well #2 and well #4 said low water but was full, now both dont get hot just stopped working I have a Vollrath warmer #71001, the water temp is actually higher than the knob setting. Is there a way to calibrate the thermostat or do I need to replace it? Thanks cutting blades for the fry cutter Need to find out what year unit was made Please answer asap just need to know what parts to replace thanks. We have custard machine model CC303A. Every night we have to clean custard out of the back of the machine because it leaks in there from either the hoppers or barrels. I can't seem to find which part I need to replace... The 2 Elements have 240v to them. Fans are running. Timer and thermostat status lights on.
