If WTR FAIL light is flashing:
Ensure water supply to machine is turned “on”.
Reset machine power “off” then “on”.
If THERM FAIL light is flashing:
Reset machine power “OFF” then “ON”. If green ready light does not turn off after 10 seconds then:
Check thermistor connections.
If connected properly, replace faulty thermistor. (Mineral build-up may be the cause.)
WTR HEATER light will flash on and off when the water tank is being heated:
Note: When green “ready” light on front of machine is “Off” WATER HEATER light should flash.
If light works properly and machine is not heating, replace faulty heater. (Mineral build-up may be the cause.)
If POWER OK light is off:
Make sure power switch is on and machine is plugged in.
If switch is on, and light is off, call factory for assistance.
Note:
PIC 4/5/6 - If water gets cut off to machine for 5 minutes during operation, tank water will not replenish, heater
circuit will be disabled, and heads #1-3 will be disabled. Other heads will still operate. Left controller will read
“WATER FAIL”. What could happen is that other heads will dispense low or no water (possibly cold) and full amounts
of powder.
Note:
PIC 4/5/6 - “Thermistor Fail” - When the thermistor reads out of range or is disconnected, the machine shuts
down the dispensing and heating. Only heads #1-3 are disabled, other heads can still operate. This can cause cold
drinks to be dispensed out of the right head(s).
