Troubleshooting manual Error messages and troubleshooting...
Troubleshooting manual Err 2 Temperature probe chamber 1 defect Err 3 Temperature probe chamber 2 defect Err 3 The error (temperature probe chamber 2 defect) concerns only unit size 20.x , because these unit has two chamber probes. Chamber probe 1 = upper chamber, chamber probe 2 = lower chamber. Consequence: The electronic changes in an emergency program automatically.
Troubleshooting manual Err 1 Core temperature probe defect Consequence: The electronic changes in an emergency program automatically. The function of the probe is deactivated. Position of the core temp. probe: In the front of the chamber. Designation of the component in the wiring diagram: Troubleshooting: Check contacting at plug X16 on the control pcb A2 .
Troubleshooting manual Err 5 Error drain temperature probe Consequence: The electronic changes automatically in an emergency program. The drain cooling switches on and off controlled by the electronic (During operation). Position of the drain temperature probe: The probe is located at the trap. Designation of the component in the wiring diagram: Troubleshooting: Check contacting at plug X11 on...
Troubleshooting manual Err 9 Over temperature cooking chamber Consequence: The unit is not ready for operating until the unit has cooled down. Error description: A temperature of >310°C (590°F) electric units or > 270°C (518°F) gas units were measured in the chamber by the Core temp.
Troubleshooting manual Err 10 Electronic to hot Err 11 Electronic overheated Consequence / description: Error: “Electronic to hot: The measured temperature of electronics amounts to at least 70°C (158°F). The cooked program is stopped. Error “Electronic overheated”: The measured temperature of electronics amounts to at least 80°C (176°F). The oven switches off itself.
Troubleshooting manual Err120 12 Volt ground error Error description: The error means, that the there´s a ground shortcut at the control pcb. The error appears after switching the unit on and is not ready to operate. Troubleshooting: Disconnect the following components one by one to identify the faulty component: Core temperature probe B1 –...
Troubleshooting manual Err 66 No water (Only at units with WaveClean) Description: The error message appears only during steaming and WaveClean mode. The error only appears if the the pressure switch realised a water pressure less than 1bar (14.5 psi). The contact opens and the message appears on display.
Troubleshooting manual Err 30 No fan 1 (only at gas units) Err 32 No fan 2 (only at gas units) Designation of the component(s) in the wiring diagram: Fan M1, frequency controller V10 (upper chamber at the 20.x) Fan M2, frequency controller V20 (lower chamber at the 20.x) Description: The electronic waits for a confirmation signal from the hall sensor (fan speed control) after the fan has started.

Troubleshooting manual The green LED on the frequency controller is off. Is the power supply at the frequency Replace frequency controller. converter provided (230V on terminal L/N)? Replace fuse. Maybe the fuse was destroyed Are the fuse(s) F1 / F2(only at 20.x) OK? by a faulty frequency controller.
Troubleshooting manual Err 33 Error Fan direction (only at gas units) Error description: The fan runs in the wrong direction. Troubleshooting: Enter the service menu, select and check both fan modes. Attention! The front panel and the door must be closed. Otherwise the door contact switch is open. If the error message comes up, there can be the following causes: D0 and D1 at the frequency converter are wrong connected (crossed) –...
Troubleshooting manual Err 71 Err 710 No gas 1 No gas 2 Err 74 Err 740 Error flame 1 Error flame 2 Error message “Error flame” available from Software V4.01 (S/N 10020294, 02/2010) Error description “No Gas”: Error “No Gas 1” (Upper burner at 20.x floor units) and error “No Gas 2” (Only at 20.x floor units; lower burner) means, that no flame has been detected after start-up by the ionisation electrode / ignition box.

Troubleshooting manual General troubleshooting: Air is in the gas pipe. Remedy: Restart unit until gas is present at the gas valve. – Low voltage. The supply voltage is lower than 15% of the nominal voltage (name plate – declaration). If there is a permanently under voltage, a lower input voltage can be switch over at glowing transformer T2/T3 and control transformer T1.
Troubleshooting manual Err 72 Err 720 Gas fan 1 Gas fan 2 Description: The speed of the gas fan is faster than 7000 rpm. or lower than 500 rpm. Error “Gas fan 1”: Upper burner at 20.x floor units Error “Gas fan 2”: Lower burner at 20.x floor units Units up to S/N 10020294 can only display the error “Gas fan”...
Troubleshooting manual Err 73 Err 730 generic gas fault 1 generic gas fault 2 Description: This error message appears if F1 has changed to F0 (flame detection from the electronic) 5 times during a cooked process, without demand from the software temperature controller (i.e. during the heat demand).
Troubleshooting manual Err 75 Err 750 Error Gas reset 1 Error Gas reset 2 Error message available from Software V4.01 (S/N 10020294, 02/2010) Ionisation box reset signal check After an error at the igniting box by the error message "No gas" or “Error flame”, a reset through the 230V signal is needed.
