UK appliance repair questions? Ask a technician for answers ASAP
A10 indicates a fault with heating on the appliance.
This is from the service manual.
A10 Open circuit in heating circuit.
Check out the heater, wiring, pressure switch and if they are all ok, I'm afraid you need to replace the control board in the facia.
Get back to me if you need more help.
If you are unable to do the work yourself, I'm afraid you'll need an engineer to attend the appliance.
Hope this helps
