Bosch dishwasher leaking from bottom back panel

I have a Bosch dishwasher that I absolutely love. It’s a beast and cleans so well but it has had a few leaks that I’ve had to repair:

1.) Water inlet valve 2.) Heat pump 3.) Sump assembly

I have a new leak and finally located it underneath, along the back plastic panel (pic 1) After a tonne of googling the only repair I’ve seen for a similar leak is using Kason 3700 series food-safe silicone sealant along the interior tub seal at the back (pic 2). Is this my only option or is there any other way to replace parts to repair this leak? Any advice anyone could provide would be greatly appreciated.
