    Start with the simple things and work your way from there. You will be
    amazed how many people call a plumber who flips a breaker or simply
    clears a stuck float valve (for $80 minimal fee). If no lights are coming on. First check the breaker to the machine. If
    you have an exposed power source to the machine such as a plug or
    junction box open the box and check the wiring is intact and not rusted
    etc. Take care here and shut the breaker off first. No go so far? Check if your float valve is jammed. The
    valve is a safety feature to stop the machine from over filling. If
    anything gets under the valve it will jam open and stop the machine. Look
    inside the machine on the floor will be a small float valve. Looks like
    a small upside down cup. Lift it and clear anything from underneath. Not the float valve either? Check the door interlock latch. Much
    like a washing machine a dishwasher will only operate with the door
    closed (or when it thinks it is closed!). There is a metal tab that
    engages a switch in the door. This is the same switch that activates as
    you operate the handle to open the door. If it is misaligned it will
    not signal the machine that the door is closed and the machine will not
    operate. You can check this by overriding the locking tab. Put
    a screwdriver in the door latch and press the switch. You should see
    the lights come on and power flow to the machine. Note: if the machine is in run mode you will get water spraying. To
    fix this problem bend the tab to properly engage the switch. Or if
    necessary loosen the screws retaining the switch and move it to
    correctly align with the tab. Not it? OK now you are into electronics. First
    is quite simple. Some units have an internal fuse to protect the
    control panel. Check that first. Take your time and take care. Turn the
    breaker off. The control panel is screwed in place. Remove the
    screws and gently remove the control panel. Take care not to have parts
    of the door latch fall out or springs drop out etc. On newer units it
    is very simple as it is just a circuit board. Look for the fuse and check that it is OK. Replace if necessary with correctly rated thermal fuse. ======================================================= Do you have water in the bottom of the machine? Power is there, lights are one, seems to want to work. Water will come in but will not drain. A
    small amount around the drain is normal for some machines. This is held
    to keep the pump primed in some units. However it should not fill the
    bottom of the unit. You know what it normally looked like so it if is
    full then you probably have a jammed float valve as above or a clog in
    the drain. Drain clog. Remove the cover from the drain in
    the bottom of the dishwasher. They usually lift out or have a few
    screws holding them down. Simple to figure out just take your time and
    try not to force anything. Look for a clog and clear if necessary. Your
    drain can run either direct to the drain under the sink or to the
    disposal unit if you have one. The drain can clog at either point. Check
    by disconnecting the drain line from the dishwasher where if connects
    to the sink or disposal unit. Look for a clog and clear if necessary. Water
    exits the machine via the drain pump. If it is not operating the
    machine will not drain. It will fill usually to the point where the
    float valve lifts and does its job by stopping the machine before if
    floods your house. If you have water in the machine to the point the float valve is lifted then drain it out first. Your
    machine should be running now. Lights will come on and it will run
    again to the point where if fills with water and trips the float valve
    again. If so then check the pump and timer (see also timer below). Remove the units as per below. If your pump is belt driven check he belt (very few have belts). If
    direct drive switch the unit on and let if run to the drain cycle. If
    the pump does not come on check for voltage at the pump during the
    drain cycle. If you have voltage replace the pump. If not it is the
    timer that is faulty (see below). --------------------------------------------------------------------------------------------------- OK now your are getting to some deeper issues. Not necessarily hard but only go here if the simple things are OK. If
    you are not getting water into the unit but you have lights on and you
    hear clicking and the timer runs and things are trying to work then we
    know you have power and the timer is running. No water coming to the unit. Make sure nobody shut the supply line off. There should be a tap under the sink on the water supply line to the unit. Turn the unit on an listen at the base for a click as the water supply solenoid (electric switch) opens. No click? Check
    the solenoid. Remove the machine from under the counter. There will be
    screws holding it to the underside of the counter. You may have to
    lower the legs to get it out. They turn with a wrench to lower. Under
    the unit where the water supply line comes in is a solenoid switch it
    opens to allow the water to enter the machine. Water comes in under
    household pressure (it is not pumped in by the unit). Chances are it is
    faulty. Replace it as it can't be serviced. Still no luck? The
    unit is guided by a timer. The timer tells the machine what to do and
    for how long. If it fails the unit will stop or jam in one cycle. If
    you have a physical switch the you turn to select the type of wash
    cycle check it. If you are all touch control then replace the whole
    board or machine. To check the switch open the control panel
    above and use a voltage tester to see if you have current at each cycle
    point. Cleaning sometimes helps if not replace. Hope this helps you. Please rate this tip for me. Adrian

Connector to the faucet for GE Nautilus portable dishwasher

We just bought a used version of the GE Nautilus and we were able to get a generic "fits most portable dishwashers" adapter and it worked great. We went to Fred Meyer (which I believe is a Kroger company in the NW) and it was the only one they had. It only cost $3.99. The brand is Plumb Craft by Waxman and the model number is 76-127. Dishwasher Faucet Aerator. Hope this helps!

Good Luck!

sounds like the water outlet has a leak - probably a simple 'o'ring problem - these can wear.
