FAULT MESSAGES
In the event of fault, the display panel on the QAA73 shows the flashing symbol . Follow the procedure indicated in
paraghraph 14.2.
Note:
Remove the protective plastic coating from the boiler painted panels before lighting.
1. Ensure that the gas and electrical supplies to the boiler are off and that the cold water supply inlet valve and the central heating
flow and return valves are open.
2. Turn on the gas and electrical supplies to the boiler.
3. Ensure all external controls are calling for heat.
4. Set the hot water and central heating temperature selectors to maximum.
5. Set the selector switch to
6. Open a hot water tap, the main burner will light and the boiler will provide hot water. Close the tap and the burner will go out.
7. Set the selector switch to
fan will start; once the pressure switch is proven, the main gas valve solenoid will open allowing the main burner to light from
the ignition electrodes.
8. The safety shutoff valve device must be tested. To test this device, close the gas cock and verify that the main PCB tries to
relight the gas boiler three times. After the third attempt to relight the boiler, the display carries out the error code E133. To
reset the boiler, turn selector 1 (figure 30) to "R" for at least 1 second (see section 3.3 of the user manual).
