Hi pahttch,
out of security concerns the plastic pan (p. nr. 215-11 and 215-12)
should be replaced asap!
In the document “Tips from Mark” you can find an emergency repair method,
plz scroll down to General tips, point 3.

If you want to repair that by yourself I’d recommend to select your source carefully - some dealers offer this part for exorbitant prices
