My chip blaster recently stopped working. It pumps coolant through the tool. A couple months back we cleaned the system. The alarm kept going off and red light blinking telling me to change filter. We changed both filters again. Now the level in its take is low and the pump doesnt come on at all. I want to be able to trouble shoot it. Not sure if a saftey might have it off or what else it could be. I still got power and leds lit inside the door . But i am not sure what to look for as far as switces and relays . Does anyone by any chance have some pointers in troubleshooting these?
