The control panel works intermittently.

First, confirm that the dishwasher display is working. If the display is still working, try pressing some of the touchpad buttons. If some of the buttons respond correctly but others don't, it is likely that the touchpad is at fault. (Some manufacturers sell the touchpad separately from the control panel. Other manufacturers require that you purchase the touchpad and control panel together. If you cannot replace the touchpad individually, replace the touchpad and control panel.)

Check your owner's manual and make sure the child lock settings are turned off. Reset the dishwasher -If your dishwasher won't start but the lights are on, there could be an issue with the start button.

If the dishwasher is working but you get no response when you press the control buttons the reason for that is probably either a faulty touchpad, faulty control panel or a main control board.
Touchpad and Control Panel: If some buttons work and other don't it is likely that the entire piece needs to be replaced. It depends on your dishwashers make and model if the touchpad and control panel are sold as one unit or separately.

Good luck

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. The thermal fuse is usually located in the control panel on the control board or mounted to the bottom of the tank behind the lower panel. The thermal fuse can be checked for continuity.

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.

Hello,
You will need to replace the touch pad assembly. You can purchase the part from the link below.

You can read an article that explains how to make this repair yourself at the link below.

Your F1 error is
: indicating an electronic control malfunction
: (a $250 part) or a control panel (a $60
: part)? Usually if the symptoms stop with the touchpad disconnected from the clock, that touchpad is often the cause. If the error continues even with the touchpad disconnected, the clock itself is usually at fault and will need to be replaced to correct the problem. On some models it is not possible to disconnect the two in which case the electronic control/clock would have to be replaced regardless.
There is a tool that allows testing of the touchpad (on models where they're separate parts) but is kind of expensive for a homeowner to purchase them self. If you contact a technician so equipped, they should be able to test the touchpad before replacing any parts.
BTW. On most models, the control keypad is only sold along with the whole control panel (without the electronic control) but on some models the keypad linked below can be used to repair the one on the original control panel.

If you do have the Touch Control Electronic Pad, then you do have a problem, moisture related. You need to open the panel, use a Hairdryer to dry the panel properly and replace. This sorts many of these Touch Control Electronic Pad.
