How to repair Sunbeam Minibarista EM4300 coffee machine: pump won’t stop!

This Sunbeam Minibarista EM4300 coffee machine has a fault: its pump won’t stop pumping water. Even when powered off! This video shows how I took it apart and found the problem. It was cockroaches inside the machine shorting the pump controller! I successfully fixed it and it’s now working making coffee again.

thanks for the video. Helped me figure out how to get it open.
Mine was behaving the same way but no sign of any burning when opened up. replaced the triac and it's working perfectly again

can you give me a hand bro i have a mini barista 125v, i always mess around with it by opening and cleaning the lines but last time i didn't descale my machine for over 7 moths (the steam wand was clogged) and when i finally did used a good descale i heard a different sound, in the end the steam wand came back to live but now then i press the single or duo shot the water comes out the head group and also comes out the steam wand. i did descale other 3 times and all the lines are pretty clean but i think the sensor is damaged or blocked but the thing is, i have no idea on how to check that out
