Machine runs properly for a few minutes the filter light flashes and beep starts; machine then continues to tumble but without heat; pressing start button gets it going again for a few more minutes. Sometimes everything is fine and machine completes the full cycle correctly – but mostly does not.

This sounds like you have a fault with the heating circuit. You need to take out the heating element and test it, also check the thermostats – there are two on the heating element and normally one on a vent tube front.
There some videos below to help you do this we will need the full number of the identification plate to ascertain which parts you need when you have checked what is wrong.
