other wiring on the same branch circuit. If plugging in the microwave causes the fuse to blow or circuit breaker to trip immediately, there is a short circuit in the power cord or elsewhere.

The microwave oven may be powered from a GFCI outlet or downstream of one and the GFCI may have tripped. (Removing a broken oven lamp has been known to happen.) The GFCI outlet may not be in an obvious location but first check the countertop outlets. The tripped GFCI could be in the garage or almost anywhere else! Pushing the RESET button may be all that's needed.

Next, try to set the clock. With some ovens the screen will be totally blank following a power outage - there may be nothing wrong with it. Furthermore, some ovens will not allow you perform any cooking related actions until the clock is set to a valid time.

Assuming these are not your problems, a fuse has probably blown although a dead controller is a possibility.

While you can do some repairs on your microwave, what you don't know can kill you... even on an unplugged microwave, so make sure you understand the dangers and how to reduce them before you try anything inside a microwave. If you want to do more yourself, go to the link at the top of this post.

Do the following:

1. Check the power from the wall outlet or the branch circuit itself.
2. Check for a blown fuse or a tripped circuit breaker.
3. Check the wiring connections of the dishwasher from the house wiring.
   
4. Check the door switch. Remove the control panel cover or the interior liner of the door whenever it is applicable. Replace if defective.
5. Check the timer or selector switch. replace if defective.

If the circuit breaker was tripped, more likely the fuse inside the TV power supply might also be blown. If that is the case there might be a short circuit in the power supply components, more likely on a diode or transistor/mosfet.

Good Luck.
