Cold oven CLEANING INSTRUCTIONS e2 14 SERVICING THE OVEN 14.1 Servicing Procedure: DO NOT use tools PRODUCT DETAILS REMOVE & CLEAN Oven Parts: 1. Remove the air filter at the rear of the oven by sliding upwards. 2. Open the oven door and remove the crumb filters, impinger plate and cook plate. 3. Carefully slide the grease tray forwards to remove from the oven and dispose of the contents responsibly following any applicable guidelines or regulations. Wash all parts in warm soapy water.
15 ERRORS & DIAGNOSTICS 15.1.1 A description of the type of error is shown. Check for a number following ‘ERROR:’ (A) and refer to the Error Codes (Fault Finding section) for more details. The Oven Serial Number, Model, UI (QTS) version and SRB version information is also displayed below. 15.1.2 Clear the Error message by power cycling the mains power supply to the oven (not the oven ON/ OFF switch). 15.2 COPYING ERROR MESSAGES: A B SERVICING 15.2.
16 FIRMWARE UPDATES 16.1 1 3 2 IMPORTANT: Downloading from a USB will clear all existing programs. Update the ‘SRB’ first, the ‘BTS’ second and the ‘Icons’ third (found under the USB ‘Recipe’ heading). 16.1.8 Switch on the oven and tap the top right of the screen (1) to bypass the preheat stage. 16.1.9 Enter the password and select OK to display the Settings menu, see (2). 16.1.10 Select the USB symbol (4). 16.1.
17 OVEN TESTING SERVICING IMPORTANT: Downloading from a USB will clear all existing programs. Only use an empty USB memory stick formatted as follows: A) FAT16 to update from UI QTS-XXXXXXX-V1.2.16 B) FAT16 or FAT32 to update from UI QTS-XXXXXXX-V1.2.17 or later. Copy the following firmware files to the ROOT directory of the USB memory stick: ●● QTS-eX-XXX-VX.X.XX.BIN ●● SRB-eX_X_X_XXX.BIN ●● VX-APP-eX.CBR ●● Autoupd.
A 17.4.1 Enter Service mode (Servicing section). 17.4.2 Select the down arrow to display the individual Oven tests (A) for the oven to perform. 17.5 Microwave Power Test TESTING COMPONENTS Measuring the power output. Note: The power output is established under IEC 705 standard method which is only workable in Laboratory controlled conditions. Power output is also affected by line voltage under load, so this test is an approximation only. 17.5.
TESTING COMPONENTS Measuring the oven cavity temperature. (Note; re-calibrating the Thermocouple with the SRB is normally only required when the Thermocouple has been replaced or the oven is under or over cooking.) Procedure: 17.7.1 Place the probe of a temperature reader (A) onto a heat sink in the centre of the oven cavity and close the oven door. 17.7.2 Select ‘Temperature Control Test’ (B) from the service mode tests. The oven heats up and cycles at the maximum set point temperature over 30 minutes.
18 HIGH VOLTAGE COMPONENTS High voltages and large currents are present at the High Voltage Capacitor. It is very dangerous to work near this part when the oven is on. NEVER make any voltage measurements at the High Voltage circuits, including the magnetron filament. DANGER: Before removing the oven casing, isolate the oven from the mains electricity power supply; switch off, disconnect oven plug from wall socket, turn off isolator switch to disconnect fixed wired ovens and lock-off.
19 MAINS VOLTAGE COMPONENTS TESTING COMPONENTS Located on the door hinges are 3 safety interlock microswitches, to prevent microwave emissions escaping when the oven door is opened: The Primary (SW3) breaks the electrical supply circuit to the transformers. The Secondary (SW2) breaks the microwave circuit if the primary fails. The Monitor switch (SW1) will short out the Microwave circuit blowing the fuse if both Primary and Secondary interlocks fail.
