1 CVA 615 Gearbox Replacement; Brew Unit Presence Switch,
Check for Proper Wiring
When replacing the gearbox in a CVA 615, you should confirm that the brew unit
presence switch is wired correctly. Some reports from the field indicate that this
switch may be miswired. The switch is 'normally closed', meaning there is continuity
when the brew unit is absent. Inserting the brew unit actuates the switch and opens
the circuit. The photo below shows the correct physical wiring.
Alternatively, you can check for continuity at the JP34 connector; you should read
zero ohms (continuity) with the switch at rest (no brew unit installed) between the
black and yellow wires.
