Dishwasher won't start


Try resetting the unit by shutting off the circuit breaker first for 1 minute then try the reset button. If nothing happens, then i would recommend having someone take a look at it.

Latch on dishwasher was broken, we replaced it with new latch from Maytag store, after we assembled new latch the dishwasher would not work on start, all lights would work, only start button would not...


You'll need to check the ribbon cable between the keyboard and the circut board and any switches controled by the latch which is more likely the problem.Also look for a loose wire on or near these switches.
Good luck,

F5e1 error code


The F5 E1 error message indicates the latch motor was unable to lock the door. When the self clean cycle is started, the control board will turn on the latch motor which is mounted on the rear of this range. The motor is connected to a cam that transfers the motors motion to a rod that runs under the cooktop. This rod connects to the actual latch mounted behind the oven door. The control board will then monitor a position switch that is actuated by the latch motor cam. As the motor rotates, the latch will engage the door locking it in place just as the cam contacts the switch button. When the switch contacts close, the control turns the latch motor off and starts the cleaning cycle.

img_5123.jpg
When diagnosing this failure, the error code gives us a good starting point to begin our trouble shooting. I removed the rear panel and started a clean cycle. Once the start button was pressed, the latch motor began to rotate, but didn't stop at the locked position. It continued to rotate three times and then displayed the error. I unplugged the range from the wall and using my meter, did a continuity check of the latch position switch (the one on the right). The switch was reading as an open circuit in standby and when I actuated the switch which tells me the switch has failed. The second switch on the latch assembly, by the way, is to turn the oven light off during the self cleaning cycle to protect the bulb. That way, if you leave the light switch on the control panel turned to the on position, that second switch will turn it back off. Good to know if you can't figure out why the oven light won't turn on.

With the failure down to the latch assembly, I checked the range parts to see if the switch came as a separate piece, but it looks like it's an entire assembly, and not individual parts. I removed the old latch after removing the two screws and six wires, then installed the new latchshow?id=y6f3ez5blva&bids=92089.709229668&type=10&subid=. Once all the wires were back connected to the proper terminals, I put the rear panel back on and plugged the range back into the outlet. Started a self clean cycle, but this time I heard the motor make one revolution and stop. The cycle started for the customer and a few hours later, I am sure the oven was nice and clean.

I have a KitchenAid KUDSFLxxx dishswaher - a couple of weeks ago it stopped working (looked dead) - I took the door apart and tested the switches in the door latch - tested good - started playing around -...


Hi


If you have replaced the control panel then it is the electronic control board that is bad and should be replaced. If you have replaced the electronic control board then check the door latch, it can be due to the latch & control not operating. Hope this helps...please post back with its model no. for further assistance.

No power not coming on. circuit braker is not kicked.


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.
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 ?
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.

It will not start


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?

Dishwasher won't start. circuit breaker not tripped, no reset button where wire connects, fill-level float not stuck in up position


According to what you are writing, it leads me to believe it is the latch switch is broken. As long as the machine believe the door is not latched closed it will not attempt to start anything.

4. Motor (inoperative, check resistances).
5. Door switch (open contacts).
6. Door latch not making contact with door switch.
7. Touch pad circuit defective.
8. No indicator lamps illuminate when START or OPTIONS is depressed.

When you start a cycle the washer fills then turns then sounds as though its trying to empty the door lock light flashes and 2 other display lights flash


It means your door is not shutting or latching

Check for debris and nothing stopping it from shutting

If not replace door latch(some parts lists call it door switch)

its most likely not actuating so it wont advance to the next part of cycle.

if not latch could be bad control board, id try latch first is cheaper and more common
