For the above dryer, a suggestion to look at heater assembly.
Found thermal link blown. Replaced with another 180c part.

Still F04 fault display, checked all pump and filter sensors and fault now changed to F06 which points to door lock but there is no door lock. Only thing on door is a micro sw on lever which is switching on/off. Still have F06 and all sensor lights flashing.
Need some positive direction here?

Any progress with this?

Check your source of information on the F06 code.. I believe F06 is actually related to the heating element not a door switch. Sounds like the common fault where the thermostat at the back of the heater fails.
