SOURCE: TH-79A Blank screen. It works with "F-switch on" but then goes blank.

Happened to me too. It takes some disassembling!!!! Between the screen and the underlying circuit board is a rubber strip with conductive material throughout which provides ''ground' for the display. This rubber wears out over time, but the quick fix is to turn it a quarter after cleaning and treating the contact surface with 'contact spray'( sparsely!!).

Job requires steady hand and pincers.

Hi.

At a glance it looks like an electronic control board problem, what you are describing is not an error code.

Try first disconnecting power, either tripping circuit breaker, or unplugging the power cord. Keep the machine disconnected for a couple of minutes.

If that does not clear the error, try holding down the start button for six seconds, until the panel reset.

If still no luck , then the electronic control may need replacement. The part must be tested by a technician. A control assembly is expensive, and there are more parts that can cause the electronic timer to jam.

If you need to call a techncian or to buy parts you can ring the number listed on the owners manual.

Try first the reset procedure described at start.

Regards.

Hello,

Welcome to FixYa.

Based on your description
I'd say the issue actually is with the control...unfortunately. This is commonly associated with a heating fault on Bosch built dishwashers ( various models including Bosch, Thermador, Siemens, Gaggenau, and Neff ).


Since the issue is likely within the electronic timer/control, specifically the heater relay solder joint. ( a faulty flow switch, ntc or heater can also cause this, but not very probable ).
These are the steps you'll need to follow to resolve it or at least investigate.

If you feel capable of checking this on your own, there`s a way to visually inspect the control yourself...it really isn't very complicated.

It will require you to remove the control from the unit and then remove the control from it`s plastic housing and look for a burnt solder contact on the printed circuit board.

The culprit will 99% of the times be one of the pins from the heater relay,

**Flip this over and inspect the solder joints, it will be obvious when you see it.**

This ones new, but it's where to look...

...hence the unit sit`s and takes longer & longer to finish because it can`t heat to advance or unless the 2 buttons for "cancel" are pressed...this can also manifest as a long cycle time as I mentioned and eventually display's "1" on units with a display and usually very poor cleaning, no heating ( don't be fooled by the homes inlet hot water temperature ) as a result.

You can also run the unit through a regular or econo cycle ...any cycle with the exception of rinse & hold, and with the door panel removed place an ammeter on the gray/black wire it should draw 11 amps during the wash cycle...after it fills and the flow switch indicates it has adequate water to engage the heater.

i.e. ( this may differ from your specific model, but the same rules apply )

**My Opinion - if you or someone you know is proficient at soldering, a lot of times it can be remedied by simply repairing the solder...but it has to be done well...or it will not last.
Bosch recommend`s replacing the control and I don`t pretend to speak on their behalf nor do I profess to know better. This is just my experience (it work`s) and my opinion (why buy new if one can repair ?)**

**Please disconnect the power or turn off the breaker before attempting any service to the dishwasher.**


If you do not feel comfortable attempting this service, call a local pro, preferably one familiar with Bosch/Thermador/Gaggenau/Siemens, to service your machine.

Thank`s for visiting "FixYa" for your repair inquiries. Please take a moment and rate this solution to it's helpfulness.

Good luck.

Cycle time remaining isnt displayed on Frigidaire Professional dishwasher


From my research, this unit is not designed to show it while in use only if stopped during a cycle or if a problem persists within the unit to cause a pause or error code to display.

My bosch dish washer won't work. A number 1 is displayed on the electronic panel. what does this mean Paul


Helloduranjp,
Welcome to fixya.

You said, Your Bosch dish washer won't work. A number 1 is displayed on the electronic panel.

If it is displaying"01" then that means the extra dry setting is being applied!
Did you try to use the extra Dry setting?
Did the dishwasher work before this or is it brand new?
What is the model number and year?
Let me know ! I'm waiting for your response

Below is and example of the usage of 01 or 00 in a Bosch Dishwasher!

Extra Dry Heat
With this option you can raise the temperature of the rinse water and increase the drying
time which will result in improved drying.
To activate :
Press and hold the left cancel drain button ,
Then press and hold the on/off button when the LED display shows a, "00" or a "01"
To enable the additional drying heat,press the left cancel drain button until the LED display shows a "01"
To disable the additional drying heat,press the left cancel drain button until the LED display shows a "00"
press the on/off button to save the settings.
