Dishwasher took 3 hours to complete cycle

If you have set the unit to heated water or your hot water is not hot will delay the wash cycle. The heater in the dishwasher is very slow!
The following is from the user manual.
First try the solutions suggested here and possibly avoid
the cost of a service call...
Dishwasher is not operating properly
Dishwasher does not run or stops during a cycle
Is the door closed tightly and latched?
Is the right cycle selected? Refer to the "Cycle Selection
Is there power to the dishwasher? Has a household fuse
blown or circuit breaker tripped?
Has the motor stopped due to an overload? The motor
automatically resets itself within a few minutes. If it does not
restart, call for service.
Is the water shut-off valve (if installed) turned on?
Dishwasher will not fill
Is the overfill protection float able to move up and down
freely? Press down to release.
Dishwasher seems to run too long
Is the water supplied to the dishwasher hot enough? The
dishwasher runs longer while heating water. Refer to the
"Dishwasher Efficiency Tips" section.
A delay automatically occurs in some wash and rinse cycles
until the water reaches the proper temperatur

Hope this helps?

Nor filling with water and making a noise

Please review your Owner's manual troubleshooting section. No manual? try MFG website, or email their customer service, or try
I would guess there is a problem with the water fill valve, or the control of that solenoid valve. There are several "appliance parts" stores online that may be able to help with diagnosis and repair parts needed.

Low humming noise coming from the dishwasher when start no water going into machine?

First you will need a tester , that has 120 volt setting remove the lower cover and you should see a water valve sometimes they put them in the back of the unit also , but always near the floor, with this unit plugged in and unit turned on so that it should be filing with water, check the wires on the water valve to see if you are getting the 120 volts , if you have the power but the unit is not filling the water valve is bad , if you dont have power at the valve then the timer or door switch is bad this is all there is to this unit , I bet on a bad water valve here is a place to get parts and as always be careful when worjking with unit with power , if you need to replace anything turn main power off before seviceing unit , I have found several washers the water valve wa sjust fill of dirt , cleaned it and it worked just fine , if you need parts go here , email me at

I have a new world dishwaser flashing e4 what is the problem

you can troubleshoot your dishwasher by
  • First check the manual to see if the machine has a specific troubleshooting guide.
  • Note all sounds or other symptoms the dishwasher shows.
  • Look for some of the more common problems. This includes water temperature deviations, poor washing, failed motor, overflows or leaks or door-latch problems, among others. Anything that can't be dealt with through your troubleshooting guide needs the use of a professional. Check for obvious causes, like blockage in any area or extremely dirty situations affecting water flow

  • you can also always troubleshoot your dishwasher by :

    Instructions Things You'll Need:
    • Dishwashing Detergent
    • Scrub Brushes
    • Steel Wool
    • Steel Wool
    • Screwdriver Sets
    1. Make sure the cord is plugged in and that the breaker hasn't tripped.
    2. Be certain that the door is completely closed and latched.
    3. Check that the cycle button is pushed in all the way.
    4. Check the sprayer arm and filter screen at the bottom. Are they obstructed by a loose piece of silverware or a plastic lid?
    5. Unscrew the cap holding the sprayer arm on; pull it and the screen beneath it out. Use a wire to poke obstructions out of the sprayer arm holes. (Don't use a toothpick because it could break off in the hole.) Scrub the screen with a scrub brush and a little bit of dishwasher detergent.
    6. Eliminate the following as sources of noise: low water pressure keeping the dishwasher from filling, dishes rattling against the sprayer arm or other dishes, loose items tumbling around or trapped in the bottom of the unit.
    7. Take apart the front door panel according to the manufacturer's instructions if the detergent dispenser isn't opening. It may be corroded or have a broken timer lever. If this is the case, rub the corrosion off with steel wool or replace the lever according to the owner's manual

    SMU2046UC: waste water won't empty. Wash cycle works like it should but waste water remains in the bottom of the dishwasher. Sounds like pump is humming and there don't seem to be any clogs in the system??

    Most likely a blocked pump. You should be able to access the pump from the base of the unit under your filters. Remove the cover and rotate the pump impeller to free blockage then start any prog to check if pump is working,if OK reassemble, if not replace pump

    Wont drain hear clicking noise


    If the water doesn't drain from your dishwasher, check these:

    Drain line/air gap A clog in the drain line or air gap (if there is one) is the usual reason that a dishwasher won't drain. Often the problem is at the point where the drain line attaches to the garbage disposer or household drain line. If you remove this line, you can clear any debris from the hose or hose connection. Be sure to reattach the hose before starting the dishwasher again.

    Pump Your dishwasher pump ejects the water. The pump is usually mounted directly to the motor, then attached to the bottom of the dishwasher. You can reach the pump from inside the dishwasher, but first you need to remove the lower rack, the spray arm, and the spray arm support.

    Look for an impeller--a round plastic fan blade-type of device that spins around. This is the wash impeller, which forces the water through the spray arm. Beneath the wash impeller is the drain impeller, which is similar in size and shape to the wash impeller. The drain impeller pushes the water toward the drain port. These components make up the pump. If any of the pump components are defective, you need to replace them.

    Drain valve and/or solenoid Many dishwashers use a drain valve with an electric solenoid. When electricity flows to the solenoid, the valve opens and diverts the water to the drain. Sometimes the solenoid, or the diverting lever, sticks and prevents the dishwasher from draining or filling properly. Try to free up the solenoid to lubricate the lever. Otherwise, you may have to replace the solenoid or pump assembly. With these systems, the motor always rotates in one direction. When it's energized, the drain valve diverts the water.

    Other dishwashers simply reverse the direction of the motor to drain the dishwasher. These units don't have a drain valve. Instead, there's a drain hose connected directly to the pump housing.

    Belt One brand of dishwasher uses a belt to drive the pump. If this belt is broken or has fallen off, replace it.

    Motor If the motor isn't turning or working, the unit won't drain. First check to be sure you have power to the dishwasher. If not, see the section "It doesn't work at all." If the motor hums but doesn't turn, it may need to be replaced.

    Some dishwashers are susceptible to getting stuck if you don't run them regularly. If you haven't run the dishwasher for more than a week, you may need to manually spin the motor to free it up. If the motor is defective, you need to replace it. Dishwasher motors can't be serviced.

    Timer Part of what the timer does is control the motor and drain valve. If the timer doesn't work properly, the water may not drain and you need to replace the timer. This problem is uncommon.

    I am looking for a wire diagram for a bosch dishwasher mod# smu2046uc/14 ser# ? fd7609 470358 can you help me


    Despite the magic it performs in the kitchen, a dishwasher is actually quite simple--it is essentially a watertight box that sprays dishes with hot water and soap, drains out the dirty water, and then dries the dishes.

    Hot water is delivered through a supply hose that connects to a valve that controls the water's distribution to spinning spray arms.
    A pump gets rid of the dirty water, and an electric heating element dries the dishes. All of this is operated by controls that may be very simple or quite complex.

    Siemens hydrosensor dishwasher SE25A091GB/22


    If you are still trying to sort out this issue try the following.

    From what you say then it is most likely the aqua sensor on the side of the dishwasher. The gurgling sounds that you hear are likely the drain pump running and the un-drainable water sloshing in the sump.

    Verify that there is actually water going to the dishwasher( Basic step but often overlooked)

    Next the inlet valve will have to be checked. This is the part where the water line from the house connects to the dishwasher, under the toe/kick panel. Remove power from the dishwasher. Disconnect the dishwasher electrical connections (2 wires) to the inlet valve and connect it (carefully to 110 V power) using a jumper wire. With 110V power the valve should open and water will flow into the dishwasher, if not then the fault is in the inlet valve.

    If this checks fine then the fault is likely in the aqua sensor...

    On the outer left side (viewed from front) there is a panel, Behind this panel there is a small clear(of light blue) plastic mechanism with hoses and wires attached( There is usually a yellow disk at the top about 6cm in diameter) this is a float and sensor assembly there is tells the control the water level and works as an emergency drain if there is an issue. There will be a red stick protruding downward to the base and a Styrofoam float on which the stick rests. This is a pan overflow sensor if the stick is too high the unit will go into drain and cut off the fill valve power. The yellow disk is a diaphragm which senses water height. This unit can become stuck with wear and hard water.

    I know sounds stupid, but I must ask: Are the water supply valves turned on? Is the water supply pressure good?

    A pump usually isn't found on the inlet side. Most such appliances have sediment screens located in the water inlet connections. These will sometimes get blocked with sediment such as lime, for example. Otherwise, you may have a defective controller or defective solenoid. Most units have two solenoids (hot & cold). The solenoids are located at the water inlet hookup (the screen is usually a part of the solenoid). When the washer is started, a metallic click should be heard from the solenoids. Beyond checking the screens and water valves, a repairman should be called in, unless you're skilled with a voltmeter, electrical troubleshooting, and appliance disassembly.

    BTW- is this a new installation or has the unit been in service for awhile?

    Good luck.

    Indesit D41 dishwasher problem

    you need to check the inlet walve . when you start the unit you say it drains. so after the drain do you hear the water entering the dishwasher? If you hear a sound like a buzzing noise that would be the inlet valve working. if thats the case there is a clog at the screen in the valve not allowing the water or enough water in the tub. seeing that this is a portable unit you will also want to check to make sure the fill hose is not kinked up anywhere in the cabinet or under neath the dishwasher. If you hear no buzzing noise you need to check the inlet valve with a meter to first make sure your getting power to it and that the valve itself if good. check these things out and let me know what you found and we can go from there
