I tried to run the dishwasher and it won't. It just says 1h on the display.

that's not an error code. it's a 1H, as in one hour, the delayed start function. hold the delay start button down to override, then reset it back to where you want it.

1H= 1 hour delay. press the cancel button and then run the dryer with the vent tube off as if it is not drying like it use to then the vent is restricted, note this has nothing to do with the 1H. You will need to clean the vent tube out and you may want to clean the dryer out,also. You will be amazed how much lint is inside the dryer. Good Luck Tim

Hello,

Try unplugging the unit for several minutes if that does not fix the issue you will need to replace the main control board to fix the issue, let me know,

hi heres what i found The 1 H is not a fault code it is the delay time of one hour.

The 1 H is not a fault code it is the delay time of one hour.

I think that the delayed use is engaged.  Wait an hour, and it will probably start up on its own.

The 1 H is not a fault code it is the delay time of one hour.

The part called a Wax Motor (about 2 inches) inside the door is responsible for opening your dispenser.Check it / replace it.
