Error CodEs
Curtis Ads digital systems contain various safety features in the electronic circuitry that will shut down the
functions of the unit in the event of system failures. Error codes are signalled by the red rEAdY-To-BrEW
light blinking.
inTErprETing ThE CodEs
Ads technology features a state-of-the-art Error Code system. This is designed to quickly advise you of any
problems the system may experience expediting service or repair. occasionally an error reported may be a problem
with the water supply or electrical power, noT directly associated with a fault of the Curtis system itself. An example
of this includes:
• Clogged Water Filter – indicated by a Water level Error Code
Error Codes are indicated by
rEAdY To BrEW
= long Flash = short Flash
Error Codes can only be reset by turning the rear toggle switch to standby for a minimum of 10 seconds, then returning
the switch to on. Any service required for your Curtis system must be performed by a qualified service technician.
