Liam. It is a while ago since you posted your question but if it is relevant try this. With the power switched on at the plug switch off the power at the machine using the on/off button. Press "P" and hold whilst simultaneously depressing the on/off button to switch on the machine. This should clear the lights 2 & 4. Next switch off at the plug and leave for at least 60 seconds. Switch back on at the plug and the machine should respond as normal.
