These error codes relate to the wireless controls fitted to the appliance, this is usually in the form of a wireless controls key fitted underneath the appliance and a room thermostat elsewhere.
There are many different types of wireless control available for this appliance so it is advisable to refer to the instructions for the controls fitted but the issue is usually a communication fault between the wireless key and the thermostat or a fault with the key/thermostat.
It is not possible to fault find directly on the key or thermostat so it is advisable to refer to the instructions for the relevant control and try powering off the appliance then powering back on.
