How do you replace the fascia on a Beko dishwasher DSFN 1530 S

if doesnt feel same as other buttons bad button replace

before you can remove the top panel you have to remove the front outer door panel, there are screws down the sides to remove it.

I think you have a control board fault, this is the part that is connected to and part of the buttons.

Open up the cabinet and check the water supply hose to the spray head, it may be kinked or clogged.

Could be the door interlock switches. There are usually two of these. I removed them on my GE and replaced them with an illuminated push button kill switch.http://www.auberins.com/index.php?main_page=product_info&products_id=360
When switch is on the control panel is powered up as well as the rest of the unit. If you need to add a dish after activation you just push the button before opening the door and it interrupt the cycle which resumes with another push.

We have the same problem. How did you resolve this issue?

first make sure that power is coming in by checking connection with multimeter.If there is power coming to where it is wired up then the problem maybe the handle swtich either burned out or not making connection when the door is closed

The usual cause for dishwasher tablets failing to fully dissolve is a failed dishwasher heating element.
