Hi, welcome to Just Answer... Error code you have highlighted is E:15 (looks like a mirror imaged 3). Error E:15 indicates water leaking through dishwasher base or flood switch activated.
As a quick fix I would suggest you to unplug the dishwasher from the mains or reset the dishwasher's circuit breaker. If it is integrated dishwasher then you will need to pull out the dishwasher and tip the dishwasher forward with an angle of 45 degrees. Be aware there would be lot of water on floor once you tip it, so, make sure you have few towels handy with you.
If the condition still appears after a cycle or two then your dishwasher might have developed a leak in the base.
Let me know how it goes. Cheers!
Apologies, I thought it's E:15. You would need to help me answer few questions please before we conclude what/where the issue is.
When you start the dishwasher does it try to fill in or drain?
Is there any unusual sound when you try to switch it on?
Were there any error codes off late like E:1 or something?
To reset the control press and hold the start button for more than 10 seconds.
I see you have raised a second query for the same issue.
The numbers on the display are a time not a fault code, this suggests the timer on the PCB has failed.
A new PCB can be found here for around £70, please note the model number supplied had a typo and is actually SMS63M42GB/B5.
Please let me know if I can be of any further assistance.
