S5 printhead completely overflowed

[aag 6]

After an overnight print, the head is now completely filled with toughPLA and Breakaway. I doubt that it can be rescued, but maybe somebody has a suggestion. It kind of printed everything upwards into the printhead. Also, is this to be considered a warranty replacement issue?

I had this happen to our 3 Extended. I returned it under warranty and it was repaired - it's something the machine has done to itself, rather than damage you've caused due to your own mistake.

Whether it is repaired under warranty or not can also depend on the condition of the silicone nozzle cover and on the fact if it was mounted correctly. So regularly checking that one and replacing it if it is damaged not only helps to avoid discussions about warranty but effectively protects your printhead from being flooded. Checking once a month is good for regular PLA printers, if you print materials with a higher printing temperature you may want to check it even more often.

In this particular case the silicon cover was ripped off and torn into two pieces. How that exactly happened is unclear. But talking about the silicon cover, I find that the mechanism that should keep it in place is very clumsy and unsafe. I do not understand why UM couldn't engineer a more stable and more easily serviceable cover.
