Question about Bosch 24 in. SMU40 Built-in Dishwasher

Open Question

SMU50e32SK dishwasher showing E06 in display after a few seconds. Dishwasher has one Main Power PCB and one control unit PCB in the front. Info: Main PSU PCB has been shifted due to overvoltage. All sensor checked, seems to be ok after this has been shifted. I don't think the induction motor(big pump) has been affected due to the relays in front. Could it be the Control PCB in the front or maybe the small drain PUMP. Well some of you properly now what E06 is referring to on this model. BR MEM

Warning! To avoid personal injury or even death, always disconnect your appliance from its power source--that is, unplug it or break the connection at the circuit breaker or fuse box--before you do any troubleshooting or repair work on your appliance. Also, because some components may have sharp edges, use caution while working on your appliance.

SOURCE: I changed my water control valve, thinking my

Hi,

There is a simple explanation for this - water is leaking into the bottom of your dishwasher under the washing compartment. This has caused the float to rise and trip the switch which activates the Aqua-Stop / anti-flood protection system. This also closes the solenoid (water control valve) which explains why you thought it needed to be replaced.

The only way to check this is to remove the washer from under the counter (disconnect power and water supply first) and tilt it backwards about 15-20 degrees. Water should run on to the floor from under the washer so I suggest putting some old towels down first. Once the water has been drained from under the washer, you can use it again, but it's not advisable if you have a leak. The only way to find the leak is to get access to the bottom of the washer by removing a side panel, usually the right-hand one. As you already replaced the solenoid, you should know how to do this. Once you have access you can run a cycle and try to see where the water is leaking from or you may be able to see signs of corrosion somewhere which should help you to identify the source of the leak.

If there is no water under the washer, you probably have a faulty float switch or possible a faulty control module.

Hope this helps. Post back if you need further assistance.

Regards,
BElectric

Error code 6


Good Morning sewblessed - Generally, error code E06 means that when the unit is in the dry cycle, the control does not receive the proper speed feedback from the lower fan. One of the best ways to determine if this is a false error code is to reset the power to the appliance by either unplugging it or flipping off the breaker for about 30 seconds. If the error code persists, then more than likely the lower fan will need replacing and I would recommend connecting with an experienced appliance repair tech to assist further.

I have a Bosch SHU9955US/14 (Integra) dishwasher. There is currently a 0 with and asterisk showing on the display and the unit will not run.


see this causes and fix it. God bless you
Thermal Fuse If the dishwasher won't start the thermal fuse might have blown. The thermal fuse helps to prevent damage to the dishwasher by turning off power so that it doesn't overheat. Once blown, the thermal fuse will have to be replaced for the dishwasher to work.

Door Switch The door switch, or switches, are sometimes called interlock switches. The door switch prevents the dishwasher from running while the door is open. If the dishwasher won't start, the switch or switches might be defective. To access the door switches, remove the control panel or inside door panel - depending on the model. They can be tested for continuity.

Main Control Board The main control board provides power to nearly every component of the dishwasher. If the dishwasher won't start the main control board might be defective. YOU should first check for more common parts. Many times control boards are replaced unnecessarily because the problem was not diagnosed properly.

Touchpad and Control Panel If the touchpad is defective, the control board might not get the signal for the selections made. If the dishwasher won't start and the display doesn't seem to change properly when the buttons are pressed, the touchpad might need to be replaced. On some models the touchpad and control panel are sold together and will need to be replaced at the same time.

Touchpad If the touchpad is defective, the control board might not get the signal for the selections made. If the dishwasher won't start and the display doesn't seem to change properly when the buttons are pressed, the touchpad might need to be replaced.

Timer The timer allows power to flow to the proper parts at the proper times. If the dishwasher won't start, the timer might be defective. Keep in mind that timers are often misdiagnosed as the cause of a problem. Check other components first before replacing the timer.

Fisher and Paykel DS603 no power


Hi,

There is a thermo fuse in this unit and it can cause the controller not to power up. It is located on the heater plate, if the unit got too hot this will cause this fuse to blow and cause not power to the controller to a singe drawer unit only, this would not shut down both drawer though. This fuse is not replaceable other than replacing the plate itself. Get back to me if you need part numbers and I can get them for you or you can call Fisher and Pakel directly and they are 24 hours a day service call center. The plate is tricky to replace and you will have to change both seals at the same time, not real pricey though.

I hope this helps, keep the unit, its a good dishwasher.. Good Luck

Hi

First make sure that nothing is blocking the drain pump assembly located inside the lower front panel of the dishwasher. If the issue returns after its cleaned then try to reset the dishwasher control by pressing the HEATED DRY button and hold it for 15 seconds, if its still not resolved then it means that the control board has gone bad and should be replaced. Hope this helps...please post back for further assistance.

Had a power failure from bad weather now the dishwasher is dead? checked the fuse box the breaker is fine, there are no lights on the display panel. what is the reset procedure for this dishwasher?


Try turning the breaker for the dishwasher off for 30 seconds and turn it back on. This should reset the dishwasher control board. If it still doesn't work then most likely the power failure burned up the main control board. The control boards in the newer dishwashers are sensitive to any type of power surges or failures.

Hope this gets it running for ya.

LG LDF6920ST Dishwasher won't start


With nothing displaying and only the humming sound, it appears that the main controller card (PCB) has most likely failed.

If it were my dishwasher, I would add a pitcher of water (more than two big glasses full), close the door and start a cycle and listen at the drain. The first thing a dishwasher does is run the pump to empty any standing water before it fills up. If you hear that water drain, (and can see that is has drained from inside the dishwasher) it is not as broken as I think it is.

BUT, this dishwasher should be displaying something from the moment you press the power button.

Please post back with what you find and decide you do. OK?

GE Profile PDW7880G00SS Dishwasher will not Start


Re: My dishwasher start light flashes and the timer display is blank.

That is a fault condition, if the display is blank it is probably a faulty control board.

Unplug the appliace from main, or trip circuit braker to cut power for ten minutes.

If display is still blank on startup, then replace the timer control assembly.
