3-Wire Circuit Disabled — The controller cannot confirm that all 3-wire safeties are satisfied.
The controller stops the wash program and turns off all outputs.
Too Long to Steam — The temperature in the machine did not reach the specified temperature
within the configured Steam Error time. The controller issues an error but the steam valve re-
mains open. If the temperature probe senses that the machine has reached its target temperature,
the error clears and the formula resumes.
Low Steam Pressure: Do a check of the steam pressure from the boiler to the machine.
Steam Time Configured too Short: Do a check of the configured steam time in your ma-
chine’s configuration decisions. This value represents the time required to apply steam to
cold water at high level to achieve the hottest temperature used.
Steam Valve Malfunctioned: Use formula intervention to turn the steam valve on to con-
firm proper operation.
Too Long to Cool — The temperature in the machine did not drop to the specified temperature
within the configured Cooldown Error time. The controller issues an error but continues to per-
form the cooldown. If the temperature probe senses that the machine has dropped to its target
temperature, the error clears and the formula resumes.
Cooldown Time Configured too Short: Do a check of the configured cooldown time in
your machine’s configuration decisions. It may be necessary to increase the cooldown error
time.
Low Water Pressure: Do a check of the cold water pressure and volume to the machine.
Cooldown Valve Malfunctioned: Do a check of the cooldown valve for proper operation.
Temperature Circuit Malfunctioned: Do a check of the temperature probe and the ana-
log-to-digital board for proper operation.
Check Temperature Probe — The temperature probe detected a temperature below 32° F (0°
C) or above 230°F (110°C). The controller turns off all outputs, cancels the wash formula, and re-
turns to the Home display.
The Probe is Disconnected: Electrical troubleshooting is required. Check for an open
circuit.
