Re: wiring a new dishwasher

No but aluminum wiring is dangering by itself when it heats it expands when it cools it contracts and loosens its own connections not a great in my opinion but wont hurt the dish washer

I have a shu43 bosch dishwasher and the whole machine is dead. No power. The circuit breaker is good but I would have to pull the dishwaher out to check the outlet. Is there an internal fuse?

There is no internal fuse (at least I've not seen or replaced any) on Bosch dishwashers. The most typical problems for Bosch are: 1) one of the power cord connections to the internal wiring is corroded and doesn't make a contact; or 2) the power button has failed.

The number one is so far the most common problem. To check: Turn off the power to the dishwasher by any means necessary. Remove the kick panel on the bottom. There should be a small metal box with power cord and 2 or 3 wires coming into it. Remove screw(s) holding the cover on that box. There should be 2 or 3 wires connected to the power cord wires by wire nuts. Any burnt insulation or wire nut will be the problem area. Cut burnt wires, remove 1/2" of insulation and clean of both connecting wires to bare copper. If you have an electrical contact grease - apply to copper. Install new wire nut.

Good luck,

My Kenmore dishwasher keeps blowing a fuse. Four within a year. Why?

Marginal wiring to to the outlet for the load the washer places on it. When that occurs, more current is required to keep motor running at speed which in turn blows the fuse.

If machine is on an extension cord by necessity, use a 12 gauge wire, most are 14 guage and sometimes 16. I

If you are plugged into an outlet, shut off power and check to see if the wires were stabbed into the back of the outlet. This entails removing the cover, and removing the outlet. If the iwres are not under the screws on the side, it is a "stab-in" installation which is common. If a newer house this is most probable. Replace outlet and put the house wiring under the screws- do not use the "stab in" method of connection. Form a loop with about 5/8 inch of bare copper, white goes to the silvery side and the black goes to the brassy side. Make sure the loop is "clockwise" under the screw head so it is a secure connection. That may be enough to rememdy it.

Should it blow again, check to see if there are other outlets in that branch, if so replace easch outlet placing the wiring under the screw heads.

Doing this will reduce the voltage drops in that branch, and also reduce the possibility of a fire as well. You will likely see some scorching on the wires or old receptacles.

The new outlets are cheap enough in price that you should just replace them not reuse them. If you wanted to go to better quality receptacles you can do that too.

IF you have aluminum wiring, in my honest opinion- go get some copper for that run and pull new, or do surface mount wiring if pulling the run is not an option. Getting it inspected is also a really good idea. Especially if you never did any work like that before.

Don't understand the incomprehensible door and general installation instructions for the aqua star. Just uses pictures, anywhere available that uses WORDS?

  • 1 what you'll need
    Electric drill and hole cutting bit
    Adjustable wrench
    Teflon pipe tape
    Drain pipe for dishwasher
    Dishwasher connection kit - available at your home store (should contain water supply line for dishwasher as well as necessary connectors and compression couplers).
    New dishwasher

  • 2Determine that you have access to the hot water supply line, the drainpipe and an electrical connection under the sink. Installing the dishwasher will require extending the hot water supply line to the dishwasher, connecting the dishwasher drain to the drainpipe under the sink, and plugging the dishwasher in. If your home was not plumbed in anticipation of a dishwasher, you will need to change some fittings under the sink to make these connections possible. (See below)
  • 3Read the instruction manual that comes with your new dishwasher. Installing a dishwasher is straightforward but you want to be sure you understand and are comfortable with the necessary steps.

    When on dishwasher made a funny noise and smoke was coming from it. now dishwasher is dead

    Secure power to dishwasher at the breaker box by shutting off breaker. Some models
    of Hotpoint dishwashers were recalled for electrical problems. The number for the model
    and serial are inside the door on the left. You can Google for recall information.

    I have run across 2 of the new dishwashers with the "square" motor pumps with bad
    castings in the fan section which broke off and lodged in the motor itself.
    On some models the drain solenoid will burn out and produce a nasty smell.
    You can check underneath with the power off to see if the triangle shaped control
    arm moves freely. You can also inspect the motor to see if it has a broken vane.

    If you have aluminum wiring and the dishwasher was connected to it, often the wires
    will work loose from vibration and literally burn a hole through the wire nuts themselves.
    It would be located inside the connection box (Power off first before checking).
    I do not recommend attaching aluminum wiring to a dishwasher for this reason.
    Hope this helps locating the problem.

    Dishwasher stopped midcycle and the fuse is not tripped

    Some dishwashers work the wire nuts loose in the connection box. Especially those that
    are wired to aluminum wiring (these require the purple "IDEAL" brand wire nuts).
    Make sure to secure power to unit before servicing.

    Do you have to install plug on tappan dishwasher? or is it hidden somewhere? Installing new dishwasher and cannot locate plug

    Most dishwashers do not come with a power cord installed. The reason is because some homeowners choose to hardwire the applaince rather than putting a power cord on it and plugging it in. If you plan to use a receptacle, then you need to purchase a three prong power cord. You can find them at any hardware store or appliance parts retailer. The junction box to install it is located behind the lower toe panel directly below the door on nearly all dishwashers. With the toe panel removed, you should see a small silver box. Remove any access screws and open it to find the wires to install the power cord. The color code for installation is as follows:

    Black - HOT lead (120 VAC)
    White - Neutral (0 VAC)
    Green (or Bare Copper) - Ground

    Match the wires to the corresponding colors and attach the ground wire to the ground lug on the appliance. If you have any questions, please post back and let me know. I hope this helps you.

    NOTE: If you are using a receptacle for the dishwasher, it is recommended that it be a dedicated outlet. That is, to prevent overloading, nothing else should be on the same circuit.

    New Bosch dishwasher will not start. Just beeps when you try to start it? Installer is lost as well.

    Check the following specifications if your dishwasher is not starting

    Door switch
    The door switch is important because, if it's defective, the dishwasher won't work at all. To reach it, you need to remove the control panel cover, or sometimes the interior liner of the door. If it's defective, you need to completely replace it.

    Often the main wiring connection from the house, at the dishwasher, burns and breaks the connection. If that's the problem, the wires must be repaired/replaced as necessary. If that's not the problem, check the wiring to the door switch, the wiring between the door and the lower part of the dishwasher, and the wiring to the timer. Repair any broken, burned, brittle, or defective wiring, using the proper appliance-grade wire and connectors.

    Timer or selector switch
    Although it's uncommon, the timer or the selector switch may be defective. If so, you need to replace the defective part, because neither of these can be repaired.
