My Starbucks Barista is tripping the GFI switches and I suspect it may be the heating element has a voltage leak to the rest of the machine - how can I use the continuity test to determine whether or not there is a problem? What two end points should I measure?
I've measured the following:
A. between (1) the hex screw below the red cable L-bracket of the heating element to (2) the machine's chassis - and there's continuity, the meter reads 3.7 ohms
B. between the L-brackets on the heating element, (1) the red and the (2) grey cable connections , the meter reads 19-20ohms
C. between (1) the hex screw below the red wire L-bracket and (2) the hex screw below the grey cable 4.5 ohms
Great tutorial. Thank you. Would you happen to have links to where we can purchase spare parts for the machine?
