Hello! I bought a used CW-5000 chiller. It starts up and gives the 3 beeps for the water sensor, but that subsides. However, after about 30 seconds, the machine just shuts down as it pops the fuse inside the power inlet port. The compressor never comes on, and the green NORMAL LED is very faint and pulsing before the fuse blows. The red Alarm LED is bright and properly lit when it is triggered, and the LCD screen functions properly.

I'd appreciate any help on where to look or what to try to keep this machine running.

Thank you!
