Start button does not work, cancel button gives life but no actio

Six years is about the life of a dishwasher.

Reset the dishwasher by pressing and holding the "Start" button for at least three seconds. Depending upon the Bosch dishwasher model you have, you also can push the "Cancel-Reset" button to reset the dishwasher. Select a new cycle and press "Start."

this is not from me but i found it and am passing on..
Hi


Thanks for using FixYa. Error code 4h means 4 hour delay start which means that the dishwasher is in delay start mode and has been set to 4 hours. You can either wait for 4 hrs or to start it immediately press the cancel button to cancel the delay start option. After this program the cycle and options and press Start again as the dishwasher will not start the wash until it reaches the delayed hour i.e. till 4hrs. If after 4 hrs still the light blinks and it wont start then you'll have to replace the control panel. Please do accept the solution if the issue is resolved or post a comment for further assistance.


Thanks

have a service technician in as it appears to be a problem in the program board
could be moisture across the circuit board

The cancel light is on because the cycle maybe paused or canceled. The lit red button should say Cancel/Drain. If you already tried to press start and if it won't finish the cycle then try pressing the Cancel/Drain to drain and start over.

• Find the "Start/Cancel" button on the dishwasher's control pad. This button is located on the far-right side of the pad on most Frigidaire Gallery dishwasher models.
• 3 Press the "Start/Cancel" button to clear the "PF" error code. Resume using the dishwasher as normal. You may have to reselect and start your cycle from the beginning.
  

START/RESET status indicator light flashing

You have pressed the indicator light flashing START/RESET pad while the START/RESET dishwasher is running. This will cancel the cycle. The light will stop flashing after the dishwasher drains (about 90 seconds).

• Press the pad once to start the dishwasher. Press the pad a second time when the dishwasher is running only if you wish to cancel the cycle.

Power to the dishwasher was turned off while a cycle was running and power has just been restored to the dishwasher. The blinking lights indicate that the dishwasher is draining the potential water inside.

• The light will stop flashing after the dishwasher drains. A new cycle will start automatically.

Good luck

There was soap particles caught under the float valve. Thanks.

I have had the same problem with my dishwasher. I.e., the buttons don't respond (no LED) when you press them. Only the "Cancel/Drain" light works and the dishwasher reacts to cancel/drain. I found a diagnostic in the kick panel that has you press; "heated dry, normal, heated dry, normal" within 6 seconds and the washer goes through a diagnostic. All of the tests perform as they should and at the end the washer works again. I don't know why unless doing this resets the circuit board. Does anyone know?

Sounds like the electronic controls (smart card) are acting up. Try shutting off the power at your fuse box or shut off the circuit breaker for 1 minute them turn the power on again. This fix quite often works on electronic appliances.
